Patented Jan. 6, 1948 UNITED STATES PATENT OFFICE TIE DEVICE FOR WALL FORMS Arthur H. Symons, Chicago, Ill.

Application June 24, 1944, Serial No. 541,921

8 Claims.

through a hole in the other form and the enlargement is disposed adjacenta single reenforcing beam, such as a stud or wale on the outer face of said other form; (2) a bracket which fits against, and is secured to, the reenforcing beam; and (3) a member which is slidably mounted on the bracket, is adapted when slid in one direction to interlock with the enlargement, and serves when in its operative position wherein it is in interlocked relation with the enlargement to connect the bracket to the rod and thus maintain the other form in its proper or desired position with respect to the one form.

One object of the invention is to provide a tie device of this type which is an improvement upon, and has certain advantages over, previously designed devices for the same purpose, including that which is disclosed in, and forms the subject matter of, an application for United States Letters Patent filed by me on even date herewith, and serially numbered 541,920.

Another object of the invention is to provide a tie device of the aforementioned type which is characterized by simplicity of design, cheapness of construction and facility of assembly and dismantlement.

Another object of the invention is to provide a tie device of the type and character under consideration in which the enlargement at the extremity of the end of the rod that extends through the form with the reenforcing beam is in the form of a U-shaped 100p, and the slidably mounted member is in the form of a wedge shaped plate and has a bifurcated small end which when the member is in its operative position straddles and spreader rod extends through a transverse aperture in thereenforcing beam and the bracket and wedge shaped member are so constructed and arranged that when the member is in its operative position wherein the small end thereof straddles the outer end of the loop no forces are set up tending to roll or rock the reenforcing beam relatively to the adjacent form.

A still further object of the invention is to provide a tie device which is generally of new and improved construction-and effectively and efliciently fulfills its intended purpose.

Other objects of the invention and the various advantages and characteristics of the present tie device will be apparent from a consideration of the following detailed description. 1

The invention consists in the several novel features which are hereinafter set forth and are more particularly defined by claims at the conclusion hereof. I

In the drawin'gswhich accompany and, form a part of this specification or disclosure and in which like letters and numerals of reference denote corresponding parts throughout the several views: 7 V a Figure 1 is a fragmentary perspective view showing a pair of laterally spaced upstanding wall forming forms having applied thereto a tie device embodying the invention;

Figure 2 is a perspective view of the wedge shaped member; a

Figure 3 is a perspective View of the combined tie and spreader rod;

Figure 4 is a perspective View of the bracket;

Figure 5 is a horizontal section showing the device in its operative position; and

Figure 6 is a vertical section taken on the line 6-6 of Figure 5 and illustrating in detail the manner in which the wedge shapedm'ember coacts with the outer end of the loop and the bracket so as to lock the bracket against'longitudinal displacement in either direction relatively to the combined tie and spreader rod. I

The tie device which is shown in the drawings constitutes the preferred form or embodiment of the invention. It is adapted for use in connection with a pair of upstanding Wallforming forms F and F and comprises a combined tie and spreader rod I, a bracket 8 and a wedge 9. The forms are disposed in laterally spaced relation and are adapted to have concrete poured therebetween for wall forming purposes. As well understood in the art, the forms are removed after hardening or setting of the concrete. The form F comprises a comparatively thin flat composite wooden panel I and an exteriorly disposed wooden reenforcing beam f in the form of a, stud or wale. Such beam extends horizontally, as shown in Figure 1. It serves not only to reenforce the panel 1 but also to align the planks thereof and suitably secured by nails or other attaching de vices (not shown) to the outer face of said panel f.

The combined tie and spreader rod 1 extends horizontally between the two forms F and F and is circular in cross section. It is disposed at right angles to the forms and has one end thereof extending through the form F and anchored to the latter in any suitable manner. The other end of the rod extends through a hole I in the panel 1 and a horizontal transversely extending aperture f in the reinforcing beam f The outer extremity of the end of the combined tie and spreader rod 1 that projects through the aforementioned hole and aperture projects a com paratively small distance beyond the outer face of the reenf-orcing beam and is bent laterally and then inwards to form a loop Ill. The aperture f in the reenforcing beam f is in alignment or registering relation with the hole 7 in the panel J. The aperture and hole are of sufficient width to permit the loop ID to pass therethrough in connection with assembly of the combined tie and spreader rod 1 with respect to the form F. The portion of the rod that is directly inwards of the hole I in the panel 1 has a, smooth cylindrical contour and possesses no enlargement, washer or crosspin in abutment with the inner face of the panel 1''.

