Application filed April as, 1922. Serial no. 556,694.

To all whom it may concern:

Be it known that l, AUs'rrN F1. MILLER, a citizen of the United States, residing at Cheney, in the county of Spokane and State of Washington, have invented a new and useful Gate, of whichthe following is a specification. i

This invention aims to provide novel means for operating a gate from a remote point. Another object of the invention is to provide novel means for latching the gate.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention. shown can be made without departing from the spirit of the invention In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention; Figure 2 is a section on the line 22 of Figure 1; Figure 3 is an elevation disclosing one of the supports and attendant parts; Figure is a sectional detail illustrating the latch mechanism; Figure 5 is a sectional elevation wherein the structure shown in Figure 4: is viewed at right angles to the showing of that figure; Figure 6 is a sec tional elevation showing the gate in closed position; Figure 7 is a horizontal section taken through one of the supports; Figure 8 is a fragmental elevation showing a modification; and Figure 9 is a top plan of the structure delineated in Figure 8; Figure 10 is a sectional view showing a modifiedforin of the invention.

In carrying out the invention, there is provided a frame 1 including a track 2. A guard 3 is located above the track 2 and includes end portions 5 attached by securing elements 6 to the frame 1. The numeral 1 designates a gate, mounted at 7, preferably through the instrumentality of rollers, to move along the track 2. The gate 1 is provided at one end with a keeper 8, adapted to be received in a. seat or opening 9 formed in one end portion of the frame 1, so as to prevent the gate from swinging outwardly with respect to the frame 1, when the isin a closed position.

Supports 10 are located at any desired distance from the frame 1. A shaft 11 is mounted for rocking movement in the supports 10 and in the track 2. Angle braclrets 12 are provided, each angle bracket including an arm 1 1 secured to one of the supports 10, and an arm 1,.) extended parallel to the shaft 11, the shaft 11 being journaled in the arms 1a ofthe angle brackets 12. Pinions 16 are secured to the shaft 11 outwardly of the supports 10 and the arms 1st of the angle brackets 12, as shown in Figure 7. Segments 17 are mounted at 18 to swing vertically on the arms of the anglebrackets 12. Each segment 17 has a depending arm 19 carrying a handle 20, the handle preferably being pivoted at 21 to the arm, so as to hang in a depending position when not in'use, as indicated in Figure 1, the construction being such that animals cannot rub' against the handles and operate the gate. Each segment 17 includes a lateral rack 22 meshingwith one of the pinions 16 on the shaft 11.

c A' pinion or segment 23 is carried ,by the shaft 11 and is located adjacent to the gate 4. The shaft 11 has a limited amount of rotation. in the pinion or segment 23. The pinion or segment 23 meshes with a rack 24lconstituting part of the gate 41. 1%, latch 25 is pivoted at 26 to the hub of the pinion 23. A bow-ed spring 27 is secured at 28 adjacent to one end, to the latch 25, the other end of the spring bearing against astop 29 on the hub of the pinion 23. The spring 27 tends to swing the free end of the latch 25 downwardly, so thatthe latch Wlll engage with a keeper 30 projecting laterally from the gate 4. Acam or arm 31' is secured to the shaft 11 and is adapted to cooperate with thelatch 25 and with the stop 29 in a way which will be pointed out hereinafter.

In practical operation, the segments 17 may he swung. on theirpivotal mountings 18, through the instrumentality of the arms 19 and the handles 20, rotation being imparted to the shaft 11 through the racks 22 on the segments 17 and the pinions 16 on the shaft 11.

- Passing to Figure. 1, suppose that the latch 25 on thesegment 23 is engaged with the keeper 30 on the .4. The shaft 11 rotates to a slight extent, independently of the segn'ient 23 and during this independent rotation of the shaft, the latch is disengaged from the keeper 30, and is moved to the dotted line position of Figure 4, the gate 4. thus being set free. YV hen continued rotation is imparted to the shaft 11, the arm 31 on the shaft, having disengaged the latch :25 from the zeeper 80, imparts rotation to the segment 23, by way of the latch 25, and when the segment 23 is rotated, the segment, cooperatingwith the rack" 24: on the gate 4, slides the gate 4t from the closed position of Figure '2 to the right, into an open position. lVhen reverserotation'is imparted to the shaft 11, the gate is carried back into the closed position of Figure 2 and the latch 25' engages automatically with the keeper 30, as shown in Figures 2 and 4L.

It will be understood that any suitable means may be provided for imparting rotation to the shaft'll, the structure shown in Figure l being retained In Figures 8 and 9, parts hereinbeforedescribed have been designated by" numerals previously used, witli'thesuflix a. The shaft 11 is made much shorter than the shaft 11,,the supports 10 and cooperating parts being dispensed with, the shaft 11 being journalled in a side bearing 82 on the track 2. 'The shaft 11 carries a gear wheel or segment 33, meshing with a pinion 34: on the shaft of an electric motor 35, mounted on one side of the track 2, or elsewhere. Conductors 36 of any desired length, lead from the motor 35, switches 37 being interposed in the conductors. I V

Obviously, by operating the switches 37, the motor may be put into operation, the pinion cooperating with the gear' wheel or segment 33 to impart rotation to the shaft 11, the gate being opened and closed through the instrumentality of the mechanism hereinbefore described.

:lleverting to Figured of the drawings, it will be understood that when the shaft 11 is-rotated clockwise, the arm or cam member 31, coacting with the stop 29 imparts rotation to the pinion 23, the pinion coacting with the rack 24 tomove the gated to the closed position shown in Figure 2 of the drawings. v i

In Figure 10, the numeral denotes a support,- made of concrete, or otherwise, and provided with a slot 51. A lcver' 521s located in the slot 51 and is fulcrumed at one-end, as shown at 53 on the support 50. A switch 54: is disposed beneath the lever 52. roller 55, is journaled on'th lever 52.

The free end of the lever 52 is pressed upwardly by a spring 5Ganterposed between the lever and the support 50. The roller 55 projects slightly above the surface of the' highway indicated at 57. A vehicle traversing the highway will pass over the roller 55, depress the lever 52, close the switch and operate the date through the instrumentality o T he mechanism shown in Figures 8 and 9.
