To tl/f who/1t it may con/cern:

Be it known that we, MATTHEW MORTON and HENRY E. MoRToN, citizens of the is a 'view of the gage in side elevation.

United States, residing at Muskegon, county of Muskegon, State of Michigan, have invented a certain new and useful Improvement in a Shaper for Crowning and Finishing Driving-Boxes on Locomotives and other Work, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

Our invention is designed to provide a shaper or planer adapted for various kinds of work, the same being particularly fitted, for example., for crowning and `finishing the driving-boxes on locomotives, including the planing of the exterior surfaces of said boxes. Our invention contemplates, however, any and all uses to which our improved apparatus may be applied.

`Our invention consists of the construction, combination, and arrangement of devices and appliances hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a view in perspective, illustrating features of our invention. Fig. 2 is a plan view showing certain portions of the machine for rotating the arbor which holds the cutting-tool.

Fig. 23 is a view of a shaper in side elevation to which our invention is applied. Fig. 24 is a view in section on the line 24 24, Fig. 2. l

Our invention is an improvement upon mechanism of this class for which a patent was granted to Matthew Morton, April 5 1892, No. 472,061, and Matthew Morton and Henry E. Morton November 1Q, 1895, No. 550,004.

lt is well understood that since the adoption of 'the large locomotives now in use and 'the heavy duty which they are called to perform resort has necessarily been made to steel driving-boxes, which are very hard to machine by any of the old methods heretofore employed. Hitherto analogous work has been accomplished by means of slottingmachines; but our apparatus is designed to provide mechanism forfmishing steel drivingboxes in a superior, economical, and simple manner.

Our improved apparatus is particularly adapted for use in repair-shops, as well as in the building of the driving-boxes.

Ve carry ouV our invention as follows: As applied to a driving-box, shaper, or planer, as shown in the accompanying drawings, a represents a supporting base or column. ol' a suitable shaper, to which and in which the gearing, shafting, feeding, and other mechanisms are applied. The upper portion of the base or column is slotted, as shown, -to receive a ram l), said ram having a toothed portion on its under side, as shown, engaged by corresponding gearing in said column, as hereinafter described. By the use of suitable mechanism, as hereinafter specified, the ram is made to reciprocate. Attached to the rear end of the ram is an adjustable bracket or frame c, on which is suitably attached a worm-pinion d. Passing through the ram is a hollow rotatable arbor c. The front endof IOO the arbor is recessed or bored tapering, as

shown more particularly in Fig. 6, and upon the rear end is movably attached a wormwheel o, keyed to the arbor and made adjustable longitudinally of the arbor. The rear end of the arbor is threaded and pro- IIO . ose of revolvin@` the bolt t uit-klv. P s

ljects sufficient to receive the compensating nut The nut f is constructed with a shoulder h. A collar-bolt i, passes through the arbor and through the nut Located 011 the arbor is a collar j and nut g, and upon the outer end of the bolt i is located a nut le. By turning the nut f the bolt i may be forced in either direction and held in given position by means of the nut 7c. The bolt 'i is squared or similarly constructed at the rear end thereof, as shown, to receive a crank for the pur- '.lhe opposite end of said. bolt is threaded to engage a rotatable head Z, constructed with a tapered end fitted and feather-keyed into the taper bore in the arimr e. The tapered end of the head is Itapped to engage the threaded end of the bolt It Will be seen that When the bolt is turned said head will he drawn to its proper position. Then by turning the nutfthe head Will be firmly held in position. Vhen it is desired to remove the head, it is only necessary to turn Vthe nut .f in Ythe proper direction. The rotatz'tble head lis constructed to receive a suitable tool-holder m, constructed to receive and hold in position various tools n.. Vile prefer to hold the toolholder or clapper-box m in position by moans of a pin p, the holder revolving upon pin, so as to relieve the cutting-tool on the return stroke of the ram. A. supplementary toolholder g is also preferably employed in the clapper-box,provided with a slot r, in which the (,:utting-tool is engaged. AThe cutting-tools and holder g are secured position by set-screws .S- in the clapper-box.

