To all whom at may concern:

Be it known that 1, CHARLES H. AMIDON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and n sefni Improvements in Planhrg-Machines, of which the following a specification.

My invention relates to manually-open ated planing-machines of that ty ewhich can be conveniently carried from ace to place and he applied to a vise for ho ding the same in an operative position.

The primary objects of this invention are to provide a planing-machine of this character which is simple, positive, inexpensive, and durable, and in which a uniform and smooth forward or cutting stroke can he maintained at all times, and to rovide a machine in which the sliding too holding carriage is IHOVPll back and forth independent of the feed-carriage.

Further objects are to provide mechan ism whereby the amount of feed may be varicd at will and to improve and simplify plan ing-machines of this type'in genera With these objects in view the invention consists of a frame which with the Work to bc planed is held rigidly in a vise, a feed-carriage movable laterally on the frame, and a sliding tool-holding carriage movable on the" feed-carria e at right angles to the movement thereof, and a variable-feed mechanism movable partly with the feed-carriage and partly with the tool-carriage, the two parts coasting when the toolbar-na e is operated. It further consists in the new and novel arrangement and combination of parts, as will:

be hereinafter more fully described, and par;

ticularly pointed out in the subjoined claims.

To show the application of or the manner {within certain tgoi of the machine to travel on a perfect.

' hand-bar 1? to tmjn the same.

a vise which I will designate oythe numeral 1 andjshich consists of two cooperating parts havingrespectively, a fixed jaw 2 and a slidable 1jlavv 3, said vise being secured to a workhens as is common.

The frame of the machine is designated by the numeral 4 and comprises side bars 5, connected at their forward ends in any approved manner to a front connecting bar or plate 6. Transverse guide rods 7 are provided on which the laterally-movable feed-carriage S is guided. The said uide-rods serve also to tie the side bars 5 o the frame rigidly togather and have their reduced ends passing through said bars and securing-nuts 9 screwed onto their projecting ends.

frame to bring the same in upper relation to the fixed jaw of the vise and hold the same in such relation; The lower end of this screw bears upon the movable member of the vise; but in addition to this support the front her or plate with the work to be planed is locked hetiveen'the two jaws of the wee, thereby supporting the forward end of the frame in a and positive manner. The rear end of the frame is supported by' tivo ad justingscrews 12, which rest on the Work-bench and liege their threaded upper ends engaging siiiiii'rlv ilhreaded apertures formed in the res seed of the side bars 5 of the frame. It is esersrss apparent that the res; of the frame can be adiusted to any desired position imits to cause the cuttinghorizontal plane or at an angle thereto,as .111? be desired; V laterally-movable feed-carria eis guided ;in its iaess onthe guide-r0 s 7 and is sense. w p d es 14, Serving, with caps 15, bolted thereto, to act as guides to ermit of movement of the carriage on sai rods. A feed-screw 16, arranged parallel to the line of movement of the feed-oarriage is. secnredivith its ends in the side bars 5 of'the frame andrat one end thereof has a V This feedscrew is by preference threaded at one end only and 'engaesa threaded depending log ing the feed serew, depending on the direc An adjustmg+serew 1O enters a threaded bore 11 formed the front bar 6 and has suitable means to permit of turning the same in its socket for adjusting the front end of the 18, formed on; e feed oarriage, whiehflfies is moved laterally in eitherdirection on torn tion in which the latter is turned. In order to move the feed-carriage intermittently, a l feeding device is provided, which is actuated. l only on the return movement of the toolholding carriage. This device consists of a bracket 19, secured to the feed-carriage and. of necessity movable therewith, and in this bracket is a ratchetwheel 20, which is secured to the feed-screw by means of a spline 21, which causes the said ratchet-wheel to turn with the feed-screw, but permits it to move lengthwise thereon. Located between the ratchet-wheel and the side bar of the bracket and mounted to turn loosely on the feed-screw is a ratchet-arm 22, having a ratchet dog or pawl 23 pivoted thereon. As shown in Fig. 5, the ratchet-pawl is doubleacting and can be swung on its pivot to revolve the ratchet-wheel during the forward or rearward movement of the ratchetarm, as may be desired. By 'ireference, however, the ratchet-wheel is revoived during the rearward movement of the ratchet-arm, which takes place simultaneously with the return or ino erative movement of the cutting-tool, as wil be disclosed hereinafter.

