ALBERT OOLLET, OF PARIS, FRANCE.

MACHINE FOR CUTTING RAIL-SEATS IN RAILWAY-SLEEPERS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed January 27,1906. Serial No. 298,234-

To (bl [1 10/1/0171, it may concern.-

Be it known that I, ALBERT CoLLET, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Machines for Cutting Rail and Chair Seats in Railway-Ties, of which the following is a specification.

This invention relates to machines for cutting gains or recesses in wood; and its object is to provide a machine for cutting or routing out a recess or gain in the upper surface of a railway-tie to receive and form a seat for the rail or for a chair to receive and support the rar The machine may employ any kind of cut ting tool or tools suited to the purpose; but it is preferred to use toolsof the construction illustrated in my pending application, Serial No. 298,233, filed January 27, 1906.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side elevation of the machine. Fig. 2 is a front elevation of one-half of the machine, which latter is in practice double or adapted to cut at the same time the seats for both of the rails of a track. Fig. 3 is a sectional view illustrating the drivinggear of the cutter. Fig. 4 is a cross-section taken along the axis of the shaft H in Fig. 1 at the dotted line M M, but on a larger scale than Fig. 1. Fig. 5 is a plan of a part of the machine-carriage and of the parts for effecting the lateral movement of the cutter-shaft, the recess or gain being cut by two reciprocating operations of the cutting-tool. Fig. 6 is a cross-section at N N in Fig. 5. Fig. 7 is a side view of one of the spring catches or bolts. The details of this mechanism are best illustrated in Figs 8 to 11. Fig. 8 is a plan of the plates at the front of the machine-carriage. Fig. 9 is a section along the curved line O P Oin Fig. 8. Fig. 10 is a view similar to Fig. 6, but drawn to a much larger scale. Fig. 11 is a section at line B R in Fig. 8. Figs. 12, 13, and 14 are illustrative views. Fig. 12 shows the side of the sleeper or tie and the shape of the recess or gain cut in it. Fig. 13 is a plan of the cutting-tool. Fig. 14 is a plan of the sleeper or tie, the tool being shown in dotted lines as shifted over laterally.

The operation of recessing or cutting gains in the sleepers or ties will be carried out on any piece of trackas a siding, for example. In the drawings, R designates one of the track-rails of such a siding, and T designates a tie extending across said rails in position to be operated on.

It may be explained, primarily, that the recessing-machine (seen at the right in Fig. 1) consists really of two like machines connected by a transverse rod or bar P and each having a frame J and a carriage G slidable thereon. The cutters are actuated or driven from a motor W, (seen at the left in Fig. 1,) said motor being mounted on a carriage which runs on the track-rails of the siding, only one rail R of said track being herein shown. This may be an ordinary electric motor, of which F is its rotating drivingshaft. The tie T to be recessed does not rest on the track-rails R, but on supports which are adjustable, so that the tie may be raised or lowered in order that the gain cut in it shall be recessed to the proper or desired depth. The two cutting mechanisms will be so spaced or trammed that the gains or recesses cut simultaneously in the tie will be at exactly the proper distance apart. The frame J rests upon the track-rail R and has slotted cheeks or cheek-pieces K, which embrace the rail, the frame J being drawn down and held firmly in place by keys Z and l (seen clearly in Fig. 4) in the slots in the cheeks.

The upright cutter-shaft C, Fig. 3, rotates in an upright bearing D, integral with sleeves D, which embrace and clamp on rods E, which connect with the motor W. On the upjrer end of the shaft O is a bevel-pinion which gears with abevel pinion or wheel '5 on the forward end of the motor-shaft F. This mechanism provides the means for driving the cutter or cutters B in the head A on the shaft O. The upright bearing D is secured to the forward end of the carriage G by means of a sector U on and integral with a movable plate U, said sector having a collar which embraces and clamps the bearing D between two shoulders g g on the latter. The plate U turns about an upright in X, set firmly, Fig. 10, in a bed or plate U, on and integral with the carriage G. On the under side of this carrige G, Fig. 4, is a rack with which gears a pinion on a cross-shaft H, rotatively mounted in the frame J, and the said shaft may be rotated through the medium of a hand-wheel I, for moving the cutters forward and back across the tie to be recessed. It may be here noted that when the cutter-head is moved forward andback the engine W and the carriage Gr move with it,

chines, only one of which is herein shown.

The device shown consists of a lever L, fulcrumed at 0 on the frame and carrying at its ends a shoe n, upon which that end of the tie T is supported, At its rear end the lever L is forked and slotted to engage pins 2) on a nut 9, through which extends a screw 1'. This screw 1 is rotated in turning the lever about its fulcrum, by means of the device heretofore called the hand-wheel I. The boss of this wheel is fixed to a sliding sleeve, which incloses the bearing of the shaft H, and on this sleeve are two sets of teeth 8 and 8. When the sleeve is pushed in to the position seen in Fig. 4, the teeth 8 engage with similar teeth on a bevel-pinion t, rotatable on the bearing of the shaft H and gearing with a pinion t on the upper end of the before-mentioned screw 1*, Fig. 4.

