TANK-LUG.

SPECIFICATION forming part of Letters Patent No. 744,794, dated November 24,1903.

Application at May 22, 1902.

To a, w/tom it may concern:

Be it known that I, GEORGE P. RASCK, a citizen of the United States, residing in Des Moines, county of'Polk, State'of Iowa, have invented certain new and useful Improvements in Tank-Lugs, of Whichthe following is a specification.

My invention relates to band fasteners, and more particularly to that general class of fasteners which are especially adapted for use upon tanks and similar articles; and it has for its object to improve and simplify the construction of such devices; and to this end it consists in a fastener embodying the features and arrangement of parts substantially as hereinafter more particularly set forth.

Referring to the accompanying drawings, Figure 1 is a plan view showing the fastener in position. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a section on the line 3 3,

Fig. 1, looking in the direction of the arrow;

and Fig. 4 is a similar section of a modified form of fastener.

My present invention is an improvement on that shown in Patent No. 696,592, granted to me April 1, 1902, and embodies many features shown therein,said features being modified and adapted for use in connection with certain new features, as hereinafter more particularly pointed out.

Referring to the drawings, A represents a portion of a tank made up in the present instance of wooden staves a ct a and B B represent the ends of a band of metal or similar material passing around the tank, to which the fasteners or lugs are attached and by means of which the band is'tightened. Each of the'lugs O is preferably a complement of the other, and they can be used interchangeably. Each lug, preferably formed of metal, as phosphor bronze or similarmaterial, is provided with what may be termed a base portion 1, which in the present instanceis cut away, leaving an opening 20, and this base portion is preferably thickened toward its center, as indicated at 21. Rising from this base portion are the upright sides 2,and extending from these over the outer portions of the base is the inclined top portion 3, and extending longitudinally through the center of the top portion is a cylindrical portion 4, havlug an opening 5 for the reception of a suitthe end of the band.

Serial No. 108.555. (No model.)

able connector, (shown in the form of a bolt or rod E, having at one or both ends a nut E.) This opening is preferably cylindrical at its outer ends, and there is a cross-piece 6 be,- neath the opening, which is arranged above the base portion 1, so as'to form a longitudinal fiat slot or passage 7 for the reception of The sides of the arched portion 4 extend downward, as at 8, into the 'plane of this slot and form rectangular channels on each side of the cylindrical opening, the walls of the channels being formed by the base portion 1, the inclined topportion 3, the upright sides 2, and downwardly-extending sides 8. The inclined top portion 3 extends only partially over the base portion 1 and the upright sides 2, beyond the inclined top porledges 9, and the ends of these ledges adjacent the top portion are preferably beveled at 10. Arranged in the channels are looking devices D, shown in the form of rectangular wedges, having a plain flat bearing-surface 11 adapted to slide in contact with the inner surface of the inclined top portion 3, and the opposite side of the wedge is preferably provided with teeth or projections] 2 toengagethe band B. The outer portion of the rectangular wedge is cut away or reduced, as at '13, and there is a retaining device for holding the locking device in the rectangular channel (shownin the form of a toe or projection 14) arranged on the inclined top portion 3 and adjacent the reduced portion of the-wedge, so as to engage the abutment 15 and prevent the wedge slipping out of the channel. The wedge is preferably of greater length than the channel, so that when in operative position it will project at each end beyond the ends of the channel. in which it is supported and be in position to be struck by a hammer or similar tool on either end to tighten or .loosen its engagement with the band.

In Fig. 4 I haveshown a fastener embodying the general features of constructionabove described, but made double, so as to permit the use of two bolts or rods E, and similar parts are marked the same as in the other figures, and no detailed description is necessary.

It will be seen that each lug has an arched portion for the reception of the bolt, and on tion, are provided with inwardlyprojecting ICO each side thereof there is a rectangular channel for the locking devices, which are generally rectangular in shape and have a Wedgelike clamping action to hold the end of the band in place, and when the end is inserted in the opening 5 the locking devices readily yield, but are held from displacement in their channels and then may be secured by a blow or tap, and when once in locking position the the strain of the bands tends to cause the locking devices to more tightly engage the bands.

That I claim is- 1. In a band-fastener, a lug having a slot for the reception of the end of the band, an opening for the reception of a bolt, channels one on either side of said opening, and a Wedge-shape locking device in each channel, and of greater length than the channel, substantially as described.

2. In a band-fastener, a lug having a slot for the reception of the end of the band, a centrally-arranged opening for the reception of a bolt, channels one 011 each side of said opening, a toe controlling the channels, and a rectangular locking device in each channel having an abutmentto cooperate with the toe, substantially as described.

3. In a band-fastener, a lug having a slot for the reception of the end of the band, a plurality of rectangular channels, and locking devices in said channels arranged to engage the end of the band, and of greater length than said channels, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

GEORGE P. RASCK.
