LOCKING-CLAMP FOR GATES AND THE LIKE.

Specification of Letters Patent.

Patented J an. 11, 1916.

Application filed January 23, 1915. Serial No. 3,877.

To all whom it may concern Be it known that I, ISRAEL L. LANDIS, a

citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new in Looking Clamps for Gates and the like, of which the following is a specification.

This invention relates to certain improvements in a locking-clamp, which is particularly intended for use on farm gates of that type in which the gate can be adjusted vertically bodily, so as to permit the passage of small animals thereunder, while barring larger ones, or if desired, angularly with re spect to the ground,"or so as to accommodate the gate to hill-side's or inclined ground; and while I have so shown it in the accompanying drawing, and will hereinafter describe it in connection with such a gate, yet I desire it understood that I. do not limit its application to gates only, as it is applicable for use in connection with other structures, and can be employed for clamping two or more pieces together in many devicesu The main object of the invention is to provide a very simple,'inexpensive and efiicient looking-clamp of the above mentioned general character, which can be readily applied to the parts to be clamped or held in their adjusted positions, and easily manipulated, to permit of the desired adjustment of said parts, and it consists in various details of construction and combination of parts, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawing, which serves to illustrate the invention as applied to a gate Figure 1, is a side view of a gate, showing its parts by continuous lines in their normal positions, and by dotted lines the positions to which they can be vertically adjusted and held by means of one of the looking clamps, another of said locking clamps being shown at the hinged end of the gate for its bodily adjustment; Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1, looking in the direction indicated by the arrows Fig. 3 is a detached perspective view of the lockinglever employed in the clamp at the lower front portion of the gate; Fig. 4c is a vertical sectional view taken on line 41 of Fig. 1, looking in the direction indicated by the arrows; Fig. 5 is a detached perspective view of the lever employed in the clamp used for the bodily adjustment of the gate, and Fig. 6 is a fragmental face view of a modified construction of the gate, and also illustrating a modification in the construction of the locking clamp for its hinged portion.

Corresponding numerals of reference refer to like parts throughout the different views of the drawing.

Referring now to Fig. 1,-the reference numerals 10 and 11 designate the usual fixed gate posts, 13 a swinging sub-post, which is hinged to the post 11 at suitable points thereon. The numerals 1 1 and 15 designate the end battens of the gate proper, 16 the intermediate battens, and 17 the horizontal slats or bars, which are pivoted to the battens.

13y reference to Figs. 1, 2 and 4 of the drawing, it will be understood and seen that the battens are arranged in pairs embracing both sides of the horizontal slats or bars- The battens 1 1 are slidable vertically against the adjacent face of the sub-post 13,

and are provided at their upper portions with oppositely mounted plates 18, which are identical on both sides of the battens and are bolted through the latter. The rear portions of the plates 18 are bent over the rear corners of the post 13 as at 19 (see Figs. 1 and 6), but said bent portions are separated sufficiently .to permit of the passage therebetween of the upper hinge 20, which connects the subpost 13 to the rear gate post 11, near its upper end. Below the pair of plates 18 the battens 14 are provided on opposite surfaces thereof with horizontally and rearwardly extending plates 21 and 22, which are secured to the battens 14:

.by means of bolts 23, which have heads at one of their ends and nuts 24 at their other ends. The plate 22- is provided with a downward extension 25, which is slightly spaced from the batten 14, adjacent thereto, and is provided in its lower portion with an opening through which is extended a screw bolt 26, which is extended through both of the battens and one of the slats 17, and has on one of its ends a head and on its other end a nut 27. Fulcrumed on the bolt 26, between the extension and the batten 14 adjacent thereto is a looking lever 28, which is of substantially the shape and construction shown in Fig. 5 of the drawing; that is, it has a flat portion 29, tapered toward its free end. The rear ends of the plates 21 and 22 project rearwardly of the sub-post 13, and are connected by means of a bolt 30, which has on one of its ends a nut 31, to be usedfor tightening or clamping said plates with respect to the sub or swinging post 13, should the side of the latter become worn by reason of the action of the flat portion 29 of the locking lever 28, which flat portion. is adapted to be inserted between the plate 22 and the adjacent surface of the sub-post so as to hold the gate at the desired point on the sub-post after being vertically and bodily adjusted thereon.

