The present invention is directed to im- P1OYC111G11tS in gates.

The primary object of the invention is to provide a gate so constructed that a vehicle approaching the same will. cause the gate to open and permit the vehicle to pass, after which the vehicle will operate means to release the gate to permit the same to swing to its closed position.

Another object of the invention is to provide a gate so constructed that an approaching vehicle will operate to el .val'e the gate as it swings open, means being provided to hold the gate open until the vehicle passes through the gate opening, the holding means being releasable by the vehicle to permit the gate to swing closed by gravity.

Another object of the invention is to provide a gate of this type wherein the operating mechanism is simple in construction, durable, and can be produced at a very small cost.

li ith these and other objects in view, this invention resides in the novel features of 35 construction, :liormation, combination and arangeiuent of parts to be hereinafter more je ly described, claimed and illustrated in the accmupanying drawings, in which Figure 1 i a perspective view showing the gate in its closed position.

covered by a platform 5, the walls of the pit being preferably formed from cement.

Mounted upon the platform 5 adjacent the post 1 is a collar 6 which coincides with the opening 7 formed in the platform, said collar having formed interiorly thereof diametrically opposed inclined tracks 8, the upper ends of whic h terminate in vertical tracks 9,

the purpose of which will appear later. The gate 10 comprises tubular posts 11 and 12 which are connected by bars 13, the former post forming the pivotal mounting for the gate 10.

The post 1 1 has a spindle 14 carried by its upper end for rotatably engaging the bearin g bracket 15 mounted upon the post 1.

F ixed in the lower end of the post 11 is a plug 16 in which is mounted a transverse shaft 17 upon the ends of which are mounted rollers 18*18 adapted to engage the tracks 8 and 9 of the collar 6. The plug has an axial opening 19 in which is slidable the rod 20, said rod having its lower end extending gagement with the plate 3.

The latch rod 25 has a handle 26 thereon to permit the same to be manually operated, there being a spring 27 engaged upon the rod for normally urging the rod forwardly for engagement with the plate 3.

Supported between the walls 2828 of the pit 4: ar

e shafts 29 and 30, which pivotally support levers 31. and 32, respectively.

Between the walls 3333 and 3t-3-il of the pit are mounted shafts 35 and 36 to which are pivotally connected the outer ends of the trip bars 37 and 38, respectively. The free end of the bar 37 rests upon the lever 31, while the free end of the bar 38 rests upon the lever 32 as clearly shown F are arranged in overlapping relation, the overlapped portions being located under the lower end of the rod 20 in order that when the lovers 31 and 32 are rocked in one direction the rod 20 will be moved upwardly to actuate the latch rod 25.

The levers 37 and 38 have carried thereby heads 39 and l0, which are arranged to normally extend above the plane of the platform 5, said platform having openings .ll 41 to permit full depression of the heads when. encountered by a wheel of a vehicle. These heads are capable of being removed when desired.

A rock shaft 42 is journaled between the walls 13 13 of the pit l and have arms 1 1 and 15 carried by its ends, said arms having heads 16 and 47 carried by their ends. This shaft provided with a lever 4-8 which operates between the walls 4l9-el9 of the pit. The lever 18 has its inner end engaged with the book 50 formed upon the lower end ot the link 51, said link passing through the plati'orm 5 and has its upper end pivoted to the bar 52 which is pivotally connected to the post 53. The post 53 is placed in longitudinal alinement with the main post 1 and is spaced therefrom a distance approximately the length of the gate 10. The bar 52 has carried thereby a lug 5a for engagement with the free end of the gate when in its open position. Encircling the lin 51 and interposed between the bar 52 and platform 5 is a coil spring 55 which serves to normally hold the bar in a horizontal position.

End posts 56 and 57 are employed and rotatably supported by these posts as well as by the posts 1 and 53, is a rock shaft 58, the outer ends of which carry arms 59 and (30, there being an intermediate arm 61 fried to said shaft. The arm (31 is pivotally connected to the mljaeent end of the bar 52 by a link (32 in order that when the shaft is rocked the bar 52 will be likewise rocked. Flexibly connected to the arms 59 and are hand rings 63 and (jet, respectively.

The posts 56 and 57 have pivotally connected thereto levers 65 and '66, respectively, said levers having flexibly connected. thercto hand rings (37 and 68. The lever (35 has pivotally connected thereto the upper end of a rod 69 which passes through the platform 5 and has its lower end connected to the outer end of the lever 31. A red 70 is similarly connected to the lever (55 and has its lower end connected to the outer end of the lever 32. As shown in Figure 1 the 10 is in its closed position. When a vehicle approaches the gate a front wheel thereof is guided upon the head 39 to depress the same, whereupon the trip bar 37 will swing downwardly thus rocking the lever 31. As the lever 31 rocks the inner end thereof will force the rod 20 upwardly, thus rocking the lever 24: to withdraw the latch rod 25 from engagement with the plate As the lever 31 moves upwardly it will engage the lug 21 thus forcing the post 11 upwardly, and during this upward movement the post will rotate due to the engagement of the rollers 18 in the track 8, thus swinging the gate 10. As the gate continues to rotate the rollers will rise into and upwardly in the vertical tracks 9 until the lever 31 has been rocked to its fullest extent, and the gate fully opened. It will be of course understood that as the gate swings open it will also move upwardly so that the post 12 rides upon the bar 52 for contact with the lug 54. the spring 55 will hold the bar 52 yieldably eng red with the gate to maintain the same op .n.

The gate now being open the vehicle passes through the gate opening and is guided so that front wheel engages the head &7, which rocks the shaft 42 and thus the lever 18, which pulls downwardly upon the link 51, thus rocking the bar 52, whereupon the post 12 is forced from the bar 52 by the lug 5 1 and the gate will close by gravity. It will be of course apparent that when a vehicle approaches the gate in an opposite direction the head 10 will be encountered first to rock the lever 32 through the means of the bar 38. hen the head 16 is depressed it rocks the shaft 42 to release the gate to permit the same to gravitate to its closed position.

ln localities where snow remains a very long period, I have found it desirable to re move the heads '39, 40, 16 and -17 and in which instance the gate isopened and closed through the medium of the rings 63, 64:, 67 and 68. To open the gate through the medium of the rings it will be obvious that when the ring 67 is pulled downwardly that the rod 69 will actuate the lever to elevate the gate and swing the same to its closed position, the ring (38 being actuated when it is desired to open the gate from a reverse direction. Since the rings (33 and 6% control the movement of the bar 52 it will be obvious that upon operating these levers the bar will be manipulated to permit the gate to gravitate to its closed position.

From. the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled. in the art, without furtherdescription, and it will be understood that various changes in the size, shape, and proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the. invention.

lVhat is claimed is 1. The combination with a collar, of a gate having a post engaged in the collar, a latch rod carried by the gate, means operable first to actuate the latch rod to release the gate and then elevate the post to swing the gate open, means for holding the gate open, and

means for releasing the holding means to permit the post to slide downwardly in the collar to close the gate.

2. The combination with a collar having inclined tracks therein, 01 a gate having a post engaged in the collar, rollers carried by the post for movement in the tracks, levers operable when subjected to pressure for moving the post upward to cause the rollers to travel upward in the tracks to impart rotary movement to gate to swing the same open, and means for releasing the holding means to permit the rollers to travel downwardly in the tracks to swing the gate closed.
