Leake, Middletown, Va.; The First National Bank of Strashurg, Virginia, administrator of said Arthur G. Leake, deceased, assignor to Marion B. Leake, Warren County, Va.
Application January 14, 1949, Serial No. 70,831
25 Claims. (Cl. 39-31) This invention relates to improvements in automatic gates, and has to do, more particularly, with a swinging gate which is adapted to be opened automatically by the impact of a motor vehicle and then automatically closed after the vehicle has passed through the gate opening.
One object of the invention is to provide a swinging gate, sunple in construction but efiicient in operation, which will be unlatched and swung open automatically by horizontal pressure applied thereto, as by a slowly moving motor vehicle, without the necessity of the driver leaving the vehicle to unlatch the gate.
Another object of the invention is to provide a swinging gate which will automatically return to latched position after the vehicle has passed through the gate opening.
Another object of the invention is to provide an automatic gate of such nature that pressure, applied thereto to open it, will lift both the hinged end and the free end of the gate.
Further objects, and objects relating to details of construction and economies of operation, will definitely appear from the detailed description to follow. My invention is clearly defined and pointed out in the appended claims. A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of the specification, in which:
Fig. l is an elevation view of the gate and gate posts, showing the general arrangement of parts.
Fig. 2 is an enlarged sectional view, taken on the line 22 of Fig. 1, showing, in full lines, the gate in closed position, and, in phantom lines, parts of the gate in open position.
Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2, showing also, in phantom lines, several positions the gate may occupy when swung from latched position.
Fig. 4 is a sectional view, taken on the line 4--4 of Pi 3.
l ig. 5 is an enlarged detail view showing the latch pin secured to the framework of the gate.
Fig. 6 is an enlarged view in side elevation of the latch unit secured to the gate post, the position of the latch pin, as the gate is being closed, being shown in phantom.
Fig. 7 is an enlarged view in side elevation of the latch unit, showing the position of the latch pin as the gate approaches latched position.
Fig. 8 is an enlarged view in side elevation of the latch unit, showing the latch pin in one position it occupies as the gate is being opened by horizontal pressure.
Fig. 9 is an enlarged view in side elevation of the latch unit showing the latch pin in another position it occupies when the gate has swung open far enough for the pin to pass the pivot point and to start its descent on the opposite end of the keeper.
Fig. 10 is a view in side elevatlon of the latch unit with the latch pin in latching position and the keepers locked against movement, and
Fig. 11 is a sectional view taken on the line 1111 of Fig. 10.
In the drawings, the same reference numerals refer to the same parts throughout the several views, and the sectional views are taken looking in the direction of the arrow at the end of the section line.
In general, the automatic gate of my invention comprises a pair of gate posts spaced to provide an opening between them, a gate adapted to close that opening, means for mounting the gate on one of the two posts so that it may swing aoout a vertical axis and move vertically with respect to that post, means on the said post and the gate which cooperate to lift the gate as it swings from closed position, and latching means that are mounted on the other post and the gate and cooperate to latch the gate in closed position, and which are effective, when horizontal pressure is applied to the gate to open it, to lift the gate as it swings from latched to unlatched position. The latching means may include a latch pin fixed on the free end of the gate and a latch unit mounted on the adjacent post, and this latch unit may comprise a plate having a horizontal ledge, on which the latch pin rests when the gate is closed, and a keeper pivotally mounted on the plate with the inner end thereof normally engaging the ledge at one side of the latch pin. Preferably, the keeper is pivoted to one side of its center of mass, so that gravity tends to hold the inner end thereof in engagement with the ledge, and the upper face of this keeper is inclined upwardly and outwardly so that it forms a ramp, up which the latch pin rides as the gate is forced to unlatched position. In order that the latch unit may be effective to permit automatic opening of the gate, by pressure applied to it in either direction, the latch unit preferably includes a pair of keepers pivoted on spaced horizontal axes with their inner ends normally engaging the ledge, one on either side of the latch pin, when the gate is closed. The upper faces of these keepers are inclined upwardly and outwardly, forming oppositely inclined ramps, and, when pressure is applied to the gate to open it, the latch pin rides up and over one of these ramps, lifting the gate at the same time, the ramp which is effective being determined, of course, by the direction in which the pressure is applied to-move the gate. The outer ends of the keepers are normally spaced from the ledge so that, as the gate swings to the latched position, the latch pin may move on the ledge beneath one of the keepers, lifting it until latched position is reached, at which time the keeper drops down behind the pin. Stops on the latch plate are preferably provided to limit movement of the inner ends of the keepers away from the ledge, so that they will not be thrown into inoperative position by the pressure of the latch pin as the gate is opened. I propose to provide a removable locking insert that may be positioned between the stops and the inner ends of the keepers, so as to block the pin against movement over either of these ramps to unlatched position.
