RUFUS R. CANFIELD, 0F CLEARFIELD, PENNSYLVANIA.

RAILROAD-TIE.

Specification of Letters Patent. Application filed May 21 Patented Sept. 7, 1909. 1999. {Serial No. 497,384.

To all whom it may concern: 1 y j Be it known that I, RUFUS R. CANrmLD, a citizen of the United States, residing at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented a new, and useful Railroad-Tie, of which the fol lowing is a specification. I i

It is the object of the present invention to' provide an improved construction of rail-: way tie and the invention relates more spe-' cifically to that class of railway ties which; are metallic and which have rail clamping members readily engageable with and -disengageable from a rail supported upon the tie, and the object of the invention is to simplify the construction of such tieand yet provide rail clamping means which will firmly lock the rail against lateral displace-v ment.

It is a further object of the invention to provide, in a tie of the class described, rail clamping means having a resilient or otherwise yieldable portion and to provide means .or cooperation with such portion to cause the rail engaging portion of theclampinm means to bind firmly against a rail disposed upon the tie. I

The invention further aims in this con-. nection, to provide a means for coo eration clamp-' mg means which will automatically. look when moved to position to cause the saidi clamping, means to bind against a rail upon with the resilient portion of the rai the tie.

A still further object of the invention is to provide means which maybe readily assembled with the tie to clamp a rail thereon in the event of fracture of the integral or permanent rail clamping or engaging permeans being clamped in position through the medium of the-means which cooperate with the resilient portion.

tions of the tie, such of the rail clamping member above referred to. V

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view through one end of a tie constructed ln'ac cordance with the present invention.

Fig. 2 is a top plan View thereof. Fig. 3

isa

vertical transverse sectional view through the saidend of the tie Fig. 1. of the rail clamping member associated .with the tie; Fig. 5 1s a similar view of the looking key for the rail clamping member. Fig. 6 is a view similar toFig. 1 but showingthe on the line 33 'of Fig. 4 is a detail perspectiveview repair. device assembled with the tie, and Fig. 7 is a detail perspective view of the repair device.

Referring more specifically'to Figs. 1 to 5 inclusive of the drawings, the tie is shown as having its intermediate or body portion of substantially the same cross-sectional conp upon the rail supporting head 11, there being a thin block of wood or other yieldable material 15 disposed between the rail and the said upper face of the head 11, the upper face being recessed as at 16 to receive the said bloc The upper wall of the rail supporting head 11, above referred to, is formed with a slot 17 which extends in a direction longitudinally of the head and through which pro jects the head 18 of a rail clamping member including also a resilient shank 19 which extends beneath the top wall 13 of the head and outwardly and slightly beyond the outer end of the head. The head 18 of this clamping member is formed with a lip 20 which engages with the inner base flange of a rail disposed upon the block 15 and it will be 1 stem 21, a cam portion 22, and a head 23 which is preferably of the same general shape as the cam portion 22 and is spaced therefrom and presented endwise toward the same. One side wall of'the rail supporting head 11 of the tie is formed with a slot 24: which is of such size as to permit of passage of the stem 21 and the cam portion 22 therefon,'the end of the stem seating in the opening or seat 25 formed in the opposite side wall of the rail supporting head as is clearly shown in Fig. 3 of the drawings, it being understood that the key is in this manner so supported as to permit of rotation. .The

cam portion 22 of the key and the head 23 thereof are spaced apart a distance equal to the thickness of that side wall of the head through which the slot 24 is formed so that when the key is in the position shown in Fig. 3 of the drawings, the cam portion 22 will lie between the said side walls of the head and the head 23 will lie outwardly of that side wall through which the slot 24 is formed. The shank 19 of the rail clamping member is formed in its upper face with a longitudinally extending rib 26 having a notch 27 therein and upon rotating the locking key 21 from a position in which it is inserted through the slot'2a, to the position shown in Figs. 1 and3 of the drawings, the cam portion 22 of this key will ride over the rib 26 upon the upper face of the resilient shank 19 of the rail clamping member and will finally seat in the notch 27 in the said rib, the key being in this manner locked against further rotation, accidentally, in either direction.

The fact will readily be appreciated, from an inspection of Fig. 3 of the drawings that when the key is in position just described, 7

the opposing ends of its stem portion 22 and head 23 will engage with opposite faces of the side wall of the head through which the slot 2& is formed and that consequently withdrawal of the key without disengaging it from the notch 27 is rendered impossible.

Furth ei'niorefihe resilient shank 19 of the rail clamping member is resilient only to such degree as will necessitate the exertion of considerable force in rotating the key to the position in Figs. 1 and 3 of the drawings, and, in a like manner, considerable force will be required to be exerted to rotate the key from this position.

