Description
`my improvements.
CHARLES WINTER, or cnILLIooTHE, omo.
IMPROVEIVI ENT IN CLAW-BARS.
Spcciiieation forming part of Letters Patent No. lllQAOLdatcd March 7, 1871.
To all wwmlzlt may concern:-
`Bc it known that I, CHARLES WINTER, of
, which permitsthe withdrawal and reversal or .l renewal of `either of the claws in case they should become broken. l v
In the accompanying drawings. Figure l is a perspective View of a` claw-bar embodying Fig. 2 lis another perspective view ot' theimplement, showing one ofthe claws and retaining-bolt detached from the bar proper. Fig. is a vertical section in the plane ot' the bolt. ff i A represents the bar proper, which is made of wrought-iron, and terminates at its lower end iu the customary rounded heel or fulcrum' The bar is provided with two sockets, C U.
that are intended for the reception ofthe claws D D', which are made of steel. These claws are exact i'ac'silniles'ot each other, and it will be seen that they are provided with notches d d, which are made in the opposite edges ot' said bars D D', and near the ends ofthe same. lThe extreme ends ot' the claws are curved, as at E E', so as to correspond with the shape of the heel B. lhe metal or web a, which intervenes `between the two recesses C C causes the claws D Dto be separated a sufticient disl tance toadrnit the body of the spike between thein and cause its head to tit within the out-er notches, d, of the two claws.
F is ya bolt, which traverses the devices a D D', andsecures them iirmly together.
either of,tljie claws should break at the notched portion the bolt F can be withdrawn and the injured clawreversed, so as to bring the other notched portion into use. There being two cla-ws to this instrument, and each claw being provided with two notches, three changes can be made before it will be necessary to entirely renew any oi' the parts. The ability to change the position ot' the claws without putting in new ones is `a great advantage at all times, and especially so when the track-nien are at some remote point on the road where the serviees ot'a`=blacks1nith or other artisan cannot be had.
The claws D Dcan be rapidly and economically cut out of steel plates by a suitable die.
I claim as my invention- The combination, substantially as described, of the claw-bar A a. B, recesses or sockets C C', duplexY claws D D' d d E, and retaining device F, for the purpose described.
In testimony oij which invention l. hereunto Set my hand.
CHARLES WINTER.