' The bracket 8 is in the form of a plate metal stamping and fits against the outer face of the reenf-orcing beam F It is horizontally elongated and consists of a vertically extending wall H and a horizontally extending wall l2. The wall II fits flatly against the outer face of the reenforcing beam f and is fixedly secured in place by way of a pair of lag screws I3. The shanks of the screws extend through horizontally elongated slots [4 in the ends of the wall II and project into the outer portion of the reenforcing beam. The central portion of the vertically extending wall ll of the bracket is provided with a horizontally elongated slot I5, which is in registry with the outer end of the transverse aperture f in the reenforcing beam f and has the loop In of the rod I projecting therethrough. When the device is assembled, the loop H), as shown in Figures l, 5 and 6, is disposed horizontally and projects through and outwardsof the horizontally elongated slot I5 in the central portion of the wall I l of the bracket. The horizontally extending wall I2 is formed integrally with, and projects outwards from, the upper margin of the vertically extending wall ll. The central portion of the wall I2 is provided with a slot l6 and this extends at right angles to the wall l2 and is vertically aligned with'the central portion of the loop receiving slot in the wall I I. As shown in Figure l the inner end of the slot I6 terminates adjacent the outer face of the vertically extending wall I l of the bracket. In addition to the walls H and 12 the bracket 8 comprises an upstanding metallic lug [1. This lug is welded to, and projects upwards from, the central portion of the upper margin of the vertically extending wall I l of the bracket and is so positioned that the outer face thereof is flush with the outer face of said wall ll.

The wedge 9 is stamped from flat plate metal and is mounted for vertical sliding movement in the slot 16 in the central portion of the horizon- 4 tally extending wall 12 of the bracket. It is ar-' ranged so that the small end thereof projects downwards. The slot I6 is of such length that when the wedge 9 is driven downwards the upper end of the wedge fits snugly in the slot I6. Said small end of the wedge is provided. with an elongated longitudinally extending notch IS in order that it is bifurcated and embodies a pair of laterally spaced arms l9. When the wedge is driven downwards while the loop l0 projects through the slot I5 in th vertically extending wall H of the bracket the arms I9 are brought into straddled relation with the outer end of the loop ill with the result that the wedge so connects the bracket to the rod that it is locked against longitudinal displacement in either direction relatively to the rod. When the wedg is in its operative position the outer end of the loop It] is disposed in the upper end of the notch [B and the inner edge of the wedge fits flatly against the outer face of the lug and the vertically extending wall I l of the bracket. The width of the upper end of the notch I8 is the same as the diameter of the combined tie and spreader rod with the result that the outer end of the loop fits snugly in the upper end of the notch when the wedge is in its operative position. The lower end of the notch I8 is downwardly flared in order to facilitate entry of the outer end of the loop into it during downward driving of the wedge. When the wedge is in its operative position the upper portion of the inner edge of the wedge engages the outer face of the lug I! and the lower portion of the inner edge of the wedge engages the outer face of the vertically extending wall ll of the bracket with the result that the wedge is effectively held against rocking or tilting relatively to the bracket. By reason of the fact that the loop equipped end of the rod 1' extends throughthe transversely disposed aperture in the reenforcing beam f the forces which result from driving of the wedge 9 into its operative position do not tend to roll or rock the beam relatively to the panel 1. When it is desired to remove the form F the wedge 9 is driven upwards until it is disengaged from the loop III. In order to maintain the wedge in slidably connected relation with the upper side wall of the bracket the lower end of the inner arm I9 is provided with a crosspin 20. The length of this pin is slightly greater than the width of the slot H5. The width of the space within the loop I0 is such that the pin is free to pass through the loop when the wedge is shifted upwards in connection with releasethereof from the loop.

When it is desired to use the tie device the form F is first erected or properly positioned and the adjacent end. of the combined tie and spreader rod 1 is anchored thereto. Thereafter the form If is positioned in opposed relation with the form F and is manipulated so as to position the hole I in the panel f in registry with the loop ID of the rod 7. After such manipulation of the form F the latter form is shifted bodily towards the form F until. the loop I0 is disposed directly outwards of the horizontal slot I5, in the central portion of the vertically extending wall ll of the bracket. In connection with inward shift of the form F. the wedge 9 is held so that the small or lower end thereof is above the slot l5. After proper positioning of the form F the Wedge 9 is driven downwards so as to bring the bifurcated lower end thereof into straddled relation with the outerend of the loop 10. and, its upper end in seated relation with the slot l6; As heretofore pointed out, when the wedge is driven'into its operative position the upper end thereof fits snugly in the slot l6 and when the device is fully assembled the form F is locked or held against longitudinal displacement in either direction relatively to th combined tie and spreader rod 1. After assembly of the device concrete is poured into the space between thetwo forms. After hardening or setting of the concrete the forms are removed from the concrete formed wall. In connection with removal of the form F the wedge 9 is driven upwards until it is disengaged from the loop l0. Thereafter the form F is shifted laterally away from the wall. After removal of the form F the end portion of the rod 1 having the loop I0 is severed from the central portion of the rod which is embedded in the wall.

The herein described tie device effectively and efiiciently fulfills its intended purpose andmay be assembled and dismantled with facility. It is essentially simple in design and construction and hence may be manufactured at a low and reasonable cost. By reason of the fact that the wedge when in its operative position is locked to the bracket and has its bifurcated end in snug straddled re ation with the outer end of the loop on the rod there can be no slippage whatsoever of the form F with respect to the rod. The device is adapted or designed to be used with like devices in holding the two forms against separation during a concrete pouring operation.

Whereas the device has been described as comprising a single bracket and a single wedge at one end of the combined tie and spreader rod it is to be understood that the other end of the rod may be connected to the form F by providing said other end of the rod with a loop and utilizing in connection with such loop another bracket and another wedge, as shown in Figures 1 and 5. It is also to be understood that the invention is not to be restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is:
