I This invention relates to a safety block for mine and other cars, the general object of the invention being toprovidemeans for chockinga pair of wheels er; a car,z with means 6v whereby the device can beeasily and quickly placedin position withoutthe useofbolts, clampsor other fastening'rneans, due to the peculiar shape of the rail engagingmembers which automatically adjustkthemselveson the tread portions of the rails tofstopa car' when :3 pair of wheels of the car strike saidfimemers. A This invention also consists-in certain other features of construction andin the combination andarrangement ofthe several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically-- pointedout in the'appended claims. In describing the invention in detail, ref; erence .will be had to the 'accompanying. drawing wherein like characters denote like i orcorresponding parts. throughout the several views, and inwhich:
Figure 1 is a sectional viewthrough a track, showing the invention in use, i Figure 2 is a plan view of'Figure '1 Figure 3 isadetailvi'ew showing awheel 1n engagement with one of the track mem- Y I i strike the two members 5,-the device'will beq' i tilted to the position shown in Figure13-,*so
that theiflat part 7 will rest squarely-on the bers.
Figure vice. 2, j V
Figure 5 is a section on-line -55 of Figure 4, g 1. 1,
Inthese views,lthe numeral 1 indicates I a flat barof such a length that it will extend beyond the tworailsof, aj-track. when the device is in use; withone end extended to form a handle 2. A pair of rail engaging [members 3 have their horizontal portions-4 I suitably fastened tothe bar, with their rail" ,engagingportions 5 vextendingupwardlyat a 4; is a perspective-view the deportion 5 is formed with a head 6 having a substantially. flat under face 7' which slopes upwardly and rearwardly fromthefront end of thehead, so that the front end of the head hasgreater. thickness than therear end. 1 i
V An upstanding flange'S- is formedon the front end of the head and a depending part ais formed on the free edgeof the head so as to provide a space between itself and the part 5iniwhich the tread part of the rail fits. An upstanding flange. 10 is formed on the free'edge ofthehead, this flange being diagonally arranged and forms a groove 11 between itself and-the head. 7 This flangelO and the groove act as .derailing' means if a the wheel should pass over the-'flanger8, as the flange oftheiwheel will passinto the groove 11 and'thus be deflected by the flange 10' and .60 said groove to the outside portion of the head a so that the wheel will pass from the rail and I thus the car will be derailed. The flange of the opposite wheel-would, of course, pass the inner portion of the part5 as said opposite e5 wheel followed the movement of thefirst 1 wheel. I The head of the member engaged by said opposite wheel is provided with anotch ,12 at the) front end of'theinnerpart of-the" 1 hea'd to receivea part of the flange ,of theym wheel so that the tread Lportions of-both wheels'will strike the front ends of'thelieads squarely on the track. The derailing partsj V v 6 at the same timeandthus keepthe car v of the left hand member mayf-be omitted as,
y of course, these'derailing parts are notneces 'sary on this member.
Aslwillbe seen, whenthewheelsof-a'car treadiof the rail. The'enlarged frontends of: v the heads Got the rail engagingmemberswill act: to stopthe car, but if the momentum of the car is-too great the derailingfeature s5 i I willcorne into action and thus derail the'can' Iti's simply-necessary to holdthe device by the handle 2 andlpush it under-ithe rails, I
just behind atie and then give it a twist in j the-directionoftravel of'the car so'ithatithe 7 f I heads will engage the tread portions ofthe rails. ;-Thejdevice is then in place 'and 'wil-lJ act-to-stop or derail' a car, as before described. I
The device will instantly adjust. itself in place and is held in place by the peculiar are5 I rangements of the head parts and the device- Q can be easily and quickly removed.
It is thought from the foregoing descrip tion that the advantages and novel feature of the invention will be readily apparent. r00