On the end of the head Z is a round and extended portion t, turned true and located `centrally with the body of the rotating head.

Movably attached to said portion is a gripecollar u, having a depending arm o of desired length. Said arm is provided with a suitable measuring-scale, as shown more particularly in Figs. 19 and 20 at w. Movably attached to said. arm t isa bracket a', being engaged upon a sleeve y by screws z, by loosening which the sleeve may be adjusted vertically upon the arm e. The bracket a: extends at right angles to the arm t' a sufficient distance to reach in under the cuttingtool n. The end of the bracket is provided with a micrometer-screw (indicated by the numeral adjustable in said bracket and by means of which the cutting-tool in ay be set at any desired. point or distance from the center of the head Z and by means of which the tool may readily be set any number of times alike. The arbor e is made to rotate by means of the Worm-Wheel o and gear d, the Worin-gear d being gearedwvith a shaft 31, as indicated at 32. The shaft of the Worm-gear is indicated at 33. The shaft 31 extends parallel With the arbor to the front of the machine.

The shaft 31 is a splined shaft. A ratchet feeding-gear 34, constructed with an internally-toothed ring 35, attached thereto, vrevolves a shaft 36, provided With a gearv 37, meshing with a gear 3S upon the shaft 31 to rotate said shaft. The ratchet feeding-gear is actuated in a manner to be described by a rack-bar 39. Attached to the shaft 36 is a hub 40, filling the bore of the ring, said hub provided with an opening 41 in the side thereof. A pin 42 passes through this opening, upon which is attached a double paWl 43, which is adjustably held in position by a spring 44. When the ratchet-gear 34 revolves .in one direction, the gear drives the .hub 4() and the payvl and causes the shaft 36 to make a partial revolution. ratchet-gear revolves in the opposite direction, the pawl passes over the teeth of the ring, the shaft not turning. The pawl may be turned to engage at either end thereof with the ring to turn the ratchet-gear in the opposite direction. rThe pawl may readily be manipulated by a lever 45 and may obviously be turned so that neither end will engage the toothed ring, in consequence of which the shaft 3l Will not be rotated. The rack is reciprocated in any suitable manner, as by a friction-feed common to all planers and embodied in Letters Patent granted to us November 19, 1895, No. 550,004.

The bevelgears 32 are carried by the ram, one of said gears being in sliding engagement with the splined shaft 31. As the rani reciprocates, the arbor e, it will be evident, will be made to rotate intermittently. The machine is thus enabled to plane any portion of a true circle and is particularly adapted for crowning driving-boxes.

A driving-box to be shaped is indicated at 46. Movably attached to the front side of the column a is a cross-rail 47, to Which is movably attached a saddle or apron 48 and a knee or bracket 49. The crossrail also carries a screw 50 for feeding the apron horizontally in the manner fully described in said Patent No. 550,004. The knee or bracket 49 is provided With an angular side 52 and with a plate 53, bolted to the lower edge thereof. A plate 54 is movably attached to said bracket, said platebeing planed off on a taper each Way from a given point, as indicated at 55 and 56, on the contact side. A center bolt 57 passes through the point indicated at 58, .from Which the plate is tapered. In Figs. 14 and 15 the taper is shown. slightly exaggerated for greater clearness. Three slots are shown planed through the plate (indicated at 59, 60, and 61) of sufficient depth to receive parallel strips, (indicated at 62, 63, and 64.) When said strips are in position, the front side of the plate will be in perfect alinement With the rain. The object of this construction is so that after a parallel cut has been taken said strips may be removed, and by tighten- When the IOO IIC

direction.

ing the inner bolt the plate may be ,drawn around to relieve a portion of the surface tapering, and so t-hat by loosening the inner bolt 6.5 and tightening the outer bolt 66 the plate may be placed at an `angle to relieve a portion .of the surface tapering in an `opposite of the sides tapering is to permit the box in passing around a curve to swivel slightly in the jaws of the locomotive-frame.

