To all wtom it may concern:

Be it known that I, ETIENNE CHARLEs AMAND MlissoN, a citizen of the Republic of,

France, and residing in Lenclos, Department of LAube, France, have invented certain Improvements in Spinning-Mules, (forwhich I have obtained a French Patent No. 150,059, dated June 20, 1882;4 German Patent No. 21,165, dated July 23, 18825 Belgian Patent No. 59,412, dated October 30, 1882; British Patent No. 5,245, dated November 3, 1882 Spanish Patent No. 3,875, dated April 28,1883, and Italian Patent No. 14,802, dated November 15, 1882,) of which the following is a speciiication.

My invention consists in so constructing a spinning-mule that all the spindles on the carriage may be driven at the same speed.

In the accompanying drawings, Figure 1 is a view of a portion of one end of a mule embodying my improvements. Fig. 2 is a plan view of the same, but showing in addition the opposite end of the traveling carriage. Fig. 3 is a transverse section of the mule, showing the driving-pulleys in dotted lines. Fig. 4is a vertical section, drawn to a larger scale, of a portion of the rails and spindles of the mulecarriage. Fig. 5 is a sectional plan of the same. Figs. 6 and 7 are vertical sections of modifications.

A is the usual traveling carriage ofthe mule, with its spindles b mounted in step-bearings c in the lower rail, c', and in holsters cl in the upper rail, CV,- and B B are the standards of the fixed head-stock, provided with suitable bearings for the driving-shaft c2, with its fast and loose pulleys x a2. On each of the spindles b is mounted a pulley, b, with a cylindrical surface, and adjacent to each pair of pulleys, and between and partly behind the same, is a friction-pulley,f, mounted on a spindle, j", also having a step-bearing in the lower rail, c', and a top bearing in the bolster-rail d', Figs. 1 and 4. Between these friction-pulleys and the spindle-pulleys passes the endless driving belt or cord a, which passes around grooved guiding-pulleys h h, mounted on each end of the carriage. These pulleys f give the necessary tension to the cord and keep it in contact with the pulleys on the spindles b.

The driving of a number of spindles by one endless belt or cord has heretofore been practiced in xed spinning and throstle frames. In order to apply this method to the driving of mule-spindles, I employ the arrangement shown in Figs. 1, 2, and 3. The endless belt, after passing around the horizontal pulleys 7L h at the end adjacent to the head-stock, passes around grooved pulleys i j, mounted on fixed axes on opposite sides of the standards B B', a's indicated by dotted lines in Fig. 3, the pulleys z' j being at a suiiicient distance apart to allow the carriage its full movement without the guide-pulleys 7i h coming into contact with the said pulleys 13 j. The endless belt, after passing partially round the pulleys ij, passes around the grooved pulley a on the drivingshaft a2, which, through the means described, imparts the desired simultaneous movement to all the spindles. It will thus be seen that the length and tension of the endless cord a remain constant in every position of the mule carriage, and this without in the least interfering with the to-and-fro movement of the latter.

To prevent oil from running onto the surfaces of the pulleys Z from the bearings d d, an annular recess, e, is formed in the upper portion of each pulley to catch the oil that escapes i'rom the bolster d, and small vertical passages or channels e' are formed in the pulley to carry off the oil Aentering the recess e. Similar passages and recesses may be formed in the friction-pulleys f, as indicated in the modification Fig. 6. Y

If it is desired to reduce the length of the spindles f', they maybe mountedin a bracket or brackets, g, as shown in Fig. 6, in which case the bracket is adj ustably secured to a suitable part of the frame by screw-bolts or set-screws, as at g g. I prefer, however, to employ the adjusting devices shown in the modification Fig. 7 to secure the desired tension ofthe driving belt or cord. In this case each spindle f is mounted in an independent bracket, g, guided at top and bottom in slots L' in a frame or box, k, secured to the rails c d', or in slots in plates k2, secured to the said frame, as shown, at the lower end.

To the back of each bracket g is secured a 10o spring, fr, acted ou by au adjustng'screw, v, by which the tension of the spring, and consequently the pressure of the pulley f,0n the belt or cord can be easily regulated, and this regulation may be applied through any one or more of these friction-pul1eys- If desired, a hinged front board, D, may be applied to the rails c d in front of the spindles, as shown in Fig. 7.

I claim as my invention- The combination of the head-stock and traveling carriage cfa spinning-mule and spindles7V
