Renewed January 21, 1933 4 Claims. (01. 292-87) My invention relates to a stop for pivotally mounted doors or gates, and the objects of m invention are:

First, to provide a door or gate stop which is 5 very simple and inexpensive of construction, positive and dependable in action, and which will not readily deteriorate or get out of order;

Second, to provide such a stop well adapted for installation in locations out of doors and exposed to the weather, due to the absence of joints and of any open portions capable of retaining rain,.water or dbris of any description which might tend to hinder normal functioning;

. Third, to provide a .stop for a hinged door or gate which will afford the greatest safety and convenience to a motorist having to drive a car through the doorwayor gateway at which-said door or gate is installed, said stop being so designed as to be forced aside automatically when said'door or gate is swung fromitsclosed posi-- tion outwardly over it, and to catch said door or gate when any force, such as the wind or gravity, causes it to swing back over said stop toward its closed position, said door or gate being readily released from said stop when caught, by applying downward foot-pressure on the head of the same; 1

Fourth, to provide such a door or gate stop which, due to its flexibility, will not be likely .30 to trip or in any way injureany'person striking it while moving upon the ground, floor or pavement in which the stop is installed; and

Fifth, to provide a novelly constructed door or gate stop.

. 5 With these and other objects in view,- as will appear hereinafter, my invention consists of oer.- tain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly 140' set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which: I

Figure 1 is a side elevational view of my door or gate stop installed in the ground and clear of the door or gate to which it forms astop; Fig. 2 is a top View of the same; Fig. 3 is a side elevational view of the'same, bent over by-the door or gate as it passes over said stop outwardly from its closed position and in the direction in which the head of said stop is pointing, with said door or gate shown in cross-section, fragmentarily; Fig. 42 is a side elevational .view of said stop, similarly installed, bent over by the door or gate as it passes over the same inwardly toward its closed position and in the direction in which the head of said stop is pointing, said stop having stopped said door or gate, which is shown in crosssection, iragmentarily; Fig. 5 is a side elevational view of said stop, similarly installed, and in the position it has assumed immediately after the door or gate has been released from the same by downward pressure on the head of said stop by the foot of the person releasing the same, said foot being shown fragmentarily, and saiddoor or gate being shown in cross-section, fragmentarily; Fig. 6 is a vertical cross-sectional view of the base of my door or gate stop, with a portion of the spring shown also, fragmentarily; Fig. 7 is a vertical;cross-sectional view of' a modified form of said base, with a portion of the spring shown also, fragmentarily; Fig. 8 is a perspective view of a modified form of my door or gate stop, installed in the ground, andclear of the door or gate to whichitformsa stqp, and Fig. 9 is aside elevational view on ,a reduced scale of another modified form of the base of my stop, with the spring shown fragmentarily,

- Similar characters of reference refer to similar parts and portions throughout the several views' of the drawing. 7

r In the one form of my door or gate stop shown in Figs. 1- to 6, inclusive, the base 1, is a section of galvanizedmetalpipe, sufliciently long to anchor the door or gate stop rigidly when properly installed-by being embedded vertically in the ground or in a hard floor or pavement. Screw threads. are provided on the exterior of a portion of, said base adjacent to its lower end, over which the galvanized metal basexcap 2, with threaded interior, is screwed, closing said end. Screwthreads areprovidediin the interior of thebase for a short'distance from its upper end, and the plug 3, which is a threaded, metal disc, slotted at its top, is screwed into said base, leaving the'socket 4 in the upper portion of the same. The depth of said socket is slightly greater than its diameter. I

' The spring 5, is a hollow, cylindrical coil or heavy, resilient metal wire, its lower portion being in the socket 4 in the base, in which it fits snugly, with its lower end engaging the top of the plug 3. With the spring in place in the socket, asabove' indicated, molten solder is poured in said socket, filling the same to the top and attaching 'the spring strongly and'rigidlyto the base .in true alinement with the same.

The head 6, is a wedge-shaped piece of cast metal integral with the cylindrical lug 7, which joins said head at the end of the same farthest from the thin edge of said wedge, and close to one of the two inclined sides of the same which terminate in said thin edge. The full length of said lug 7, which is three or four times its diameter, is enveloped by the upper portion of the spring 5, which is welded to said lug, making a strong, rigid connection and supporting the head with the thinedge of the aforesaid wedge at its top. The perimeter of the outside-of the spring 5 is flush with the inclined side of the aforesaid wedge nearest to the lug '7, and is offset about one-half of the length of said lug from a the other inclined side of said wedge. The lower end of the head, being the side farthest from the thin edge of the aforesaid wedge, between said spring and said inclined. side, forms the catch 8, which is inclined at an angle downwardly from its intersection with the spring. A l

of the edges and corners of the head are slightly rounded off to prevent damage to anything striking it.

