Specification of Letters Patent.

Patented Get. 16, 1917.

Application filed May 7, 1917. Serial No. 167,133.

I '0 all whom it may concern:

Be it known that we, TVVALTER T. KRAUSC'I-I and Emvsr F. IVEBER, citizens of the United States, and residents of La Grange, in the county of Cook and State of Illinois, and of Chicago, in the county of Cook and State of Illinois, respectively, have invented certain new and useful Improvements in Tie- Sawing Cars, of which the following is a description, reference being had to the accompanying drawings, which form a part of our specification.

Our invention relates to a car that is especially adapted to move or run on rails (laid on the ties to be saved) by means of its own motive power, which power is also adapted to operate the sawing mechanism; the sawing mechanism being adjustably mounted on the car so as to permit it to be swung into and out of operative position.

The invention contemplates a construction whereby both ends of the ties may be simultaneously cut to the desired depth and on opposite sides of the rails, in order-that the portions intermediate of the cuts may be subsequently removed with a suitable adz and thus enable the placing of suitable tieplates beneath the rails. The construction enables the ties to be cut to any desired depth and in a uniform manner, while at the same time permitting the cut portions to be quickly removed so that the operation,

of tie-cutting or adzing may be accomplished in materially less time than has been the case where this operation is entirely manually performed'by the use of an adz. The construction and its advantages will be more fully understood and comprehended from the following detailed description of the accompanying drawings, wherein Figure l is a side elevation. Fig. 2 is an end elevation thereof,. with portions shown in section. V Fig. 3 is a detail sectionalview, taken on the line 3-3 of Fig. 1, looking in the direction of the arrows.

In the particular exemplification of the.

I it comprises a suitable frame 10, shown preferably composed of channel JIOI] and constituting the side sills. which'are seinvention.

cured togetherby suitable cross-sills shown.

at 11 in dotted lines in Fig. l; the underframe or longitudinal sills being provided with suitable hangers or journal boxes for the ,ieurnals of the wheels 12,- Whieh latter are adapted to run on the rails 13 of the road-way.

The underframe is provided with a suitable fioor indicated at 14 in Fig. 2. The car is also provided with an internal combustion motor, indicated at 15 in Fig. 1, of any suitable construction and capacity; the motor being supported by suitable framework, as indicated at 16. 'As the motor forms no part of our invention, a specific description thereof will not be entered into.

The longitudinal members 10 of the underframe are provided with suitable pillows or bearing blocks 17 which provide bearing for a transversely disposed shaft 18 to which is secured a sprocket-wheel 19 which receives the sprocket chain 20. The chain 20, in turn, is driven ofl of the power or driving-shaft 21 of the motor, see Fig. 1. The counter-shaft 18 is also provided with gears 22 and 23 that are secured thereto so as to rotate with the shaft. The gear 23 is adapted to mesh with gear 24 which is adapted to idle on an independent axis and also to mesh with a gear 25 which is feathered or slidably keyed on ashaft 26 by means of the key 27 so that gear 25 may be moved lengthwise of shaft 26 into and out ofoperative relation with the idler 24.

The shaft 26, which is rotatably mounted in suitable hangers 28 secured to the underside of the longitudinal sills, also has a gear 29 feathered orslidably mounted on shaft 26 sons to be moved into and out of operative relation with the gear 22 of shaft 18. In the particular exemplification of the invention, the two gears 25 and 29 are shown secured to a sleeve 30 which is slidably keyed or feathered on the shaft 26 so that both gears 25 and 29 may be controlled by a single shifting element. For this purpose the sleeve 30'is provided with a circumferential groove 31 adapted to receive the in wardly presented trunnions or ends ofthe lowerbifurcated end of a shifting lever 32, which is pivoted at 33 in a suitable manner on the floor or underframe 'of the car, see Fig. 3.. As is apparent from the construction shown, with the gear 29 in mesh with gear 22, power 1s transmitted to the counter shaft 26 in a given direction. while a slight shifting of lever 32 will move gear 29, into neutral or inoperative position before gear 25 has been moved into operative relation" with the idler 24!. Further oscillation or diameter than 34) and-cause movement of lever 32 to the left in Fig. 3 will shift the coupled gears 29 so as to cause gear 25 to mesh with idler 24L and thus'transmit power to counter-shaft 26 in the reverse direction. I

The shaft 26 is provided with a pair of sprocket wheels 34; and 35 which are preferably loosely mounted on the shaft, but held against movement lengthwise of "he shaft. The hubs of both sprockets are provided with suitable clutch-engaging surfaces, as shown in Fig. 3, adapted to effect clutching engagement with a clutch later described. The sprocket-wheel 3 f receives a sprocketchain 36 which takes about the large sprocket-wheel 37, shown in dotted lines in Fig. 1, and which is either secured to the journal 38' or to the hub of-the wheel 12'; while the sprocket wheel 35 receives a sprocket chain'- 40 which takes about sprocket wheel-41, which, like sprocket wheel may either besecured to the journal 38 or to'an extended portion of the hub of the wheel.

