Specification of Letters Patent.

Patented Nov.22,1921.

Application filed August 12, 1921. Serial No. 491,811.`

To all whom t may concern:

Be it known that I, MnLviN OvEsTRUD, .a

vcitizen of the United States, residing in l clamping, scoring pin.-

Stillwater, in the county of Washington and State of Minnesota, have invented a new and useful .Combination Tie-Plate and Anticreeper for Rails, of which the follow.- in is a specification.

y invention relates to improvements in conlibination tie-plate and` anticreeper for rai s.

Its object is to provide a durable device of this kind, which is simple in construction, readily applied and capable of functioning efficiently through long continued use.

A further object is to supply a rail anchor adapted to abut against a tie and capablo of securely gripping a rail without danger of accidental slippage.

Another object is to supply a device, as above, supplemented with a tie-plate integral therewith and adapted to be secured to a cross-tie by ordinary rail spikes.

Ay further object is to supply an attachment for rails including a cutting element adapted'to score the base of the rail under yielding tension 'wh'en the attachment is applied to the rail and also adapted to lock the attachment under yielding tension after application thereof to the rail.

With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in' the details of construction hereinafter described and claimed.

ln the drawings, Figure 1 isa perspective view of a device embodying my invention; Fig. 2 is an enlarged View illustrating the same as applied to a rail and crosstie, the yoke and rail lbeing shown in crosssection; Fig. 3 is a Asimilar lfragmentary view showing the pinv at the beginning of its clamping, scoring thrust; lFig. 4 is a detail sectional view taken on the line l4--4 of 2 and Fig. 5 is'an'end view of the Having reference to the drawings, it will be noted that Thave used the reference letter A to indicate the tie-plate member and the letter B to designate the rail clamping yoke of my improved rail attachment. The tieplate A and yoke B are integral, the same being struck from a single blank. The tie I plate consists of a iiat sheet 10 having spike receiving apertures 11 therein. The yoke includes a strip 12, severed from the sheet, except throu h a limited area near one end thereof. This strip 10 is depressed medially to a point considerably beneath the plane of the sheet 10 to form a tie-abutment. Said strip, thus depressed assumes the form of a yoke, (Fig. 1) the ends thereof being turned inward to form - jaws 13 and 14 adapted to receive the opposite margins of the Vbase of a rail (Fig. 2.) The jaw 14 on the fixed end of the yoke is deeper than the jaw 13 at the other end thereof to permit the application of the yoke A to the base of a rail at any point desired. This feature will be appreciated, since it obviates the necessity of slipping the attachment over an end of a rail, as is required in other forms of anticreepers. The opposed members of the jaw 14 have apertures 15 therein to receive a clamping, scoring pin 16. This pin, tapered as shown, is adapted to be driven downward throughthe apertures and the inner side thereof bears against the edge of the base 17 of a rail. 4The wedging action of saidv pin results in a firm y1elding grip of the yoke A upon the rail base.

vThe inner side of the pin 16 is serrated as at 18 to form a concave cutting surface, a concave locking depression 19 being formed in said side of the pin above the serrations 18. During the clamping thrust of the pin 16, said cutting surfacescores the edge of the rail base abutting thereagainst. This scoring action is produced under increasing yielding tension of the yoke A. The pin 16 registering in its downward thrust with the scored depression .then being formed in the lrail base, is secured against accidental displacementlby the locking de-` pression 19 in saidpin, said depression being drawnY into registering or interlocking relation with the scored depression, by the resilient action of the yoke A. Thus it will be seen that the yielding grip of the oke This attachment against the tie, supplies a tie protecting and ends thereof adapted to receive the opposite margins of the base of a rail, one of said jaws having registering apertures in the opposed members thereof, and a tapered locking pin designed to be driven through said 'apertures and against the edge of the rail base to cause the yoke to yieldingly grip the rail, the side of said pin contacting with said base being formed with a cutting surface to score the edgethereof and also formed with a locking depression above the cutting surface adapted to catch within the scored depression in the base, said locking depression serving to secure the pin against accidental displacement, said pin serving further, in registering with the scored depression, to supplement the yielding grip of the yoke upon the rail and thereby firmly seclpre the rail against slipping within the y 2. A device of the class described,` comprising a tie-plate, a yielding tie abutting yoke integral with said plate and having jaws at the ends thereof adapted to receive the opposite margins of the base of a rail, one of said jaws having registering apertures in the opposed members thereof, and a tapered locking pin designed to be driven through said apertures and against the edge of the rail base to spread the yoke and cause the 'same to yieldingly grip the rail, the side of said pin contacting with said base being formed with a cutting surface to score the edge thereof and also formed with a locking depression above the cutting surface adapted to catch within the scored depression in the base, said locking'depression serving to secure the pin against accidental displacement, said pin serving further, in registering with the scored depression, to supplement the yielding grip of the yoke upon the rail and thereby firmly secure the rail against slipping within the yoke.

3. A device of the class described,com prising a yielding yoke having jaws at the ends thereof adapted to receive the opposite margins of the base of a rail, one of said jaws having registering'apertures in the opposed members thereof, and a tapered locking pin designed to be driven through said apertures and against the edge of the rail base to cause the yoke to yieldingly grip the rail, the side of said pin contacting with said base being formed with a concave cutting surface to score the edge of the base, said pin in registration with the scored depression formed thereby serving to prevent slipping of the rail with respect to the yoke by supplementing the yielding grip of the yoke upon the rail.

4:. A device of the class described, including a tie-plate and a yielding tie-abutting yoke struck from a single blank, the tie-plate having spike receiving openings and the yoke being formed aty its ends with jaws adapted to receive the margins of a rail base, one of said jaws having alined pin receiving apertures, a tapered pin adapted to be driven downward through said jaw, said pin being guided by said apertures and brought to bear against the edge of the rail base, thus causing the yoke to yieldingly grip said rail, said pin being formed with a locking depression near the upper end thereof designed to catch upon the edge of the rail base and secure said pin in yoke clamping relation.

5. A device of the class described, comprising a tie-plate, a yielding tie-abutting oke integral with said plate, said yoke havmg jaws at the ends thereof adapted to receive the opposite margins of the base of a rail, one of said jaws having registering apertures in the opposed members thereof, and a tapered pin designed to be driven through said apertures and against the rail base to cause the yoke to gripthe rail.

6. A device of the class described, comprising a tie-plate, a yielding, base-embracing yoke integral with the tie-plate and forming a tie-abutment and a pin adapted to coperate with the yoke and the base of a rail to cause the yoke to grip the rail.

7. A device of the class described, comprising a tie-plate, a hase-embracing yoke integral with the tie-plate and forming a tie-abutment and a pin coperating with the yoke and the base of a rail to cause the yoke to gripl the rail.

8. A device of the class described, comprising a tie abutting yoke designed to embrace the base of a rail and a pincoperating with the yoke and rail to grip the former upon the latter and to score the rail base during the gripping operation, the pin being formed with a locking depression therein arranged to register with the depression cut in the rail base by said pin.

In testimony whereof I have signed my name to this specification.

MELVIN OVESTRUD.
