, Patented May To all whom it Irmi/y concern:

Be it known that I, JOHN W. NEWMAKER,

a citizen of the United States, residing at Warren, in the county of Warren and State of Pennsylvania, have invented new and usef `similar articles, in which the drawers have a serpentine or swell front, va fixed pattern for these edges is undesirable for the reason that the surfaces or faces of the drawers shift slightly from a fixed pattern, and the edges of the rails should follow the contour of the face of the drawer, preferably the edge should follow the contour of the face of the drawer extending farthest' out.

In carrying out my process, I have utilized the machine illustrated in the accompanying drawings.

Figure 1 is a plan view of the device; Fig. 2 a side elevation, the frame being operated upon being in section; Fig. 3 a section on the line 3-'3 in Fig. 1; Fig. 4.- an enlarged view of a fragment of the cutter.

1-1 mark the rails on which the support for the work is carried. The car frame 2 is mounted on the wheels 3, the wheels 3 travel ing in the tracks 1. Tracks 4 are mounted on the car 2 transversely to the tracks 1, and

the plate 5 is mounted on the wheels 6, the

wheels 6 being arranged'to travel on the tracks 4.' The plate 5 has an abutment 7 at the rear side or end, and a similar abutment 8 at the front end.- A screw 9 extends lthrough the bracket 10 and operates upon the abutment or block 8 to clamp the drawer `frame 11 on the plate. The drawers 12 are provided with curved. or swell fronts 12a,

and the drawer frame has the interveningrails 13. yThe specific machine illustrated is designed to finish the edges of these rails. so as to conform to the adjacent surfaces of the drawer fronts. l

A cutter 14 is mounted on the spindle 15. This spindle is journaled in the bearings 16-16 carried by a frame 17. The frame 17 has the two sides 18l which are journaledonj A 'l a driving shaft 19. They are locked against endwise movement on the shaft bythe col lars 20. A pulley 21 is fixed on the ,spindley 15 between the bearings 16. A pulley 225s.

fixed on the shaft 19. A belt23 drivesth'e` pulley 21 from the pulley 22. The driving shaft 19 is driven in the usual mannenand isvpro'videdwith the usualtight and l. loose pulleys'f2i1 and v25, by means of which it may be driven. l

A guide 26 is pivotally mounted atithe side of the frame 17 by Ameans of the boltj 27. kA bolt 29 extends through a sl'o't4 28 in the guide, so that the guide may be ylocked in adjustment. lThis guide hasl the 'side pieces 30-30 which straddle the rail 13, as clearly shown in Fig. 3, and rest uponthe surfaces of the drawer fronts 12a. They also engage the top and bottom of the rail and thus keep the cutter central, even though the rail may bey slightly warped. Y The guide 2.6 may be adjustedby'swinging on the bolt 27, and

locking it with the bolt 29, so as to give the. i

rail any desired projection over the surface of the drawers.

The frame v17 is provided with a handle 31 and a cord 32 passes from the frame over the pulleys 33 and 34 on the beam 35. A weight 36 is secured to the opposite end of the cord, the weight being so proportioned to the weight ofthe frame as to practically balance it. extends downwardly from the beam 35 in the path. of a lug 38 on the frame. An eye 4:0 is arranged on the catch to operate it to permit the lowering of the frame to the cutting position.

In the operation of the apparatus, and in carrying out the process, a drawer frame such as a chiffonnier orbureau, is placed on the carriage and clamped by means of the block 8 and screw 9. The plate 5 can then be moved transversely, so as to bring one of the rails in line with. the cutter. The carriage is then moved forward and the cutter A spring catch 37 sufficient variation in the drawers to necessitate this. l/Vith this machine it will be observed the rail conforms to the surface of the drawer extending'farthest out, so that there is at all times a projection of the rail.

The cutter 14 is made up of a series of thin blades and these blades are provided with teeth 41 forming the cutting face. In making up the cutter the vteeth are staggered. The result is, that each cut is of so little width relative to the width of'the article being 4finished that it is not split nor chipped up when it is fed against the grain.

t is thereforepossible to shape articles i .where the patterns involve a changing ofthe grain without shifting the tool.

`What I claiml as new is:

1. The art or `proeess of finishing drawer rails of chiffonniers and the like which conrail to cut the rail, while guiding said cutter y upon an adjacent drawer.

y2. The art or process of finishing drawer rails of chifniers and the like which con-v sists in applying a rotary cutter to the rail,

and moving the cutter lengthwise of the rail tocut the rail, while .guiding said cutter by the drawers at each side of the rail whereby the drawer farthest out, in case of unevenness becomes a guide.

`3. The art or process of nishingdrawer rails of chiffonniers and the like which consists in applying a rotary cutter to the rail, and moving the cutter lengthwise of the rail to cut the rail, while guiding said cutter upon an adjacent drawer and guiding the cutter edgewise of the rail by the rail.
