U' T EDv ST ATE c PATENT OFFICE,
rnnnnnrcx' L. n. sm's, or TORONTO, ONTARIOJA NA DL I CIJAMPL To all whom it may concern:
Be it known that I, FREDERICK L. H. SIMS, a subject of the King of Great Britain, and a resident of the city of Toronto, in the county of York, Province'of Ontario', Canada, have invented certain new and useful Improvements in Clamps, of which the following is a specification.
This invention relates to a clamp particularly adapted for use as a rail anchor, and my object is to devise a clamp which will. fillJthe requirements of a satisfactory rail anchor. Such adevice must be light in weight, e'asily' attached and detached,- must. possessandretain an absolutely secure grip on'tlieflange of the rail, must be capable of being made mainly of standard lines ofsteel, and. which when shipped will occupy a minimum of space proportioned to its mass.
* shown to have a-wedging engagement. The" lzattain' my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which" i Figure 1: is a sectional viewof my improvedclamp along the plane of the side of the reach bar and connected with the base of a railway rail;
Fig. 2 an end elevation of the clamp shown in Fig; 1;
Fig. 3' an end elevation showing two clamps having their cramp bars integrally connected;
Fig.4 a plan View ofthe clamp construct ed as shown in Fig.1; and Y Fig. 5* a plan view of the device puttogether for shipment.
-I-n the drawings like numerals} of'reference indicate corresponding parts'in the different figures. 7
The clamp comprises three" parts; the reach bar 1, the cramp bar or shoe 2, and a wedge key 3, but these parts are so ar-' ranged as will hereafter appear that they may be temporarily-engaged so that they may be shipped as if they were but'ione piece, which is an important feature of my construction. 7
The reach bar is adapted to span the flange of a structural metal member as A hook 4 is formed on one end of the bar adapted to engage the flange, and this-hook is preferably provided'with a lip 5 adapted to overhang to hold the reach bar in position during the attachment of the de- Specification Of Letters Patent.

Application flled'lebruai'y 9 f lrender it unnecessary to-provide any largeamount of lost motion. in the fastening-de-;
vice.- Thefother end of'the reach bar is bent upwardly and inwardly to form a hook 6, the end of the'bent over portion extending over toward-the flange of the railand pref-1 erably engaging the same as shown. A slot isthus formed in substantially the same plane-"as the edge of the rail flange. The
cramp bar 2 has its upper end" doubled to embrace the reach bar. This doubling is best effected by bending a: portion 7 backparallel to the main portion of the crampbar. Each portion of the cramp bar has a shoulder 8 formed thereinadapted to engage' the under side of the flange.-' The book 6 of the reach bar-are shaped as result is that whenthe'wedge key; 3 is driven between the bend 10 and the'cramp bar thezend of the hook 6-is pressed forcibly against theuppersurface'of the rail flange" and the shoulders 8 drawn up forcibly against the under side of the rail-flange,
thus providing very effective grip of the. device'against the flange. As described,-

they are forcibly jammed over therail'flange,
which is, er course, of the usual tapered low its center so as to avoid any rolling action on the tie, and the lower end 12 is preferably rounded as shown to preventdamage to the tie. It is further desirable that there be a certain measure of resiliency in the cramp baror shoe, and I therefore bend the cramp bar as shown in Fig. 3 to form the sinuosities 13, preferably close up toward the reach bar. 7 3 P When two anchors are required close together, one to resist rail creep in one di-- rection and the other railcreep in the opposite direction, the cramp bars of each. anchor cent edge; a cramp bar bent double to emreach bar end having a wedging engagement brace the reach bar and having a shoulder Whereby the latter is forced toward the formed on each part adapted to engage the flange as the key is driven home in the slot. 10 under surface of said flange at the aforesaid Signed atToronto, Canada, this 8th day 5 edge; and a wedge key adapted to be driven of February, 1921.
