STRAP TIGI'I'IENING AND HOLDING DEVICE.

This invention relates to adjustable fast- This invention has utility as a clamp for assembling and holding a binding strap or strip,

In bringing this plate 3, say of hoop iron, which may be of 51X- teen or eighteen gauge. hoop iron about the group desirable to have such wing this of panels it is t to a taut ightening,

herein disclosed conibuckle or into use the hoop iron 3 has portion 6 bent back on itself to provide a an ordinary nail o duced. By having loop 7 protruding through Into this 100137, a pin, as ike 8, may be intro n 6 of the may place a.

panels as extending through-the opening 5 and "back. along. the panel, this end. 6 is clamped by the under side of the strap against. the panel and there is minimized any tendency of this end of the strip to work loose fromthe base 4. i

Rising from this plate 1 of the main base is a pair of brackets 9 mergin toward the frame 5. These brackets have earing-providing openings 10 in is provided with a slot 12 through which may extend end portion 13. As threaded through the slot 12 this end portion 13 may even protrude through the slot 12 to have, bent over portion 14L. This threading of the end of the strap 3 into the slot 12 ofthe pin 11 may be as the pin 11 is thrust from one opening 10 to the other or' after the pin 11 has been inserted in both openings 10 as rising from the plate 4.. WVhen so assembled and with this end 13 of the strap 3'threaded therewith, its squarehead 15 engaged by a wrench or other tool, and turned to wind the strap 3 into taut. condition for effectively clamping; or binding the column panels-in as sembl'ed relation. The pin 11 may be keyed against removal from the base by nail 16 or other pin fastener through opening 17 to thereby serve as a key. In the winding of this strip 3 about the pin 11, if such winding be over the pin 1.1 instead of under, there is more positive holding action for this fastener into snug position against the panel. Openings 18 in the head 15 may receive pin or nail 19 of a length to engage the base 4 and hold the pin fromunwinding. The nail 16 may be of such length as not only to be used as key but to serve to prevent unwinding of the pin 11 by engaging the plate 4.

In the tightening of the strap 3 there is in many instances requirement for rather close clamping adjustment to be obtained with speed; To this end the head 15 of the pin 11 is provided with a ratchet portion 20 with which may be engaged by pawl 21 having trunnion 22 extending through opening 23 in one of the brackets 9. The operator finger on the pawl as the pinis being set up to'urge the pawl into a ratchet seat. Bythis means there is. close angular adjustment over a wide range for this pin 11. The trunnion 22 is of such size that by a stroke from a hammer it may be sentinto the pin 11 may have opening 0 with the keyQpin or nail held in openings while the lead intothe pin;11 (if the strip 3 261 Tilismeans that in the connections to thisdexzice such maybe at acorner or even threughslot or opening bridged by this de- 16 r fllhis' fastener may serveas a panel assembly ,for forms othenthan columns. Girder panels 27 have their open topportions sg iaced bybraces 28 an d the strap 3 withthis base i, 9, l0 and 11 connected for clamp assembly of such girder forms.

VJ hen the concrete has been poured into the structure and sutlicient time has elapsed lorthe desired set, it is only necessary for the workmen to come to :the device of this disclosure, knock out nails 8 and the device is at once free, as the strap 8 is thus loosened from the panels. The strap 3 may be discarded or it may be ,re-used as its condition may warrant, It is thus seen that there is disclosed herein a simple, effective and substantial fastener of ample tightening capacity which is capable of time saving use vin assembling and knocking down forms inconnection with poured structures.
