BAND-FASTENING.

SPECIFICATION forming part of Letters Patent No. 759,328, dated May 10, 1904,

Application filed March 7, 1904. Serial No. 196,993. (No model.)

To all whom it may concern:

Be it known that I, EMIL C. TEOKTONIUS, a citizen of the United States, residing at Racine, in the county of Racine and State o-fWis-' ing had to the accompanying drawings, forming a part thereof.

The improvement constituting my present invention relates more particularly to large fastenings for heavy flat bands. Its main objects are to prevent breaking the heads by tightening the wedges therein and at the same time securely fasten the bands in the head, so that they cannot slip, without riveting, accurately fitting, or exactly cutting to length.

It consists in certain novel features of construction and the peculiar arrangement of parts hereinafter particularly described, and defined in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a side view of a band-fastening embodying my invention, the member of the fastening to the left being shown in longitudinal section in a plane perpendicular to the band and the member to the right in elevation. Fig. 2 is aview of the fastening, partly in longitudinal section in a plane parallel with Fig. 3 is aview of the outer end of one of the heads as seen from the right with reference toFigs. 1 and 2, and Fig. 4 is a view like Fig. 1 of a modified form of the fastening.-

Referring to Figs. 1 to 3, inclusive, the fastening is composed generally of two heads a a, adj ustably connected by bolts 5 b. Each head is formed with a tapering longitudinal opening through it for the passage of one end of the band 0 and for the reception of a wedge (Z, fitted to clamp and secure the band therein. It is also formed on each side with a longitudinal sleeve for connecting it with the companion head by the tie bolts 7), which are threaded at the ends and provided with nuts f. An internal shoulder or abutment g is formed across the opening through each head on the jected.

outer wall of the head, and the wedge (Z is iitted in the head so that when brought into place snugly against the band it will abut at its smaller end against said shoulder, thereby preventing breaking or overstraining the head by forcing the wedge too tightly into it. The wedge is fitted so that it will grip the band with some force in the head before it is brought to a bearing against said shoulder. To insure against the band slipping in the head after the wedge is insertedin place, the end of the band is bent outward, as shown in Fig. 1, next to the larger end of the wedge, so that when strain is put upon the band by tightening the nuts on the bolts bthe heads cannot slip on the band without straightening the bends therein, and this with thick heavy bands can hardly occur with any strain to which they would ordinarily be sub- However, to insure against the bands being straightened and slipping in the heads screws it may be threaded in the larger ends of the heads in position to bear when adjusted against the inner face of the band, and thus retain the bends therein. To counteract the tendency of the endwise strain on theband to tip the heads inward at their larger ends, they may be formed, as shown, with lugs 71, adapted to bear upon the tie-bolts &.

In applying the fastening the band is cut to the required length, the ends are passed through the heads a from the smaller toward the larger ends of the openings, the wedges are then inserted and forced into place against the shoulders g, the ends of the band are bent outward next to the larger ends of the wedges, and if the screws it are employed they are inserted or turned up into place. The band is then ready for application to a tank or other structure, around which it is placed, the heads being then connected by the bolts 6 and drawn together, so as to put the desired strain on the band by turning up the nuts f.

Referring to the modification shown in Fig. 4, the heads a are formed with shoulders g on their inner instead of their outer walls, so that the ends of the band are clamped by the Wedges cl against the outer walls of the heads. In this case the ends of the band are bent inwardly over the larger ends of the wedges,

and the screws it are threaded in the outer walls of the heads in position to prevent the straightening of the bends.

The principle and operation of both forms of the fastening are essentially the same.

IVith my improved construction as embodied in either of the forms herein described the heads are held on the band and prevented from slipping thereon partly by the grip of the wedges and partly by the bends in the band at the larger ends of the wedges. Consequently the wedges do not have to be forced as tightly into the heads to securely fasten them on a band as they would if the grip of the wedges were alone depended upon for this purpose, and while they assist to hold the heads on the band and serve to distribute the strain on the fastening through the heads the shoulders g limit the extent to which the wedges can be forced into the heads and hence their tendency to split them.

Various changes in minor details of construction and arrangement of parts may be made without departing from the principle and intended scope of the invention.

I claim- 1. In a band-fastening the combination of a head having a tapering opening through it and an internal shoulder in the smaller end of said head, and awedge fitted to grip a band in said head and to abut at its smaller end against said shoulder, substantially as described.

2. In a band-fastening the combinationof a head having a tapering longitudinal opening through it and an internal shoulder across the smaller end of said opening, a wedge fitted in said opening to abut at its smaller end against said shoulder when forced into place against a band passing through the head, and one or more screws threaded in the larger end of the head in position to prevent the straightening of a band bent next to the larger end of the wedge, substantially as described.

3. In a band-fastening the combination of a head having a tapering longitudinal opening through it and an internal shoulder across its outer wall next to the smaller end of the opening and a wedge fitted to abut at the smaller end against said shoulder, when forced into place 011 a band passing through the head, substantially as described.

4. In a band-fastening the combination of a head having a tapering opening through it and an internal shoulder across the smaller end of said opening and a wedge fitted to abut at its smaller end against said shoulder when forced into place on a band in said head, the band being bent over the edge of the wedge at its larger end, substantially as described.

5. In a band fastening a pair of heads each having a tapering longitudinal opening through it and an internal shoulder across the smaller end, bolts adjustably connecting said heads and wedges fitted to abut at their smaller ends against the shoulders in said heads when forced into place on a band therein, substan tially as described.

6. In a band fastening a pair of heads each having a tapering longitudinal opening through it with an internal shoulder across the smaller end and longitudinal sleeves on the sides, tie-bolts secured in said sleeves by nuts and adjustably connecting said heads, and wedges fitted to abut at their smaller ends against the shoulders in said heads when forced into place on a band therein, substantially as described.

7. In ,a band fastening a pair of heads each having a tapering longitudinal opening through it and an internal transverse shoulder adjacent to the smaller end of the opening, wedges fitted to abut at their smaller ends against said shoulders when brought into place on a band in the heads, and means for adjustably connecting the heads and drawing the band taut around a tank or other structure, substantially as described.

In witness whereof I hereto affix my signature in presence of two witnesses.

EMIL O. TECKTONIUS.
