To all whom t may conoem.'

Be it known that I, HENRY E. Mon'roN, a citizen'of 'the United States of America, residing at Muskegon Heights, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Heads for Draw-Cut Shapers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a draw cut shaper and especially to a movable type of head adapted to be used on said shaper or other similar tools such as metal planers and the like in which a cutting tool is drawn back and'forth over the work acted upon or the work is moved back and forth with respect to the cutting tool which may be relatively stationary. Itis the object and purpose of my invention to provide a device which on one motion of the tool Vwith respect to the work or of the work with respect to the tool will take a roughing cut while upon the return movement another tool will operate upon the Work to 'make a iinishing cut, in this manner greatly reducing the time heretofore used in machining metal parts. A further object of the invention consists in the provision of a tool of this character in which a great number of heads may be used at different times for different characters of work. For an understanding of the construction by which these ends together with others'not'specically enumerated are attained, reference may be had to the accompanying drawings, in which;

Figure 1 is a side elevation of a draw cut shaper having my invention applied thereto.

Fig. 2 is a side elevation of the mechanism showing the head carrying the tool for accomplishing the finishing cut.

Fig. 3 is a front elevation of the head.

Fig. 4 is a plan view thereof; and

Fig. 5 is a side elevation similar to Fig; 2 but illustrating adifferent type offhead.'

Like reference characters refer to like parts throughout the severa'l views of the drawing.

The frame of the shaper indicated at 1 has positioned in front thereof a bed 2 upon which the work is laid. This bed may be adjusted vertically by anysuitable adjusting means shown at 3, it being supported at its' front vend by a suitable support 4 which may also be adjustable for various positions of the bed. The ram 5 of the sha per is mounted for movement back and forth adjacentv the upper portion of the frame 1, the mechanism for operating the ram not being shown in the drawings as it 'forms no part of the invention. The front end of the ram 5 carries a supporting head 6 which may be attached in any suitable manner to the ram, and held in position by set screws 7. rIhe supporting head is located horizontally and is provided on its front face with a T-shaped slot 8 .receiving a bolt head 9 of Asuch formation as to lie within the wider portion of the slot and have a part project forward a short distance into the narrower portion thereof. The present construction shows tool supports known ordinarily as clapper boxes which are carried by two bolt heads 9 located in the slot 8. In front of each bolt head 49 a saddle'v 10v is positioned,

each of which has an adjusting screw 11 passing horizontally therethrough7 the ends of the adjustingscrews in the two saddles being joined by a screw threaded connection as indicated in Fig. Each saddle is formed with an upwardly extending part 12 on which -slhung a. swiveling block 13 which at its upper end is provided with a slot 15, a bolt 16 extending from the proj ecformed in their sides in which cutting tools 18 and 19 are mounted, these tools being retained in vposition by means of set screws 20. Thev cutting tool 18 carried by the clapper bo'x 17 is located with its cutting edgein the rear while the tool 19 carried by the opposite clapper box 17 a has its cutting edge positioned' directly'- opposite. A bolt 21 lpassesv through the clapper box, saddle, swiveling block and bolt head as indicated in dotted lines in Figs. 1 and 2 and on its outer end carries a nut 22, the parts in this manner being secured together. The clapper box 17 a has a plate 23 interposed between it and the nut 22, this plate,-however, not being used with the opposite clapper box as shown.v

The clapper box 17 has a limited pivotal movement on the extension '14 about the transverse pin 24C so that its tool 18 on the forward working stroke thereof, will move slightly to the rear but on the return stroke when no work is done by it may be moved forward as it moves'over the work without acting thereagainst. The opposite clapper box 17a is similarly pivotally mounted on a pin 24a shown in dotted outline but it will be observed that this pin is located adjacent the front side of a clapper box while pin 24e is located adjacent the rear side so that the pivotal movements of the two clapper boxes are the reverse of each other, and when the tool carried by one is working to make a cut on the work located on bed 2 the tool carried by the other is passing freely over the work and does not act thereon. Accordingly, with the forward stroke of the ram the cutting tool 19 takes a cut from the work while on the return stroke the tool 1S takes its cut, in this manner causing` the ram to operate upon the work in both its forward and rearward strokes. It will be evident that with one of the tools set for a roughingcut and the other a finishing cut, a piece of work may be entirely finished without requiring the double passage of the ram and the tools carried thereby over the work as has been required heretofore. The clapper box 17a is provided with the bearing plate 28 to serve as a stop against too extreme movement of the clapper box during its working stroke.

Each cutting tool 18 and 19 may, if desired, be provided with a channel like positioning member 25 through one flange of which passes a set screw 26, its end bearing against the tool. With one of these attached adjacent the upper end of a tool, it may be located in a desired position, in a clapper box 17 or 17a the member 25 seating against the upper end-and properly positioning the tool which may thereafter be removed for grinding or the like and replaced in exactly the same position.

In Fig. 5 I have shown a modified form of head in which a clapper box 17" similar in most respects to the one indicated at 17, but extending a distance lower, and pivoted on a similar pin 24 is provided on its under face with a horizontal slot 27, this slot extending substantially the full width of the box and adapted to receive a wider finishing tool 28 which is held in position by set screws 29. One of the salient features of my invention and one of great importance is that various types of heads may be used interchangeably on the ram and in Fig. 5 I have illustrated a different kind of head which may be used in place of the one shown in Figs. 1 and 2. Y

Changes in detail of construction may be resorted to without departing from my inlocated in front of each saddle having a slotv in its upper portion, a bolt passing from the saddle through the slot, a nut on the bolt, a tool holding support on each swiveling block, each mounted on a horizontal pin extending through the block, the pin in one block passing through the support adjacent its rear side and above the middle thereof, while the pin in the other block passes through the other support adjacent its front side and above the middle thereof, a.

tool carried by each support the cutting edges thereof being located opposite to each other and a bolt extending through each bolt head, saddle, swiveling block and tool holder Y and provided with a nut at its forward end for securing said parts together in fixed relation to each other and the supporting head.

2. In combination, a supporting head, a pair of bolt heads carried by the supporting head, a saddle in front of each bolt head, an adjusting device extending through each saddle, said devices being adjustably connected together, a swiveling block positioned in front of each saddle having a slot in its upper portion, a bolt extending through said slot and carried by the saddle, a nut on the bolt, a clapper box carried by each swiveling block, said clapper boxes being mounted on horizontal axes one located above the middle and adjacent the rear face of a. clapper box and the other above the middle and adjacent the front face of the other clapper box, means for detachably securing a cutting tool in each clapper box with the cutting edges thereof positioned oppositely, a bolt extending through each bolt head, saddle, swiveling block and clapper box, and a nut on thefront end of each bolt for securing said bolt head, saddle and swiveling block together and fixing them on the supporting head. j

3. In combination, a supporting head, a pair of bolt heads carried by the supporting head and movable lengthwise of or removable therefrom, a bolt extending forward from each bolt head, a saddle in front of each bolt head', adjusting screws extending horizontally through each saddle, a connection between the meeting ends ofthe adjusting screws, a swiveling block in front of each saddle through which the associated bolt extends, a clapper box mounted on an extension to each swiveling block, a hori---loV zontal pin passing through each clapper box securing the parts together, substantially as and extension, said pins both being located described. above the middle of the clapper boxes and In testimony whereof I aiix my signature.

With one pin located adjacent the rear face HENRY E. MORTON. of a clapper box and the other adjacent the Witnesses:

front face of the other clapper box, and a F. R. JEssoN,

nut on the forward end of each bolt for HARRY A. MORRIS.