Longitudinal guide-bars 24 are secured in upwardly-projecting lugs 25, formed on the upper face of the feed-carriage, and movable on these guide-bars is the tool-holding carriage 26, which has laterally-projecting apertured guide-lugs 26", which encircle the said guide- 3 rods and guide the carriage in its movement. To the said tool-holding carriage I secure an arm 2", on which is supported, by means of a screw 28 an adjustable trip-bar 29, having a longitudinal slot 30, through which said screw passes. By loosening the screw the trip-bar 29 may be moved on the arm 27. which causes the trip tooth or projection 31, formed on said trip-bar, to engage the ratchetarm 22 sooner or later on the movement of the tool-holding carriage, depending on the adjustment of the bar.

The tool-holding carriage is reciprocated by an operating-lever 32, which. may be of any suitable length to give the desired leverage. The said lever lies transversely of the machine and is pivotally secured with one end to the feed-carriage, as at 33. It is also connected to the tool-holding carriage by means 1 of a link 34, pivotally connected with one end to a lateral extension 35 on said operating-lever and to the forward end of the tool-holding carriage, as at 36. This connection prevents binding of the carriage on the guidebars on moving the operating-lever, which permits of a free and easy movement. If d esired, the guides on the reciprocating toolcarriage may be constructed in. like manner to the guides on the feed-carriage to permit of taking up the wear which may be brought on by the constant use of the parts.

On reciprocating the tool-holding carriage the trip-tooth of the trip-bar 29 engages the ratchetarm 22 on the rearward movement of the carriage and through the agency of the pawl 23 causes the ratchet-wheel and the feed-screw to turn. This movement of the feed-screw, owing to the threaded connection thereof with the feed-carriage, moves the latter laterally suliicient to present the cuttingtool to a new or uncut portion of the work. On the forward or working stroke the ratchetarm 22 is engaged by the arm 27 and moved forward. This movement, however, does not revolve the ratchet-wheel, but simply causes the pawl 23 to ride idly over the ratchet-wheel to a point where it may again engage and revolve the same on the rearward movement of the carriage. It is thus apparent that the feed-carriage is moved laterally intermittently and only during the inoperative stroke of the cutting-tool.

W'hen the entire face of the work is planed and new work is clamped in the vise, it may be necessary to start the planing of the same at a certain )oint or at least at a point dif 'ferent from that over which the cutting-tool is located, and in order to move the tool to any point desired the feed-screw is turned by means of the hand-bar 17, and thus the feedcarriage is moved and with it the tool-holding carriage, on a part of which the cuttingtool is held.

To the front end of the tool-holding carriage a verticallyadjustable tool-holder 37 is secured. An. adjusting screw 3b passes through apertures 39 in the said carriage, the lower one of which is threaded for engage ment with the screw, and the head formed on the lower end of the latter bears against the under side of the toolholder, serving to elevate the same when. the iL(ljllStill{-S(ZI'(WV is turned in one direction. A thumb-nut 40 is pinned or otherwise secured to the upper end of the said adj ustingscrew and bears against the upper face of the tool-holder, serving to lower the same when the adjusting-screw is turned in. the opposite direction. The said thumb-nut serves as a convenient device for turning the adjusting-screw, which threads itself upward or downward in the tool-holding carriage and necessarily moves the toolholder in a like direction.

Pivotally secured to the verticallyadjust ablc tool-holder and forming part thereof is an apron 41., which is held between two jaws 42 to prevent lateral movement thereof. A cutting-tool 43 is clamped between the said apron and a transverse bar 44, having apertures through which stud-bolts 45 pass, which are secured to the said apron. Nuts 46 are provided to securely clamp the tool between the apron and the said bar. By loosening the nuts 46 the tool may be set to approximately cut the desired thickness from the work; but when a fine and absolute adjustment is required the tool-holder must be adjusted by turning the adjusting-screw 38.

The apron i1, owing to its pivotal connection to the tool-holder, may swing forward to enable the tool to be lifted on the rearward stroke of the tool-carriage to clear the out If desired, the frame may be rigidly secured to the fixed iavv of the vise or it me Y be formed therewith; but in practice I have found the arrangement shown in the drawings to form a very convenient device.

Having thus described my invention, What I claim is- 1. In a hand planing-machine, the combination with the frame having a rcvoluhle screw arranged therein, oI a transverselymovable feed-carriage having threaded connection with said feed-screw, feedin mechanism carried hysaid feedcarria ean adapted for engagement with said tied-screw, a tool-holding carriage located on the feed-carriage and being longitudinally movable thereon, a trip-bar adjustably secured to said tool holding carriage and adapted to actuate the feed mechanism on operating the said toolholding carriage to cause the feeding mechanism to move lengthwise on the feed-screw and move the feed-carriage in one direction, and means for revolving said feed-screw to cause the feed-carriage to move in the opposite direction, substantially as set forth.
