CORPORATION OF NEW YORK CLAMPING DEVICE Application filed January 28, 1927.

This invention relates to clamping devices, and more particularly to a device for securing strands or cables to supports therefor.

The principal object of the invention is to provide a simple and inexpensive device for readily and securely attaching strands or cables to supports.

In accordance with the general features of the invention, there is provided in one embodiment thereof a member having a pair of oppositely disposed jaws adapted to resiliently engage the flanges of an I-beam and maintain an intermediate channel portion spaced from the face of the I-beam. The strands or cables are clamped to the face of the chan nel portion by means of resilient members having hooked ends engaging the flanges of the channel. The resilient members are also provided with loop portions to which similar members embracing additional strands or cables may be attached.

Other features and advantages of the invention will become apparent in the following detailed description, reference being had to the accompanying drawings, wherein Figs. 1 and 2 are fragmentary elevational views illustrating a cable clamping device embodying the features of the present invention; f

Fig. 3 is a cross sectional view taken on line 3*3 of Fig. 1, and

Fig. 4- is a perspective view of the improved cable clamping device.

. Referring now to the drawings in detail, the

numeral 10 designatesa portion of an I-beam having the usual flanges 11 and 12 and a web portion 13. A member indicated generally by the reference numeral 15 is adapted to be attached to the flanges of the I-beam, as best shown in Fig. 3. The member l5 is preferably composed of resilient'sheet metal and comprises a channel portion 16 having

jaws

17 and 18 formed at each end thereof, the jaws being designed to firmly grip the flanges of the I-beam. The

jaws

17 and 18 are formed from

elongations

19 and 20, respectively, eX- tending at right angles from the base 21 of the channel portion 16.

In the presentembodiment of the invention, the

portions

19 and 20 are offset as infacilitate the c devices for attaching cables .to the I-beam at Serial No. 164,270.

dicated'at 23 and 24, respectively, (Figs. 3

and et), so that the

jaws

17 and 18 resiliently engage opposite edgesof the flanges 11 and 12 when the member is attached to thefI-beam. The jaw' 18 is provided on its upper 3) with a sloped approaching surface 25 to kattachment of the member to Lugs or ears 26 and 27 projectfrom the portions 19 and the I-`beam. ing at right angles 20, respectively, j andcooperate with the bent-

overportions

28 and 29 ofthe

jaws

17 and 18, respectively, to firmly grip the flanges of the I-beam support in such manner that the channel portion 16 is suitably spaced from the face of the I-beam.

When attaching the member 15 to -an I- beaml support the jaw 17 is engaged with one of the flanges of the I-beam and the opposite end of themember is then pressed towards the I-beam until the jaw 18 engages the opposite flange thereof. It is obvious that due to the sloped surface 25, the jaw 18 Will move outwardly away from the jaw 17 when the member is pressed toward the I- beam and will tend to spring back to its normal position when it is in alignment with the flange 'of the I-beam, thereby cooperating withk the' jaw 17'tofiirmly gripthe I-beam support.

Aj resilient'clip 30 adapted to embrace a predetermined number of cables 3,1 is provided with oppositely disposed hook portions 32 designed to engage the flanges ofthe channel portion 16. The clip 30 is also provided with loop portions 33-33 by means of which a similar 'clip (not shown) embracing additional cables may be secured thereto.

When employingl the improved clamping to an I-beam support, a plurality of members 15 are attached suitable points therealong in the manner hereinbefore described. A predetermined number of cables are then placed in position' upon the base or web portions 21 of the tudinal axes parallel to each otherand prefi erably at right angles to the channel portion 16 of the supporting member. Resilient clips V30 are thenY placed Iaroundpredetermined numbers of these cables and spaced along lip (Fig. ,5,

engage the face of the I-beam members 15 with `their longi- I ion l the channel portions `from the supporting members and f devices embodying the features of the present invention, strands, cables or the like may be attached to supports very quickly and with out the use of any particular skill. Furthermore, the clips may be readily disengaged the' supported strands or cables may be quickly removed when desired. However, when installed the strands or cables are securely maintained in position.

Although the invention, as herein illustrated and described, is particularly adapted for attaching strands or cables to I-beam supports. it is obvious that the invention is capable of other applications within the scope or the appended claims,

Vhat is claimed is:

1. In a device for attaching a strand to a support, a member having a unitary channel portion and a pair of oppositely disposed i jaws for resiliently engaging the support, and

means resting on opposite vertical sides o said channel portion for securing the strand thereto.

2. In a device for attaching a strand to an I-beam support, a member having a pair of oppositely disposed resilient jaws engaging opposite flanges of the support, one of said jaws having a sloped lip to facilitate the attachment of the member to the support, a channel portion interconnecting said jaws and spaced from a face of said I-beam support and a resilient clip for securing the strand to the channel portion, said clip having a portion substantially embracing the strand and a pair of oppositely disposed hook portions engaging the flanges of the channel portion.

3. In a device for attaching a strand tov an I-beam support, a member having a channel portion and a pair or oppositely disposed jaws for resiliently engaging oppositely disosed flanges of the support, each of 4said jaws having a lug projecting thererom for engaging a ace of the I-beam to maintain the channel portion spaced from said face of the I-beam, and means resting on opposite vertical sides of said channel portion for securing the strand thereto.

4. In a device for attaching a strand to a support, a rectangular shaped element having angularly disposed lateral and longitudinal portions, the lateral portions having inwardly disposed extensions engaging the support, the longitudinal portions provided with inwardly curved upper edge surfaces, and

means having portions complementary to the inwardly curved edge surfaces and resting thereon for securing the strand to the element.

5. Inadevice for attaching a strand to a support, a member having spaced jaw portions ior yieldably engaging opposite edges of the support 'and a portion interconnecting the jaw portions, one or' the jaw portions having an outwardly extending inclined lip to facilitate the attachment of the member to the support, and means for attaching a strand to the interconnecting portion.