The door' or gate 9, to be stopped by my door or gate stop, has a short section of its bottom portion near the edge of said door or gate farthest from the pivotally mounted end thereof, and slightly longer than the width of the head 6 of the stop, prepared by either cutting away the two lower edges a small amount to rounded cross-sections or nailing onto said short section against the bottom of said door or gate the bottom cleat 10, with sides flush' with the sides of the door and with its lower edges slightly rounded. The side cleat ll, of the same length as the bottom cleat 1'0, and of a wedge sh'aped cross-section, is nailed to the: aforesaid short section of the door or gate on the side thereof which faces inwardly when said door or gate is closed; The thin edge of said wedge-shapedcleat is at the top; and the lower edge of thesarne-is flush with one of the aforesaid rounded edges ofthe door or gate 9, or of the bottom cleat 10', and is rounded off continuously with the same. The width of said side cleat ll between said thin edge and lower edge is slightly greater than the length of the catch 8. r

Over said section of the door or gate 9], prepared as' above set forth, the shield 12, which is a thin, flat, rectangular piece of strap metal, is

, screwed with countersunk screws, and conforms closely to the contour of the door" and-of the cleat or cleats thereon, extending higher on both sides of said door or gate than the top of the head-,6, of the stop, and completely protecting said door or gate from being marred by said stop when it strikes the same. of the rounded lower edges to which the'shield 12 conforms is topreveiit said edges from catching in the spring whilethe stop is'bei'ng bent overas the door or gate passes over it in either direction. The purpose of the wedge-shaped side cleat 11, is to bring the surface of the shield 12 into conformity with the inclined surface of the catch 8, which forms a more or less pronounced hook, interlocking with's'aid surface of the shield when said latch and said shield have been brought into engagement by movement of the door or gate 9 toward its closed position, as will be described hereinafter. Said interlocking, as an auxiliary to the stabilizing The purpose the shield 12, attached to the same, will strike the stop after said door or gate has reached the point. where an ample clear passage-way is permitted any vehicle which may pass through the doorway or gateway at which said door or gate is installed. Said stop is installed with the catch 8 pointing in the direction in which the shield 12 is moving as said door or gate, in swinging outwardly from its closed position, strikes the stop.

The top of the base 1' is set asnear the. elevation of the bottom of the shield 12" as it may be and allow the door or gate, protected by said shield, to bend the spring and pass over the same and the head, as said door or gate swings over the stop outwardly from its closed position. The surface of the ground or of the floor or pavement in which the base is installed: should be flush with, or a short distance below the top of said base. I

When the aforesaid door or gate is closed and is to be opened to permit a vehicle to pass, the person opening the same is not obliged to push it until it has cleared my stop, but he may push it outwardly smartly while standingv at some dis tance from said stop. When this is done, the momentum of the door or gate carries it. past said stop, bending thesame over with the catch 8 pointing downwardly as it passesover said stop. When cleared by the door or gate, the spring and the head snap back from said bent over position to their normal, erect position. If,-after said door or gate has passed over and cleared the stop outwardly, any force, such as wind or gravity, causes said door or gate to swing inwardly with sufiicient momentum to bend the stop over in the direction opposite to that in which it is bent whenfsaiddoor or gate swings over it outwardly, as hereinbefo're described, the head 6 and the ing '7 assume a horizontal position, with the catch 8 pointing upwardly, and said catch, when struck by the shield 12, stops the said inward motion of the door or gate, said lug '7 within a portion of the spring 5 which engages the lowest portion of the shield-12, being longer than the surface of said catch, and thus preventing the impact of said shield against said catch from overturning the head. As hereinbefore set forth, the interlocking, inclined surfaces of thecatch and of the portion of the shield in'engagement therewith, co-operate with'the said stabilization brought about by the lug 7 to ensure stoppage of the door or gate in a positiveand dependable manner.

