6 Claims.
1 This invention relates to a gate of the type interposed in the length of a fence, and which is designed and adapted to be opened by contact therewith of a moving automobile or other vehicle traveling toward the gate from either side thereof.
An object of the present invention is the provision of a gate of the indicated characterwhich is longitudinally flexible so that by reason of the flexibility of the gate, the gate may beunlatched and be swung into an open position by the push of a moving vehicle, there being combined with the gate a device which delays or checks the clos ing movement of the gate long enough so that the vehicle will clear the gate on its way through the passage provided by the gate.
Another object of this invention is the provision of improvements in a gate of the indicated character by virtue of which livestock are discouraged from pushing or rubbing on the gate; and toafiord protection for a vehiclewhich might not get past the open gate due to stalling of the vehicle for any reason.
With the foregoing, other objects, benefits and advantages of the present invention will appear when the following specification is read in conjunction withthe accompanying drawings, in which:
Fig. 1 is a side view of a gate embodying the present invention, the gate being shown in closed position.
Fig. 2 is a plan view showing. the gate in closed position in full lines, and in open position in dot and dash lines, and vibration of the gate in open position is indicated in dotted lines.

Fig. 10' is a detail sectional view taken on the line-1 0 -l0 of Fig. 9.
Fig. 11 is an enlarged fragmentary sectional perspective view of the outer end portion of the gate. a
As shown in the drawings, the gate of the pres ent invention is arranged in a passage between a hinge gatepost it and a keeper gate post I i that are parts of a fence, barrier or enclosure. The posts are firmly set erect in the ground. The posts are each preferably in the form of a metal pipe, or the like, capable of withstanding con siderable twisting strain.
The gate comprises vertical inner and outer end members i2 and I3, flexible and resilient hori-- zontal members [4, and vertical pressure bars or members :5. The members i4 have their opposite ends rigidly secured to the members 52 and !3 respectively. Each of the members i2 and t3- preferably consists of a metal pipe, or the like, to withstand twisting strain. Each of the members M is preferably composed of flexible and resilient wooden boards it. Each member M is made of two boards is in the present instance, although one or more than two boards may be used; The boards secured to each other in laminated relation by aplurality of securing elements such as bolts ll. Each board it is approximately six inches wide and three-fourths of an inch thick for satisfactory results. The opposite ends of the members I4 are rigidly secured to the members i2 and [-3, respectively, and this is accomplished by the provision of a slot or slots in each member i2 and i3, and the use of securing elements, such as the bolts it, which extend through the members 1'2, 13 and M, with the ends of the members M disposed in the aforesaid slots. In the present instance use is made of two horizontal members H but more may be used if desired. The members i 5 of metal or wood are disposed at opposite sides respectively of the members [4 across the same, and are secured thereto by bolts, [9. Each member It transmits to the members It pressure exerted on the members [5 by the bumper of a moving'vehicle'. The pressure transmitted by the members It causes the members [4 to flex or how longitudinally. As a oonsequencethe gate is in fact bowed longitudinally as indicated in dotted lines in Fig. 2. A brace 20" composed of: inter 16 are laid together and the arm 24 extends horizontally.
nection with parts of the gate, namely, the upper horizontal member It, the upper end of the vertical member l3 and a lateral arm 21 formed on or secured to the upper end of the vertical member I2. The brace 20 strengthens the gate yet allows it to be flexed as stated.
The gate is mounted or hung on the post Hi for movement approximately ninety degrees between a closed position and an open position.
The gate is gravity centered to be self-closing.
In moving from the closed position into an open position, the gate swings laterally and tilts upwardly at the same time. In closing, the gate under the action of gravity tilts downwardly and swings laterally. In order to mount or hang the gate so as to move in the stated manner, there is provided means as follows. Use is made of an L shape metal bracket 22 consisting of a riser 23 and an arm 24 on the upper end of the riser 23 and extending at a right angle with respect thereto. The riser 23 is bolted to the post It so that Hinge pintles 25 and 26 are secured to the riser 23 in any suitable manner by means of lateral extensions 21 and 28 on which the pintles respectively are formed. The extension 21 of the upper pintle 25 is longer than the extension 28 of the lower pintle 26 for the purpose of alining the pintles in such manner that they provide a hinge axis A extending obliquely with respect to a vertical line. The angle of the hinge axis is such that the gate closes slowly by gravity. The vertical member it has spaced apertured lugs thereon constituting pintle eyes 28 and 29, corresponding to the pintles 25 and 26, respectively, and which receive said pintles with the eyes 28 and 29 resting on the extensions 2'! and 28 respectively. Thus the gate is mounted or hung gravity centered for movement between a closed position and an open position, the gate being self-closing. The movement of the gate from the closed into an open position is approximately ninety degrees in either direction to afliord ingress and egress.
