TIE LUGJ Application filed January 9, 1928. Serial No, 245,437.

This invention relates to tie lugs and is designed primarily for use in connection with concrete forms. I r

In assembling large concrete forms it'has 5 been the practice to connect opposed portions thereof by means of cross wires.

rious means have been employed for tightening these wires so as to hold opposed portions of the format proper distances apart but all of these means have been more or less complicated, and some of them'have required the workmen to operate inside of the space within the form which, usually, is impracticable because of the small size of the space and also because of thereinforcing metal located in the space.

It is an object of the present invention to provide simple and elfective tightening means located outsideof the. form where it can be actuated readily to take up slack in the tie wires and subsequently securely held. 7

Another object is to provide atie lug which is cheap to manufacture, easily han-,

dled and can not only be used to advantage in connecting the opposed side portions of a form, but can also be employed in supporting forms.

WVith the foregoing and other objects in 0 view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, with out departing from the spirit of theinvention. 7 V I In the accompanying drawing the preferred form of the invention has been shown. 7

The looped end'of the wire will seat in the depression 5 and within the opposed slots 6 in one of the'tie lugs while the terminal portions of the wire the lug is continued until the wire WV is twisted sufficiently totake up all slack therein after which the lugs are held against movement by driving nails retrograde through the slots 1 into the timbers B as shown at N. I i WVhat is claimed is:

1. A tie lug including a base, a centering boss extendlng from one face thereof, an

apertured wing extending diametrically across the opposite face thereof, there being opposed radial slotsin the base at opposite 7 sides of the'wing.

'2; tie lug includin posed slots extending therein fromits periphery, a centering bossextending from one face of'the base between the slots and a I diametrically disposed apertured wing on the other face of the base between the slots, said wing having a central depression constituting a seat ,for a twisted wire or the like.- 1

said wire being looped over the wing and having opposed portions seated in the slots,

"there being an aperture in the wing for the reception of a turning tool, and fastening meansextending through oneof theslots into the form member for holding the lug against rotation.

5. The combination with, a form member having an openingthereln, of a looped wire extending through the opening and constituting a tie, of a tie lug including a slotted base, an outstanding wing on one face of the base betweenthe slots straddled by the looped end of the tie Wire, said wing having a. depression constituting a seat for said looped end, a centering boss extending from the other face of the base and positioned Within the loop oft-he Wire, and fastening means engaging the'base and the form member for holding the base against rotation," 6. A tie lug including a base having slots extending thereinto from its head, a wing extending from one face of the base be tween the'slots for engagement by a turning tool, saidwing having a seat for a looped tie Wire extending through the slots, a, boss extending from the other face of the baseconstituting centering means.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
