GATE.

FJPECIl-ICATIGN forming part of Letters Patent No. 383,920, dated June 5, 1888.

Application filed November 25,1887. Serial No. 256,127.

To all whom it 12mg concern:

Be it known that I, PATTERSON STEELE, residing in the county of Fayette and State of Kentucky, have invented certain new and useful Improvements in Gates, of which the following is a specification.

My invention relates to that class of gates designed to be actuated manually by persons on horseback, in vchicles,orafoot on approaclr ing and after passing through the gateway, and more particularly to such as are moved longitudinally by means of levers at the side of the road and some distance from the gate.

The present invention is designed as an improvement upon the gate for which Letters Patent were granted to me bearing date the 22d day ofMarch,18S7, and numbered 359,746.

The annexed drawings illustrate my invention, Figure 1 being a perspective view of a gate constructed in accordance therewith Fig. 2, a perspective View of the principal parts of the actuating mechanism; Fig. 3, a side elevation of the same; Fig. 4, an edge view of the canrwheel by which the reversingpinions are shifted; Fig. 5, a view illustrating the manner of connecting the gate with its operating mechanism; Figs. 6 and 7, detail views of the clutch by which a return movement of, the hand-levers is permitted to take place without rotating the shaft or giving motion to the actuating mechanism; and Fig. 8, a detail view of the latch mechanism.

Referring again to the drawings, A indicates the gate proper, provided with a runner-bar, B,

which, as in my former patent, runs upon or.

between suitable supporting and guiding roll ers, a, applied to a post, 0, and upon the main impelling wheel or drum D. Other supporting and guiding rollers may obviously be provided, if desired, though not deemed neces sary.

The wheel or drum D is keyed or secured upon a shaft, E, which is journaled in hangers or bearings b, bolted or otherwise made fast to a main post or upright, F, as shown in Figs. 1, 2, and 3. Shaft E is furnished with a spline or feather, c, and is encircled by a sleeve, G, Fig. 3,having a groove, d, to receive the spline, whereby the sleeve is enabled to move freely-lengthwise upon the shaft, but by which provision the two are compelled always to rotate in unison.

(No model.)

with acircumferentially-grooved neck or hub,

c, which receives the encircling collar or section of a box or bearing, K, bolted topost F, as shown in Figs. 1, 2, and 3, the pinion being thus held against vertical movement, but left free to rotate.

L indicates an upright drum or cylinder provided with two helical grooves,f, running from end to end, or nearly so. The upper end of this cylinder is journaled or supported in a bracket, 19, bolted to post F, and the lower end is reduced in diameter, as shown in Fig. 6, forming two sections, 9 and h, of different diameters, the section 9 being encircled by a clutch sleeve or collar, i, and resting at its end upon the upper end of hub e of pinion J, while the lower section, h, passes centrally through the pinion, as shown. The lower section or journal, h, of cylinder L is free to turn within and independently of pinion J, except at such times as it is locked thereto by'the clutch sleeve or collar t, which is provided with ratchet-teethj,to engage with corresponding teeth,j, of the hub e of pinion J, as shown in Figs. 1, 2, 3, 6, and 7. Clutch-collar i3 is not rigidly secured upon neckg of cylinder L, but is loose thereon, so as to permit limited movementofeither independently ofthe other. Connection is, however, made between them by means of a pin or stud, k, projecting from neck 9 into or through a rectangular opening, Z, in the clutch-collar i, as best shown in Figs. 6 and 7. This opening is of a width and height considerably greater than the diameter of the pin 7c; hence cylinder L and its neck g and pin may be moved or turned a limited distance before the pin will come into contact with the side walls of the opening, and the collari may rise and fall, so that in turning it backward its teeth may ride back over those of the pinion j, thereby leaving the pinion at rest.

