JOHN SCHADE, JR. OF BROOKLYN, NEW YORK.
SPRING FASTENING DEVICE.
Specification ofLetters Patent.
Patented Jan. 16, 1917.
Original application filed March 13, 1913, Serial No. 754,128. Divided and this application filed December 23, 1914. Serial No. 878,653.
To all whom it may concern Be it known that I, JOHN Sermon, Jr., a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Spring Fastening Devices, of which the following is a specification, ac- I companied by drawings.
This invention relates to spring fastening devices for electrical conductors.
The particular form of fastening device upon which the present invention is an im provement insevera'l respects, is thatforin in which the device is made out of spring wire. It is highly desirable that such a device made out of wire be provided with attaching means for securing the device directly to a support and acting to maintain the device upright and restrain it, when fastened down to the support, from tipping sidcwise under transverse strain. V
The device should also enable the conductor to be firmly gripped and clamped in defined position to permitthe ready insertion and removal of the conductor and in-- sure good electrical contact at all times be tween the conductor and the fastening device.
The present application is a division of my co-pending application Serial No. 75,128, filed March 13, 1913, said application being a renewal of my application Serial No. 347,757, filed December 13, 1906. The invention is illustrated in the nccompanying drawings, in which- Figures 1, 2, 3, 4 and 5 are perspective views of different forms of fastening devices embodying the invention.
My improved fastening device is preit'er ably ado from a single piece of resilient material, as for ins ance metallic spring wire,
and it may be lnade out of a single piece' of wire or several pieces, if desired. In each of the figures, the spring wire is 100 ed on itself to form body and spring me'm ers A and B and vas shown, each of said members is formed for substantially its-length, of parallel wires. Both the body and spring members A and B are provided with angular retaining portions C and C at points oppcr site each other, whereby a conductor maybe firml gripped when the body and spring" mom are A and B are forced into c'oiiperative relationship, and at least one of said lying. in Contact with the retaining portions over an extended surface on the conductor.
The wire of which the spring fastening device is formed may have any suitable shape in cross section and in Figs. 1, 3, 4: and 5, round wire is shown, while in Fig. 2 wire which is rectangular in cross section is shown. In Fig. 2 the area. of contact between the conductor K and the fastening device is increased and the same effect can be obtained by flattening'the round wire inside the bends of the retaining portions.
Although in Figs. land 5 the angular retaining portions C are formed of the ends of" the wire, this construction is equivalent to that shown in Figs. 1, 2 and 3, in'which the angular retaining portions 0 are formed by bendin the body member A.
In all 0 the forms of the invention shown in the figures, the spring members B are provided with thumb pieces E which extend outwardly away from the loops D of the device and provide-means for forcing the body and spring members into cofiperative relationship.
In the forms'of the invention sho n in the'drawings, I have preferred to illustrate the device as made out of a single piece of spring wire looped on itself at D toform oppdsin normally separated body m1 spring bers bein composed forsulistantiall their length 0 'parallel wircs. Both bo y and spring members1A and B are provided with angular wire retaining portioiis C and C at points op osite :to .each other, the respective embersAnnd B, each of said memwires of t e retaining portions lying closely adjacent ci cirhthegside by side, so that the between alliof-thewi-res of the retaining portions C and Q, when the body and spring members areforced into coiiperative relationship. At least one of the angular retaining portions 0 or C of the body and spring inenilwrs, is shaped to form a right angle or less. and ear-h separate wire of the angular relaining portion which is equal to a right angle or less, has a pair of opposing points of contact with the eoinluetor K at tangents to the (OlHlllCl-UX'. It will be seen that such pairs of tangential contacts on separate wires lie in a plane nearer to the center oi. the roinlurtor K than said plane is to the apex of the said angular retaining portion. This eoi'istrurtion causes the eondoctor to become firmly wedged within the angle of the retaining portion so that it. is gripped and held in defined position between the 0 '1 'MiSln mints ot' contaeton the a 1 separate. wires of the said retaining portion. It is for this raason that one at least. and preferably both of the angular retaining portions (l and (f' are shaped to form a right angle or less. In the forms of the invention illustrated, both, or at least one of the ends H of the lengths of wire forming the deviees, are bent to form a broadened foot adapted to lie tiat upon a base or support I andeapable'ot receiving a securing 'lerice J for securing the spring Fastening .e directly to the support I. The brow d foot formed by the portions II also arts to maintain the clip upright and restrain it. when fastened down to the support, from tipping sidewise under transverse strain.
The other terminal of the eirruit L may be secured to the securing device. J as by means of the nut O.
In Fig". 1 the angular resistant or retain 'ing portions 0 of the body member are in closed by the angular retaining portion C of the spring member and this same construction is true of Fig. 2.
In Fig. 3 the angular resistant or retaining portions C of the body member inclose the angular resistant or retaining portion G of the spring member.
In Fig. 4 the projecting hooked ends forming the resistant or retaining portion C of the bodymember A, are inclosed by the angular retaining portion C of'the spring member B, and in F 5 the construction is similar to that shown in Fig. 4, except that the. portions H of the free ends of the wires are brought together, instead ol. being separated, as in Fig. 4.
l rlaini and desire to obtain by Letters Patent the following:
A spring fastening device for eleetrieal conductors, made of spring wire looped on itself to form opposing body and spring ineinlwrs, eaeh eoniposed for substantially. their leugth'of parallel wires, and both having angular wire retaining portions at opposite points, the respective wires of said retaining portions lying elosely adjacent earh other, side by side, whereby the conductor may be inserted transversely between all of thewires of said retaining por ions.
when said body and spring members. re forced into cooperative relationship, at at one of said angular retaining portions ,5 ing shaped to form a right angle or .4, having opposing points of contact with eoialaetor at tangents to the conductor ly in p'lane nearer to the center of the duetor than to the apex of the said angular retaining portion, thereby causing tin sonduetor to become firmly wedged within the angle of said retaining portion and gripped and held in defined position between the opposing points of contact on the separate. wires of said retaining portion, one of said body or spring members extending beyond the ang'ulz wire retaining portion of said member and in a direction away from The loop of the fastening device, said'extension having a broadened foot adapted to lie fiat upon av base or support, and acting to maintain the device upright and restrain it, when fastened, from tipping sidewise under transrerse strain, whereby the fastening device may be secured (ii) a base or support.
In testimony whereof I have signed this in specification in the presence of two subscrib-
