ROBERT P. DE REMER, OF HOUMA, LOUISIANA, ASSIGNOR OF ONE-HALF TO ALFRED T. GERRANS, OF HOUMA, LOUISIANA.

WOODWORKING-MACHINE To all whom it may concern:

Be it known that 1, ROBERT P. DE REMER, a citizen of the United States of America, residin at Houma, in the arish of Terrebonne and tate of Louisiana, ave invented certain new and useful Improvements in Woodworking-Machines, of which the following is a specification.

This invention relates to wood working machines, and the object thereof is to provide a machine of such class in a manner as hereinafter set forth particularly adapted for cutting Gothic heads on fence pickets and posts, and is furthermore adapted for cutting round ends on the butts of shingles.

A further object of the invention is to provide a machine of such class with adjustable means in a manner as hereinafter set forth whereby heads of different contour can be out.

Further objects of the invention are to provide a machine for the purpose set forth which shall be simple in its construction, strong, durable, efficient in its use, readily set u and comparatively inexpensive to manu acture.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the preferred embodiment of the invention; but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto a pended.

In describing the invention in etail reference is had to the accompanying drawings wherein like characters denote corresponding parts throughout the several views, and in Which Figure 1 is a side elevation of a woodworking machine in accordance with this invention; Fig. 2 is a top plan view; Fig. 3 is a transverse section; Fig. 4 is a detail in side elevation showing the position of the picket in full linesjust prior to the cutter acting thereon and in dotted lines one-half of the head formed; Fig. 5 is a side view of the picket showing completed head.

Referring to the drawings in detail, 1 denotes the machine frame which is formed of a series of longitudinal, vertical and transverse bars, and, journaled, as at 2, in the top of the frame is a driven shaft 3 connected by Specification of Letters Patent.

the pulley 4. with a prime mover (not shown). The shaft 3 constitutes the operating shaft for the cutter, the latter being indicated by the reference character 5 and embodying a pair of collars 6, which are fixed to the shaft 3 and to which are attached a pair of knives 7, 8, the former extending in an opposite direction with respect to the latter and said knives being so positioned as to obtain the necessary clearance during the o eration of the cutter upon the picket 9. Tie cutter 5 is mounted upon the shaft 3 at one side of the frame 1 and for this purpose the shaft 3 projects laterally from said frame.

One side of the machine frame is provided with two pairs of uprights. The uprights of one pair are indicated by the reference characters 10 and 1.1 and the uprights of the other pair are indicated by the reference characters 12 and 13. The u rights 11 and 12 are the outer uprights, the atter being of greater length than the former. The u rights 10 and 13 are flush with the top of t e frame, while the upright 12 projects above the top of the frame and carries near its upper end a pulley 14. The u right 11 also projects above the top of the rame, but not to the extent of the upright 12. Each of the uprights 10, 11, 12 and 13 is formed with a vertically-extending opening 15, and to the outer faces of the uprights 11 and 12, and directly in front of the opening 15 is ositioned a slotted plate 16, the lower end 0 the plate being secured in position by the holdfast devices 17. Against the inner faces of the up rights 10 and 13 at the rear of the openin 15 of said uprights is positioned a slotted p ate 18, the lower one bein secured to its respective upright by the ho dfast device 19. The upper ends of the plates 16 and 18 are secured together by the holdfast devices 20. Extending through each pair of lates 16, 18 is a headed bolt 21, which is fixer in osition by the clamping nut 22. Each of t e bolts 21 also carries a washer 23 which is posi tioned in advance of the )late 16.

