TRAVELING-HEAD SHAPER.

Specification of Letters Patent.

Patented Jan. 11, rain.

Application filed July 6, 1914. Serial No. 849,238.

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, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Traveling-Head Shapers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in traveling head shapers or planers and more particularly to that class of shapers which are designedfor heavy work and embody reciprocable tool carrying rams.

' The object of the invention is to make such machines applicable to other kinds of work without complicating their construction or affecting their operation as shapers, and to provide an attachment adapted to be readily fixed to the ram to be carried thereby and driven independently of the movements of the ram or traveling head.

lVith these and other ends in view the invention consists in providing the ram of a shaper with an arbor for transmitting motion to the extended end thereof and mounting upon said end an attachment which may be quickly applied thereto or detached therefrom to be driven by said arbor, said attachment embodying certain new and useful features in its construction, all as herein after more fully described and illustrated in the accompanying drawing, in which Figure 1 is an end elevation of a traveling head shaper showing the same as provided with a reciprocable ram and rotary cutter or planer applied thereto embodying the invention; Fig. 2 is an enlarged sectional detail of the ram and cutter attachment; Fig. 3 is a transverse section of the ram showing the attachment in elevation, and Fig. 4 is a sectional detail showing a modified construction of cutter head.

In Fig. 1 of the drawings, the invention is shown as applied to a traveling head, draw-cut planer or shaper of the type shown in Patent No. 682,218, of September 10, 1901, issued to M. and H. E. Morton, especially adapted for heavy work such as cylinders and other large parts of locomotive and other engines. .and machinery; but it will be understood that it maybe. applied as well to any planer or shaper having a tool carrying ram, and I do not, therefore, limit myself to. the particular construction of shaper or planer shown. The machine shown in Fig. 1, is of the type known as a draw-cut shaper and comprises a suitable base or bed A upon which is mounted a traveling head B carrying a vertically movable apron C provided with a bearing for a longitudinally reciproeable ram 1. The mechanism for moving the head B, raising and lowering the apron C and reciprocating the ram, is not shown in detail, as it forms no part of this invention.

As clearly shown in Figs.2 and 3, the ram 1 is preferably rectangular in cross section and is formed hollow or with a longitudinal bore to. receive a tubular shaft or arbor 2 which extends therethrough and is provided at the free or forward end of the. ram with atapered seat 3 for the tapered shank or hub 4 of a pinion 5, said hub being provided with a key 6 to engage a key-way in the seat 3. The inner end of the hub is also formed with an axial screwthreaded socket to receive the screwthreaded end of a locking rod 7 which extends longitudinally through the arbor and is provided with a collar 8 near its rear end to engage a suitable sleeve 9 having screwthreaded engagement with the screwthreaded end of the bore of the arbor. A second collar 10 fixed on the rod 7 engages the outer end of the adjusting sleeve 9 and the projecting outer end of therod is formed to receive a wrench by means of whichit may be turned to engage its screwthreaded' opposite end with the hub of the gear 5.

The gear 5 is detachably secured to the arbor 2 to turn therewith and may be readily disengaged therefrom by means of the rod 7, said rod being held against longitudinal movement and adjusted longitudinally in the arbor by means of the adjusting sleeve 9 which turns freely upon the rod between the collars 8 and 10. After the hub 4 of the gear has been engaged with its tapered seat in the end of the arbor, the rod is run through the arbor and attached to the hub by turning the rod to engage 1ts screwthreaded end with the screwthreaded socket of the hub, the adjusting sleeve 9 being at the same time screwed into the rear end of the arbor. After the rod has been engaged with the hub of the gear, the sleeve is turned upon the rod in a direction to move it outwardly and thus exert a pull on the rod which will draw the hub into its seat and firmly lock the gear upon the end of the arbor. When it is desired to detach the gear, the sleeve 9 is turned to move the rod in an opposite direction and force the hub out of engagement with its .seat.

A suitable gear carriage or casing 11 is secured to the rear end of the ram 1, and within this casing is a large gear 12 keyed to the projecting end of the arbor 2. Motion is transmitted to this gear to turn the arbor, by means of a train of gears 13 which is driven by a pinion 1 1 in the casing mounted upon a driving shaft 15 adapted to slide longitudinally through hearings in the casing and having a longitudinal key or spline 16 for driving the pinion 14. Power is applied to turn the drive shaft in any suitable manner, not shown. and thus the arbor 2 is rotated bv the splined drive shaft which perm ts of a longitudinalreciprocation of the ram.

