- the invention relates to a tool for applying ties to concrete reinforcing bars and seeks to provide a simple and effective form of tool which may be applied to the tie and the reinforcing bars when and after the bars are set in forms, for closing the tie on the bars and binding them securely together.
- bars are placed in the forms before the concrete is poured, and spaced at intervals to reinforce the concrete, the bars usually crossing each other at approximately right angles, although sometimes they are secured in parallel connections, and ties are used to securely connect the bars where they cross or meet.
- tools for applying ties to concrete reinforcing bars be provided with a hook to pick up the bars when they are lying on the bottom of the form so that the tie may be readily placed within the tool or in place on the bars, and that the tool be so constructed that a single movement will set the tie firmly on and around the bars so that they will be readily connected by the tie.
- Adjustable features whereby the tool may be readily changed to conform to the various sizes of ties and bars so that one tool will apply all ties on a structure, is also very desirable.
- the present invention seeks to provide an improved tool which may be applied directly to the ties and the bars of concrete reinforcing for closing the ties on, and Se curely connecting the bars.
- ties have been applied to the bars by hand and closed with a hammer or other like tool which consumes considerable time and does not produce the desired results, as with hammering and the like the ties cannot be closed with suificient snugness to grip the bars and hold them rigidly in place, but with a tool that is fitted around the bars and the tie, the tie may be closed with a single stroke of the lever of the tool and the ties are gripped on the bars with sufficient force to grip and hold the bars rigidly in each connection, after the tool is removed.
- a further object of the invention is to provide a hook on the lower portion of the tool which may with a single movement of the hand while gripping the handle of the tool be hooked under the bars, and the bars lifted so that a tie provided with a long support may be slipped into the tool and a single stroke of the lever will close the tie and complete the connection. This is very advantageous for the reason that the bars usually rest on the bottom of the form and the tie in that case cannot be applied until the bars are lifted.
- a still further object of the invention is to provide adjustable means on the tool so that ties may be applied to the various sizes of bars with a single tool.

Specification of Letters Patent.
Patented Apr. 13, 1915..
Application filed June 26, 1913. Serial No. 775,894.
To all whom it may concern:
Be it known that I, JACOB B. NnnvnL, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Applying- Tools for Concrete-Reinforcing Ties, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to a tool for applying ties to concrete reinforcing bars and seeks to provide a simple and effective form of tool which may be applied to the tie and the reinforcing bars when and after the bars are set in forms, for closing the tie on the bars and binding them securely together.
In the casting of concrete walls, floors and the like, bars are placed in the forms before the concrete is poured, and spaced at intervals to reinforce the concrete, the bars usually crossing each other at approximately right angles, although sometimes they are secured in parallel connections, and ties are used to securely connect the bars where they cross or meet. It is essential that tools for applying ties to concrete reinforcing bars be provided with a hook to pick up the bars when they are lying on the bottom of the form so that the tie may be readily placed within the tool or in place on the bars, and that the tool be so constructed that a single movement will set the tie firmly on and around the bars so that they will be readily connected by the tie. Adjustable features whereby the tool may be readily changed to conform to the various sizes of ties and bars so that one tool will apply all ties on a structure, is also very desirable.
The present invention seeks to provide an improved tool which may be applied directly to the ties and the bars of concrete reinforcing for closing the ties on, and Se curely connecting the bars. Heretofore ties have been applied to the bars by hand and closed with a hammer or other like tool which consumes considerable time and does not produce the desired results, as with hammering and the like the ties cannot be closed with suificient snugness to grip the bars and hold them rigidly in place, but with a tool that is fitted around the bars and the tie, the tie may be closed with a single stroke of the lever of the tool and the ties are gripped on the bars with sufficient force to grip and hold the bars rigidly in each connection, after the tool is removed.
A further object of the invention is to provide a hook on the lower portion of the tool which may with a single movement of the hand while gripping the handle of the tool be hooked under the bars, and the bars lifted so that a tie provided with a long support may be slipped into the tool and a single stroke of the lever will close the tie and complete the connection. This is very advantageous for the reason that the bars usually rest on the bottom of the form and the tie in that case cannot be applied until the bars are lifted.
A still further object of the invention is to provide adjustable means on the tool so that ties may be applied to the various sizes of bars with a single tool.
