tionthereof; V j 'In the accompanying drawing, illustrative of one embodiment of the invention proved catch in its simplest formas applied 7 to a railroad switchstand handle;
Figure .2 is a vertical section through'a' slightly modified form of lock or catchillustrating the same as 'beingflho-used in and locking means applied thereto; while Figure 3 is a broken perspective view showing the locking means,'with the cover removed.
The necessity of a dependable lock or catch fora switch handle is well known to those versed in the art as well as the advantage of simplicity in constructiom to accomcplish which I have illustrated my improved catch as mountedjupon a metal plate illusdesiredmannerto the switch handle 2, the upper end of which is pivotally attached to the switch throwing mechanismf'above the v laterally protrudinglug 3 from the switch stand at, to which the handle is securely at tached whenthe switch is closed. The plate bracket 1 extends somewhat outwardly and upwardly from the handle where, it is bent laterally at right angles forming the two spaced lugs5 and 6 in which is pivotally mounted the horizontal arm- 7" of the catch ordog comprising said horizontal portion as I well as the other portions thereof indicated at 8, 9, 10,'and 11, the same being'ofa; single piece of round iron or steel; The twoportions 7 and 9 are substantially parallel though the latter somewhat shorter than the former and being spaced therefrom in an overhanging manner is constantly susceptible to the influence of gravity, and only prevented from normally remaining with the endor finger 11 normally impinging against 7 the-plate lfby a suitable lugl' or projection 12 formed either'upon the lower outer corner of the lug or upon thecorner of the covswitches; the principal object being to pro Figure 1 is'a perspective View of an im-;

outer surface of the plate 1 so that when the f handle 2 is thrust downwardly along saidg' lug 3 on the switch stand, which is provided with a suitableh-ole 14 for the reception ofthe finger 11, said finger will slip past the? chamfered. end of the lug 3 and be forced into the hole 14 by thegrav'itating'efiect of the dog. .To facilitate'this operationI pree H 17 fer also to chamfer or bevel the extreme end ot vthe finger 11 so that the motion'past the;

By'such av simple attachment it is evidentthat the switch handle 2 cannot: be fully I closed without-the catch or'lock fun tioning,
