62 05527 Z9222 v BY jffdiwf Patented Apr. 8, 1952 UNITED STATES PATENT OFFICE INSERTING TOOL Foit s'r'r-Ai This George Erb'e, Jersey City, N; 'J. Application January 27, 1951, Serial No. 208,200 1 claim. (01. 24-'-20'1) This invention relates to a tool for inserting tie rods on building wall forms.
It is an object of the present invention to provide a quick attachable and detachable tool adapted for connection to a tie rod whereby to locate the tie rod in hole in the opposite form from which it is connected in order that the forms can be pulled or pushed and spaced properly from one another and wherein the inserting tool can be readily released from the tie rod by a simple movement of the tool over the head on the tie rod.
Other objects of the present invention are to provide a tie rod inserting tool for forms used in wall constructions which tool is of simple construction, easy to attach to the tie rod, inexpensive to manufacture, has a minimum number of parts, strong, durable and efficient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of the inserting tool for the tie rods embodying the features of the present invention.
Fig. 2 is a longitudinal sectional view taken on line 2-2 of Fig. 1.
Fig. 3 is a top plan view of the attaching portion of the tool.
Fig. 4 is a fragmentary sectional view of the portion of the tool which receives the tie rod with the enlargement of the tie rod disposed in the end of the tool and in place to effect the inserting operation thereof.
Fig. 5 is a longitudinal sectional view taken on line '55 of Fig. 1.
Referring now to the figures, I0 represents an attaching part of sleeve formation throughout a greater extent of the same and having a body portion ll. l2 through which a cable cord 13 extends. The end of the cable cord is folded, as indicated at I4, whereby to hold the cable within the attaching part H1. The sleeve portion is integral with the body it and extends forwardly therefrom, as indicated at l5. In the sleeve portion is an elongated slot 16 which extends along one side of the portion and laterally, as indicated at H, across an end formation [8 in the end of the sleeve. The slot 46 has transverse and inclined notches l9 and 26 adapted to receive a head 2| of a tie rod 22. This head 2| is fixed to the tie red by a riveted connection. The head 2| will The portion ID has a central opening pass downwardly through the laterally extendin notches of the slot l6 and presented to thesani-e in the manner as shown in Fig. 2 and upon draw ing the rod forwardly, the head 2| will come to rest against the end formation l8. An upwardly struck stop portion 23 will hold the tie rod against rearward displacement in the attaching member I0.
The cable l3 has at its opposite end, a ball 24 adapted to pass into a sleeve or handle 25 with the cable l3 extending through slot 26. Stop projections 21 extend inwardly from the sleeve wall 25 so as to retain the ball against outward displacement from its center position. The handle 25 can be grasped to straighten the cable l3 and place an inserting force on the gripping or attaching piece IE! in order to insert the tie rod 22 into hole in opposite building form for proper engagement therewith. Thereafter the attaching piece It] can be readily pivoted so that said handle 25, but will further allow the handle 25 to be turned at angle as also shown in Fig. 5, that is, from l3 to I3. It will be further seen that slot 26 enables the cable l3 to reach position I 3 as shown in Fig. 5, thereby allowing handle 25 to pass through a hole which may be of an inch in a form assembly.
In the use of the attaching piece it the head is aligned with the downwardly and forwardly inclined lateral notches l9 and 2!) in order to properly present the same to the opening IS, the tie rod 22 can be pulled through the slot [1 for engagement with the end formation l8. With the tie rod in place, an attaching piece H] can be tilted to the side and pushed out of engagement with the head 2| allowing the head thereby to pass outwardly from the notches l9 and 20.
It should now be apparent that there has been provided a tool for use with tie rods that can serve to enter or insert the same in wall forms and which can be attached and detached from the tie rod in any easy manner.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
Having thus set forth and disclosed the nature of my invention, what is claimed is:
A tie rod inserting tool adapted for connection with an enlarged head on a tie rod comprising a sleeve member having an elongated notch extending from the attaching end thereof with laterally downwardly and forwardly extending notches for receiving the head on the tie rod whereby to permit the forward movement of the head through the attaching sleeve, said longitudinally extending slot being adapted to accommodate the tie rod and having a width only slightly larger than the diameter of the tie rod and an end formation on the sleeve member having a slot to accommodate the tie rod, said end formation serving as an abutment for the enlarged head on the tie rod, and a transverse abutment lying forwardly of the laterally extending notches of the elongated slot and disposed on the wall opposite the said elongated slot whereby to ;prevent the rearward displacement of the enlarged head of the tie rod while the tie rod is axially aligned with the sleeve member.
