ADJUSTING MEANS FOR MACHTNE-GUNS OR THE LIKE.
Application filed November 5, 1914.
To all whom it may concern:
Be it known that I, DAVID GUSTAV SJo UIs'r, a subject of the King of Sweden, residing at Stockholm, in the Kingdom of Sweden, have invented new and useful Improvements in Adjusting Means for Machine-Guns or the like, of which the following is a specification.
This invention relates. to adjusting means for machine-guns or the like, and has for its object to facilitate firing at marks which are extended or located obliquely or in any other position, as for instance, at soldiers scattered over a sloping field, 2'. 6. between wings situated at different levels or in such manner that the distances between the two wings and the gun are unequal, or in both of said cases. For this purpose the gunbarrel has hitherto been connected with adjusting means so constructed that said means, after being adjusted successively atone point of the mark and then at another point thereof, elevates automatically the gun so that all points of the mark will be hit. The principle of this device previously known is chiefly founded on the arrangement of an adjustable guide, which is inclined in accordance with the oblique mark by being adjusted at different points thereof. \Vhen a member connected with the barrel then is moved in the said guide, the barrel will be elevated in the manner described above. Said device as hitherto constructed, is inconvenient in many respects, and on account thereof, has not been used to such an extent, as could be expected from the practical value of the invention. One inconvenience, especially, consists in this that the member movable in the inclined guide is connected directly with the barrel, mounted as usual in the adjusting device for vertical and horizontal elevations. Owing thereto, the arrangement is not only less accurate but also complicated and delicate as well as heavy and expensive to make. Besides, the connecting and disconnecting of the barrel is ditlicult.
The object of my present invention is to remove these disadvantages by rendering the device simple, stable and accurate in operation as well as easy to operate and able to endure percussions and shocks, being Specification of Letters Patent.

Serial No. 870,487.
lmportant qualities for practical use of the same.
Another advantage of not less importance 1s also gained on account of the easy mounting and dismounting of the barrel.
The invention is chiefly characterized by this, that the member, movable in the inclined guide, forms a part of a mechanical system preferably a parallelogram-guide for transmitting to the barrel the sliding motion of the member movable in the inclined guide.
A suitable embodiment of the invention consists in passing the member sliding in the adjustable guide longitudinally through a member preferably of cylindrical shape and adapted to be secured to the stationary part of the adjusting means by a locking device comprising two members adjustable relatively to each other, one of which forms a support for or, if desired, constitutes the adjustable guide.
The advantages mentioned above may be attained by means of the device shown in the accompanying drawing in which Figure 1 is a sectional side view of the device. Fig. 2 is an end view and Fig. 3 is a top view of the same.
The stationary part, or in other words the part of the adjusting device adapted to be secured to the gun-carriage comprises a sleeve or ring 1, provided with arms 2, the outer ends of which form bearings 3 for trunnions, journaled in the carriage. The carriage shown consists of a tripod 40, but any other suitable construction may be used. The whole system shown in the drawing may be swung in the vertical plane about the trunnions in the bearings 3 one of which, as shown inthe drawing, is connected with an elevation arc 4 cooperating with a locking device 41 on the tripod, and by means of which the whole system may be locked in the elevated position desired. Outside the ring 1 is mounted another ring 5 integral with a cylindrical member 6 and adapted to be secured to the ring 1 by a locking device 19 of any known type. Inside the cylinder 6 is rotatably mounted another cylindrical or cup-shaped member 7 retained in the cylinder 6 by means of threads or any other suitable means. The ends of two parallel guide bars 9 are secured inside the member 7 as shownnn..oro ss,. .sect1on in F g. 1,, the. sides of the guide bars fac ng each Qthenbfe;
ing planed ofii. The said guide bars f o rm the guide mentioned above which be position of the mark.
able and swingabletubular member '10,
pivoted at the inner end by meansof a joint 11' on two lugs 12, integrafwith'aring 1'3,
movably inserted in the ring-1. Therswinging movement of the tubular member 10 along the guides 9 is eflected by turningthe ring 13 inside the ring 1. The rings 1,. 5' and 13 are connected-with eaclrother. by means of threads 14: and 15 or any other suitable connecting means. From the inner ring 13 arms 16 project upwardly the upper ends of which form bearings 17 supporting a frame or cradle 18, adapted to be swung in a vertical plane and provided at the foremost endwith bearings 20 supporting the trunnions of the barrel.
In order to secure the barrel to the cradle the latter, at its rear end, has a swingable bar 21 provided with a slot 22 (Fig. 1) which by swinging the bar 21 can be turned upwardly to permit a stud or the like provided on the barrel to enter the slot 22. When the bar is swung back and the slot is turned into locking position, as shown in Fig. 1, the barrel will be locked to the cradle 18. The operations for securing the barrel to the cradle and for releasing the same may, therefore, be performed very easily since only a simple manipulation of turning the bar 21 is required.