The frame of the gate is held rigidly in its rectangular form, shown by continuous lines in Fig. 1 of the drawing, and in different angular or oblique forms, one of which is shown in said figure by dotted lines, by means of a pair of diagonal bracebars 32 and 33, which are pivotally connected at'their upper ends to the upper ends of the battens 1%, at the hinged end of the gate. At its lower extremity each of said brace-bars is slidable longitudinally between the faces of the front pair of battens 16 and the clamping device used for sustaining the gate in its normal or angularly adjusted positions. This clamping device, shown in Figs. 1 and 2 of the drawing, consists of a pair of headed bolts 3 and 35, extended transversely through the front pair of battens 16, at their lower portions. The head ed portions of the bolts 3% and are connected by a plate 36, which is spaced from the battens 16 on one side of the gate at a sufficient distance to permit of the brace bar 33 being located between said plate and battens. The bolts 3% and 35 are sc"ew threaded near their ends opposite the heads of said bolts, and each has mounted on its screw threaded portion a nut 37, which bear against a flat plate 38, which also connects the bolts 3 1 and 35, but near their screw threaded ends. Connecting the bolts 34 and 35 inwardly of the plate 38 is another flat plate 39, which rests against the bracebar 32, which is located on the opposite side of the batten 16 from that on which the first mentioned brace-bar is located. The plates 38 and 39 are loosely mounted on the bolts 34: and 35, but are spaced apart so as to receive therebetween a locking lever, which is indicated as a whole by the reference numeral l0, which lever is fulcruined on one of the bolts, preferably the upper one 34:, of the clamping device now under consideration.

The lever 40 is of substantially the construction and shape shown in Fig. 3 of the drawing; that is, it is beveled or wedge-shaped toward one of its edges and has on its outer face a pin 41 to strike against the plate 38, so as to restrict the downward movement of said lever or the upward or opposite movement thereof, for it is obvious that by reference to Fig. 1, when the lever is turned on its fulcrum so as to remove its beveled portion from between the plates 38 and 39, the pin 41 will strike against the upper beveled portion 42 of the outer plate and thus prevent said lever turning farther on its fulcrum. By this arrangement, it is obvious that by turning the lever 10 downwardly between the. plates 38 and 39, the latter plate will be forced against the brace-bar 32;

and at the same time the plate 36, which unites the bolts 34 and 35 on the opposite side of the gate, will be drawn against the brace-bar 33, thus causing said bar as well as the bar 32, to be pressed against'the battens 16, and thus holding the parts of the gate in their normal or adjusted positions. In order to change the positions of said parts, the lever 40 may be turned upwardly 011 its fulcrum, in which operation the clamping members will be loosened so that the parts of the gate may be shifted or adjusted to the desired positions, where they can be again fastened by turning the lever 10 downwardly.

In Figs. 1 and 6, a locking clamp for the bodily adjustment of the gate is employed and has been above described, and in each instance the construction of the members of said clamp is the same, but it will be noted in Fig. 6, that the position of the lever 28 and the extension 25 on the clamping member 22 is reversed. With this exception the constructions in said clamps are identical.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In a locking clamp, the combinati with a support including the parts to be clamped, of a pair of bolts extended through the support and. having a detachable connection near one of their ends, a pair of plates loosely mounted on said bolts near their other ends, said plates having their adjacent surfaces plain or fiat and a suitably fulcrumed wedge-shaped lever positioned to be interposed between the pair of plates and having on one of its surfaces a projection adapted to strike one of said plates and restrict the movement of said lever.
