SPECIFICATION forming part of Letters Patent No. 534,090, dated .October 3, 1899. Application filed February 23, '.LSQQ. Serial No. V706,459. (No model.)

Tol all wiz/0m t may concern-s Be it known that I, FREDERICK G. MOTT, a citizen of the United States of America, and a resident of Utica, Oneida county, New York,

have invented certain new and useful Inl-vf proveniente in Cone-Adjusters and Nutis a specifica'-l Locks, of which the following tion. Y z p My invention relates to acone-adj uster and nut-lock; and it consists in the mechanism` hereinafter pointed out and claimed.

In the drawings, Figure 1 1s a vertical cer-L tral section of a ball-bearing axle with my;

improved adjuster and nut-lock in position.

Fig. 2 is a central section of the saine on line` C D. F1g. 3 is a cross-section on line A B of Fig. l. A Fig; isa perspective viewillustrating details of a thiinble'.. Fig. 5 represents a vertical central section of a hub with my irnproved cone-adjuster and nut-lock'applied,

broken lines indicating parts removed, por-v tions of the axle being shown in full lines.V

In rubber-tire vehicles and light road-wagons where ball-bearings are used it is Aiinportant to provide some eiective as well as delicate means for adjusting the bearings'of the parts, so that the parts may be held in ,the given position to'which they are adjusted,

and when in this position they may be locked f opening or tubular portion of the axle has' suitable screw-threads 5 from the outer end inwardly, forming at the bottom of the opening shoulder 6. Into the outer end of the central opening/l in the end .of the axle I fit a hollow screw-threaded adjuster 7. rl"he screwthreaded adjuster is provided on its extension Iil with suitable screw-threads correspondingl with thescrew-threads in the opening in the axle. vThe adjuster has alongitudinal opening`9 through its length, the opening being .preferably smooth. The adjuster 7, provided with' screw-threads registering with the 'threads in the tubular opening in the axle, permitsfthe adjuster to be turned down by a wrenoh'to the nicety of adjustment desired, sothat thewheel and its various bearings can be made to cooperate in running loosely and yet tightly, which constitutes the essence 'of a ball-bearingvehicle. i For locking and securing the parts I provide tubular screw-threaded non-rotating jtliimble 10, Fig. Ll. The tubular opening 1l ,through the saine is provided with screwlthreads 12. On the inside of the non-rotating thimble, for preventing the thiinble from rotating, I preferably cut the portion of this circular body into flat form 13 on opposite sides of the thimble. Any other method of keeping the thimble from rotating may be employed, the intent being to keep the thimble from rotating and yet permit it to move in the vdirection of' the length of the axleopening. 'The thimble is placed loosely in the tubular opening in the ends of the axle at the bottom of said openings. In order to lockV the adj uster when it has received the requisite adjustment, I provide set-screw 14, which is inserted through opening 9 1in the adjuster. The screw-threads 15 on the end Vof set-.screw 14 are turned and screwed into opening 12 in the thimble. By turning the set-screw in the thirnble the latter is drawn up into contact with the end face of the adjuster, thereby locking the parts together. For preventing collar 15 from assisting in working loose from the adjuster "7 I key collar 15fL to the end of the axle at 15b. The ihiinble 10 in this instance is prevented from rotating in the bottom of the axle-opening by pins 16 16, Figs. 1, 3, and 5, which in this instance pass through the axle, the pins being inserted through suitable openings in the axle, so that the pin will pass over the flat surfaces 13 13 of the thimble on either side, the thimble being provided at its sides with cut-away surfaces, which permits its end movementwhen set-screw 14 is turned in the thixnble, so that the end 17' of the set-screw' rests against the bottom of the tubular opening in the axle. By turning the set-screw the thirnble is drawn into locking contact with the face 18 of thev thiinble by bringing` the end thcreofinto contact with the end 1f) of the adjustcrand when sufficiently tightened Will hold adjuster 17 in a fixed position to which it may have been adjusted, so as to give the appropriate bearing to the Wheel for securing the best results.

For maintaining the balls in their seat I provide band 20, slipped over the axle in one instance and over the collar on the axle in the other, and for excluding the dust from the parts I provide leather Washers 2l 22, Fig. 5, and at the opposite end Iprovide felt packing 23,-the parts being held together by screw-threaded cap 24, so that balls 25 will carry the load, and by the arrangement of the adjusting and locking mechanism the parts may be adjusted and locked into the desired degree of tension for securing most satisfactory results in aball-bearing axle. The hubs v26 are provided with ordinary metal spoke 27 and are arranged in common form in ballbearing axles and will be sufficiently underf stood without further explanation.

What I claim as new, and desire lo secure by Letters Patent, is-

l. An axleprovided with a screw-threaded opening in its ends, the combination with tho tubular screw-threaded non-rotating thimble in the axle-openings, a set-screw for engaging the thimble and moving the same in the direction of the length of the opening, for the purposes stated. j

2. An axle having longitudinal screwthreaded openings from the outer ends thereof, in combination with a tubular screwthreaded adjuster, a non -rotating screwthreaded thimlole in the openings arranged to move in the direction of the length of the openings, and a set-scrcwfor theV purposes stated.

3. An axle provided with openings from its outer end in the direction oi' its length, a tubular movable adjuster Working in the axleopening, a non-rotating tubular thimble arranged to move in the direct-ion of the length of the axle-opening in the bottom of the axleopening and a set-screw for moving the thimble into contact with the adjuster. for locking the parts, substantially as set forth.

4'. A tubular axle provided with screwthreads in the tube, in combination with a tubular screw-threaded adjuster, a movable non-rotating screw-threaded thimble and a set-screw, for the purposes stated.

5. .A tubular axle having internal screwthreads at its ends, a tubular screw-threaded adjuster, in combination with a screw-threaded thimble arranged to move in the direction of its length and mechanism for preventing the rotation of the thimble and the set-screw operatin g the tliimble, for the purposes stated.

6. A tubular axle provided with screwthreads in the tubular ends of the axle, in combination with a tubular screw-threaded adjuster, a tubular screw-threaded thimble having one or more of its outer surfaces vflattened, a pin for preventing the thiinble from rotating, and a set-screw for operating the thimble, for the purposesstated.

Signed by me,at Utica, New York, this 28th day of January, 1899.