The means, at the hinged end of the gate, for lifting it as it swings open, may include an arcuate cam track fixed to the adjacent gate post and a roller fixed to the gate and rolling on said track. The cam track is provided with a low point, which is in line with the two gate posts, and the roller engages this low spot when the gate is closed, but, as the gate is swung in either direction from closed position, the action of the roller on the inclined track raises the gate. This roller may take the form of a ball slidably mounted on a horizontal rod fixed to the gate, and the arcuate track may be so formed that it approaches the axis about which the gate is hinged, as one proceeds from the low spot toward either of the high spots, with the result that the ball must slide on the rod to follow the trackway as the gate is opened. This provides friction which is effective to retard the opening of the gate, and also gives a slight delay before the gate begins to swing shut under the force of gravity.
A pair of gate posts 10 and 11 (Fig. 1) are spaced apart to provide an opening of desired width, to be closed by a swinging gate 12. One end of the gate is hinged to post 10 by an upper hinge bracket 13 and a lower hinge bracket 14, both of which are secured to the post 10 by suitable fastening means, such as screws 15. The opposite or free end of the gate is provided with the hereinafter described latch unit, which is mounted on post 11. Gate 12 may be of any construction, but is advantageously of the so-called non-sagging type, having a framework comprising an upper U-shaped frame 16 and a horizontal lower rail 17, joined at their ends by brackets 18 and 18a. Any number of upright bars 19 may be vertically disposed at intervals longitudinally between the frame members 16 and 17, with their ends secured to the frames by brackets 21. One leg of frame member 16 is journaled in hinge brackets 13 and 14 to hinge the gate. Wire fencing 22 is stretched taut and fastened to the framework by means of hanger wire 23. A pair of heavy strips or boards 24 of any suitable material, preferably relatively thick wood planking, are secured near the bottom of the gate, one strip on one side and the other on the other side of the gate, at the height of the bumper on a motor vehicle. These strips are of substantial length, and attached to the framework by any suitable fastening means, such as bolts 25, which clamp them securely to the gate frame.
The lower hinge bracket 14 has an extension 31 integral therewith and secured thereby to post 10. The extension, however, might be separately formed and secured to the post. The extension has an arcuate inclined track 33, which extends from a high point 34 on one side of the post to a similar high point 35 on the opposite side of the post, the track sloping from these two high points to a medial low point 36 on the line between the two posts.
The track will be long enough to permit the gate to be swung in either direction, far enough for a motor vehicle to clear it in the brief space of time necessary to pass through the-gate opening. Ordinarily, the track will c'omprise about three-fifths or more of a complete circle to allow the gate to swing through an arc of about 210.
The bracket 18 comprises two half sections 40 and 41, held together by bolts 42, and has a pair of spaced extensions 43 for mounting a rod 45 on which a roller ball 46 is rotatably positioned. The roller ball runs in a groove 47 on the track member 33, and the groove is of a conformation to retain the roller in it and guide the same along the trackway. The roller is loosely mounted on the rod 45, and axially movable thereon between the extensions, so as to align itself with the track and follow the groove when the gate is opened or closed. The
,iportion of the track adjacent the low point 36 is substantially concentric with the vertical axis about which the gate swings, but as one approaches the high point of the track, in either direction, the track gradually approaches said vertical axis. Consequently, as the gate swings open, ball 46 in following the track must slide on red 45, and the same action occurs when the gate closes. Recesses or sockets 37, of slight depth, are provided at the high ends of the track, which receive ball 46 to retain the gate in wide open position. As the gate is swung open, the roller rides on the'track 33 from the low point 36 to either of the high points 34 or 35,, depending in which direction the gate is opened. As the roller moves from the low point to 'one of the higher points on the track, the gate will be lifted and frame member 16 will slide vertically in the hinge brackets 13 and 14. After being opened the desired distance, the inclined track will automatically cause the gate toswing shut by gravity. The latch, hereinafter described, on the opposite post is of a construction to lift initially the free end of the gate and release 'it from latched position when the gate starts to open, and to automatically latch the gate when it swings shut.