The tie illustrated in the drawings is in commercial use and is the subject matter of my pending application for Letters Patent filed May 26, 1913, Serial Number 769,878, the same having been filed as an improvement on my Patent No. 1,068,003, granted July 22, 1913, it is not desired however to restrict the use of the tool to the exact form of tie illustrated or to those of the applications mentioned as other forms of ties may be advantageously applied to reinforcing bars with the improved tool.
With these and other objects in view the invention consists in the features of construction combinations and arrangements of parts illustrated in the accompanying drawings and more particularly pointed out in the claims appended.
Figure 1 is a view in elevation of the improved tool. Fig. 2 is a view in elevation of the tool at a different angle to that of Fig. 1 and with the handle broken away to save room in illustrating. Fig. 3 is a view in vertical section of the tool taken on line aa of Fig. 2 looking in the direction of arrow 1. Fig. 4 is an inverted plan view of the lower part of the tool with certain parts removed that would show in the back ground. Fig. 5 is an enlarged view in elevation of the tool applied to a tie and a pair of bars that cross in transverse directions, the end of a bar being dotted in the view to illustrate the relations of bars conheated in parallel, and the handle being broken off to save room. Fig. 6 is an enlarged fragmental View of the same application of the tool as that shown in Fig. 5, but at a different angle.
7 The body 1 is preferably rectangular, the upperportion being channeled and comprising flanges 2 and 3, and web hthe web 4 and flange 2 beingcut away at the lower portion and the flange 3 enlarged to add strength. On the lower end of flange 3 preferably integral therewith is formed the foot 5 the upperside standing at a right angle. to the body 1 excepting the depression 6 which is concaved from the upper surface to accommodate a bib or the like that may be on the bar at this point when the tool is applied to the bars, and the point 7 which is pointed and turned upward to assist in pickingup the bars when they lie on the bottom of the form. ,The foot 5 is providedwith slot 8 to receive the body 1 of the tie, the purpose of the slot and the operation :of the foot will more clearly appear hereinafter. V
J aw 9 is slidably attached to the body l and preferably has a flat bearing against the edges of flanges 2 and '3, with a yoke 10 fittingaround the body and holding the jaw inrelative relation thereto. The body 1 and jaw 9 end upward in the form of bifurcated jaws in which are pins 11 and 12 respectively, the handle 13 being pivoted 1 onthe pin 11, and provided with cam slot let whose sweep is solocated and arranged in the handle as to hold jaw 9 through pin 12in the extreme upward position when 'plied.'t o handle 13 throughout the entire travel of the jaw, also after jaw 9 has approached thefoot 5, it may again be lifted "'to theposition shown in Fig. 1, by raising thehandle13. It is obvious that jaw 9 will travel to and fr'o along the body 1 as handle 13 1S; oscillated on pin 11 and that a consider'able force may be exerted on the jaw by thehandle'.
E tendin through jaw 9 and into the space between flanges 2 and 3 at an acute angle to theupper face of foot 5 are guides 15 and 16, and screw 17, the guides being extensions ,ofthe' jaw 18, and the screw be.- ing threaded into jaw 9 and provided with the roundflat headi19, which vbears against thejaw, and is knurled so that it may be {easily turned to and fro, and is prevented 'Yfrom' moving away from the jaw 18 by bracket 20, which is secured to the jaw by screws 21. The distance of jaw 18 from jaw 9 is regulated by screw 17 and is varied to accommodate the size of the bars to which the tie is to be applied, the tool as illustrated in Fig. 1 being adjusted to apply a tie to a small pair of bars, while in Fig. 5 the tool is in position at the completion of the application of a tie to a larger pair of bars. The jaw 18 is moved to and from the jaw 9 in a line which is an acute angle to the upper face of foot 5, as the screw 17 is turned to and fro, so that the corner 22 of jawv 18 will reach approxima tely a level with the center of bar 2, with the tool in an uprightposition, when the top of the corner 23 of j aw 9 strikes the bar 3, which prevents further movement of the jaws or handle, and owing to the angle of the adjustment of jaw 18 the same result is accomplished on the various sizes of bars.