The rotary cutter or planer attachment for the ram comprises a suitable head or saddle 17 formed to fit'over the ram 1 near its forward end and is held firmly in place thereon by means of clamping bars 18 and bolts 19. The saddle is bored longitudinally through its enlarged portion at the upper side of the ram to form a suitable bearing for the stub shaft 20 of the rotary cutter which consists of a disk 21 formed integral with the forward end of the stub shaft and is provided with a series of notches in its periphery to receive cutting tools held in place by means of clamping bars 23 and bolts 24:. The forward face of the disk 21 is a plane surface but the rear side of the disk is cut away to provide an overhanging peripheral flange 25 which is formed with internal gear teeth 26 adapted to mesh with the teeth of the pinion 5. A circular flange 27 on the forward end of the saddle 17 fits into the recess in the back of the disk 21 and this flange is provided with a suitable facing 28 between it and the adjacent surface of the disk. The flange 27 thus forms a backing for the disk so that when heavy pressure and strain is applied to the disk at one edge thereof in operation, the disk will be firmly held against tilting or springing and binding of its shaft 20 in its bearing will be avoided. -i i To prevent the projecting end of the ram which carries the rotary cutter from spring ing or getting out of alinement, a suitable bracket 29 is bolted to an adjacent part of the supporting frame work of the machine, such as a face plate (not shown) carried by the apron G, and this bracket extends outwardly and over the saddle 17 where it is formed with a suitable groove to receive an upwardly projecting rib 30 on the saddle and is made fast thereto by bolts 81 passing through slots 32 in the head of the bracket and engaging screwthreaded openings in the saddle. The outer end of the arm is thus rigidly supported by the bracket which permits of the adjustment of the rotary cutter to the workby loosening the bolts 31 so that the arm may be projected slightly to carry the cutter toward the work. As the bracket and arm are carried by the traveling head B of the shaper, the cutter may be moved past the work with a continuous feed by means of the mechanism (not shown) which is provided for reciprocating the head along the bed A of the machine. The cutter may also be raised and lowered with a continuous feeding movement by the mechanism (not shown) for actuating the apron C with a feeding movement.

As shown in Fig. 1, a" suitable work supporting table 33 is provided for supporting work 34 in position to be operated upon by the rotary cutter, and in Fig. l means is shown for supporting one end of a boring bar and driving the same so that'such a tool may also be used upon this class of machines to do certain kinds of work without the necessity for resetting the work after the shaping, planing or other operations have been completed, or where the work is so large that it cannot be readily done on other machines. The boring bar holder comprises a socket member 85 which is bolted or otherwise secured to the front face of the disk 21 and is formed with a tapered bore to receive the tapered end of a suitable boring bar 36. The bar is held in the socket by means of a suitable wedge key 37 engaging slots in the sides of the socket and an opening in the bar.

The cutting operation of the rotary cutter is performed at the advance side of the cutter in the direction of its feeding movement and to prevent the engagement of the cutters with the work at the rear edge of the cutter, it is necessary to tilt the saddle slightly upon the ram so that the axis of the stub shaft 20 will extend at a slight angle to the axis of the arbor 2. This adjustment of the saddle is secured by means of set screws 38 extending through one leg of the saddle at one side of the arm into engagement with a gib 39 resting against the side of the arm, suitable shims (not shown) being placed between the other .leg of the saddle and the opposite side of the ram. Set screws 10 are also provided on the bracket 29 to engage a gib 41 lying against the side of the rib 30 on the saddle for the same purpose.

By providing a hollow ram'with an arbor extending therethrough, suitable cutting tools ofvariousforms may be applied to the end of the ram and driven by'means of the arbor, thus adapting the shaper of the class shown to various forms of work other than draw-cut shaping. The particular construction and arrangement of rotary planing attachment gives a very powerful rotary planer Which may be quickly adjusted and attached and is adapted for use in planing various forms of heavy machinery, the work 34 illustrated in Fig. 1 being a number of eccentric straps for locomotives which are being faced off by means of the rotary planer as applied to the ram of the draw-cut shaper.

Obviously changes may be made in the details of construction without departing from the spirit of my invention, and I do not therefore limit myself to the particular construction shown.
