CLAMP Filed Apil 25, 1929 Patented Mar. 25, 1930 UNITED-` STATES ALBERT, CLARKE, onnEsMorN'Es, 'IOWA criaurrjl L Si Application filed April 23,
The object of this invention is to provide an improved construct-ion for a clamp Which is useful for gripping and securely holding objects of various kinds and sizes.
A further object of the invention is to pr vide an improved clamp having an arm which is arranged for sliding adjustment and With these and other objects in vievv my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claim, and'illustrated in the accompanying drawings, in Which:
Figure 1 is a side elevation illustrating my improved clamp.l A
Figure2 is a plan View of the same.
Figure 3 is a sectional elevation on the line 3 3 of Figure 1, and illustrating particularly, the slidable arm.
Figure 4 is a sectional elevation on the line 4 4 of Figure 1 and illustrating particularly the pivoted arm.
Figure 5 is an elevation partly in section, illustrating the method of using the device as a clamp in connection with a bench or table.
The bar maybe of any desired shape in cross section. It is here shovvn as being of cylindrical shape and formed With a longitudinal groove 14. The aperture of the boss 18 is fitted to the cross sectional shapeof the bar 10 and suitable means may be providedto keep the arm 12 from turning on the bar. Such means is in this instance, a key 15 engaging the groove 14 and projecting Within a notch 16 openingfrom thev aperture of the boss. The free end of the standard 11 is bifurcated and aclamping arm 17 is pivoted 55 between its ends on a pin V18 extending through registering aperturesV in the bifurcated portion.
At its lowerfend the pivoted arm 17 is formed with a boss 19 having a threaded openingadapted to receive'ascrew 20. The screw 20 is formed With a head 21 through which an operating handle 22 is slidably mounted. Y j
The position of the pivoted arm 17 can be 65 controlled Vby operation ofthe screw 20, the inner end of which engages a face 23 formed at the adjacent'end of the bar 10` orl standard 11," as shvvn. The face 23 preferably is formed on a curve so that the screw`20 may 70 have a proper engagement therewith, irref sp'ectiveof th'ej position ofthe ,arm 17 by `which. it is carriefd.`
At the free end of the slidable arm 12 there is :tormed a clamping face 24, Whichmay be 75 of any desired size and shape. v
A clamping head 25 is formedwith a face adapted to coact vvi'th'the clamping face i24. The clamping head V25 is pivotally attached to the clamping arm17 by means of a pinor 80 rivet 26 extending. through spaced ears 27 onV thehea'd and through. an aperturein the'end portion of the arm. Y A
as a ytool by Wood Workers, mechanics, or v other artisans, ,for the purpose of clamping Inpractical use, the device may'befused l Y 'and holding anfobject or a plurality of objects. I Y
The arms `12and'17 areffirstadjusted softhat they Will be suiiici'ently spaced apart to "accommodate the o j ject or objects to be clamped between them. ,Y Then, pressure is applied by'turning the screw 2O through the handle 22 for the puri pose of moving the armI 17' through' an arc to 95 cause the clamping head 25 to approach/the clamping `face24.y This operation is continued until theobjeCt O ITObjects are engaged and Y securely gripped to. the desired' extent of Y pressure.
- '31 and bushing 32.
It is obvious that considerable force can be applied to the screw devices operating upon the pivoted arm and that the threaded engagement of the'screW 20 With the threaded boss 19 Will cause the parts to remain in any plolsition in which they may be placed manua y.
The pivotal mounting of Vthe clamping head 25 permits it to automatically adjust itself to the adjacent face of an object -to be gripped as the lever 17 is moved through* an arc. Y
The slidable mounting of the clamping arm 12 permits a Considerable range of adjustment and adds greatly to the Convenience and usefulness of the device.
The devicemay also be employed after the Jfashion "of a vdse, as illustrated inFigure 5 and for this purpose the slidable arm 12 is removed from the bar 10 by endWise move ment.
For this purpose, the device is used'vvith a bench or table such as is illustrated in Figure 5, which may include a top member 28, legs 29, and an apron 30.
An aperture 31 may beform'ed in asuitable portion of thezbench structure,'asfor instance, in oneofithe legs29. The aperture 31 is adapted to receive the elongated bar 10, but if desired, a separate bushing 32 may be employed in the opening 31 Within AWhich .the bar 10 is fitted for endvvisemovement. As here shown, a face plate 33 may Valso be m'ountedover the outer end of the opening n `When'the device istobe used in this manner, the bar 10 is inserted in the opening 31 until theclaniping head 25approaches a portion of the bench structure such as an edge of the top member '28 or a face of the apron-30.
An object to begripped is then inserted between the clamping fhead2`5fand the bench structure and pressure is applied by 'turning the screw 20`to cause a pivotal movement of Itis obvioust'hatthe bar 10 must fittightly Within the opening lin the benehstructure or in the aperture of Vthe boss 13 of the slidable arm 12 so that as pressure isfap'plied, a binding engagement will 'be '.producechvvhich will. prevent relative longitudinal movement gf the bar k1'0 with .respect .to Vthe Othermemer. I `have produceda clamping device which is relatively 'inexpensiveand ivhich is eHective yin-use'ior a variety loipurposes for seadapted for engagement With the adjacent end of the bar for forcing the other end of said arm toward the coacting arm, said bar being formed With an arcuate face for engagement of the end of the screw device at various positions of the pivoted arm.
