AU'IQMATIG GATE.

Application filed November To all whom it may concern:

Bev it known that I, Josnri-r R. VVALLAGE, a citizen of the United States, residing at San Angelo, in the county of Tom Green and State of Texas, have invented certain new and useful Improvements in Auton'iatic Gates, of which the following is a specification.

The present invention consists of an auto 1 maticgate foruse in practically any capacity in which a gate now serves, in addition vention is such as to permit use ofthe same as a door for garages or thelike.

An object of the invention is to provide a device of this character which is simple in construction yet durable to permit the gate to be swung on its axis by the impinge-' ment of an object therewith without mutilating or otherwise damaging either the gate or the object.

Other objects of the invention will be ap-,

parent from the following description of the presentpreferred form of the invention taken in connection with the'accompanying drawings wherein Fig. 1 is an elevationalviewof a gate constructed in accordance with this invention illustrating its application Fig. 2 is a vertical sectional view of the same; and

Fig. 3 is an elevational view of a slightly modified form of gate.

In the form of invention shown in Fig.1 1 of the drawings, aportion of a fence 1- is" illustrated in order to show the relative position of the gate therein. By preference, a base supporting frame5 is countersunk in the earth transversely between the fence posts. v

The form of gate shown inFig. 1 consists of a substantially rectangular structure 6 preferably formed from pipes the ends of which are screwthreaded as indicated at 7 for engagement in complemental .threads formed in elbows 8. A retieul'ate structure such as indicated at 9 may be mounted in the frame Galthough if desired this maybe modified or completely omitted depending upon the use Whichthegate is intended to serve. The frame is. equipped on one side with apair of strips 10 made of wood, metal or other suitable material, one strip being 3,1922. Serial No. 672,536.

mounted adjacent each end of the gate and secured to the frame. The strips extend transversely across the frame and are positioned so as to lie beyond the base 5 so that when the gate is in a horizontal position these strips will serve as runways or traction strips for a vehicle moving over the gate. The lower portion of the gate frame is movably mountedbetween loop straps ll carried by the upper marginal edges of the base 5. The gate is normally held in a ver tical position by means 12 which in the present instance consists of a helical spring mounted on each side of the gate oneend thereof being secured to the lower end of the gateyas indicated at 13, while the opposite end is engaged with a chain 14 secured to the base 5. I

It is apparent that when an object, such for instance as a motor vehicle impinges the gate that the latterwill move downwardly against the resistance of the springs 12 per mitting the vehicle to ride over the strips plane by the action of the springs 12.

In the form ofinvention shown in Fig. 3 of the drawings, a base frame 5 is provided which is relatively longer thanthe frame 5 and is also countersunk in the earth. The gate shown in Fig. 3 consists of a frame formed from a single strand of wire 6f which may be bent into rectangular shape and has one end thereof formed to provide an eye 15 through which the opposite end of the strand extends to provide a shank 16. This shank is adapted to depend in the base frame 5 and has its lower end formed to provide an eye 17 which carries a weight 18. The gate frame is pivotally mounted on the base 5 beneath loop straps 11. Runways or treads 10 may be secured to one side of the gate frame'for use in the same manner as the runways 10 shown in Fig. 1.

In use of the form of invention shown in Fig. 3 it is apparent that impingement of an object with the gate will urge the latter into a horizontal position thereby elevating the weight 18. As soon as pressure It is of course to be understood that various changes maybe made in the device mounted gate franle composed of a single of this invention especially in the details of strand of Wire one end of which depends construct-ion, proportion and arrangement below the plane of the gate frame and is 10 f -t ithi th Scope f th clai nghe teequipped with a Weight to normally hold 5 to appended. the gate in a vertical position.
