HENRY IE. MORTON, OF MUSKEGON HEIGHTS, MICHIGAN.

DRAW-CUT SI-IAIPER-HEAD.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed October 11, 1915. Serial No. 55,224.

To all whom it may concern:

Be it known that I, HENRY E. MORTON, 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 Draw-Cut Shaper-Heads; and I do hereby declare the following 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 head adapted to be attached to draw out shapers, metal planers and like tools in which a cutting toolis drawn back and forth over the work acted upon or the work is moved back and forth with respect to the cutting tool.

It is the object and purpose of my invention to provide atool of this character capable of a wide range of adjustment and also of fine adjustment and one comprising many new and useful features of construction and operation which will be apparent upon understanding of the embodiment shown in the accompanying drawings, in which;

Figure 1 is a side elevation of a draw out shape-r having my invention applied thereto. Fig. 2 is a similar side elevation of the head. Fig. 3 is a front elevation of the head. Fig. 4 is a plan view thereof; and Fig. 5 is a detail of an element used in positioning the cutting tool in the head.

Like reference characters refer to like parts throughout the several views of the drawings.

The frame of the shaper is indicated at 1 in front of which is the bed 2 upon which the work is held, the bed being adjusted vertically by any suitable adjusting means indicated at 3 and steadied after adjustment by a suitable support at at the front end of the bed. The ram 5 of the shaper is mounted adjacent the upper end of the frame 1 and may be drawn back and forth over the table by any suitable mechanism which, as it forms no part of the present invention, is not shown or described.

On the front end of the ram 5 a supporting head 6 is'located being screw threaded on to the ram and held in position by means of set screws 7 which pass through the supporting head and against any suitable binding block or plug located between the screws and the end of the ram. The supporting head is positioned substantially horizontal and has in its front face a T- slot 8 adapted to receive the bolt head 9 which is of a shape to fit within the wider portion of the slot and project slightly forward into the narrower portion. In the present construction the tool includes two tool supports or clapper boxes as they are known, which are carried by individual bolt heads 9 so that there are two of the bolt heads located in the T-slot 8. In front of each bolt head is located a saddle 10 and through each saddle passes an adjusting screw 11. The ends of the adjusting screws in the two blocks meet each other and one is provided with a screw threaded socket and the other with a reduced and screw threaded end which fits into the socket as indicated at 12in Fig. 3. Each saddle has an upper projection 13 on which is hung a swiveling block 1 1, at its upper end having. a curved slot 15 through which a bolt 16projects from the extension 13 of the saddle.

On the forward extension 14: of the swiveling block the tool support or clapper box 17 is located and is adapted to carry the cutting tool 18, slots 18 being provided on both sides of the tool support so that a cutting tool may be positioned on either or both sides of the tool support as indicated in Fig. 3. The cutting tool is held in position by means of set screws 19. In front of each tool support is located a plate 20 attached by means of a screw connection to the tool support and serving as a bearing plate for the nut 21 which threads on to the end of the bolt 22 passing through the'tool support, saddle, swiveling block and bolt head as indicated in dotted lines in Figs. 1 and 2 in this manner securing the parts together. Each tool support has also a. slight pivotal movement on the forward extension 14 of the swiveling block, a substantially horizontal pin 23 passing through the tool support and its associated extension 14:. It is of course apparent that on the back or working stroke of the ram the tool support, when it bears against the nut 21, is held in absolutely rigid relation to the extension 1 1 and that it is only on the forward stroke of the ram during which no operation upon the work takes place that the tool support is permitted to swing slightly about its pivot pin 23.

With a tool holding head of this character applied to the ram of a draw shaper or attached to a metal planer it is evident that many new and useful operations may be performed. For instance. it is possible to place a cutting tool in one tool holder and locate it so that it will take the first or roughened cut from the work and follow it up by another tool, in the other tool holder which will take the finishing cut, it being understood that in machines like draw out shapers, planes and the like, the work and tool move laterally with respect to each other with each reciprocation of the tool lengthwise of the work. Further more, by reason of the pivotal attachment of the tool holder to the forward extension 14* of the swiveling block, on the forward stroke of the ram the tool does not bear against the work but moves over it without injury thereto. It is also possible by loosening th nut 2l to adjust the tools any suitable or desired distance apart and this adjustment may be made as fine as desired by operating the adjusting screws 11. The tool holder may also be turned about the bolt 22 as a pivot, slots 15 permitting a limited range of angular adjustment. Also each tool holder may be adjusted to a slight angle with respect to the vertical and each tool holder is independently adjustable. Furthermore by having the slots receiving the tools on either the inner or outer sides of the tool holder a great range of adjustment is possible. It is also possible, by attaching to the tool 18 a channel like loop 24% fixing it in place by'means of the set screw 25, to remove the tool at any time for sharpening and to replaceit in exactly .the same position that it occupied before removal. Furthermore as indicated in Fig. 8 this head for draw out shaper, planers and the like permits the use of cutting tools on irregular shapes and especially in grooves, both sides of the groove being finished at the same time. Various other advantages not specifically enumerated will appear to those skilled in the art due to my invention.

Changes in minor details of construction may be resorted to without departing from my invention which is defined in the appended claims, the invention including all modifications in structure falling within their scope.

I claim V 1. In combination, a supporting head having a T-slot in a face thereof, a pair of bolt heads positioned in the slot, a saddle in front of each bolt head, a swiveling block located in front of each saddle having a slot in its upper portion, a bolt passing from the saddle through the slot, a nut on the bolt, a tool holding support on the swiveling block and mounted on a horizontal pin extending through the block, said tool holder having a vertical groove in the side thereof adapted to receive a cutting tool, and a bolt extending through each bolt head, saddle, swiveling block and tool holder and provided with a nut at its forward end for securingsaid elements together in fixed relation to each other and the supporting head.
