HERMAN H. DEUTSCHEBI, OF CABBOLLTON, MISSOURI.
FARM-GATE.
Application filed February 6, 1911.
To all whom it may concern:
Be it known that I, HERMAN H. DEUTSOHER, a citizen of the United States, residing at Garrollton, in the county of Carroll and State of Missouri, have invented certain new and useful Improvements in Farm- Gates, of which the following is a specification.
My invention relates to improvements in farm gates.
The object of my invention is to provlde a simple, efficient and durable farm gate, which may be automatically opened and closed by a wagon, sled, or other vehicle moving past the gate in either direction.
A further object of my invention is to provide a gate with mechanism for looking it in the closed position and with means by which a vehicle moving past the gate will first operate the locking mechanism to release the gate and then move the gate to the open position.
My invention provides further, novel means for raising a swinging gate to prevent its sagging.
Other novel features of my invention are hereinafter fully described and claimed.
In the accompanying drawings which illustrate the preferred form of my invention-Figure 1 is an elevation view showing the gate in the open position, the post with which the gate latch lockingly engages being broken away. In this view the right hand crank shaft is represented in dotted lines in the position to which it is depressed by a wagon wheel. Fig. 2 is a plan view of what is shown in Fig. 1. Fig. 3 is an elevation, showing the gate closed. Fig. 4 is an enlarged fragmentary elevation of a portion of the gate shown in the closed position. Fig. 5 is an enlarged detail view, partly in plan and partly in horizontal section, the section being taken on the dotted line a-Z of Fig. 3. Fig. 6 is an enlarged, detail view, partly in plan and partly in horizontal section, the section being taken on the dotted line 0(l of Fig. 3. Fig. 7 is a cross section taken on the dotted line e-f of Fig.6.

spectively of two right angled pivot pins 4, the horizontal arms of which are secured in the post 2.
5 denotes a vertical post, having secured to it a catch 6 which is adapted to be auto matically engaged by a self closing latch 7 which is pivoted by a horizontal bolt 8 to the gate 1.
For swinging the latch 7 to release it from the catch 6, which is shown in Fig. 3, and also in Fig. 2, and to automatically swing the gate to and from the closed position, the following described mechanism is provided :Pivotally mounted respectively in two vertical posts 9 and 10, which are disposed to the right and left of the gate 1, as shown in Figs. 1, 2 and 3, are two crank shafts 11 and 12, which are respectively provided with crank arms 13 and 14. The crank arms 13 and 14 are disposed adjacent to the road, denoted by 15, and are adapted to be consecutively engaged and swung by a vehicle wheel or runner, not shown, which is traveling in either direction along the road past the gate 1. Secured one above the other on the gate 1 are two plates 16 and 17 between which is mounted a horizontal lever 18 pivoted by a vertical bolt 19 to said plates. A cord 20 is secured at its lower end to lever 18 and passes between the plate 16 and the gate 1, thence upwardly to the latch 7 to which it is secured to the right of the bolt 8, as viewed in Fig. 4. The lever 18 extends from the gate 1 past the post 2, and has pivoted to it one end of a substantially horizontal rad 21 the other end of which is screw threaded and has mounted on it two nuts 22 and 22. Encircling the rod 21 between the nuts. 22 and 22 and having one set of ends bearing respectively against said nuts are two coil springs 23 and 24 the other set of ends of which bear against the vertical arm of a right angled crank pin 25, the horizontal arm of which is pivoted in a crank arm 27 on the rock shaft 11 and parallel with the crank arm 13. The vertical arm of the crank pin 25 is provided, as shown in Fig. 7 with a horizontal hole 25 in which is loosely and slidably mounted the rod 21. Pivoted at one end to the lever 18, and extending from the lever in a direction opposite to the rod 21, is a substantially horizontal rod 28, the other end of which is screw threaded and has mounted on it two nuts 29 and 29. Encircling the rod 28 between the nuts 29 and 29 are two coil springs 30 and 31 having one set of ends bearing respectively against the nuts 29 and 29, and having their other ends bearing against the vertical arm of a right angled. crank pin 26 slidably mounted. on the rod 28 and corresponding in construction to the crank pin 25 already described and illus trated in Fig. 7 The horizontal arm of the crank pin 26 is pivoted to the crank arm 32 of a rock shaft 33 horizontally pivotally mounted in a block 34 secured to the post 10. Two spur gear wheels 35 and 36 which mesh with each other are respectively secured to the rock shafts 12 and 33.
For bracing the gate 1, I provide the construction best shown in Figs. 1, 2 and 4. Two parallel boards 37 are secured to opposite sides of the gate 1, and extend upwardly from the lower free end of the gate past and over the post 2. An upwardly and downwardly extending rod 38 is disposed between the boards 37 and has mounted on its screw threaded upper end a nut 39, which bears upon the upper side of a plate 40 secured to and mounted upon the upper ends of the boards 37. The lower end of the rod 38 is provided with an eye 41 in which is secured the upper end of a flexible device, such as a rope 42, which is secured at its lower end to the post 2. The boards 37 serve as a brace, and the rod 38 and rope 42 as a flexible stay, which bears downward on the brace for preventing the free end of the gate 1 from sagging. I By tying the rope 42 around the post 2, below the pivot pin 4, as shown, the stay may be circumferentially adjusted around the post to the proper position. By using a flexible device, such as a rope, the stay may be readily attached to the post without the employment of a separate securing device. When the gate is swung from the closed to the open position, the offset relation of the stay brace 38 to the gate pivots 4 will tend to tip upwardly the free end of the gate. This tendency will be slight and will be partly nullified by the stretching of the flexible member 42, and spring of the brace 37 The customary looseness of fit at the pivots 4 will permit of such tilting of the gate as is not nullified by the yielding of the stay 42 and brace 37.
