UNKTE which one end of the post 2 is ANTHONY J. CITRISTOPHER, 0E BALDWTNSVILLE, NEW YQfEtK.
To all whom it may concern:
Be it known that I, ANTHONY 5. CHRIS- rornnn, a citizen of the, United States, re-.
WVire-Fastening Devices, of which thefollowing is a specification.
This invention relates to wire fastening devices the object in view being to produce a simple, reliable and practical device for fastening or securing in place wires and preferably insulated wires such as are used in alarm circuits and for other electrical connections, the device embodying construction bymeans of which plurality of wires may lie quickly fastened iir fixed relation to a wall, post or other support and quickly detached or unfastened when required. With-the above and other objects in view the invention consists in the novel construction, combinationand arrangement herein fully described, illustrated and claimed.
In the accompanying drawings Figure 1 is an elevation of the fastening device showing the'clamping position of the same in relation to a plurality of wires.
' Fig. 2 is a similar view showing the unclamping relation of the parts of the has tening device. I
Fig. 3 is a plan view of the base member of the device.
Fig. 4 is a detail viewof the movable clamping jaw of the device.
Fig. 5 is a? detail view of the post'.
Fig. 6 is a fragmentary section showing the relation between the post and the thumb piece or key;
Fig. 7 ;'is a view of a modified form of base. 7 v
The Wire fastening or clamping device consists of a base 1, a post 2', a movable clamping jaw 3, athumb piece or key t, and a jaw openin spring 5.
The base 1 is ormed with holes 6\to receive suitable fastening devices such as nails or screws by means of which the de' vice as a whole may be secured to a wall or partition or other light support. The base 1 is also formed with a square hole 7 in.

Application filed January 15, 1919. Serial Iilo. 271,23
The post 2 is preferably square in cross section and is formed with. a groove 8 around the outer end thereof to receive the thumb piece or key 4:. The key 4': is formed with a socket 9 to receive the. outer end of the post 2 in such mannerthat the key or thumb piece '4 has a swiveled connection with said post adapting 'hureb post to be turned for a purpose which will appear The clamp 3 is :Eori'ned with a. square cen tral hole 10 to receive the post 2 and enable the clamping member Ste slide upon. said post. At opposite sides of the hole it), tl'e clamping member 3 is formed with curved and substantially semi-circular portions ll. which partially embrace the wires sliown 19. and clamp the same firmly against the base 1.
The spring 5 which is oi: the compression type surrounds the post 2 between l and the clamping jar-v and move the clamping aw away from said base when the key or thumb l; s turner the proper direction.
The clan'iping position of the tl astening device is illustrated in Fig. 1 wherein it will be seen that the wires 12 are held between the movable clampingjaw 3 and the fined base 1, the wing portions or" the thumb piece t bearing against the clan'iping jaw 3 at opposite sides of the center thereof. By givingthe thumb piece 4 a quarter turn, in other words by turning said key from the position shown in Fig. 1 to. the position shown in Fig. 2. the clamping member or jaw 3 is allowed to move away from the base 1, being actu' 'ated by the expansion of the s ring 5; This enables the wires 1% to be easi y and quickly removed from the clamping device. By reversing the operation ,just described, the wires may be again clamped in fixed relation to the device.
As shown in 7, thepbase l is provided with the curved recesses 1" for 're-' ceiving the wires. r
A wire clamping device comprising a fixed base, a post extendingfrom said base and non-circular shape in cross section, a
clamping jaw slidable on said post and havingan opening through which-said pest expression spring surrounding said post and interposed Within said baseand clamping member, and a thumb piece having a swivel connection with said'post and adapted by a quarter turn to press said clamping member toward the base or re]ease the same, said clamping member comprising cnrved portions at opposite sides of the center thereof which curved portions are adapted to partially embrace and hold a plurality of wires. 10
In testimony whereof I afiix my signature.
