BRAIDING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 521,019, dated June 5, 1894. 7

Application filed October 18, 1893. Serial No. 488,552. (No model.)

To all whom it may concern.-

Be it known that I, JAKOB DRNEK, a subject of the Emperor of Austria-Hungary, residing at Vienna, Austria-Hungary, have invented a new and useful Braiding-Machine, of which the following is a specification.

This invention relates to anew and useful improvement in braiding machines, and it consists in the'arrangement and combination of parts hereinafter set forth and claimed, whereby the spindle carrying the bobbin or spool is carried positively bya rotating plate instead of as heretofore traveling in a circular track.

The invention is illustrated in the accompanying drawings, wherein-- Figure 1 is a longitudinal section of the machine taken on the line w-w, Fig. 5. Fig.

,2 is a transverse section of the machine taken on the line y-y Fig. 5. Fig. 3 is aplan view of the machine sectioned on the line zz Fig. 1. Fig. 3 is a transverse section taken on the line y-y Fig. Fig. 4 is a plan view of the machine sectioned on the line 12-11 Fig. 1. Fig. 5 is a top plan view of the entire machine. Fig. 6 is an underneath view of the ribbon holder or spindle. Fig. 6 is a top plan view. Fig. 6 isa side elevation and Fig. 6 an end view of saidbobbin holder.

Fig. 7 is a side elevation of the machine and.

of one form of braid woven thereby and Fig. 8 is a diagrammatic view of the course taken by the bobbins during the operation of weaving in a machine of the form illustrated.

Upon a suitable bed plate 1 is secured the casing 2 the inner wall or periphery2 of the 1 same being substantially 8 or incising circular shaped. Within the center of each half of this casing 2 are placed two shafts 7-7-, one of which 7 is a continuation of the power shaft 4.. The power shaft has a bearing in the bed plate 1 (being supported by the collars 3, 3) while the shaft 7 is firmly secured to and supported on the bed plate 1 by means of the collar 3 and nut 3 Firmly secured to the shaft 7 is ,a gear wheel and plate 9, secured together by a sleeve 8. One form of securing the gear 5 and plate 2 to the shaft is shown in Fig. 1 wherein the same is ac complished by means of a set screw 8* passing through the sleeve 8. The gear wheel 5 meshes with a corresponding gear wheel 6 of exact diameter and of the same number of I shafts 7 and 7 are substantially conical by preference and the plate and gear wheel on each shaft is held down in place between the collars 11 and 3. The peripheries of the plates 9 are beveled in opposite directions as at 9 so that they overlap directly in the center of the machine (see Figs. 1 and 3). At certain regular predetermined points in the circumference of eachplate 9 are cut semicircular slots or recesses 10 shown in the drawings to be three in number in each plate. These slots 10 are approximately the same in width as the diameter of the shaft 12 of the bobbin holderD. This shaft 12 is clamped in the slot 10 by the square collars or plates" 13 which fit on the upper and lower surfaces of the plate 9. Two of the sides 13 of the collars 13 are rounded on anarc of a circle corresponding to the circular wall 2 of casing 2. The recesses 10 are cut to such a depth and the distances between the curved sides of plate 13 are such that when the shaft 12 of bobbin holder D is in said recess, one of the curved sides 13 of said plates 13 will slide over the curved wall 2, which wall 2 acts as a bearing therefor. The lower of the two sleeves 13 carries on its under surface a rail 17 extending across the sleeve 13 from one flat side to the other and directly in the center of saidsleeve (see Figs. 6 and 6). Between the plates 9 and the gear wheels 5, 6 and at equal distances from each of the sleeves 8 is placed a plate 15 substantially as shown in Fig. 2 andhaving formed in its 11pper surface two diagonal grooves 16 crossing each other at the center of the machine and adapted to receive and guide the rail 17 of the bobbin holder. The upper end of the holder D is furnished with a shaft 14 (conical by preference) upon which the spool or bobbin Sp is placed.

In operation power is transmitted from shaft 1 to the shaft 7 which rotates the plate 9 and the gear wheel 5. This gear wheel 5 rotates the gear 6 and the other plate 9, both plates 9 and gears 5, and 6 traveling with the same degree of speed. The bobbin holderD too is carried by the recess of one plate 9 around one end of the circular wall 2 until the rail 17 reaches the groove 16 in plate when the bobbin holder is shifted over into engagement with one of the recesses 10 of the other plate 9 when that plate carries the bobbin holder around the other end ofthe circular wall 2 until the rail 17 reaches the end of the other groove 16 in plate 15, when the bobbin is again shifted into engagement with the first plate 9 and the operation continued indefinitely. The path of the bobbin is indicated in diagram in Fig. 8. The course of the other bobbins or spools is precisely similar to that above described. Where the plates 9 are furnished with three engagement points or recesses 10, there may be three bobbins used, which are arranged in such a manner, that they occupy-at certain intervals durmg the operation--the position shown in Fig. 5. By this arrangement collision between the bobbins is avoided, for in no case can they come in contact with each other at the plate 15, the only point at which they cross. It is manifest that more than three bobbins may be operated and that more than two plates 9 and gears may be used and that these plates 9 may have more or less than three engagement points or recesses 10. The arrangementin the cases supposed above depends simply on mechanical calculation and can readily be worked out by the skilled mechauic.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The combination in a braiding machine, of

the revolving shaft 7, a gear wheel 5, beveled plate 9, and sleeve 8 secured to said shaft and connecting said gear wheel and beveled plate together, said beveled plate being recessed at regular intervals in its periphery, a stationary shaft 7, a gear 6 meshing with said gear 5 and revolving on said shaft '7, a second plate 9 beveled in an opposite direction to the first plate and overlapping the same, a sleeve 8 uniting said second plate to said gear 6, a casing 2 surrounding said plates and substantially 8-shaped, with the stationary switch plate 15, provided with grooves 16 crossing each other midway between said shafts 7 and 7, said plate 15 being placed midway between the sleeves 8, and between the revolving plates and their gears, andwith a bobbin holder D carried by said revolving plates and held in the recesses thereof by the casing 2, plates 13 secured to said bobbin holder and adapted to rest on the upper and lower surfaces of said revolving plates, two of the sides of said plates being cut onan arc of the circle of the casing 2 and adapted to bear thereon until the bobbin holder reaches the plate 15, and with a rail 17, carried by the bobbin holder D andadapted to enter the grooves 16 of the plate 15 and to guide said bobbin holder thereon, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
