Application April 13, 1945, Serial No. 588,162 2 Claims. (Cl. 25-131) 1 2 The invention relates to a, releasable clamp and spacer device, and more especially to a clamp and spacer for knockdown concrete forms or false number thereof, comprises a tubiform spacer member I2, preferably made from a, single sheet of stiff material, such as metal, which is rolled on itself into tube form, of any required length, as best seen in Figure 1 of the drawing, This member I2 is adapted to be disposed between the opposed portions A of the form, so that its ends work. The primary object of the invention is the pro vision of a device of this character, wherein knockdown false-Work or forms for concrete con struction work can be releasably clamped to telescopically wedge onto conica1 shaped center gether and spaced properly for receiving the con knobs I3 of abutment washers or disks I4 having crete in the erection of the construction work, 10 bearing against the portions A and loosely fitted about the shank I5 of a hook headed clamp fol the device being of novel and unique construc lowing the character of a bolt, the hook head tion, it being easily iitted in place and removed, being denoted at I6. This shank I5 of the clamp with dispatch without requiring skilled labor. or bolt 'at the end portion remote from the head Another object of the invention is the provision of a device of this character, wherein it is devoid ,15 I6 has removably tapped thereon a binding nut I 1, which is adapted to play against a washer I8 of a complicated assembly, and possesses few on the said clamp or bolt and rests against one parts, which are adapted for inter-fitting with of the strips or rails II next thereto, the shank each other, holding the forms firm and secure to I5 being passed through suitable clearances, these the construction work. A furtherobject of the invention is Vthe pro 20 being denoted generally at I9, as provided in the form portions A and the rails II aligning with vision of a device of this character, which is sim the clamp or bolt when the forms are set up in ple in construction, thoroughly reliable and efli assembled relation for concrete construction cient in operation, strong, durable, it being re work, The head I6 of the bolt or clamp is hook -useable infinitely, enabling the forms to be knocked down and set up with dispatch and ease, 25 locked with the rail II next thereto, so that the shank I5 will not turn when the nut is tightened and inexpensive to manufacture and install. or slackened thereon in the application and re With these and other objects in view, the in moval of the device. ` vention consists in the features of construction, The device when applied to the false-work or combination and arrangement of parts as will be hereinafter more’fully described, illustrated 30 forms will iirmly and securely hold them in place in the accompanying drawing, which shows the preferred form of embodiment of the invention, and pointed out in the claims hereunto appended. In the accompanying drawing: Figure 1 is a, fragmentary sectional View through 35 and the opposed sections thereof in their proper spaced relation to each other for the pouring of the concrete wall formation, and such device can be readily removed for the knocking down of the false-work or forms from set up condition. What is claimed is: 1. A device of the kind described, comprising a knock-down assembly of concrete forms, show ing the device constructed in accordance with a substantially tubiform spacer member made the invention applied. from a single sheet of metal and rolled on itself Figure 2 is a fragmentary elevation of the de vice looking toward the same at substantially 40 into tube form, abutment washers at the ends of the member and having conica1 center knobs in right angles to that position shown in Figure 1. terñtting the ends of said member, `and a work Figure 3 is an end view of the spacer member clamp removably passed through the washers and of the device. _ member and clamping these in spacing relation Similar reference characters 'indicate corre sponding vparts throughout the severa1 views in 45 to the work. f 2. A device of the kind described, comprising a. substantially tubiform spacer member made Referring to the ydrawing in detail, A desig-` from a single sheet of metal and rolled on itself nates generally opposed portions of a knock into tube form, abutment washers at the ends of down concrete form or false-work, for erecting a concrete wall or the like, and each involves as 50 the member and having conical center knobs in terñtting the ends of said member, a work clamp usual the tongue and grooved interlocking fac removably passed through the washers and mem ing boards I0, which are of the required thick ber and clamping these in spacing relation to ness, widthand length according to the neces the work, a working engaging hook on one end sary work requirements, while at the outer sides of these boards I0 are crossing strips or rails II, 55 of the clamp, and an adjusting nut carried at the other end of said clamp. which make contact therewith. the drawing. ~ The device constituting the present invention, there being employed anyrequired or selected ’ » EMANUEL CORNELLA.