Y M indicates a yoke, which straddles the cylinder L, and the two arms of which reach from above the cylinder to or nearly to its lower end,

as shown in Figs. 1, 2, and 3. This yoke is formed with a vertical guide-bar or extension, M, which passes between two guide-rollers, m m, as shown in Fig. 1, and it is provided with eyes at, to receive the hooked ends of connecting rods or links N, which extend thence to the inner ends of levers O O, pivoted to the arms of a cross-beam, P, extending from the post or standard F to each side of the fence, asin Fig. 1. Thelowerends of the armsoof the yoke M are furnished with studs p, which extend both inward and outward from said arms, their inner ends serving to support anti-fric tion rollers g, which traverse the helical grooves fof cylinder L and give rotary motion to the cylinder as the yoke M is raised or lowered. The outer ends of these studs carry rollers r, which bear upon and traverse the face of post F, and thereby prevent the yoke M from turning with the cylinder or twisting, as it might otherwise do.

Projecting from the side of yoke M nearest the gate is a bracket, 8, upon which is pivoted a trip or finger, t, the free end of which is normally pressed toward the face of post F by a spring, a, as best shown in Fig. 8. As the yoke is carried upward by drawing down the outer end of either lever 0, this finger engages beneath a double elbow-lever, Q, pivoted to post F, throwing its horizontal arm. upward and causing its depending arm to retract the latch or looking bolt 1), by which the gate is held shut, and the upwardly extending arm of the lever Q causes the finger t to maintain its hearing against said lever long enough to permit the gate tomove and carry the latclrbar or dog out of line with the bolt, so that when the bolt is again released it may not spring behind or against the latch-bar or dog or hinder the free movement of the gate.

'In order to prevent the finger t from encountering the upper end of lever Q during the descent of the yoke M, a pivoted guard, R, is secured to the face of post F, its upper end leaning inward against the post over the lever Q, and its lower end set away from the post, as indicated in Figs. 2, 8, and 8. As the yoke descends, the finger t rides down over the outer face of guard It, and is thereby carried clear of lever Q; but the instant it passes off the lower end ofsaid guard the finger is thrown inward again by its spring n, in position to engage the lever Q on the next upward movement of the yoke.

To permit the unlocking of the gate by hand and independently of the actuating mechanism above described, I provide the running-bar B with a pivoted gravitating latch bar, 12 Fig. 5, which in its normal position stands in front of and forms an abutment against or behind which the latch-bolt 22 may engage, as shown in Fig. 1.

The latch-bar or dog if is limited in its movements by a suitable stop-pin, '0, and is formed with an upright arm, '0, which is conneeted bya rod, 12, to ahand-lever,o", by which it may be operated from the front end of the gate. By raising the dog or latch-bar out of line with the locking-bolt v the gate may be released and made free to slide back.

Referring now to Fig. 3, it will be seen that a wheel, S, is mounted upon a horizontal shaft or axle in a recess made in the face of post F, the wheel occupying a position directly in rear of the cylinder L. The periphery or face of this wheel is grooved, as shown in Fig. 4, the groove 10 running obliquely first to the right and then to the left. In the drawings three such oblique portions are indicated on the side or face toward the observer, and these duplicated on the opposite side would give six ohlique sections, three to the right and three to the left. l

The number may be increased or diminished; but whatever number he adopted there will be formed upon the side of the cam'wheel S a ratchet-wheel, S, with precisely the same number of ratchet-teeth,coinciding in angular or circumferential position with the oblique sections of the groove 20.

The lower ends of the arms of the yoke M are connected by a hoop or ring, T, from which is suspended a pawl or dog, g which, as the yoke descends, rides'freely over one of the teeth 00 of the ratchet-wheel S, but which, as the yoke ascends, engages with the square face of such tooth and imparts to the wheel S S a partial rotation, bearing the same relation to a complete rotation that one tooth bears to the whole number of teeth in the ratchetwheel. As the cam-wheel is thus partially rotated, it gives lateral motion to a shipping lever or fork, U, one end of which is pivoted in post F, and the other end of which is seated in a circumferential groove, 2, in the collar G, en circling shaft E,'and carrying the pinions H and I, a stud, U, extending from the lever into the groove to of the cam-wheel S. This stud will preferably be furnished with an anti friction roller, though this is not essential.

