Application May 31, 1938, Serial No. 210,806

3 Claims.

This invention relates to an improved combination spacing and form supporting member which is especially adaptable for use with precast concrete joists.

One of the principal objects of the improved device of this invention resides in the provision of means for economically producing a device of the kind referred to for temporary use in maintaining precast concrete joists in desired spaced 10 apart relation and vertical.

A still further important object-of advantage is the provision of means for temporarily supporting floor 'form boards as a concrete floor is poured and at the same time maintaining the 15 supporting joists vertical and in spaced apart relation.

Another and further object of importance and advantage resides in the provision of means for detachably securing the improved device to the lower bead of the joists with which the device is used.

Still another object of advantage and importance is the provision of means for quickly disengaging the securing hasp preparatory to removing the device from engagement with the joists.

A still further object of importance and advantage is the provision of means for preventing lateral tipping or tilting of the device when it is in engagement with the joists.

An additional object of advantage and importance resides in the provision of means for adjusting the length or depth of the improved de- 35 vice.

Additional objects of advantage and importance will become apparent as the following detailed description progresses, reference being had to the accompanying drawing wherein,

Fig. 1 is a front elevational view of a spacing and form supporting member which embodies the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a sectional view, slightly enlarged, taken on line 3-3 of Fig. l. v

Fig. 4 is a vertical section, slightly enlarge taken on line 4-4 of Fig. 1.

As shown in the drawing:

The reference numeral Ill indicates generally 50 the horizontal form supporting portion of the improved device of this invention. In the preferred embodiment of the invention the form supporting member In is preferably constructed of two overlapping angle iron members as is best 55 shown in Figs. 1 and 3.

Projecting downwardly from each outermost end of the horizontal member I is a vertical member 12. The Vertical member 12 is preferably constructed of angle iron and may be an integral part of the horizontal member It). It is 5 to be noted that each end of the horizontal member at its upper edge projects outwardly beyond the face of the vertical members l2 to form a contacting point adapted to engage the upper portion of a joist as is clearly shown in Fig. 1.

Adjustably secured to each vertical member l2 and extending therebelow is a vertical extension I4. A plurality of bolt receiving openings I6 are formed in each downwardly projecting extension 14, as is best shown in Fig. 1.

' Provision is made for increasing or decreasing the length of the horizontal member ID by a plurality of registering openings l8 in each overlapping angle iron member. The openings l8 are preferably round or relatively short slots. Long slots are preferably not employed as they tend to weaken the member l0.

From the foregoing it will be apparent that the supporting structure which comprises the members l0 and I2 is in reality two substantially L-shaped members adjustably joined together. However, it will be apparent that where adjustability of the device is not desired, the entire structure comprising the horizontal supporting member and the two vertical end members may be formed from a single piece of material.

Hingedly secured to the lower end of each ver tical extension I4 is a securing hasp 20. The securing hasp 20 is preferably of L formation as is best shown in Fig. 1. When in operable position the hasp 20 extends outwardly from the vertical member l4 and thence upwardly as is indicated by the reference numeral 22. The upper edge 24 of the upwardly extending portion 22 of 0 the hasp 20 is curled inwardly as is clearly shown in the drawing.

Curled outwardly from the upwardly extending portion 22 of the hasp 20 is a lug 26. The lug 26 provides a means for facilitating removal of the device from its association with precast concrete joists. A pinch-bar, hammer, or any other suitable tool may be employed on the lug 26 for moving the hasp into a releasing position.

Rigidly secured to the extension [4 or the vertical member I2 is a contact member 28. The contact member 28 is adapted to engage a joist 3U slightly above the lower bead thereof, as is best shown in Fig. l.

The contact member 28 and the hasp 20 or u joists vertical and in spaced relation and alsofor supporting floor form boards for concrete floors and the like.

It will also be apparent from the foregoing that the improved device of this invention may be constructed to be used with conventional precast concrete joists positioned at predetermined" intervals or may be made adjustable to accommodate joists of various dimensions spaced at different intervals.

Itwill also be apparent to those skilled in the art to which the device appertains that numerous changes and alterations in construction and design may be made all without departing from the spirit or scope of this invention. Accordingly,'. it is understood, that the patent granted hereon is not to be limited to the preferred embodiment here disclosed nor in any other manner except as necessitated by the terminology of the appended claims when given the range of equivalents to which they may be entitled.

I claim as my invention: l.

1. A combination spacer and. form support comprising a substantially inverted ,U-shaped member, a contact member secured to eachvertical portion of said U-shaped memberintermediate, the ends thereof, outwardly projecting contacting members at the, upper end of each versaid joists for .maintaining said joists vertical,

a contact member secured to each vertical portionof said U-shaped member intermediate the ends thereof, and an L-shaped hasp hingedly secured to the lower end of each vertical portion of said U-shaped member, said L-shaped hasp being shaped to engage and grip a joist on the side furthest from said U-shapedmember.

3. A combination form support-and joist. spacing member comprisinga horizontalv member having a downwardly projecting portion at eachend thereof, a plurality of joist contacting members on each downwardly projecting; portion, saidi contacting members being adapted toengage a joist at the top,- bottom, and intermediate portions thereof, and means at the bottom of each downwardly projecting portion for removably securing said member'to a pair ofspaced joists,-

saidv means including hasp members,- eaclx ofsaid hasp members having portions adaptedto extendacross the. bottom of a joist and: thence extend-- ing upwardly and being adapted to engage and; grip the vertical surface of the lower portion of said joist.