, As described in -said Patent No. 550,004, the main .driving-shaft, as indicated at 67, is provided with a pinion 68, meshing with a gear 69 `upon a-shaft 70, provided with a pinion 71, meshing with a gear 72 upon a shaft 73, provided with double pinions 7 4, meshing ,with the ram l). A gear 7.5 upon a shaft 7 Gineshes with the ram also. The shaft 76 is provided with suitable tappet mechanism 77 lto move the belt-shifter. The shaft 70 is provided with an additional pinion 7 S, meshing with the gear 79, which drives the feed mechanism, all as fully set forth in said Patent No. .550,004.

The bracket 49 is strengthened for supe porting heavy weights by an adjustable veri tical Ibearing 80, provided with a roller I81 at its lower end. .This roller operates upon a removable rail S2, bolted to the base of the machine. .only used when heavy weights are to be supported or machined.

Our improved machine is preferably provided with a crane comprising a mast S3, journaled in any suitable manner upon the machine, said mast arranged in such a manj ner that it may revolve in a full circle. Attached to the upper end of the mast is a casting S4, carrying the jib-arms S5, on which a trolley (not shown) may roll, thereby rendering the machine independent of other cranes or similar appliances.

The holders q may beislotted, as at r, on an acute angle lengthwise thereof to hold a cutting-tool. The holders may be made to hold cutting-tools to cut to the right or to the left, as indicated more particularly in Figs. 9 and 10. It will be seen that the cutting-tool may thus be rotated circumferentially, together with the head. these holders in the clapper-box for use with a side-cutting tool it will readily be seen that the tool will relieve on the side cut, also in forming out the corners of driving-boxes.

Upon the feed-rod 31 is a worm-wheel 86, loosely mounted upon the rod. A handwheel 87 is provided with a hub 8S, engaged upon the end of the rod, the hand-wheel and its hub being arranged to be tightened up against the worm-wheel to rigidly engage the worm-wheel in place, so that when the wormwheel is rotated the rod 31 will be turned thereby. A worm-pinion 89 has its shaft provided with an operating handle or crank 90, by turning which the rod 31 may be masaaie@ The object of relieving a portion.

The strengthening mechanism is 4 By placing one ofl nipulated. Said rod is geared, .as already described, with the shaft .of the -wormfwheel d, whereby the cutter may be Vfed to the .work .or backed away from the work by .operating the worm-gear S6. The rod 31 is preferably provided with a link :91, -jointedly interposed therein to permit the eleva-tion and lowering .of the front end of the feed-rod, as may be desired. A back bearing for the chuck that holds the work is indicated at The chuck for hold-ing a driving-box upon the shaper to finish the interior of the box is in dicated in Figs. 1, 2, 18, and 22 and comprises, essentially, a base-plate 9.3, attachable to the knee-bracket 49 of the machine, supporting thereupon cheek-plates 94 and 95, made adjustable upon .the base-plate y93. A crosspiece 96 is .adjustabl-y engaged upon the top of the cheekfpieces, so as to hold the work rigidly in planing the same in every direction. The cheek-pieces are provided with clamp.- ing devices -97 to clamp upon the work. For planing the side .of the box to fit `.the jaws ,of the frame `of -the locomotive the holder ,consists, as already described, .of the plate v54, arranged as hereinbefore set forth, and `clanip's 98, secured upon the .work by the bolts 57, 6.5, and 66. It will be understood that the pla- tes 54 and 93 are not used lat the same time.

The feeding mechanism is described in our Patent No. 550,004 and embodies a releasing device 107, a triangular' bell-crank arn^99, fulcrumed at l100 and having formed therein vat one extremity a slot 1101, `in which .reciprocates a wrist-pin 102, carried in a customary manner upon a rotatable friction .device Adjacent ythereto we locate a lever 103, fulcrumed, as at 1,04, and provided at its inner end with the pin 104 yand pins 10,5 and 1:06. The lever may be set and heldin various po- `sitions by a spring-bolt (indicated at 10.7)

engaging the side of ythe Shaper. By adjusting the lever the -releasing Vdevice 140.8 may strike one of the points 104 105 106, so that three changes of feed are thus provided for in a very simple manner.

The operation of our improved mechanism will now be understood.
