WOODWORKING-MACHINE.

Specification of Letters Patent.

Patented Oct. 13, 1914.

The primary object of this invention is the prov sion of a machine for grooving the sides and partitions of boxes or cases designed to receive bottles or like articles to be kept separate. It is to be understood that the machine may be adapted for a variety.

of work where lumber is to be grooved or channeled for any purpose.

The invention relates most especially to the general structure of the machine and more particularly to the carriage, work clamp and adjusting and operating means.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claims.

Referring to the drawings, forming a part of the specification, Figure 1 is an end view of a wood working machine of the character stated embodying the invention. Fig. 2 is a side view thereof. Fig. 3 is a top plan view. Fig. 1 is a detail view of the carriage and work clamp. Fig. 5 is a detail View of the mandrel for receiving the cutters.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The main frame for supporting the working parts is indicated at 1 and consists preferably of end and side pieces which are cast and bolted together in any substantial way. Bearings 2 are mounted upon the end pieces of the frame and support the arbor or man drel 3, which is adapted to be driven from any suitablesource of power by means of a belt pulley 4 secured to an end thereof. Collars 5 and 6 are shrunk upon or otherwise secured to the mandrel 3 near one end thereof and are arranged upon opposite sides of one of the bearings 2, thereby preventing any endwise play of the mandrel in its bearings. Washers 7 are mounted upon the mandrel 3 and are of varying thicknesses to enable proper spacing of the cutters. The

bearings 2 are adjustable on the end pieces of the frame 1 and are moved by means of set screws 8, which are threaded into portions of the frame. After the bearings have been adjusted they are made fast by means of bolts or machine screws in the manner well understood. A carriage support is mounted upon the main frame and is adjustable vertically to regulate the depth of the grooves or channels to be cut in the work. The carriage support embodies guide bars 16, which are arranged at opposite sides of the frame and have grooves or channels in their upper sides to receive posts or slides 17. The grooves or channels are of wedge form to receive the lower ends of the posts 17 which are of corresponding shape, thereby retaining said posts in place upon the guides. Shafts 9 support the guides 16 and are provided with like screwthreads and engage nuts 12, which are mounted between lugs or projecting parts 14 of the main frame. Each of the nuts 12 has a bevel gear 12*, which is in mesh with a bevel gear 12* secured to a shaft 13. A shaft 13 is had for each end of the machine and isprovided with two bevel gears 12*, which mesh with the bevel gears 12 of the respective nuts 12. A sprocket chain 11 connects sprocket gears 10 secured to the shafts 13. Rotary movement imparted to one of the shafts 13 is transmitted to the other shaft by means of the sprocket chain 11. The parts are of such relative pro-portions that the guides 16 are moved so as to remain parallel to a given position at all stages of adjustment. Motion is imparted to one of the shafts 13 by means of a hand wheel 12 which is secured to the outer end of a short shaft, the latter having a bevel gear 12 atits inner end which is in mesh with a bevel gear 12* secured to the shaft 13.

Bars 15 are mounted in the posts or slides 17 and are adapted to be connected by rods or bars 28 which hold them spaced apart the required distance. The bars 15 support the work. An intermediate bar 18 is located between the bars 15 to support the work at a point between its ends. The intermediate bar 18 is likewise supported in posts or slides 17 and its outer ends also receive the rods or bars 28. Posts 19 are secured to the bars 15. Other posts 20 are adjustable on the bars 15 and are secured in the adjusted position. Braces 26 secured to the posts 20 119 extend therefrom parallel with the bars 15 and are adapted to be adjustably connected to posts 27 fixedly connected to the outer ends of the bars 15.' Each of the braces 26 has a longitudinal slot 26 in its outer end through which passes a bolt or fastening 26 fitted to the post 27. hen the fastening 26 is loosened the brace may be moved to adjust the post 20, the latter being secured in the adjusted position by retightening the fastening 26 A jaw 21 is mounted in each of the posts 20 and serves to grip the work which is placed upon the bars 15 and 18 between the posts 19 and 20. A shaft 29 is mounted in the posts 20 and is provided with cams or eccentrics 22, which engage the jaws 21 so as to project them toward the posts 19 to grip the work when in position. A lever 80 is secured to one end of the shaft 29. In order to admit of the adjustment of the bars 15 the shaft 29 is adapted to move through one of the postsv 20 and has a feather and spline connection with the eccentric or cam 22 supported by such post.

The several bars 15, 18' and 28 constitute a carriage upon which the work is held and moved over the cutter, the bars 15 and 18 being slidable in the posts 17 and the carriage being reciprocated by hand. The bars 15 are spaced apart the required-distance to suit the work, after which they are secured to the bars 28 by means of set screws 31. The carriage is held in a desired position upon the guide bars 16 by means of set screws 32 let into posts or slides 17.

A gage 23 is had for properly positioning the work upon the carriage. This gage is vertically adjustable upon a post 24-, which in turn is adjustable upon one of the guides 16, said adjustment being effected by means of a set screw 25. The gage serves to even the work when placed upon the clamp or holder. After the carriage is drawn out to bring the work holder in front of the cut- .ter, as shown in Fig. 3, the pieces to be grooved or notched are placed in. position upon the bars 15 and 18 and are clamped between the posts or jaws 19 and 21. The carriage is now pushed in to move the work over the cutter and is'again returned to a normal or starting position for readjustment of the work or replacement of the same by new pieces.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while we have described the principle of operation of the invention, together with the device which we now consider to be the best embodiment thereof, we desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is

1. In combination, transverse bars, longitudinal bars adjustably connecting the transverse bars, two posts secured to the transverse bars, a third post for each of the transverse bars mounted thereon between the said two posts, a brace connecting each of the third posts with one of the two posts, a aw mounted upon each of the third posts, a shaft paralleling the longitudinal bars and mounted in the third posts, cams mounted upon the shaft, one of such cams having a feather and spline connection with the shaft to move thereon and means for turning the shaft.

2. In combination with guide bars, slides mounted upon the guide bars, transverse bars mounted in the slides and adjustable therewith, relatively fixed and movable work engaging jaws mounted upon the transverse bars and operating means for the movable work gripping aws having adjustable connection with the transverse bars to move therewith and admit of such work gripping jaws being adjusted toward or away from each other.

In testimony whereof we ailix our signatures in presence of two witnesses.