Slidably keyed on shaft 26, intermediate ofthe sprockets 34: and 35', is a clutch 42' which is-adapted to have clutching engagement withboth sprockets and'35 so as to transmit: power from shaft 26 to either one of the sprockets when the clutch has been shifted in the proper direction. The clutch i2; is operated by aleverf3 fulcr-u-med at 4st in a suitable manner to the floor or underframe so" as to shift or oscillate a direction transversely of the car and therefore longitudinally of shaft '26.

With -the lever 43 in the position shownin Fig. 3, the clutchl2 is'in neutral or inopera tiveposition, so that power will notice transmitted' from driven shaft 26 to the car ourna'l-oraxle 38 while a shiftingoroscillation ofl'ever 4:3 to the right in 3 the clutch 26,- into operative relation with wheel 3e and thereby cause the car ata given speed forward. On the other hand, if lever 43 is shifted to the left in Fig; 3-, clutchdQ will then be moved into operative relation with sprocket whee (which, in the enempliiica-tionr shown of larger the car to be moved forwardly at a greater speed.

'The forward end of the car-frame, ata point forward erafbly made with the upwardly bent or in clining portion 10, zontally presented portiom so as to provide a support or bearing for. the pivotal point sprocket of the cutting mechanismat a suitable point above the/floordevel of the can 1n, order to permit proper movement of the cutting mechanism which. will now he described.

Thei twoside frame-members are cash provided with. suitable hearings or blocks &5,-4 5, i-n w-hi-cha shaft 453 isjournaled', the

shaft 46 -'extending transversely-of the ear 'rotatably mounted a shaft 56.

will move d2, which is feathered on shaft to travel of the front journal, is prefterminating in a horn or machine, as shown in; Fig. 3. The shaft 4:6 is provided with a pulley 4:7 secured thereto so as to rotate therewith; the pulley 4.?- being adapted to receive a belt 4:3 which takes about a pulley l9 secured on the power or driving shaft 21 of the motor. The shaft l'tfis also provided with a sprocket wheel 50, loosely mounted on the shaft it and arranged to be controlled by a suitable clutch 51 feathered on shaft re and adapted to be operated by a lever hlovement oflever 52 either to the right or. to the left will move the clutch into and out of operative relation withthe sprocket wheel 50.

The shaft 46 is also provided with a vertically disposed and swinging frame 53, preferably composed of the two side members, as shown in Fig; 1, which are suitably braced and secured together by the transverse members 5% so as to provide the rec tangular frame shown in Fig. 2, which is adapted to swing vertically about the shaft 46. I

The upper end of the frame is provided with suitable bearings at 55 in which is v Secured to shaft 56 so as to rotate therewith. is a sprocket-wheel 57 which is adapted to re ceive a sprocket-chain 58 which takes about and meshes with sprocket wheel 50, so that ower will be transmitted from shaft as to shaft 56 when clutch 51 has been moved into clutching engagement with sprocket Mounted on shaft 56, so as to rotate therewith, is a pulley-wheel 59, receiving a belt 60 which passes about a pulley. 61' secured. to a shaft 62 rotatably mounted in suitable hangers 63 at the lower ends of the vertically disposed frame members As more clearly shown in- Fig. 2, the'bearings or hangers 63 are preferably removably secured at thelower ends of the frame members 53 by means of the bolts 6%. r

The fra1n .e-members 53am of such length as enables them'to .dependbelow the car-floor to 'a point into proximity with the rails. on which; the car operates. The angle ofinclination from the perpendicular of the frame53 is controlled by means of a rod 65 which is preferably pivoted at 6.6v to a portion of the carunder frame, vsee Fig. 1., so as to permit-the rod to swing in a vertical direction and extendisomewhat. forward of the vertical plane. of the pivotal point of frame 53,.namely into a vertical plane forward of the shaft 46. One of the cross members 5% of. the vertically swinging frame is provided with a split'clamp member 67, see Fig. 2, pivotedat 68 and adapted to permitthe' rod 65 to extend therethrough; the split ends of the clamp-member 67 be ingprovided with a screw bolt receiving the -:handle or butterfly nut 69- whereby the: split ends of the. clamp-member 67 may be drawntogether into .firm clamping' engagement with the rod after the frame has been swung into the desired inclination.

