COTTON-BALE TIE.

SPECIFICATION forming part of Letters Patent No. 225,51*?, dated March 16, 1880.A

Application flied october 10,1879. 4

To all whom it may concern:

Beit known that I, SAMUEL H. GILMAN, of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and usei'ul Improvement in CottonBale Ties; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,

forming part of this specification, in which- Figure l is a top end View of the improved tie., Fig. 2 isanbottomjend view of the same. Fig. 3 is a vertical longitudinal section of the tie, the griping globes or balls being in their inactive position.' Fig. 4L is a vertical transverse section of the same, the globes or balls being partially in their active position; and Fig. 5 is a section similar to Fig. 4, the balls being in full action and occupying their eX- treme lower position. Fig. 6 is a diagram for 2o illustrating, in connection with the description hereinafter given, the operation of the tie.

My invention relates to the globe or ball tie for bale-bands patented by me June 18, 1878, No. 204,965 5 and the object of the improvement which I have now made is to provide against the slipping of the end of the band after the tie has been applied toit; also, to insure a bite of the globes or balls upon the band from the time they first touch the band untilv and 3o during the greatest strain upon the band.

In operating with the various descriptions of ties for cotton-bales during several years, I have discovered that the angle formed by the band with respect to the bearing-surface 3 5 for the` balls, and upon which the balls or globes should be applied to bite or gripe upon the band, cannot with any practical utility be less than six degrees nor morelthan ten degrees, and that the most successful angle upon 4o which the balls should be applied so as to gripe or bite upon the band with unerring certainty at all times is about seven and a half degrees.

The nature of my presentinvention consists in certain details of construction ot' the tie heretofore patented by me, whereby the balls or globes used for biting or griping upon the band are presented to the band on an angle ranging from six degrees to ten degrees, pret- 5o erably at an angle of seven and a half degrees,

and whereby the band is prevented from being deiected by the first contact of the balls therewith in such manner as to form an angle greater than ten or less than six degrees.

ln the accompanying drawings, A represents a metal tie of attened tubular form and tapering lengthwise. The tie is about one inch in length, and through it a broad oblong passage, a, is formed, said passage being equal in width to the cotton-bale band b b', which is 6o to be passed through it, as shown. Both faces of the metal forming the .broad sides of the l passage a are corrugated or channeled,l as shown at c and d, the channels cpbeing much deeper than those d, and are formed by ribs e e, which, in cross-section, are of wedge shape. These ribs are of nearly uniform depth from end to end of the tie, and between these ribs are semicircular channels or grooves o, corresponding in form, in transverse section, to the 7o surface of the balls B, which roll and travel in them during the operation of tying the bands upon the bale. The channels l are very shallow, and are formed upon the surface g of the tie, against which the end b of the band bears, and they are opposite the semicircular chau- .nels c, and permit the band to be depressed slightly within the tie when the strain of the band is acting upon the balls.

At the upper end of the tie, and on Vside g 8o where the deeper channels are formed, a guard lip or rib, f, is provided for the purpose of preventing the balls passing out of the tie at its upper end. The inner edge, f', of this rib f is on about the same vertical plane with the 8 5 lower terminus, e', of the ribs c.

The downward-extended inner bearing-surface, g, is inclined to a very considerable extent, while the other, g', is less inclined, and these surfaces, together with their guard f 9o and ribs e, are so arranged relatively to each other that an angle of about seven and a half degrees is formed for the bite ot' the balls between the outer surface, s, of the band d, Vthe ribs e, and the lower terminus, e', of the 95 ribs e, and consequently the balls or globes B bite the band on that angle lat the first impingement of the balls upon the band, and continue to bite (on a slightly-decreasing an gle) upon the band from the said first imroo pingement (shown in Fig. 4:) till the balls are fully seated, as signified in Fig. 5.

There of course Will be a slight change in the extent of the angle upon Whichthe balls bite or gripe, due to the compression of the 'metal of the bands and the depression of the sameinto the shallow corrugations d; but this is so slight that it Will not materially chan ge the angle or cause the balls to jam and Wedge so tight that the tie cannot be readily unlocked.

It Will be seen from the diagram shown in Fig. 6 that an inclination of seven and aA halfI degrees (represented by the lines g and s) causes the point of impingement t and u to stand very near the diameter D ofthe ball B, and thus a quick and sure bite between the two inclined sides is secured.

It Will also be seen that with a slight increase of the angle of the lines g s the points of impingement will be caused to stand so reA mote from the diameter D of the ball-as, for example, the points t @LL-as to render a biting impingement almost impossible with the same ball.

By providing for the biting of the balls upon an angle of from six to ten degrees, the ties can be made much shorter and the balls smaller, and, as two or more balls are employed in each tie, the bite Will be distributed over a cotton-bale band of ordinary commercial Width', and its hold will be much more effective and less destructive to the band than that of a single large ball and larger tie.

In some cases it may be desirable to adopt au angle of six degrees, or an angle ranging from six to ten'degrees; but my experience proves that seven and a half degrees is the most sure and proper one to adopt. I do not, therefore, limit myself to an angle of seven and a half degrees, but desire to employ an angle ranging from six to ten degrees.

/Vhat I claim isl. The'cotton-bale tie having its ribs e at their lower termini, e', of a depth about equal to the depth of the guard-ribf, and its broad sides g g, against which the band and balls bear, respectively, constructed and arranged in relation to one another substantially as and for the purpose set forth.

2. The cotton-bale tie provided with surfaces g g', guard-ribf, and ribs e, arranged to form an angle for the balls B to bite or gripe upon, of not less than six nor more than ten degrees, preferably seven and a half degrees, between the band and the ribs c, substantially as and for the purpose set forth.

Witness my hand in the matter of my application for a patent on a cotton-bale tie this 6th day of October, A. D. 1879.