To operate the tool it is preferably carried in one hand by the handle 13, and the point 7is inserted under the lower bar 3 at the point where a connection is to be secured, the bars usually lying on the bottom of the form, and without shifting the hold on the handle the bars are raised with the tool to the required height, when the bodyportion 1 of the tie is inserted in the slot 8 withthe other hand of they workman, which is immediately followed byja lowering of the tool and a down stroke of the handle 13, resulting in foot 1 of the tie resting on the bottom of the form, the bar 3 resting on arm 5, the bar 2 resting on bar 3 and the arms 6 being set in the position shown in Fig. 6, securely binding and connecting the bars. v.
Before and at the movement of inserting the tie in the tool the arms 6 are as indicated in dotted lines of Fig. 5, and point 2 1 of jaw 18contacts with the arms of the tie first as indicated in dotted lines in Fig. 5 but as the handle 13 is lowered the bearing of jaw 18 on arms 6 is transferred from point 24 to corner 22 which provides the final set and grip, drawing and pressing the arms tight to the bars.
It it obvious that when the bars are a suiticient height from the bottom of the form the tie vmay ,beinserted-in the slot 8 of the tool before it is applied to the bars, and in this case a single stroke of the hand which grips the handle 13 will apply and set the tie on the bars. It will be noticed that the handle 13 is pivoted to swing in a transverse direction from the body 1, to that of the projection of point 7, and this is of advantage in placing the point under the bars, as it provides a stiffness to the tool in the direction of inserting the point under the bars. The lower end of jaw 18, is constructed so that point 24 will contact with arms 6 at some distance from the bars for the reason that the arms bend more easily thereby and retain a straight direction from the curved portion to the extreme end.
It will be understood from the foregoing that the workman may walk along a line of connections with the handle 13 of the tool in one hand, and almost without breaking step insert point 7 under the bars, lift them, insert the tie in slot 8 and with a downward pressure on the handle complete and secure the connection, and that if the bars are far enough from the bottom of the form the tie may be inserted in the slot 8 while stepping from one connection to another and with a single stroke the tie may be applied and the connection secured.
It is obvious that numerous changes may be made in the details as set forth without departure from the essential of the invention.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In a tool for applying ties to concrete reinforcing bars, the combination of a body portion, a foot projecting laterally from said body portion, a jaw slidably attached to said body portion, a second jaw whose distance from said first jaw and said foot is adjustable, and a handle by which said jaws may be pressed toward said foot and withdrawn.
2. In a tool for applying ties to concrete reinforcing bars, the combination of a body portion, a foot projecting laterally from said body portion, said foot provided with a second projecting point, a jaw slidably attached to said first jaw and said foot portion, a jaw whose distance from said body is adjustable, and a handle by which said jaws may be pressed toward said foot and withdrawn.
3. In a tool for applying ties to concrete reinforcing, the combination of a body portion, one end of said body portion provided with a foot projecting laterally therefrom,
a handle pivoted to the opposite end of said body portion, a jaw adjacent said body portion and slidably connected thereto, a jaw adjacent said slidably connected jaw Whose distance from said body is adjustable, said slidably connected jaw provided with a pin, and a cam slot in said handle connecting with said pin whereby the oscillation of said handle may press said jaws toward said foot and Withdraw them.
4. In a tool for applying ties to concrete reinforcing, the combination of a body portion, one end of which is a bifurcated jaw, a pin in said jaw, a handle pivoted on said pin, the opposite end of said body portion provided with a foot, a jaw adjacent said body portion and slidably connected thereto, a jaw adjacent said slidably connected jaw whose distance from said body portion is adjustable, one end of said adjustable jaw provided with a bifurcated jaw, a pin in said bifurcated jaw, and a cam slot in said handle connecting with said pin whereby the oscillation of said handle may press said jaws toward said foot and withdraw them.
5. In a tool for applying ties to concrete reinforcing, the combination of a body portion with a foot, a jaw slidably connected to said body portion, a handle constructed and arranged to slide said aw to and fro along said body portion, and an angularly adjustable jaw whose distance from said body portion is adjustable, the adjustable angle of said angularly adjustable jaw being acute to the face of said foot and so arranged that the applying corner of said jaw will approximately span one half of the diameter of the bar nearest to said handle.
In testimony whereof I afiix my signature in the presence of two witnesses.
