' CONCRETE-FORM.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed June 12, 1915. Serial No. 33,799.

To all whom it may concern:

Be it known that I, STEWART R. MOKAY, a citizen of the United States, residing at East Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Concrete-Forms, (Case B,) of which the following is a full,

clear, and exact description.

This invention relates to forms intended for use in building construction of the monolithic concrete type, wherein. the forms generally comprise vertical posts with intermediate panels which with the posts provide a surface against which soft concrete may be laid.

Theinvention to which this application relates resides in a unit form of a construction which will enable successive units, com- "prising vertical posts and intermediate panels, to be conveniently assembled and placed in operative relation to each other with accuracy,

Generally speaking, the invention comprises the elements and combinations thereof Fig. 1; Fig. 3 is a transverse section of a form showing one method of holdingplates in position Fig. 4 is a fragmentary sectional view showing another form or method of holding the plates in place, the sectional view corresponding to the line 4-4 F1g 1;

Fig. 5 is a. perspective showing the manner in which two unit forms may beunited. Fig. 6 shows the same parts as shown 1n Fig. 5 but in separated condition; and Fig.

7 is a partly sectional view on the line 7-'7 of Fig. 1. I

In general it may be explained that my invention relates to a form which is to be erected in proper position with respect to the foundations of a building for the purpose of forming the superstructure of monolithic concrete.

t In the construction herein proposed the form may be dismantled by removing its component parts and the same form may be again utilized and repeatedly utilized so long as the material itself will last.

My construction embodies vertical posts which are spaced apart and receive a series of panels between them which when' assembled form a surface against which soft eons crete may be laid. v The distance which these posts may be spaced apart is not material to this invention, the distance being chosen to provide what maybe a convenient space so that the panels are not so large as to be unwieldy to handle. The number of elements,

that is to say, the number of posts in series,

will depend entirely upon the length of the wall construction which is to be erected. In the present instance I have shown two, which will serve to illustrate the manner of their erection and the manner of their cooperat1on with the panels;

As I have shown it. each unit comprises two vertical posts including each what I may.

term side members 35 and 36. As shown, these side members are angle irons. To the top and bottom of these side members 35 and 36 transverse members 37 and 38 are secured.

. Preferably these members 37 and 38 are angle irons or channel members, one flange of the member 38-lying against and extending along the forward angular portions of the members 35 and 36. These members are-riveted to each other, so that there is formed a rectangular substantially rigid structure. Each unit is formed the same and the rearwardly extendingflang'es 35 and 36 of each side member 35 and 36 are provided with openings, which openings will be in alinement when succeeding sections are brought into alinement. The sections may then be secured together by means of bolts and nuts,

as indicated at 39. or another convenient form of fastening device which I will presently describe.

The webs or flanges 36 and 35 may be provided with pivoted retaining member such as shown at 4:0, and more plainly shown in Fig. 4.

' The panels 41, which may cooperate with the unit construction thus described. may be variously formed, but when the side members 35 and 36 ofthe-unit are formed of angle irons, as heretofore described, the panels 41 will be formed at each end with an extending tongue l2, whichwill be adapted to lie against the inner surface of the front 42 at both ends of the plate, and so will press the panel 2 firmly against the side members of the unit. The manner of cooperation between the retaining member and side member of thennit will be clearly understoodsun , the interior flanges of the units 35 and 36 will lie flush, so as to form a plain surface against which concrete may be deposited.

It will be desirable to place the l'l'lGllil'iQlS 43 and attach them to the inner facing of the 'flanges of the side members 35 and 36, to 'bring the surface of these inner flanges to lie flush with the inner faces of the panels 42.

It will be seen that the several members 35, 36, 37 and 38 are permanently secured together,- forming a frame which I have termed a unit. These various frames will be assembled with respect to each other in proper manner to form the wall or surface which is to be molded of concrete.

In Fig. 3 I have shown a modified form of construction by which the panels 41 may be held with respect to the frame or unit; and, also, I have shown another modified form of frame. In this construct-ion the side pieces are formed with an individually extendlllg outer flange 45.

This outer flange is adapted to receive an angular shaped retaining member 46, the retaining member engaging the flange 45 and also engagingthe e X- tension 42. The member 46 is chosen to be of such size that it will fit tightly and so press the panels 41 firmly against the to nuts and bolts are difficult to keep together when not in use. and I have, therefore. devised a means which retains all the parts of the clamping means together.

At 47 and at 48 are indicated two of the rearwardly extending flanges of adjacent unit sections. In the member 48 there is formed a slot 49 having an enlarged head part 50. In the member 47 there is an opening in the form of an elongated slot 51. Through this slot there extends a member 52 which has a head portion 53. The head portion prevents the member 52 from passing throughthe slot 51, and at one end of the member 52 there isa head 54 which also prevents the member 52 from passing through the slot. This member 52 may be formed in any desired manner, but preferably it is formed of two pieces of material riveted together with the inner ends turned up to form the head 53. j

The member 52 is formed with the slot 55' which is adapted to receive a wedge 56. This wedge is provided. with heads or pro-- j ections 57 at each end thereof, so that it can not move out of the slot 55. The opening 51 is of greater diameter than the head53, so that the head 53 may be slipped through the opening 50 when the members 47 and 48 are brought together. The wedge will then be moved into the slotted portion 48 and the wedge driven into the slot 55. This will hold the members 47 and 48 tightly together.

It will be seen that when the members 47 and 48 are disengagedthe member 52 and the wedge are carried by the member 47 and cannot be removed'therefrom'unless the member 52 is willfully mutilated for the purpose of removing it.

There will, of course, be asuffi'ci'ent number of these retaining members carried by each unit or frame, so that the adj acentunits may be securely fastened together.

Having described myinvention, I'claim i. In a formof the character described, a unit comprising side membershaving flanged portions and end members to which the side members are secured, one of'said side members in the flanged portion thereof being provided with a slot, aretaining member extending through said slot, said retaining member being provided with a head, said retaining member also having a slot and a wedge in said slot, means-for retaining the wedge in said slot, the flanged portion'upon the other side of the side portion of said unit being provided with openings which are adapted to receive the head of a retaining member and a slot extending from said opening into whichthe retaining member may slide when the successive units areassembled, p'anel members extending. between the side members and means for securing the panel members independently to the side members.

2. In a form ofthe character described, a plurality of units, each of said units comprising side members and end members to which the side members are permanently secured, means for securingthe side members of adjacent units together, and panels extending between the side members of each unit, and means for holding said panels in position with respect to the side of the unit.

3. In a form of the character described, the combination with a plurality of units, each of said'units comprisingside members and end members which are permanently secured together, the side members having flanged portions, means engaging the side portions of adjacent units to hold the units together, panels extending between the side members of each unit, andmeans cotiperating with'the side members and thepanels for holding said panels in position with respect to the side members of the units.

4. In a form of the character described, a plurality of units each of said units compris ing sideinembers'and end members to which lee the side members are permanently secured, means for securing the side members of adjacent units together, the side members of each unit having inwardly extending flanges, panels which cooperate with the said flanges, and means for holding said panels in engagement with the flanges of the side memers.

5. In a form of the character described, a plurality of units each of said units comprising side members and end members to which the side members are permanently secured, means for securing the side members of adjacent units together, the side members of each unit having inwardly extending flanges, panels having tongues at their ends the said tongue portions cooperating with the flanges of the side members, and means for holding each panel independently in engagement with the flanges of the side members.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