Both ends of shaft 62, which extendbe yond the bearings 63, are each provided with sleeves keyed to the shaft so as to rotate therewith; and the opposite ends of both sleeves are arranged to receive the circular saws 71, '71, which are firmly clamped in place by suitable nuts and washers, indicated at 72, so as to compel the saws to r0- tate with the sleeves and therefore with the shaft 62.

The shaft 62 has adjustable relation with the frame members 53, because the latter are provided with slots, as shown at 73 in Fig. 2, through which the bolts 64; pass.

1 The saws are preferably provided with the segmental guards 74, disposed over the top of the saws; the guards being preferably of sheet metal and supported by the arms 75 secured to opposite sides of the guards and somewhat radially disposed, as

shown in Fig. 1, with the inner ends of the,

arms 75 bearing against the sides of the lower ends of the frame-member 53.

In order that the belt 60, whereby power is transmitted from shaft 56 to shaft 62, may be maintained under proper'tension, we provide the set-screws 76 which engage with the upper ends of the arms of bearing members or hangers 63. As the hangers 63 have adjustable relation with the frame 53, by means of slots and bolts 73, 64, the setscrews 76 may be turned so as to force the hangers downwardly and therefore also cause shaft 62 to move downwardly, which will place the belt 60 under tension; the set-screws 76 preventing the hangers 63 and shaft 62 from being moved upwardly through the action of the belt.

As is evident from the construction shown and described, the cutting mechanism can be swung vertically out of operative position, while the car is transported from place to place until the point is reached where the ties are to be cut or sawed, when the lower end of the frame of the sawing mechanism is swung downwardly, which is accomplished by releasing the clamping nut 69 of the clamping member 67 so that the latter may slide along rod After the frame has been swung downwardly to the point where the saws 71 will produce a cut in the tie indicated at 77 in Fig. 2, to the desired depth, the clamp-nut 69 is screwed up so as to cause the clamping member 67 to have firm gripping relation with rod 65 and thereby lock the swinging frame in its adj usted position.

'.lhe motor being in operation, power is transmitted to shaft 526 through the medium of belt 48 and pulley 47 the lever 52 is then oscillated so as to throw clutch mechanism 51 into clutching engagement with the sprocket-wheel 50, thereby causing power to be transmitted to shaft 56 in the upper part of the swinging frame and this, in turn will transmit power to the saw-holding shaft 62 by means of pulley 59, belt 60 and pulley 61. The swinging frame having been adjusted to provide a cut of desired depth'in theties, the car may travel along the rails at a suitable speed, controlled through the operation of clutclroperating lever 43; while the direction of travel is de termined by the gear-shifting lever 32.

It is apparent that one or two operators can perform the operation of tie-cutting, one operator preferably controls the move ments of the car, relative to the roadbed or track, while the other is preferably in charge of the operation of the sawing or cutting mechanism; or a single operator might be employed. The device enables a considerable number of ties to be quickly cut or sawed to the desired depth and with a uniform out, while the sawed portions of the tie may be readily removed with a suit able adz in the hands of an operator or operators, who follow up the sawing car. Our improved car enables these operations to be accomplished in a very much less time and with greater accuracy than has been the case where the portions of the ties have been entirely removed manually by the use of an adz; while at the same time our construction provides cut-out portions of uniform depth throughout, so that the tie-plate may not only be disposed, throughout its length, in substantially the same horizontal plane, but will also be flush with the tie and have bearing on the tie throughout its entire lower surface;

By providing a vertically swinging frame, as shown in the drawings, wherein a portion of the frame extends to a considerable distance above the pivotal point or shaft 46, with the upper end provided with a large pulley, power is not only transmitted to the saws so as to have the latter rotate at a suiiicient speed, but a counter-balanced swinging frame is provided which enables easy manipulation or adjustment of the frame into the desired positions.

e have illustrated in the drawings and described in the foregoing specification what we believe to be the simplest and best adaptation of the invention, but it may have expression in somewhat different mechanical form without, however, spirit of our invention.