When the door or 'gat'e'has swung outwardly from its closed position over the stop, and one desires to close said door or gate again, he first swings the same inwardly with one of his hands until it hasassuined the position above described, with the stop bent over and the catch 8 engaging the shield 12; he then places/a portion of the sole of his shoe 13, upon the upper surface of the head 6 of the stop, and pushes the same downwardly, still pressingthe door or gate inwardly with his hand, so that said catch and said shield remain in engagement. When the upper end of the catch has been depressed nearly to the bottom of the rounded portion of the shield 12, hereinbefore described, the ,said foot is removed from the head 6, and the aforesaid pressure on the door, still continuing, moves the same inwardly and forces said head downwardly until the upper end of the catch engages the fiat bottom portion of the shield 12. The door or gate is then free to be swung further to its closed'position, the spring and thehead snapping back from their bent over position to their normal, erect position when cleared. r i

A slightlyrmodified' form of the base of my door or gate'stop, which is shown in Fig. 7 of the accompanying drawing, is suitable for mounting said stop on the surface of a wooden floor.

before described. Near the outer edge of said conical casting 14, three or more evenly spaced holes are bored for the countersunk screws 16, which are screwed into the wooden floor 17, to attach said casting securely thereto.

A slightly modified form of the upper portion of my door or gate stop, which is shown in Figure 8 of the accompanying drawing, is mounted in the socket of either a tubular or conical base 1,

. identical in all respects with one or other of the forms of the base hereinbefore described. As a substitute for the coil spring and cast metal head and 111g of the form hereinbefore described, the

fiat, metal spring 18, of such width as to fit snugly in the aforesaid socket, is employed. Said spring is placed in said socket in true alinement with said base, a short section of the lower portion of said spring having been bent over to form a small hook to anchor said spring securely in the socket which is then filled with molten solder.

At a suitable distance above the top of said base, the spring 18 is bent to form the hollow,

wedge-shaped head 19, with a perimeter similar to that of the head 6 of the form of my door or gate stop hereinbefore first described. The terminal portion 20, of said spring, immediately below the catch 21 (which corresponds to the catch 8 of said form first described) lies flat against a. portion of the upright, lower section of said spring, and is welded to the same, making said portion rigid, sothat it may perform the function of stabilizing the head of the stop exactly as performed by the lug 7 of said form first described, which said function has been hereinbefore set forth. The lower end of said terminal portion 20 of the spring is beveled off smoothly so that it will not catch on the shield 12, at-

tached to the door or gate 9. Said shield is at' tached to said door or gate in the manner hereinbefore described, excepting that no bottom cleat is required, and the lower edges of the section of said door or gate to which said shield is attached may be left square, since there is nothing on which the square edges might catch in a manner that would prevent the device from functioning.

Saidmodified formfconsists of thernetalcasting 14, in the shape of a low, wide, truncated The fiat spring form of my door or, gate stop above described is installed and functions in a manner similar to the coil spring form of the same first set forth hereinbefore.

A nodified form of the base of my door orgate stop,which is shown in Fig. 9 of the accompanying drawing, is identical with the tubular form of base hereinbefore set forth and illustrated in Fig. 6 of the accompanying drawing, excepting that it has two 90 degree bends, the upper of said bends-being located just below the plug 3, which partitions the socket 4 from the lower portion of the base, and the lower of said bends being located a few inches short of the cap 2, at the lower end of said base. In said socket an end of the spring 5 is embedded in solder, and said spring has attached to its opposite end the head 6 and lug '7 exactly as' in the form of the device hereinbefore first'set forth.- The purpose of said bends is to provide for mounting the stop in a horizontal instead'of a vertical position.

Figures 1, 3, f1; and'5 of ,the accompanying drawing illustrate the device and its operation when installed horizontally in said base, if they be considered as top elevational'views with the base shown fragmentarily and with the door or gate and its appurtenances shown in cross section, fragmentarily.

Said base is to be embedded in the'ground or in a hard floor or pavement, and positioned similarly to the device as first set forth with relation to the doorway or gateway at which the door or gate stop is installed to which it forms a stop, and with the spring in a horizontal position and pointing toward the axis of the pivotal supports of the same.

A portion of the end of said door or gate near its bottom and farthest from its pivotally supported end is prepared with the'cleats 10 and 11 the door or gate is moving in passing the stop from its closed to its opened position.

The purpose of the horizontally bent lower terminal portion of the base is to prevent rotation of said base when same is installed by embedding, as hereinbefore set forth.

The operation and functioning of the device when horizontally installed is similar in all respects to the operation and functioning of the device when vertically installed, excepting that in releasing the catch from the door or gate in closing the same, horizontal instead of vertical pressure is brought against the side of the head adjacent to the catch.