It will be obvious how the tie T may be elevated to the desired height by the means described, and also lowered to the rails after the cutting or recessing operation. By sliding the sleeve back or outward until the teeth 8 are disengaged and the teeth 8 are caused to engage teeth carried by the shaftH the latter may be rotated, and through the medium of the pinion 7c, and rack the cutter-- carriage G be moved to and fro. When the tie T is raised, its upper surface bears on screw-stops u, the tips of which may be regulated as to height by screwing the screws up or down. These stops are carried by bent arms M on a transverse part N in the frame;

This transverse part forms an integral part or cross-head on a longitudinally-extending bar 0 in the frame J. This bar is seen in dotted lines in Fig. 1. The bridge-piece J of the frame J, Fig. 4, together with the bar P, serves to connect the two machines rigidly together, abreast on the track.

The cutting devices and the means for operating them will now be described, premising that the cutters or cutting-tools B are mounted in a head A, screwed onto the lower end of the upright shaft 0, and that means are provided whereby the cutter is made to out a wide gain by first advancing it across the tie T,- then shifting it laterally, and then drawing it back again across the tie.

' The construction will be best understood by reference to Figs. 5 to 14. The carriage G is provided at its upper part with a rod Q, coupled at one end to an arm V, which swings about an upright stud on the carriage G. This rod Q carries on its screw-threaded parts 00 m, respectively, nuts y y, adapted to abut against a fork Z, in which the rod Q rests, Figs. 4 and 5, said fork forming a part of a block S, mounted on the bridge-piece J at one side and held in position by means ofa screw a. The front end of the rod Q terminates in a fork b, Fig. 11, which is coupled to a pin 0, that plays in a slot d in the plate U. The pin 0 engages at its upper end two superposed arms V V, provided, respectively, with slots e and e to allow of the position of the arms V V being regulated relatively to the pin 0. On the upper end of the pin is a nut f. The plate U is adapted to turn about an upright pin X over the fixed plate U. The plate U is rendered immovable with respect to the fixed plate U in each of its respective extreme positions by spring detents or bolts 76 and k adapted to engage, respectively, bolt sockets or recesses i and i in the plate U, the bolts acting under the influence of springs, as y" in Figs. 9 and 10. At the upper part of the respective bolts are elbow-levers m and m one arm of the lever beingcoupled to said bolt, the other being free and pendent. The respective arms V and V bear on these pendent arms of the levers m m The bolts /c and 762, respectively, play in cylindrical guides n and n mounted, respectively, in slots 0 and 0 in the plate U, wherein they may be adjusted and clamped fast by nuts 1) and p 011 the respective guides are integral flanges g and g Fig. 9, situated in a recess formed in the under side of the plate U under the slots 0 0 and covering-plates u and a under the respective nuts 19 and 29 cover the slots 0 and 0 The operation of the mechanism is as fol lows: In Figs. 1, 5, 8, 9, 10, and 11 the cutter-shaft O is supposed to be in the position it occupies after the cutter-head, moving from rear to front, has made the first cut of the recess and has swung over about the pin X) in the direction of the arrows in Fig 5 and the carriage G is moving back (to the left) to effect the second cut of the recess. In this position the bolt 76 at the upper part of Fig. 5 has entered the socket i and the bolt 7c has been raised by the arm V impinging on the pendent arm of the lever m. The movement of the carriage G back or toward the left carries back also the plate U, the pin X, the plate U, and the whole of the cutter mechanism. When the cutters shall have traversed the width of the tie T and completed the recess or gain therein, the stop g on the rod Q impinges on the fork Z, and the movement of the rod Q with the carriage is arrested. The carriage continuing its movement, the plate U also continues to move; but the rod Q being unable. to move the said plate U can only move bodily the slight distance allowed by the space (1, Fig. 11, between the pin 0 and the end of its slot. During this slight movement of the plate U all of ICC the parts carried by it move, arm of the bell-crank m at the bolt 7r impinges on the arm V, the pin a of which is arrested because the rod Q, connected thereto, is immovable for the time,the rod Q is being arrested, while the pin X continues to move with the carriage. By reason of this stoppage of the arm V the bolt k is disengaged from its socket and the plate U is re leased, so that the movement of the carriage toward the left causes the said plate to turn about the pin X and swing back the cuttershaft G into position at the next advance to make the first cut of the gain in the succeeding tie to be recessed. In the movement just described the arm V, which was before, Fig. 9, pressed against the pendent arm of the bell-crank m, will have been withdrawn and the bolt 7c put in condition to engage its socket i when the plate U shall have turned far enough, and this again locks the plates together.

Figs. 12, 13, and 14 are illustrative views showing how the recess in the sleeper is made at two cuts, the cutter being shifted after the first cut. Fig. 12 is a side view of a sleeper T, showing a recess partly cut in itat T the other part r being designated by dotted lines. Fig. 13 is a plan view showing the cutter A in position to cut that portion of the recess seen in Fig. 12, and Fig. 14 is a plan view showing the sleeper in full lines and the cutting mechanism shifted laterally, so as to cut the remaining part r of the recess. It will be understood that by varying the positions of the bolts 76 and k in their respective slots 0 and 0 the extent af angular displacement of the plate U about its center may be modified or varied, and consequently also the extent of lateral swing of the cutter-shaft C. Hence the width of the gain or recess cut in the tie T may be varied within limitsthat is to say, the gain out may be only equal in width to the diameter of the cutter-head, or it may be nearly double that in width. It may be explained here that the motor IV is capable of turning about an upright axis on its carriage at its mounting to freely permit of the lateral swing of the cutter-shaft, and that the cutter-head employed turns about the axis of the upright shaft C, moving forward and back in a horizontal plane over and across the tie. As it is usually required that the bottom of the gain or recess (see Fig. 12) shall be slightly inclined laterally, the cuttershaft will be or may be inclined from the perpendicular to effect this object.