The bar 21 does not only constitute a locking device-but serves also as a fulcrum for a connecting member 23, connected with the cradle, the lower end of the member 23 being pivoted on a lug 24, projecting from a sleeve 25, screwed onto the rear end of the tubular member 10. The member 23 may also be journaled directly in the tubular member 10. The aforesaid members viz. the cradle 18, the ring 13 with the arms 12 and 16, the tubular member 10 and the member 23 form together a parallelogram-guide, by means of which the motion is transmitted from the guide 9 to the barrel when the latter is moved in-the manner described above. The corners of the parallelogramguide coincide with the centers of motion A, B, C and D. In order to prevent the recoil of the barrel from disturbing the transmission of motion of the mechanical system A, B, C, D, the barrel should, preferably, be so journaled in the bearings 20 of the cradle, and so connected with the con necting member 23 that the axis of the bar rel coincides with a plane through the geo metrical axis of the bearings 17.
Theinechanism by means ofv which the flalrjniember {19f may be swung outwardly from the center as will be more fully de scribed below. Thell lember 7 is divided in two segments 7 and 7' by a slit 27. Inserted v in the portion 7 is a bolt 28, entering a rec ess2'9 in the portion 7. The bolt' 28 is vguidedinwa sleeve 30 projecting from the portion 7 and screwed onto the outer surface of the sleeve'30 isa'handle 31 or the like "which is also screwed onto the outer end of the bolt' 28. By turning the handle 31 the bolt 28 will enterinto or move out of the recess29. In thefirst case the segments 7 and 7 will be moved apart and pressed against the inside of the member 6, and in the latter case the segments 7 and 7 will be released from the member 6 so that they can be turned in the same, thus effecting the adjustment of the guide 9. After the adjustment the members 7 and 7 are secured by screwing the threaded bolt 28 into the recess 29. Any suitable locking device may, however, be employed.
A spindle 32 inserted in the tubular member 10 may reciprocate therein and may be moved inward by a spiral spring 33, surrounding the outer end of the spindle and bearing wlthv one end agalnst a flange 3% on the inside of the sleeve 25 and with the other end against a boss 35 of the spindle. Screwed onto the outer threaded end of the spindle is a handle 36 which can be turned and moved longitudinally in the sleeve 25 A pin 37 is inserted in an aperture traversing the spindle 32 as well as in apertures traversing a sleeve 38, movable along the member 10, and in oblong apertures 39 in the member 10. By the action of the spring 33 the sleeve 38 enters a corresponding seat of the aperture 26 (Figs. 1 and 2) thus locking the tubular member 10 so that it cannot be swung laterally. In order to permit the tubular member 10 to swing laterally in the guide 9, the sleeve 38 must be released, which is effected by pulling the spindle 32 by means of the handle 36, there by causing the sleeve 38 to move out of the member 7. In the retracted position the sleeve 38 is maintained by turning the handle 36, the portion of which entering the sleeve 25 together with the inside flange 34 of the sleeve form a bayonet'lock that holds the handle in retracted and turned position. Any other locking device may, however, be used for securing the sleeve in itsretraoted position.
The adjusting device, described above operates as follows. During the first moment of the adjusting operation when the or. nearly at the center of the mark, the lockand the member 6 as well as the remaining parts connected therewith can be swung laterally around the ring 1. Simultaneously the tubular member 10 is kept secured to the hollow member 7 by means of the sleeve 38. The adjustment of the barrel can, therefore, take place in the horizontal as well as in the vertical direction, on the one hand, by turning the ring 5 around the ring 1 and, on.
the otherghand, by turning the latter ring in the vertical plane around the trunnions journaled in the carriage. The ring 1 is then secured to the carriage and the ring 5 is secured to the ring 1 by means of the locking device 19. Then the second movement of the adjusting operation may be performed by pointing, preferably, at or nearly at one end of the mark. For this purpose the handle 36 is retracted and turned so that the sleeve 38 is released from the segment 7 thus allowing the member 10 to swing, and then the handle 81 is turned so that the bolt 28 is retracted from and releases the segments 7 and 7 which,'on account thereof, will be permitted to turn in the locked member 6. Then the adjustment is efiected, i. e. the barrel is swung in the direction from the center of the mark up to the highest, or down to the lowest wing with the elevation required by the angle between the mark and the firing direction. WVhile the ring 13 supporting the cradle 18 and the barrel respectively are turned in the ring 1 the cradle 18 together with the barrel will also be swung around the trunnions of the cradle on account of the change of elevation, which latter swinging movement together with the first mentioned lateral swinging motion will then be transmitted to the guide 9 by the parallelogram-guide A B C D, causing the guide to adjust itself obliquely according to the inclined position of the mark. The handle 31 is then turned, so that the bolt 28 is pushed into and secures the members 7 and 7 2'. 6. locking the guide in the inclined position. The sleeve 88 is still kept retracted from the segment 7, allowing the tubular member 10 to swing freely. The swinging movement of the tubular member 10, preferably effected by means of the handle 36, along the inclined guide 9 will swing the barrel along the oblique mark, at the same time elevating the barrel automatically to coincide with all points of the mark in different horizontal planes or at different distances of the same.
It is to be understood that the invention is not limited to the constructional form described above, which is intended to serve only as an example of a preferred embodiment thereof but may be performed and modified in different manners without deviating from the scope of the invention.
Having now fully described my invention and in what manner the same may be performed, what I claim and desire to secure by Letters Patent is 1. In an adjusting device for machineguns, the combination of a support, a guide movably connected with the support and adjustable to inclined positions relatively to the horizontal plane, and a parallelogram device for transmitting motion to the gun and having one member movable in the guide, substantially as and for the purpose set forth.
