Application mea March 29,1926. serial no. 98,152.

This invention relates to a material clamp for retaining papers, pads, samples and the like, and concerns itself primarily with a structure comprising -a plurality of independent clips or holding fingers which will independently yield to compensate for 1r regular thicknesses in the clamped material, and operating means adapted for simultaneously operating all of the clips if desired.

The invention comprises the novel structure and combination of parts hereinafter described and more'particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate certain preferred embodiments of this invention, and in which similar reference numerals refer to similar features in the different views,

Figure 1 is a top plan view of a clamp Flgure 2 is an enlarged fragmentary sectional view upon the line II--II of Figure 1.

Figure 3 is an enlarged fragmentar' sectional view taken upon the line II III Figure 4 is top plan view of amodified form of clamp.

Figure 5 is an end elevational view of the modified structure.

Figure 6 is a top plan view of the base plate of the modified structure.

Figure 7 is a sectional view upon the line .VII--VII of Figure 4.

HIn referring to the drawings, especially my improved clamp comprises a base or support 1, the to end of which ma be thickened by a hea plate 1'?. A plurality of independently yieldable clips or fingers 2 are mounted u on the base 1. In the present instances, t e clips 2 are formed as integral fingers of a plate 3 which is secured to the base 1. This plate 3 is bent over upon an arc and the top end is inclined downwardly into contact with the base 1;.the clips or lingers 2 being formed by slitting the upper portion of the plate at predetermined intervals. Preferabl a leather mat 4, or the like, is applied to t e upper face of the plate where the clamped matter is located. T he clips 2 are sufficiently resilient for clamping purposes, and they may be independently released by forcing the nail of a linger thereunder, or they may be simultaneously actuto Figures 1 and 3, it will be observed that ated to releasing positions by a bar 5 extending lengthwise beneath said clips. The bar `5 may be secured to the end clips by a tongue and socket connection 6, as shown 1n Flgure 3. A rigid bail or handle 7 is connected to the bar 5 for actuating the same, the arms 7n of the bail extending through apair of the slots between the clips. The arms "7a of the bail are adapted to fullcrum upon the rear end of the slots. Consequently, by 'actuating the bail downwardly, the cllps or fingers 2 are simultaneously elevated for releasing the clamping action thereof. l

In Figures 4 to 7, the base'8 is provided with pairs of spaced upstanding hin e ears or lugs 9. To each pair of lugs, t ere is pivoted a clip 10. These clips have depending lugs 11 intermediate their ends, and a -pivot rod 12 extends through the ears 9 and lugs 11. Springs 13 are coiled around the rod 12 under each clip. One end of each spring bears against the base, while the other end bears against the power arm of the clip. It\wil1 be 'noted that the front or clamping ends of the clips 10 cooperate with the forward edge of the base 8 which is sli htly turned up, and the rear ends form nger pieces which may be manually and independenly depressed for elevating the clamping en s.

The clips 10 may; however, be simultaneously released from clamping action by a bar 14 which extends under the clamping handle 15 pivoted or fulcrumed intermediate its ends upon the pivot rod 12. Consequently, as the handle 15 'is depressed, the bar 14 will be elevatedl for simultaneously releasing the clamping action of all of the clips 10.

It will be evident that in use, in cases certain of the articles may be released Without disturbing the others.

I am aware that many changes may be made, and numerous details of construction -may be varied through a wide range Without departing from the principles of this arms of the clips and is provided with a invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1 In a clamp, a support, a plurality of independently operable alined clips upon said support, a bar extending beneath said clips for simultaneously actuating the same, and mea-ns for actuating said bar.

2. In a clamp, a support, a plurality of n independently operable clips upon said support, a bar extending lengthwise beneath said clips, and means for actuating said bar.

3. In a clamp, a base, a plurality of independently operable clips upon said base, 15 a bar extending beneath the forward parts of said clips and an operating lever attached to said bar "for simultaneously actuating said Y clips. I'

4. In a clamp, a base, a plurality of in- 20 dependently operable clips upon said base, each clip having an operating handle, a bar extending lengthwise beneath said clips and an operating lever connected to said bar.

In testimony whereof I have hereunto fub- 25 scribed my name.

HARRY S. JONES.