A latch unit, generally designated by numeral 48, is
mounted on the post 11 by screws 49, projecting through slots 50,so that the latch unit'may be adjusted in proper position for cooperation with the latch pin on the free end of the gate. The latch unit comprises a plate 51 having a vertical wall, in which the slots 50 are formed,
and a horizontal ledge 53 extending laterally therefrom, the ends of "the ledge being curved downwardly, at 61 and 62. A pair of keepers, 54 and 55, are pivotally mounted on pins'56, threaded into the bosses 57 formed on the plate 51. The two keepers are disposed parallel to the plate 51 with their adjacent ends spaced apart. A projecting latch pin 52 fixed on the free end'of the gate is lodged in the space between the keepers, when the gate is latched, and said keepers provide ramps for lifting the gate when it is to be opened. Each keeper is pivoted to one side of its center of mass, so that their adjacent inclined ends drop by gravity into contact 'with ledge 53. Stops "58 and 590m the vertical wall of the "plate 51 limit the pivotal movement of the keepers 54 of the gate, and for supporting the adjacent ends of the keepers, which are normally in contact therewith. The
projecting latch pin 52 between the keepers.
keepers 54 and 55 are disposed with their ends 64 and 65 adjacent, and their opposite ends 67 and 68 normally lifted above the ledge. The latch pin 52 is lodged on ledge 53 between adjacent ends, 64 and 65, of the keepers, when the gate is latched in closed position. The inclined top surface of each of the keepers provides a ramp for the projectinglatch pin 52 on the free end of the gate.- When horizontal pressure is applied to open the gate, said latch pin moves up the ramp formedby one of the keepers, 'until it passes beyond the pivot point thereof and is eased oif the opposite end. Thus, the gate is lifted as it is unlatched. When the gate swings shut, the latch pin 52 moves onto the ledge '53 and beneath the corresponding keeper lifting the inner end thereof until the pin engages the inner end of the other keeper, when the first-mentioned keeper falls .into place behind the pin, as shown in Fig. 10.
A locking insert may be provided to prevent the gate from being opened until after the insert has been removed. The insert, preferably secured-to the post l'i by chain 69, has-atop neck portion 70 adapted -to fit between the two stops, 58 and 59, on the plate 51 of the latch unit .and a bottom portion 71 conforming generally to the contour of the ends ofthe adjacent keepers, 54 and '55, except for a recess 72 provided therein to receive the latch pin 52 on the gate. Shoulders 73, adjacent the neck portion 70, abut the bottoms of the two stops, and the bottom portion 71 of the locking insert seats upon the adjacent ends of the keepers and over Ilthe T us, horizontal pressure will be ineifective to cause 'pin 52 to .ride upeither of the keepers.
From the foregoing description, the operation of'the automatic gate to open .or closed position is obvious. As the bumper of a moving vehicle comes into contact with one of the bumper boards '24 on the gate with slight impact, the latch pin 52 on the free end of the gate is forced up the inclined top surface of one of the keepers, this being illustrated in the drawings as keeper 54 (Fig. 8), and past the pivot point thereof, to then ride down and off the opposite end 67 of said keeper. The gate is lifted and the weight of the gate on the 'keeperend 67 causes keeper 54 to pivoton .pin 56 until the upper surface of the opposite end contacts stop 58 '(Fig. '9'). The keeper will remain in that position until the latch pin rides oif end 67. As thelatch pin leaves the keeper, the gate drops until ball 46 at the hinged end engages track 47, but the elevation of the free end of the gate in being unlatched relieves the friction at the hinged end of the gate, so that it starts to swing open more easily. As the gate 12 swings further, after being since the ball, as it follows the track, has to slide on the supporting rod. 'By the time the ball has reached one of the high points of -the track, in opening, the vehicle has had time to pass completely through between the posts '10 and 11 and clear the gate. The gate, then, will swing closed 'by gravity, the ball 46 rolling down the inclined trackway toward the low point. As the gate nears closed position, the latch pin '52 on the free end of the gate rides on the ledge 53 of the plate SL-beneaththe keeper-54 (Fig. 6), passes between the ledge and pivot 56, lifts the inner-end of the keeper rocking it clockwise on its pivot and continues along the -ledge until it engages the inner end of keeper '55 (Fig. 10), when the lifted keeper 54 will drop behind the latch'pin to retain the gate in latched position. The inclination of the sloping track 33 is such that it 'allows the gate to drop, as it swings to closed position, sufliciently so that the latch pin 52 is presented approximately in line with l'edge'53, so that it may move thereon in the final stage of the closing movement.
The gate may be opened in the opposite direction by pressure applied by a vehicle moving against 'the'bumper plank 24, on the other side of the gate, causing the latch ,pin 5210 ride up over keeper '55 and return to latched position beneath the same when the gate is closed. A latch construction has been shown with two keepers, so that the gate may be swung open from either of two directions, but it will be understoodtnat a latch with only one keeper could be employed, if it were desired to have the gate open in but one direction. Any stop means could be used in lieu of one of the keepers as a stop for the latch pin 52.
I am aware that the apparatus shown and described herein is susceptible of considerable variation, without departing from the spirit of my invention, and, therefore, I claim my invention broadly as indicated by the appended claims.