It now remains only to describe the connec tion of the gate with wheel D to complete the description of the entire mechanism. This will be readily understood upon referring to Fig. 5, in which B indicates the runnenbar of the gate, and D the wheel through which the motion of shaft E is given to the gate.

V V indicate two thin flat bands, preferably of mild steel, but which may be of other metal, or of suitable alloy plated or coated to preventeorrosion, or left in its natural state. These bands each have one end made fast to the under side of the runner-bar B and the other end made fast to the wheel D, which is preferably formed with a separate groove for each band, but with a bearing-face for the bar between them. The bands are wound in reverse directions upon the wheel, and eonsequently as one winds on the other winds off; hence by rotating the wheel in one direction one band will be wound to move the gate and the other will be unwound topermitsuch movement, and preparatory to being itself wound upon the wheel to produce the return movement of the gate.

By the use of the flat metal bands I am enabled to wind them in successive layers upon themselves without appreciably increasing the diameter of the coil, and hence there is no appreciable variation in the rate at which the bands are taken up. There is consequently no necessity for making a compensating pulley, after the manner of a fusee, as would be necessary were thicker bands used, and thus wound in successive coils.

The construction being thus fully set forth, the operation of the gate may be stated as follows, assuming the parts to be in the position shown in Figs. 1 and 2, which they assume when at rest: The clutchcollar i being in engagement with pinion J, and one of the levers 0 being drawndown at its outer end to elevate the yoke M, the rollers q, rising in the groovesf of cylinder 1, give rotary motion to said cylinder in the direction indicated in Figs. 1 and 2. This rotation would be transmitted to pinion J, but for the fact that at the commencement of such rotation the stud or pin It occupies a position at the right-hand side of the opening Z, and that during the initial part of such rotation the pin is moving across the opening to its left hand wall, with which it must make contact before it can act upon the collar i. It will thus be seen that during the first part of the rise'of yoke M collar i (and consequently pinion J) remains at rest, and no motion is imparted to shaft E or wheel D. The position of finger T is such, however, thatit engages lever Q and withdraws the latch 12 at the very outset of the rise of yoke M, so that by the time the pin It comes into operative contact with the forward wall of opening'l the latch is withdrawn and the gate is made ready for movement. During this same brief period and by the same initial rise of yoke M the pawl or dog 3 engages a tooth of ratchet-wheel S and turns cam-wheel S far enough to shift lever U so as to throw collar G lengthwise of shaft E, can rying pinion H out of and pinion I into mesh with pinion J. The further elevation of yoke M,and consequent further rotation of cylinder L,gives motion,through pinions J and Lsleeve G,and shaft E, to wheel D, which, through band V, withdraws the gate. The lever O is then released aud the yoke falls to its original position, and the person or vehicle passes through the gateway. In descending, the yoke M, through its rollers q, rotates the cylinder L backward; but. this rotation is not imparted to the pinion J, because the bevel faces of teeth j cause the clutch-collar 1' to rise and its teeth to ride back over those of the pinion J, leaving the parts in the position shown in Figs. 1 and 2, except that pinions land J are then in mesh. The passenger,'having passed the gate, now pulls down upon the second lever O, and the operation above described is repeated in all particulars, except that a section of groove'w of cam-wheel S, inclined in the reverse direction from the previously-acting section, comes into play, and hence the initial portion of the rise of yoke M causes the sleeve G to be shifted in a reverse direction from the previous movement, consequently causing pinion H to go into mesh with pinion J and pinion I to go out of engagement therewith. As the pinion J rotates only in the one direction, it will be seen that when pinion H is brought into mesh with it shaft E and wheel D will be rotated in a reverse direction from that given tothem through the meshing of pinions Jand I, and hence the gate will be moved forward. Thus it will be appareutthat each alternate ascent of the yoke causes shaft E and wheel D to turn in one direction, and each intermediate ascent causes them to turn in the reverse direction, so that on approaching the gate and operating the lever at that side the gate will be opened, and on leaving itand operating the other lever the gate will be closed, and this regardless of which side is approached.
