JAMES C. STEEN, OF CINCINNATI, OHIO, ASSIGNOR TO THE CINCINNATI SHAPER COMPANY, OF CINCINNATI, OHIO, A CORPORATION SHAPING-MACHINE.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed May 31,1904. Serial No. 210,619.

To all whom it may concern:

Be it known that I, J AMES C. STEEN, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Shaping- Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of my specification.

My invention relates to shaping-machines,

and more particularly to a shaping-machine provided with a pull-cut head.

The object of my invention is to so construct and arrange the head and its connection with the ram that the pull of the tool when cutting is exerted against substantially square bearing-surfaces in the solid metal.

The advantages of my construction will appear as I proceed with my specification.

In the drawings, Figure 1 is a side elevation of the front end of a ram with my improved head attached thereto. Fig. 2 is a vertical section through the same. Fig. 3 is a front elevation of the head and ram. Fig. 4 is a partial plan and section of the ram on the line 4 4 of Fig. 3. Figs. 5 and 6 are details, which will be referred to later.

A is the body of the ram, which is provided at its forward end with a boss formed into an annular groove to and an annular shoulder 6. (See Figs. 2 and 4.) The forward end of the ram A is bored out to receive a trunnion B, which forms part of a flanged disk C, the rear face of the disk bearing against the end of the ramA and the flange of the same forming with the annular groove 0 an annular closed slot in which the one-sided heads of bolts D D fit, which by means of the nuts D clamp the flanged disk in any angular position. The flanged disk C is cut away at the bottom (see Fig. 2) to receive a key d, having flanges d d, which engage, respectively, the front face of the flanged disk and the shoulder b on the ram, thus conveying any pull on the disk directly to the ram, said key being retained in place by a screw d.

The disk C is provided at its forward end or face with vertically-extending ribs E E, provided with flanges or shoulders E E. These flanged ribs E E are embraced by the sides of a hollow box F, which is open at the back and provided with vertically-extending flanges or shoulders ff, which, together with justment of the tool-carrier.

the flanged ribs E E and the sides of the box F, form closed grooves in which fit wedges G, by means of which the box F may be'clamped in position. It is thus apparent that any pull on the forward face of the box F is borne by the flanges or shoulders E f and the wedges G. The rear face of the box Fis let into the front face of the ring C, spaces being left at each side to receive the gibs e 6, (see Figs. 3 and 4,) which are held in place by squareheaded screws 6. These serve to prevent any lateral play of the box.

The sliding box F is operated up and down for the down feed of the tool in the usual manner through the screw 9, the gears g g, the shaft it, and the gears h, as described in Letters Patent No. 656,795, of August 28, 1900, granted to Steen and Warner, and forms no part of this present invention. The operation is apparent from the drawings.

The tool-carrier J is supported on the sliding box F in the following manner: The sliding box F is provided with a boss H, which has at its lower side square shoulder H, forming an arc'of a circle extending through an angle of less than one hundred and eighty degrees. J is the tool-carrier and is secured against the face of the box F. The rear face of the toolcarrier is socketed to receive the boss H, the lower edge of the socket being provided with a-square shoulder H, engaging the shoulder H on the boss H. The shoulder H is also formed in the arc of a circle, but extends through an angle of about one hundred and eighty degrees. (See Figs. 2, 5, and 6.) The tool-carrier J is journaled on a screw-threaded pin K, which screws into the boss H, the axis of the journal being concentric with the center of the arcs in which the shoulders H.

and H are formed. It is apparent that the diflerence in angle of the arcs in which the shoulders H and H are formed will permit of the tool-carrier being slipped into or out of place by properly shifting it on the journal-pin K. It is not necessary that the angles of these arcs be as described, it being suflicient that the angles of the two when summed together shall be less than three hundred and sixty degrees. (see Figs. 2 and 3) permits of the angular ad- The tool-carrier is bifurcated at its forward end, and between the bifurcations J J is pivoted a toolholder M on the pin M.

A bolt and slot L and L It is apparent that with the pin M in the position shown the tool will cut on the return stroke.

