HINGED GUY-CLAMP.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed November 15, 1915. Serial No. 61,711.

To all whom t may cof/cern Be it known that l.. Jasmin BLACKBURN, a citizen of the United States, and resident of Webster Groves, Missouri, have invented certain new and useful improvements in Hinged Guy-Clamps, of which the following is a specification Containing' a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof,

My invention relates to improvements in hinged guy clamps wherein a plate, arranged to be secured to a pole is provided with bearings in which, to pivotally or hingedly support a. guy clamping means comprising a tapering socket and wedge.

The object of my invention is to construct a simple inexpensive and easily operated guy clamp which may automatically adapt itself to different arrangements of guys; and to arrange a guy clamp comprising a tapering sock-et and wedge, wherein an eiiicient, and easily operated means is employed for holding the wedge in different positions relative to the socket.

With the above object in view, my invention consists in certain novel details of construction and arrangement of parts as hereinafter fully described, pointed out in my claims and illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of a device embodying my invention, a fragment only of a pole being shown;

Fig. 2 is a frontor face view of the device;

Fig. 8 is a longitudinal sectional elevation of the device taken through the approximate center thereof;

Fig. 4C is a transverse sectional plan of the device taken through the approximate center thereof;

Fig. 5 is an end view of the socket alone;

Fig. 6 is a vertical sectional elevation of the socket;

Fig. 7 is an end view of the wedge alone;

Fig. 8 is a side elevation of the wedge;

Fig. 9 is a plan of the wedge;

Fig, 10 is a vertical sectional elevation of the socket and wedge with a section of guy therein showing the Wedge held against inward movement relative to the socket, to permit movement of the guy over the wedge;

Fig. 11 is a sectional plan of the socket and wedge showing a tap screw in position to hold the wedge against movement inwardly relative to the socket, and

Fig. 12 is an elevation on a reduced scale showing the whole structure of my invention employed as a guy clamp, and the plate of my invention as used for supportinga guy to prevent splitting of a wooden pole.

Referring by numerals to the accompanying drawings, 15 designates a plate of substantially rectangular formation, and whose cross section is arcuate to conform to a pole, and which plate has on its rearmost face spurs 16 to assist in the holding of the plate in position on a pole and through which plate there is formed openings 17 for the further or permanent securing of the plate to the poles by use of lag screws, spikes, or the like,

Formed through the center portion of this plate there is an aperture 18 through which a guy is to be passed. Outstanding from the plate and on each side of the aperture 18 there is formed a bearing 19 and outstanding from the plate above the aperture 18 is a channeled guy supporting lup' 20.

The numeral 21 designates a socket which tapers from end to end, is formed hollow throughout and in cross section is substantially oblong` with parallel sides and rounded ends. On each side of the socket and eX- tended beyond. the body thereof is an integral trunnion 22 which is arranged to seat in the bearing 19 of the plate to permit of a pivotal or hinged movement of the socket relative to the plate.

In the one side wall of the socket there is a way 23 which opens to the interior of the socket and parallels the median line thereof. In this way 23 adjacent the larger end of the socket there are the shoulders 24.

In the opposite wall of the socket arranged along the median line thereof is one ormore tapped openings 25 arranged to receive a set screw 26 for the purpose of holding the wedge block 27 with its feather 28 seated in the way 23 and with its shoulders 29 against the shoulders 24 of said way whereby to hold the wedge outwardly relative to the socket 21 as clearly shown in Figs. 10 and 11, to permit easy movement of the guy around said wedge and through said socket. In the wall of the socket, having the way 23, there is a tapped opening 30 intersecting said way for the purpose of receiving the tap screw 26 whereby the tap screw may be employed te move the wedge to free its feather from said way and permit the wedge to be drawn by the guy into said socket to clamping position.

The device of my invention is designed primarily for use in connection with guys extended! through openings formed in Wooden poles and .in view of the fact that different arrangements of guys necessitate the forming of said openings through the poles at different angles such for instance as horizontally through the poles as show-n in Fig. 3,. or diagonally through a pole as shown in Fig. l2.

have found it advantageous to hingedly or pivotally support the guy clamping means so that the clamping means may be held in substantial alinement with the guy, which arrangement obviates angles or bights in the guy offering resistance to the movement of the guy through the clamping means in adjusting the guy as well as obviating anvgleS tending to break the wire or at least mar its protecting surface such as galvanizing. r

Having thus described my invention what I claim as new therein and desire to secure by Letters-Patent of the United States therefor is 1. ln a device of the class described, a tapering socket having openings through opposite walls thereofa an axial way formed in one of said walls, and an offset shoulder Y in said way, a wedge having'less thickness than the distance between said opposed walls Gopies ofvthis patent may be obtained for ve cents cach, by addressing the Commissioner of Patents,`

of the socket andra feather having an offset shoulder arranged to coperate with said way and shoulder for holding the wedge against movement relative to the socket.

2. In a device of the classdescribed.y a tapering socket having tapped openings in its opposite walls, a way inone of said walls intersecting said tappedV opening and a shoulderin said way, a wedge for inser-` tion in said socket, a shouldered feather on said wedge, and a screw arranged to be inserted in one or the other of said tapped openings to engage the wedge to either'hold its feather and shoulder seated in the way Y,

socket, substantially as shown and for thev purposes stated.

ln testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

JASPER BLACKBURN.