In operating the invention, theparts being as shown in Fig. 3, a wagon wheel or vehicle runner moving toward the gate 1 from the right, will strike the crank arm 13, thereby swinging the rock shaft 11 and with it the crank arm 27, which will force the crank pin 25 against the spring 24, which, by bearing against the nut 22, will, through the intermediacy of the rod 21, first swing the lever 18 so as to draw the cord 20 so as to release the latch 7 from the catch 6. Continued swinging of the lever 18 will swing the gate 1 to the open position, shown in Figs. 1 and 2. A vertical post 37' may be employed to limit the opening movement of the gate. The parts will now be in the positions shown in Figs. 1 and 2. Continued forward movement ofthe vehicle wheel or runner will depress the crank arm 13 to the position shown in dotted lines in Fig. 1, in which position the wheel or runner will pass of the crank arm. l/Vhen the crank arm 13 is depressed to the position shown in dotted lines in Fig. 1, the coil spring 24 will be compressed by means of the crank arm 27 and the crank pin 25. After the runner or wheel has passed over the crank arm 13, the spring 24 will force the crank pin 25 toward the nut 22, thus again swinging the crank arm 13 to the position shown in solid lines in Fig. 1. At this time the crank arm 14 will be in the position shown in Fig. 1. After the vehicle wheel or runner has passed through the gateway it will strike the crank arm 14 and will swing it to the position shown in Fig. 3, thereby swinging the crank arm 32 to the position shown in Fig. 3 through the intermediacy of the rock shaft 12, gear wheels 35 and 36 and rock shaft 33. This movement of the crank arm 32 will cause the crank pin 26 to move the rod 28, through the intermediacy of the spring 31, and nut 29, thereby swinging the gate 1 to the closed position by means of the lever 18. The continued forward movement of the vehicle wheel or runner will further depress the crank arm 14, thereby compressing the spring 31, until the wheel or runner has passed or run over the crank arm 14. At this time the spring 31 will cause the crank arm 14 to be again swung to the position shown in Fig. 3. The parts will now all be in the initial position shown in Fig. 1.
If a vehicle wheel or runner is traveling to the right, as viewed in Fig. 3, it will first strike the crank arm 14, and will swing it to the position shown in Fig. 1, thereby, through the intermediacy of the rock shaft 12, gear wheels 35 and 36, crank arm 32, crank pin 26, spring 30, nut 29, and rod 28, swinging the lever 18 so as to release the latch 7 from the catch 6 by means of the cord 20. After the latch is released, the continued movement of the lever 18 will force the gate to the open position, shown in Fig. 1. At this time the crank arm 14 will be depressed to the ground and the vehicle wheel or runner will run over it. The spring 30, which has been compressed when the crank arm 14 was depressed to the ground, will now, through the crank arm 32, crank pin 26, rock shaft 32, gear wheels 35 and 36 and rock shaft 12, swing the crank arm 14 to the position shown in Fig. 1. The crank arm 13 will also be in the position shown in Fig. 1, so that continued forward movement of the vehicle runner or wheel will bring it against the crank arm 13, thereby swinging the said crank arm to the position shown in Fig.3. This movement of the crank arm 13 willcause the gate to be swung to the closed position, shown in Fig. 3, through the intermediacy of the rock shaft 11, crank arm 27, crank pin 25, spring 23, nut 22, rod 21, and lever 18. Continued movement of the vehicle wheel or runner in the same direction will depress the crank arm 13 to the ground, thereby compressing the spring 23 until the wheel or runner has run over the crank arm 18, at which time the spring 23 will, by the means already described, swing the crank arm back to the position shown in Fig. 8.
From the above description it will be seen that a vehicle moving in either direction will automatically open and close the gate 1.
I do not limit my invention to the structure shown and described as many modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is
1. The combination with a gate post, of a gate hinged to the post, a diagonal brace extending from the lower part of the free end of the gate to the upper part of the hinged end of the gate and having its upper end extending across the axis of the gate, and a stay secured to the post and to the upper end of the brace.
2. The combination with a gate post, of a gate hinged thereto, a diagonal brace extending from the lower part of the free end of the gate to the upper part of the hinged end of the gate and having its upper end extending across the axis of the gate, and a stay secured to said upper end of the brace and circumferentially adjustably secured to the post.
3. The combination with a gate post, of a gate hinged thereto, a diagonal brace extending from the lower part of the free end to the upper part of the hinged end of the gate and having its upper end extending across the axis of the gate, and a stay secured at its upper end to the upper end of the brace and having a flexible lower end secured to the gate post.
In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
