RAILROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 390,618, dated ctober 2, 1888.

Application filed April 21, 188B. SerialNo. 271.404. (No m del.)

To all whom it may concern:

Be it known that I, WILLIAM RIDING,a citizen of theUnited States, residing at N orristown, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Railroad-Gates,which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in IQ railroad-gates, the primary object of the invention being the production of railroad-gates which will have very few working parts, whereby liability of the gates working out of order from the constant usage to which they I5 are subjected is prevented, the gates are rendered easier and more efficient in operation than heretofore, and whereby also the gates can be supplied at a very small expense.

My invention relates to improvements in 2c railway-gates; and it consists of an oscillating shaft which carries the gate, having a cam, to which is attached a belt or band with a weight thereon also, in providing the oscillating shaft having a cam and weighted belt with a motor consisting of a rotary shaft, lever, and radial arm, the latter being secured by a link to the cam; and, further, of the combination and arrangement of parts as herein set forth and claimed.

Figure 1 presents a side elevation of a railroad-gate embodying my invention. Fig. 2 presents a vertical sectional view thereof, the operating parts of the gate being in the position they assume when the gate is down.

Fig. 3 presents a similar view, the operating parts of the gate being in the posit-ion they assume when the gate is up.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the casing or housing which contains the mechanism for operating the gates.

B designates a shaft mounted in the upper portion thereof, carrying a gate, G,of the wellknown construction of railroad gates. On the shaft B is secured a cam, D,to the periphery of which at the proper point is secured one end of a band or belt, E, and to the other end of the band or belt is attached a weight, F, which is guided in its vertical movement by means of the rod F, which passes through it. The purpose of the weight is to form a counter-balance and thereby assist in elevating and lowering the gate.

G designates a shaft mounted in the lower portion of the casing, having a radial arm, H, secured thereon.

G designates a hand-lever secured to the shaft G outside the casing, and this lever carries a pawl, g, operated by a small lever, 9, connected to it, and the lever g has a spring, 9 to cause the pawl g to engage the rack-bar J on the side of the casing.

K designates a link or bar connecting the arm H and-the cam D,for communicating the movement of the arm to the cam.

K designates a drum mounted loosely on the stud Z, and which serves as a guide for the band or belt from the cam.

M designates a lamp pivoted to a bracket and carried by the gate.

The operation is as follows: When it is desired to lower the gate,the pawl is disengaged from the rack and the hand-lever is thrown to the right, causing the arm on the shaft therewith to move downward, and by reason of its being connected with the cam to carry said cam down also, and thus lower the gate. To raise the gate, the lever is thrown to the left, causing the arm to rise, and consequently the cam and gate, the weight serving when the gate is being lowered to prevent it from being lowered too rapidly and when being raised to assist its ascent, the weight thus serving as a counter-balance, and effectually preventing shock or breakage to. the parts. By reason of the cam and arm increasing power is applied to the gate, causing it to be raised and lowered with ease and rapidity, which is a great advantage over the existing gates,which require a considerable expenditure oftime to raise and lower them; also, by reason of the few parts which compose my gate, liability of its working out of order or breaking is prevented,the operation is rendered more efficient,'and the same can be produced at a very small expense, thus providing a gate possessing all the features of merit and one calculated to recommend itself.

Havingthus' described myinvention, what I 100 claim as new, and desire to secure by Letters Patent, is

1. In a railroad gate, a shaft journaled thereon carrying the gate, a cam on said shaft, a belt or band on the periphery of the cam, a weight connected with said belt, and mechanism for rotating said cam, combined substan' tially as and for the purpose described.

2. In a railroad-gate, the combination of a shaft carrying the gate and having a cam mounted thereon, a weight connected to said cam, the shaft having the radial arm, the bar or link connecting said arm and cam, the lever for rotating the cam, and the pawl and rack for retaining the lever at the desired place, all combined, arranged, and adapted to serve substantially as and for the purpose described.

3. The shaft B,having suitable bearings,the gate C, mounted thereon, the cam D,with belt E secured thereto, the weight F, attached to said belt, the guide-rod F, passing through said weight, the shaft G, with hand-lever G, the arm H, secured to said shaft G, and connected by the link K with the cam D, said parts being united substantially as described. 25

4. The shaft B, with gate 0 and cam D thereon, the beltE, secured to said cam and to weight F. the vertical guide rod F for said weight, the guide-drum K for said belt, a rock-shaft with operating-lever, an arm and link connecting said rock-shaft to said cam, a rack-bar, and a lever with aspring-pawl engaging the teeth of said rack,said parts being combined substantially as and for the purpose set forth.

WILLIAM RIDING.
