SELF-ACTING SAFETY-GATE FOR SWING-BRIDGES.
SPECIFICATION forming part of Letters Patent No. 352,251, dated November 9, 1886.
v Application filed February18, 1886. Serial No.'192,372. (No model.)
To all whom it may concern:
Be it known that I, HENRY MAROHETER, a suloject of Her Majesty Queen Victoria, and a resident of Wallaeeburg, countyof Kent, and Province of Ontario, Dominion of Canada, have invented new and useful Improvements in Safety-Gates for Bridges, of which the following is a specification.
-My invention relates to improvements in gates for swing-bridges using weights to pull up the gate, and a lever acted upon by the swing part of the bridgeto force the gate down out" of the way. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure'l is a side view of the approach, showing the gate up in place, the swing part being away at this time. Fig. 2 is a similar view, but shows the gate lowered and out of the way as the swing is returned and rests on the lever, thereby lowering the gate. Fig. 3
, shows the iron bearer attached central and u nderneath and at the end of the swing, and is so adjusted that it will ride upon the end of the lever that projects beyond the end of the approach, and gradually pulls the gate down until at last it rests its maximum bearing and continuously holds thegate down.
.Similarletters refer to similar parts th roughout the several views.
A is the approach.
B Bin the drawings show the uprights ofthe gate now up in place with F, which is a rod of iron or wood, and forms the top of the gate. The gate can be made of any material or shape most desirable.
O is the weight, I grooved wheel, and D the chain.
E is a sheath to keep the end of the lever in place.
G is the lever, and H the the united levers G. t
I is the grooved wheels for chains to run in.
J is the fulcrum, and K in Fig. 2 shows the swing end of the bridge resting on the projecting lever-head H.
L in Fig. 3 is a part of the timber of the projecting end of swing, on the extreme end of which the beareriron Mis attached, (shown in Fig, 3,) theiron bearing M just sliding onto the lever-head,
ous movement of the gate.
In .putting up a gate on an approach made with open timber the machinery can all be put inside the same, duplicating the weights, wheels, and chains, as in solid abutments, to hold up the gate, and put anywhere best to op.-
erate on the gate; and the device for putting down the gate by leverpower can be the same as in solid abutments;or, if desirable, one central lever of sufficient strength may be used, and also, if the gate can, according to circumstances, be set well back, a single leverand only one wheel can be used. In this arrangement the end of the lever through the chain acts directly on the gate in pulling it down; but in all cases the end of the lever mustforrn the projecting head H, in order that when the swing comes to the iron bearer will ride on the top of the head H and pull the gate down.
Having thus described the different parts and their relations to each other, I will give a general idea of my invention.
, It will be seen that to have a gate self actingby the weights so arranged as is seen in speeifi-I cation and description given. The second thing to be attained is the getting the gate out of the way when the swing comes to place, so that it is not an obstruction to travel. Advantage is taken of the swinging of the bridge, giving a free power and use for pulling the gate down just at the right time; and when the gate must be removed as the swing is coming to place, the iron bearer M strikes the lever-head H, the lever being pressed downward by the contact,
2. The combination,with the rising and falling gate, of the chains D, passing oppositely from the lower part of the said gate over the t5 sheaves I, arranged substantially as described, and at their ends connected respectively to the weight 0 and lever G, substantially as and for the purpose set forth.