From the construction described it will be seen that the pull of the tool is exerted directly on the shoulders H H", E, andf and b, the strain being thus exerted on solid metal throughout. I find that this construction is very strong and durable and prevents the necessity of taking up wear and tear by the lightening of bolts.

Having thus described my invention, what I desire to claim as new and cover by Letters Patent is 1. In a pull-cut shaping-machine, in combination with the ram and down-feed box, a boss on the front face of said box, a bifurcated tool-carrier havinga socket in its rear face to receive said boss, engaging shoulders forming arcs of circles at the edges of said boss and said socket, the sum of the two arcs being less than three hundred and sixty degrees, a pin centrally located as to said arcs secured to said boss and forminga journal for said toolcarrier, means for clamping said tool-carrier in any angular position, and a tool-holder pivoted at the forward ends of the bifurcations of said tool-carrier, substantially as described.

2. In a pull-cut shaping-machine, in combination, the ram, the down-feed box, a bifurcated tool-carrier rotatably supported with its rear face against the face of said down-feed box, a boss on the face of said down-feed box, a socket in the rear face of said tool-carrier to receive said boss, engaging shoulders forming arcs of circles at the edges ofsaid boss and said socket, the sum of the angles of said arcs being less than three hundred and sixty degrees, means for clamping said tool-carrier in position, and a tool-holder pivoted in the bifurcation of said tool-carrier, substantially as described.

3. In a pull-cut shaping-machine, in combination with the ram, a boss at the forward end of said ram formed into a radially-extending annular shoulder and an annular groove between said shoulder and the forward end of the min, a flanged disk journaled on the end of the ram, the flange of the same forming with the annular shoulder and groove in said boss a closed annular slot, bolts with their heads in this closed slot clamping said flanged disk to the ram, vertically-extending flanged ribs in the front face of said disk, the downfeed box embracing said flanged ribs, its sides being provided with flanges located behind the flanges on said ribs, wedges embraced between said flanged ribs and the flanged sides of said box, a boss on said down-feed box, a

bifurcated tool-carrier journaled on said boss, a socket in the rear face of said tool-carrier to receive said boss, engaging shoulders forming arcs of circles at the edges of said boss and said socket, the sum of the angles of the two arcs being less than three hundred and sixty degrees, means for clamping said toolcarrier in any angular position, and a toolholder pivoted in the bifurcations of said tool-carrier, substantially as described.

4. In a pull-cut'shaping-machine, in combinationwith the ram, a boss at the forward end of said ram, an annular groove in said boss, a flanged disk the flange of which together with said annular groove on said boss forms a closed annular slot, bolts with their heads in this closed slot clamping said disk to the ram, a key provided with flanges engaging the groove in the ram and the front face of said disk, the down-feed box provided with vertical shoulders engaging similar shoulders on said disk, wedges clamping these shoulders in position, a bifurcated tool-carrier rotatabl y.

supported with itsrear face against the face of said down-feed box, a boss on the'face of said down-feed box, a socket in the rear face of said tool-carrier to receive said boss, engaging shoulders forming arcs of circles at the edges of said boss and said socket, the sum of the angles of said arcs being less than three hundred and sixty degrees, means for clamping said tool-carrier in any angular position, and a tool-holder pivoted in the bifurcations of said tool-carrier, substantially as described.

5. In a pull-cut shaping-machine, in combination with the ram, a boss at the forward end of said ram formed into a radially-extending annular shoulder and an annular groove between saidshoulder and the forward end of the ram, a flanged disk journaled on the end of the ram, the flange of the same forming with the annular shoulder and groove in said boss a closed annular slot, bolts with their headsin this closed slot clamping said flanged disk to the ram, a key provided with flanges engaging the groove in the ram and the front face of said disk, vertically-extending flanged ribs in the front face of said disk, the downfeed box embracing said flanged ribs, its sides being provided with flanges located behind the flanges of said ribs, wedges embraced between said flanged ribs and the flanged sides of said box, and a tool-carrier and means for securing the same to said down-feed box, substantially as described.
