SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 324,526, dated August 181, 1885.

Application filed June 1'7, 1884. (No model.)

.To @ZZ whom itmay concern.-

Be it known that I, DAvID BOWEN, of Topeka, in thecounty of Shawnee and State of Kansas, have invented a new and Improved Switch-Stand, of which the following is a full, clear, and exact description.

My invention relates to railway switch stands; and it has'for its object to provide a stand having a separable construction of its parts, so that the operatingspindle and its connections to the shifting or bridle bar of the switch-rails may readily be reached for repair or renewal; and also to provide a mechanism for shifting the switch-rails, which shall be protected in the base of the stand, and shall admit of a direct parallel motion of the shifting-bar, and shall also afford a strong lateral bracing of the bar to prevent disabling of the switch by the displacement of the bar.

The invention consists in particular constructions of parts of the stand and its interior mechanism and combinations of the mechanism with the shifting-bar and the switch-rails, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a vertical sectional elevation of my improved switchstand and connections to the switch. Fig. 2 is a plan view thereof. Fig. 3 is a sectional plan view at the base of the stand. Fig. el is avertical sectional eleva tion taken on the line x x, Fig. 3, and Fig. 5 is a detail side sectional elevation oi' the head of the switch-stand.

The switch-stand casing consists of a baseportion, A, by which the entire stand and its mechanism is supported on the cross-tie, a een tral post portion, B, and a head portion, C.

I make the base A in two principal parts, a part, A', to which the post B is rigidly connected either in the casting or otherwise, and a part, A2, which has a iiange, a, along the under side to engage the edge of the tie T, and a broad transverse backward extension-plate, a', which lits a recess made in the bottom of the part A', and has also an edge flange, a2, which is turned up along the back edge of the part A', and preferably in an edge recess of Y the latter, as shown. The upper faces of the base-plates A' A2 lie in the same plane, so that the forked end D' of the connectingrod or bridle -bar D, which connects the switch-rails to the shifting mechanism in the switch-stand, may ride evenly over the baseplates. I show the joints of the plates A' A2 as formed in a series of abutting square and angular edges, (see Fig. 3,) which, together with the lock of the ange a2 at both its ends and the lock of the flange a of part A2 in the bottom recess of the part A', hold the baseplates A' A2 together firmly and against end, movement one on the other. The iit of the part A around the flange a2 of the part A2 also holds the part of plate A2 which overhangs the tie I up truly level, where it is held by the weight of the parts A B and the head of the stand, and also by a number of bolts, lag-screws, or spikes, passed through the plate A into the tie. A flange, a2, rises from the outer edge ofthe base-plate A2, and a plate, A3, fitted on this flange and on the plate or portion b of the post B which overhangs the inner arm, d', of the fork of the bar D, forms a removable cover, which is held to place by screws a5, as shown. A rabbeted bead, c, on the cover-plate A2 covers thejoint between the plate and the part b of the post B, (see Fig. 2,) so as to exclude rain or snow from the switclrshifting mechanism set within the base of the stand. A slot, al, is provided at each side of the stand, so that the bar D may pass either to the right of the stand, as shown, or to the left of it; and I provide a cover plate or strip, a2, to be fastened by screws or otherwise over the slot not occupied by the bar D,to exclude storms and strengthen the connection between the base-plates A' A2.

.The head C of the switch stand consists of two main parts. The part C' is held to the top of the post B by screws e, entered through a pendent lug, c', formed on part C', and also by screws c2, which pass from the back of the stand through lugs b, formed on each side of the stand, into lugs ci, also formed on part C'. (See Fig. 5.) The part or cap O2 of the head is held above thepart Osuliiciently to allow the arm E of the operating-spindle G to have free play between the parts C' C2, and by the same screws, c c2, which hold the part O to the post B. In holding the cap C2 to the IOO post B the screws c pass clear through the stand from the front and into a iange, c4, which hangs down from the back edge of the cap, and the screws c2 pass through the lian ge c4 into the lugs b c3 from the back, the screws c and cZ at each side of the spindle G of the stand thus serving to firmly hold the entire head C to the post B, and so that the head may readily be dismembered and removed at any time.

l The spindle G of the stand is journaled in a box formed half in a lug on the post B and half in the lug c of the head C for an upper bearing, and in a box formed half in a lug on the post B and half in a cap, b, screwed `to the post, for a lower bearing, and so that when the head C and cap b4 are removed the spindle G, with its rigid arm E and lever F, may belifted from the stand without loosening the basefastenings of the stand to the tie.

The Operating-lever F is pivoted on a pin, f, to the outer end of the arm E, and so that when the lever hangs down vertically its end f will pass up into one of three slots, H, made in the top of the cap C2, and a lug, f2, xed at a right angle to the lever F, will pass into a corresponding slot, 7i, made in the pendent flange h at the edge of the cap. The lugf2 has a hole through its outer end to receive the hasp of a lock, a pin, or other fastening outside of the iiangeh, to lock the lever in any position at which it may be set in shifting the switchrails. The hanging` lever F also passes into edge slots, h2, of the head-plate C, to more rmly lock the lever to place. StopV lugs or pins I are provided on either plate C C2 of the head C to limit the side swing of the lever by contact of the spindle-arm E with them when the lever F is in position to lock into the slots Hh h2 at either side of the head C for holding the switch -rails to the turnout at either the right or left of the main track, as will be hereinafter described.

The spindle G projects above the head G of the switch-stand to receive a suitable light or other signal, and has a fixed collar, g, which rests above its lower bearing and serves to support the spindle so that its fixed horizontal crank arm, J, will swing in a true plane.

I connect the rod or bridle-bar D to the spindle G by means of a sliding block or head, K, in which the wrist-pin at the end of the crank is loosely itted, and I place said block K loosely upon a cross rod or bar, L, which connects the two arms or members d d2 of the fork D of the bar D. The ends of the arms cl d2 are bent to act by dat faces between the rear shoulder, Z, formed along the back of the base of the stand and the front iange, at, of the base of the stand, whereby the bar D will be guided laterally, so as always to move flat against the side face of the tie and through keepers M, fixed to the tie.

But one of the rails of the main track and right and left turnouts are shown in Fig. 2,-

but they sufficiently illustrate the action of the switch-stand.

By setting the lever F in the right-hand notch H the switch-rails N will be moved to 7e connect with the rails O of the right-hand turnout, as in Fig. 2.

By setting the lever F in the front notch H the switch rails N will align with the maintrack rails l?, and by setting the lever F in the left-hand notch H the switch-rails N will connect with the rails Q of the lefthand turnout.,

It will b'e seen that as the spindle-crank .T is swung around by the lever F the block K 8o slides along the rod L, and the rod or bridle-bar D has always a direct motion parallel with the -f tie, and the bar D is held sidewise or latwise so irmly in the stand and along the tie and in the keepers M that neither the bar nor the'85 switch-rails can be displaced or shifted by driving vehicles over the bar, which has no joints of any kind between the rails and the switch-stand; and by the separable construction of the stand all. the parts are readily accessible for repair or renewal when required.

An oil-hole is provided at o in the cover A3, through which the bearings of the block K on the bar L and of the crank wrist-pin in the block may be lubricated when required without removing the cover.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
