OPENER FOR GATES.

Specification of Letters Patent.

Patented Nov. 28, 1916.

Application filed February 10, 1916. Serial No. 77,459.

To all whom it may concern Be it known that I, MARTIN S. HAMMER, a citizen of the United States, residing at Modesto, in the county of Stanislaus and State of California, have invented certain new and useful Improvements in Openers for Gates; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to gates, and more particularly to openers therefor.

The primary object of the invention is to provide a swinging gate adapted to be unlatched, opened, maintained in its open position, and closed, without the necessity of dismounting from a horse or leaving a vehicle.

Another object of the invention is to provide a device of this character which will be simple, strong, durable, and inexpensive in construction, efiicient and reliable in operation, and well adapted to the purpose for which it is designed.

Other objects and uses will appear from the detailed description of the invention which consists in the features of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings in which similar reference characters designate like parts throughout the several views, Figure 1 is a perspective view of a gate constructed in accordance with this invention; Fig. 2 is a side elevation of the upper pivot mechanism of the gate; Fig. 3 is a top plan view of the upper pivot mechanism of the gate; Fig. 4 is a vertical sectional view taken through a portion of the gate showing the lower pivot; and Fig. 5 is a horizontal sectional view taken on the line 55 of Fig. 1.

Referring more particularly to the drawings, the reference characterl designates a fence post to which is hinged in a manner hereinafter to be described a gate 2. This gate 2 may be of any convenient construction, but is here shown as being formed of a pair of substantially upright end bars 3 be tween which are disposed parallel longi-' tudinal bars 4. The inner end of the gate is cut ofi' angularly and the inner end bar 3 is extended upwardly above the plane of the .uppermost longitudinal bar 4:-

Secured in any suitable manner to the lower end of the inner end her 3 is a cap member 5, from the lower face of which extends a pivot stud 6. This pivot stud 6 is received in a suitable recess 7 arranged in the upper face of a metal plate 8, the latter being secured to a suitableblock 9 fastened to the lower end of the fence post 1. This mechanism comprises the lowerfixed pivot of the gate.

Arranged adjacent the upper inner end of the gate 2 and adjacent the upper end of the inner end bar 3 is a guide in the form of .a segmental plate 10, the rear end of whichis provided with a downwardly extending portion 11, the latter being firmly secured to the fence post 1 by suitable screws or bolts 12. Pivoted at a point in vertical alinement with the lower fixed pivot of the gate 2 by a pivot bolt 13, is a U-shaped link member 14, the two arms 15 of which are disposed on opposite sides of the plate 10. The outer ends of the arms 15 are provided with alined bearings 16 in which is revolubly mounted a shaft 17 and fixed to the shaft 17 between the arms 15 is a pinion 18, the latter engaging a rack 19 arranged on the arcuate edge of the plate 10. The lower end of the shaft 17 is extended into a recess 20 arranged in the upper end of the inner end bar 3, a metal cap member 21 having an' aperture 22 in the upper face thereof being disposed over the end of the end bar 3 to prevent wearing of the recess 20.

Clamped between a suitable stop member 22 and a nut member 23 secured on the threaded upper end of the shaft 17, is a double pulley '24 around which'are wound suitable ropes 25 and 26. These ropes are carried down the road on either side of the gate 2 and are run over suitable pulleys 27 secured to arms 28 arranged at the upper ends of posts 29. The free'ends of the ropes 25 and 26 are provided with handle members 30,.which are preferably made of metal or some heavy material to cause the former to remain substantially in an upright position.

The outer end bar 3 of the gate is provided with a lug 31 which engages a resilient latch In order to c 3611 the ate 2 it is necessar 19, thus moving the upper inner end of the gate concentrically around the lower fixed pivot thereof in a planeabove the same and in advance of the other portion of the gate. As may be readily understood, the gate is tilted in the direction toward which the pinion is moved, or inother words, overbalanced, and it then swings into opened position by force of gravity. Loose movement between the pivot stud 6 and the shaft 17 is accomplished by having their sockets larger than is ordinarily necessary. 7 i

To close the gate, the short rope at the other side thereof is pulled downwardly, and in which event the movement of the pulley 2i and the pinion 18 is reversed, thereby causing the gate to swing into its closed position by force of gravity. It is to.

be uncerstood that in both the opening and closing movement of the gate, the lug 31 carried at the outer end thereof passes beyond the resilient arms of the latch 32.

From the foregoing description, taken in connection with the. accompanying drawings, the operation of the invention willbe fully understood without a more extended explanation.

its various changes in form and proportion may be resorted to without departing from the spirit of this invention, 1 do not wish to be limited to the construction here? in described and shown other than that set forthin the appended claims.

I claim:

1. In a device of the character described, the combination of a normally balanced swinging gate, a pinion rotatably mounted at the upper inner end of said gate, astationary rack guide supported adjacentsaid gate and positioned for engagement, with said pinion, and means for rotating said. pinion, whereby'to tilt said gate.

2. In a device of the "character described. the combination of a normally balanced swinging gate, a. segmental rack arranged adjacent the upper end of: said gate, a pivotally mounted member connected to the upper inner end of said gate, a pinion mounted on said member and engaging said rack, andmeans for rotating said pinion for Copies of this patent may be obtained for five cents each, by addressing the Commissioner, of. latents,

' \v. moving tile-11131362111118? end of said gate,

whereby to tilt the latter.

upper inner end of said gate, a rack arranged on the arcuate edge of said plate, a pinion fixed to said shaft and engaging said rack, and means for rotating said pinion for moving the upper inner end of said gate 7 around said rack whereby to tilt said gate,

4:. In a device of the character described, the combination of a normally balanced swinging gate, segmental plate arranged adjacent the upper inner end of said gate, a'

U-shaped link member pivoted to said plate, the arms of said member being spaced and disposed on opposite sides of said plate, a shaft mounted on the outer ends of said arms and loosely connected to the upper inner end of said gate, a rack arranged on the arcuate edge of said plate, a pinion fixed to said shaft and engaging said rack, a pulley fixed to said shaft, and means for rotating said pulley for moving the upper inner end of said gate around said rack, whereby totilt said gate.

5. 111 a device of the class described, the combination with a normally balanced swinging gate having a recess in its upper inner endand'a pivot studat'its lower inner end, a supporting plate arranged below the lower inner end of said gate and having a recess therein for receiving said stud, a segmental, rack supported adjacent the upper inner end of said gate, an upright shaft rotatably supported adjacent the last referredvto end of said gate and having a pinion fixed thereon for engagement with said rack, the lower end of said shaft being loosely received in the recess in the upper inner end of saidgate, and means for rotating said shaft whereby to tilt said gate.

In testimony whereof I have hereunto set my hand. in presence of two subscribing Witnesses. I