It will of course be understood that when the key is rotated to posit-ion to disengage from the resilient shank of the rail clamping member, the head end of this member may be readily depressed by grasping its shank end and raising the said shank end and that in this manner the member may be disengaged from the rail and removed bodily from the boss. 7

In the form of the invention shown in Figs. '6 and 7 of the drawings there is provided means whereby a rail upon the tie may be firmly held thereon in the event of fractureof the integral rail engaging portion 1 L of the rail supporting head and to this end, the top wall 13 of the boss is formed, outwai'dly of the rail supporting portion and beside the rail engaging portion 14, with a slot 28 through which, in event of injury to the rail as stated, the head 29 of a rail engaging member is inserted, said head being formed for engagement with the outer base flange of a rail upon the tie. This member comprises, in addition to the head 29, a shank 30 which, when the member is in position upon the head 11 of the tie, extends beneath the top wall 13 thereof as is clearly shown in Fig. 6 of the drawings and this shank 30 is formed in its under surface with a notch 31 in which the upper side of the stem 21 of the locking key of the rail engages, its cam portion 22 engaging the notch in the resilient shank of the first described rail clamping member as heretofore observed.

While the last described clamping member is designed primarily for use in the repair of the tie embodying the present invention, it will be readily understood that it may be 'empl-oyed in conjunction with the rail engaging portions lt of the rail supporting heads of the ties, at switches and other points where the rails are liable to be subjected to considerable lateral stress and that therefore its use is not limited to repairing broken rails.

The under side of the tie is formed, prefe'rably throughout its entire extent, with transverse ribs 32 which dig into the roadbed and serve to prevent displacement of the ties as will be readily understood.

It is preferable that a key 33 be inserted between the portion 14.- and the outer edge of the base flange of the rail and that this key be wedge-shaped whereby the rail may be forced in the direction of the center of the track way should the rails become spread to any appreciable degree.

What is claimed is 1. A tie having a rail engaging head thereon, the said head being formed with :1 slot through its rail supporting portion, a rail clamping member having a head projecting through the slot and having a resilient shank, and cam means upon the tie movable to position to depress said shank and thereby cause the head to bind against the rail upon the tie.

2. A tie having a rail engaging head thereon, the said head being formed with a slot through its rail supporting portion, a rail clamping member having a head projec-ting through the slot and having a resilientshank, and a cam key upon the tie movable to position to depress said shank and thereby cause the head to bind against a rail upon the tie.

3. A tie having a rail engaging head thereon, the said head being formed with a. slot through its rail supporting portion, a rail clamping member having a head projecting through the slot and having a resilient shank, and a rotatable cam key carried by the tie and movable to position to depress said shank and thereby cause the head to bind against a rail upon the tie.

4;. A tie having a rail engaging head thereon, the saidh-ead being formed with a slot through its rail supporting portion, a rail clamping member having a head proporting jecting through the slot and having a resilient shank, the said head being formed through one side wall with a slot, a cam key inserted through the slot in the side wall of the head and rotatable to position to depress the said shank and thereby cause the head to bind against a rail upon the tie, the cam portion of the key engaging with the said side wall of the head whereby to obviate displacement of the key.

5. A tie having a rail engaging head thereon, the said head being formed with a slot through its rail supporting portion, a rail clamping member having a head projecting through the slot and having a resilient shank, one side wall of the head being formed with a slot, and a cam locking key inserted through the slot in the said side wall of the head and having a head and a cam portion spaced from the head and engaging with the shank whereby to depress the same and thereby cause the head to bind against a rail upon the tie, when the key is rotated to one position, the said cam portion and head of the key engaging upon opposite faces of the said side wall of the head when in such position whereby toobviate displacement of the key.

6. A tie having a rail engaging head thereon, the said head being formed with a slot through its rail supporting portion, a rail clamping member having a head projecting through the slot and having a resilient shank, the said shank being formed with a notch, and cam means upon the tie movable to position to depress said. shank and thereby cause the head to bind against a rail upon the tie, the said cam means engaging in the said notch in the shank.

7. A tie having a rail engaging head thereon, the said head being hollow and being formed with a slot through its rail supportion, a rail clamping member having a head projecting through the slot and a resilient shank extending into the said head, and a cam key extending interiorly of the head and movable to position to depress said shank and thereby cause the head to bind against a rail upon the tie.

8. As a repair means for a tie having an integral rail engaging head, the said tie being formed with a slot, a rail clamping member having a head projecting through the slot and engaging with a rail upon the tie and having a resilient shank, a second rail clamping member having also a head engaging with the rail upon the tie and having a shank underlying the rail supporting portion of the tie, and a locking member extending between the shanks of the two rail clamping members and movable to position to bind the shank of the last mentioned member against the said under side of the rail supporting portion of the tie and depress the shank of the first mentioned rail engaging member whereby to cause the head of the same to bind against the rail.

. 9. A tie having a rail engaging head thereon, said head being formed with slots through its rail supporting portion, rail clamping members having each a head projecting through one of the slots and having also shanks extending beneath the rail supporting portion of the head, and a locking and clamping member inserted between the shanks and movable to position to separate the same whereby to cause the head to bind against a rail supported upon the head.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
