4 Claims. -(l. 254 181.
This invention relatesto a tie puller for pulling form ties or tie rods from concrete after the concrete has set.
In the so-called architectural type of concrete work tie rods of small diameter are utilized and are pulled out after the concrete has set, thus leaving relatively small holes to be patched 0r. filled in. The concrete having set tightly grips the tie and considerable efiiort and force are required to loosen and withdraw the tie rod.
This invention has for its salient object to provide a concrete tie puller that is simple in construction, efiective in operation and can be economically manufactured;
Another object of the invention is to provide a device of the. character described that can be used to loosen as well as to pull .tie rods.
Further objects of the invention will appear Patented Sept. 7, 1943 r from the following specification taken in connection with the drawing which forms a part of this ing the tie puller;
Fig. 3 is a transverse sectional elevation taken substantially on line 3-3 of Fig. 2; and
Fig. 4 is an elevational view showing the tie puller in operation pulling the tie.
In the particular embodiment of the invention shown there are illustrated form boards l0 and H which'are held in place by a tie rod l2, it being understood that a plurality of tie rods is used.
The tie rods may be of any desired construction and as shown each tie rod'h-as a pair of heads at each end, the heads being indicated at I 3 and M. The rods extend through openings [3 and Win the form boards [0 and H and between spaced vertical beams or studs Hand l8 and spaced horizontal beams or walers I9 and 20.
The ties are held in position by'spreaders or clips 25 which are secured over the rods adjacent the collars l3 and by wedges 26 which are driven over the outer end portions of the rods adjacent the outer heads or collars [4. The constructions Samar, QfTntPUL-nnit I 1 v o Selle N. J1, assignon byg M v es i mlsnie to Re1 h-E:- dg .;=N w,.
The invention claimed in this application con sists'of means for loosening and pulling form ties after the tie holding means have been removed and the concrete has set. This means consists of a pulling member comprising an elongated rod or shank 33 having secured to one end a foot or shoe 3| consisting of a bar secured to and extending transversely of the end of the rod or shank 30. This bar has preferably formed thereon a pair of barbs or spikes 32,
The rod 30 has slidably mounted thereon a head 33 which fits loosely on the rod or shank of the sheathing on the left side of Fig. 4 and the puller is shown engaging the outer head M on the right hand side of the figure. .The slidhead away from the foot bar until the tie is fully loosened in the concrete.
The sliding head is y then moved back into contact with the foot bar and. the withdrawal completed by the jarring action of the handle 36. This jarring action may be used in unison with the lever action in the position shown in Fig. 4 to start the tie.
It will be evident that the head 33 can be moved successively outwardly on the rod 30 and of the clips 25 is not material to the present in- Furthermore, it should be understood that the particular construction of form tie and of the holding means therefor has nothing to do with the present invention.
:when the rod is moved in a direction to cause the and 2!] and prevent the tool from slipping,
Although one specific embodiment of the invention has been particularly shown and described, it should be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the cooperating parts may be made without departing from the spirit or scope of the invention as expressed in the following claims.
I claim:
1. A tie rod loosener and'puller comprising a shank, a shoe on one end of the shank, a head slidably and tiltablymounted on the shank and having 1a =--c1aw:1 extending transversely; of. the shank, a handle slidablymounted 0nthe shank 10' and a head on the other end of the shank. h
2. A tie rod puller comprising a shank, a shoe on one end thereof, and a head sli-dably mounted on the shank and having a loose fit thereon whereby a limited tilting movement oitiienead it is permitted to lock the headin--position onsaid head having a fork at one end there- Jthetie rod-p on one end thereof, a head slidably mounted on mitted to lock the head in position on said shank,
said head having a. fork at one end thereof, an
abutment on the shank and a handle slidably mounted on the shank between the head and the abutment. v