In order to latch the gate in the closed position there is provided a Stud 35 on the vertical member 13 which cooperates with a keeper comprising a bracket 32 secured to the post H, and detents 33 on the bracket, there being a helical spring 34 interposed between and connected with said detents. The bracket 32 has a sector shape plate 35 engaged by the stud (it when the gate is in its closed position. The detents 33 encountered by the stud Sl restrain the closing movement of the gate, and enable the stud to come to rest upon the plate 35. The stud 3i resting on the plate prevents the gate from sagging while in its closed position. When pressure is exerted on one of the bars l by the pushing force of the bumper of an automobile while the gate is closed, the stud 3i will encounter one of the detents 33, as the case may be, and momentarily that detent will prevent lateral movement of the stud 3!. As a consequence, the members !4 will be flexed thereby bowing the gate and so causing the lug 3! to move endwise free of encountered detent. Then the gate swings into an open position.
In order to releasably latch the gate in its open position to delay or check the closing movement of the gate for a period of time sufficient to allow a vehicle to pass even though the vehicle is moving very slowly, there is provided a device as follows. A radius rod 36 has pivotal connection with the arm 24, as at 31, and the rod parallels the gate when the latter is in its closed position. A sleeve 38 has pivotal connection with the arm 21, as at 39. The rod 36 extends through the sleeve 38 so that the sleeve may slide back and forth on the rod, and that the sleeve may turn slightly on the rod. The sleeve 38 has a hook it on the top thereof and a projection 8| on one end at the bottom. The hook 48 viewed from the end of the sleeve is segmental in shape. The end of the sleeve 38 adjacent the projection ll is movable into contact with a stop 412 formed on the rod 36. A tubular member 43 is mounted on the top of the rod 36 for rocking or pivotal movement on a horizontal axis by means of a pivot 44 on the member 43 and an upstanding lug 45 on the rod 36. An arm 46 on the member 43 extends downwardly therefrom at the pivot 3 3. A hook 4'1 depends from the member 33 near the outer end of the latter The hook t? is similar to the hook M and cooperates therewith. A trigger rod 48 is slidable in the member 53 and has a depending lug 49 movable in a slot 9 in the tubular member 33. A helical compression spring 5%! is arranged in the member t3 between the inner end of the rod 48 and the closed end of said member 41-3. The outer end 5! of the trigger rod 33 cooperates with a notched block 52 on the top of the rod 38. The lug 59 moves adjacent the hook l'i. A helical retractile spring 53 has its opposite ends respectively connected with upstanding arms 5 and 55 on the member t3 and the rod 36 respectively. The spring 53 rocks the member 43 into an angular position when the trigger rod 48 has been moved inwardly in the member Q3, and said member 33 is held in the angular position by the spring 53, while the spring 59 holds the end 5i of the trigger rod 48 in engagement with the side of the block 52, as shown in Figs. 1, 5, 6 and 8.
When the gate has been moved into an open position in the manner heretofore explained, the parts of the delaying or checking device are in the relation shown in Figs. 4, 6 and 8. The arm 36 will have encountered the projection ll causing the member 43 to rock on the pivot M and against the action of the spring 53. The member 33 then is disposed substantially parallel to the rod 36. The end 5! of the trigger rod 48 is engaged with the top of the block 52 which holds the member 43 against return movement. At the same time the hook 67 engages the hook 40, thereby delaying or checking the closing movement of the gate. The engagement of the sleeve 33 with the stop 42 limits the opening movement of the gate and due to the flexibility of the gate the latter vibrates or oscillates as indicated in Fig. 2. This causes the sleeve 38 to move back and forth on the rod 36. As long as the sleeve reciprocates the hooks ll!) and d! cannot disengage, thereby delaying the closing movement of the gate. However, when the amplitude of the vibrations of the gate has diminished to a point where the reciprocating sleeve 38 no longer takes a full stroke and, as a consequence, the action of the sleeve no longer succeeds in rocking the trigger member 43 enough to allow the end 51 of the trigger rod 58 to engage the top of the block 52, the spring 58 rocks the member 43 into its angular releasing position. Then the gate may gravitate into the closed position in which it is latched by means of the stud 31 and detents 33 and supported by the plate 35.
A rubber pad 58 is secured around the vertical member 33 to afiord protection for a vehicle which might not get past the open gate due to stalling.
It is to be understood the invention is not restricted to the embodiment thereof illustrated and described, and that details of construction may be modified and rearranged in accordance with the scope of the invention as defined in the appended claims.