Arranged at one side 0 the machine frame 1 is a work-holder adapted to be swun towards the cutter .5 so that the work wil be brought into proximity to the cutter to allow of the operation of the latter upon the work so as to form the head. The work holder Which is angular in cross section has the horizontal portion thereof indicated by the reference character 24 and the verticallyextending portion by the reference character 25. The vertically-extending portion 25 is bifurcated. as at 26, 27 and extending between the furcations is the upper end of a link 28, the said upper end bein pivotally connected, as at 29, to the vertica ly-extending portion 25 of the work holder. The said vertically-extending portion is cut away so that one of the furcations of each bifurcated portion is shorter than the other, as at 30, constituting abutments adapted to engage the stops 31 carried by the uprights 1] and 12, the said stops 31 limiting the movement in one direction of the holder-that is to say, towards the cutter. The links 28 extend-in parallelism with respect to the plates 16 and each of said links 28 is formed with a series of openin s 32 which register with the openings 33 in t 1e plates 16, the openings 33 registering with the openings 34 in the plates 18. The links 28 are adapted to be mounted upon the bolts 21 between the heads 35 of the bolts 21 and the washers 23. The links 28 swing upon the bolts 21 and the length of the links is such with respect to each other that the work holder is maintained when elevated at the same level throughout; but to allow of the work holder swinging upon different arcs so as to change the contour of the head cut 11 on the picket, the bolts are adapted to be shi ted so as to extend through the sets of alining o enings between the links and lates. If t e bolts 21 are positioned at the ower ends of the links and plates the extent of movement of the work holder will be greater than if the bolts 21 were positioned at the center or to of the links and plates, but the are in whic the work holder travels would be less, and by such an arran ement the len th and contour of picket heads can be varie as will be evident for the reason that if the work holder moves u on a small arc the length of the head out wi 1 be shorter than it would be if the work holder moved through a greater are.

The horizontal portion 24 of the work holder near that end which is arranged in proximity to the cutter 5 is provided upon 1ts upper face with a resilient member 36 having one end fixedby the holdfast devices 37 to the work holder and its free end bent in an angular manner, as at 38 and sharpened. Extending through the portion 24 of the work, holder is an adjusting screw 39 adapted to bear against the free end of the member 36 so as to enable the elevating of said member when occasion so requires. The functionof the angular end 38 of the member 36 is to bite in the work to prevent the same from bein drawn off the work holder when the wor is o erated upon by the cutter. The horizontally-extending portion 24 of the work holder is formed with a plurality of screw-threaded sockets 40 which are adapted to receive a set-screw 41 carrying a nut 42. Interposed between the nut 42 and mounted upon the set screw 41 is an adjustable stop 43 having an elongated slot 44. The sockets 40, set screw 41, nut 42, stop 43 rovide means for positioning the work wit 1. respect to the holder-that is to say it enables the length of that portion of the Work which projects from the holder to be varied and at the same time enables uniformity in the length of the head out upon the work. The adjustable stop 43 associates with the angular end of the member 36 in this particular; if the work is brought against the stop and pressure applied upon the work it will cause the angular end 38 to bite into the work and assist in maintaining one end of the work against the stop.

Connected to the rear end of the work holder and passing over the pulley 14 is a flexible member 45 which extends through an opening 46 formed in the side of the frame 1 at the top thereof and also passes over a pulley 47 secured in said opening through the medium of the keeper 48. The lower end of the member 45 carries a counter-balance Weight 49, the function of which is to con. stantly pull the work holder in a direction towards the cutter. A stop 50 is secured to the side of the frame 1 for limiting the downward movement of the Work holder when it is moved away from the cutter.

The work holder having been adjusted so that when shifted it will move in the are desired, and the work having been placed upon the work holder, the latter being in the depressed position as shown in full lines in Fig. 4, the operator holding the work holder in such osltion (which is contrary to the position t at the work holder assumes when the weight is free to act) the operator now shifts the holder towards the cutter. Such action is had with the assistance of the weight 49. The position which the work holder assumes with the work after it has been shifted to an operative position with respect to a cutter is shown in dotted lines in Fig. 4. After the out has been made upon one side of the work, the holder is shifted rearwardly and the work is then turned to osition the other side thereof which is to e cut and the holder is then shifted manually towards the cutter by the operator so that the holder will assume the position shown in dotted lines in Fig. 4 when the work will be again out.
