To all whom it may concern:

Be it known that I, l/VILLIAM H. LA- rAnLLn, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Power-Shipping Mechanism, of which the following is a specification.

This invention relates to that class of power-shipping mechanisms to which the inventions described and illustrated in Letters Patent of the United States numbered 420,160, granted to me January 28, 1890, and Letters Patent of the United States numbered 891,267, granted to me June 23, 1908, belong; and it is intended to be an improvement over and upon the said inventions, and in inventions in which the power of a continuously-rotating shaft may be transmitted to either or both of two shafts which operate main shafts in transmitting motion to two diflere ntmachines, such as more particularly, but not necessarily eX- clusively, looms.

In my present improvement the principal objects are to provide greater efliciency in operation, to render the parts easily assembled and disassembled, and to enable the mechanism when a loom to which it is connected is being stopped (as when the filling breaks) to not only throw out the clutch on that side but operate a brake which accelerates the stopping of the shaft extending from the power-shipping mechanism to said loom.

The nature of the invention is fully described below, and illustrated in the acc0mpanying drawings, in which Figure 1 is a view of my improved mechanism, a portion being shown in plan and a portion in horizontal section, connected up to a pair of looms or similar mechanisms sufficient portions of which are shown to illustrate the operation of the invention. Fig. 2 is a view partly in elevation and partly in section taken on line 22, Fig. 1, looking toward the right. Fig. 3 is a front view taken at one end of the mechanism, a portion of the frame of the loom being shown in section. Fig. 4- is a section taken on line 4-4, Fig. 1, looking toward the left. Fig. 5 is a sectional detail of a portion of the brake and adjacent parts.

Similar nume als of reference indicate corresponding parts.

Referenceaiumeral represents the central drivingpulley connected with the power, 11 representing the web and 12 the hub thereof rigid on the central shaft 13.

1 1 and 15 (Figs. 1 and 2) represent a pair of flanges integral with the web, extendin on opposite sides thereof, and concentric with the periphery of the pulley-said flanges being exactly alike.

In line with the drivingshaft or pulleyshaft 13 and extending from opposite ends thereof are the two main shafts 16 and 17 which are adapted to extend into two separate machines, such as looms, and operate as driving-shafts for the same. Surrounding the shaft 13 next the hub 12 are the collars 18 and 19. Each of these collars is made in two parts, as indicated by the dividing line 21 shown dotted in Fig. 2 and in a full line in Fig. 1, and integral with one part of the collar (the lower part as illustrated in Fig. 1) is the sleeve 20, below described. As will readily be understood, in Fig. 1 the outer surface of one-half of the divided collar on the right side of the pulley-wheel is shown and tne inner face of the opposite half of the divided collar on the left side of the pulley-wheel, the sleeve being in section. Integral with the two parts of each of the divided collars are two parallel bars 22 secured ogether by abolt and on the opposite side of each collar there are integral with its two parts a short ear 2st and a curved arm 25, secured together by a suitable bolt 26. Hence one part of each divided collar is integral with the sleeve one bar 22 and the arm 25, while integral with the other part of the collar is one bar and the short car 24-. These parts 22, 23, 21-. and 25 on opposite sides of the pulleywheel are exactly alike, and the same is true of all the parts described below located on opposite sides of the pulley-wheel, and hence the same reference-1mmerals will be used for describing the parts on both sides of the web 11 of the driving-pulley.

Pivotally secured at 27 to the outer end of each of the arms 25 are the adjacent ends of a pair of curved yokes or clutch-members 28, the yokes of each pair, that is, the yokes on each side of the web 11 being pivoted together as well as to the arm 25 at 27 and extending along the outer surface of the flange 1st (or 15 as the case may be) until their opposite ends are adjacent to each other. These ends, that is, the ends of the yokes which are opposite the pivots 27 are Cir provided with integral ears 29 formed nonradially with the yokes whereby they extend outward and apart from each other at their outer ends, as clearly shown in Fig. 2. A spring 30 between said ears holds them normally sufliciently apart from each other to keep the yokes or clutch-members 28 off the surface of the flange lat (or 15).

Clutch-levers 31 are pivotally connected at 32 to and between the bars 22, the short arm of each of said clutch-levers being provided with a frame which consists of the bar 33 at right angles with the clutch-lever and the two parallel jaws 34; set at right angles with the part 33, but with their inner surfaces spreading apart at their outer edges at substantially corresponding angles with the ears 29 (Figs. 1 and 2) whereby they are enabled to bear against the outer surfaces of the opposite cars 29. The long arm of each of these levers 31 is provided on its outer surface with a bunch or protuberance 35 near its outer end, and said outer end extends into a recess 36 in the sliding sleeve 37 which consists of two parts bolted together at 38 and is slidingly mounted on the sleeve 20 on that side. it regulatingscrew 39 bears against the surface of the outer end of the long arm of each lever 31. The sleeves 20 are rigid on the shafts 16 and 17 by means of keys s0, and each sleeve 1 20 is provided with an annular ring or flange 1-1 next the boss or enlar ed portion t2 of the shafts 16 and 17, and an extension or flange 13 integral with the sleeve 20 sur rounds said boss. Integral with the sleeve 37 and between it and the shoulder ll is a shipping-pulley 1% made in two parts to correspond with the sleeve 37, and mounted.

on the portion 43 of the sleeve 20 is a large brake-wheel 1-5, said brake-wheel being rigid on the sleeve by means of suitable screws 57, (Fig. 1), and the sleeve being, as above mentioned, rigid on the shaft 16. Preferably I provide adjusting-screws 16 for the jaws 3 1 whereby said adjusting-screws can, if desired, bear against the adjacent surfaces of the cars 29.

4C7 represents portions of frames of ordinary looms into which the opposite shafts 1G and 17 extend and constitute drivingshafts, said looms being provided with the ordinary loom shipping-levers 13' and rockshafts 19 operating in the wellknown manner in case of the breaking of the filling to stop the machine.

represents a clutch shipping-lever connecting at its outer end with the loom shipping-lever 4:8 and provided at its inner end with a yoke 51 whose ends extend into the groove in the pulley at. Rigid on the rockshaft 49 is an arm 52 whose outer end 53 is 'in engagement with the loom shippinglever 18, and also rigid on the rock-shaft is a curved brake-lever 5% on whose outer end is the curved brake or shoe 55 which is adapted to be applied to the b 'ake-wheel 45; it being understood that the looms on both sides of the mechanism are provided wit-h similar brake-mechanisms for application to the two brake-wheels 4E5.

111 the drawings the power-shipping mechanism is represented as being stationary with the exception of course of the driving-pulley which is always running. The brakes 55 have been applied by the loom shippinglever &8 to the brake-wheels, the pulleys eta are held back against the flanges 41 by the yokes 51 on the clutch shipping-levers 50, and hence the sleeves 37 are moved back far enough to allow the bunches 35 to be withdrawn from under the regulatingscrews 39, thus allowing the aws 3st on the short arms of the clutch-levers 31 to be moved down by the ears 29 integral with the clutch-members 28, said ears being forced apart by the springs 30, and hence the clutch-members being spread out of contact with the flanges 14: and 15. If the loom on the right side, for example, of the power-shipping mechanism is to be started, the loom shipping-lever %S is swung from the position illustrated in the drawings into the notch 56 (Fig. 1), swinging with it by means of the rock-shaft a9, the brake- mechanism 52, 53, 55 and thus releasing the brake-wheel At the same time the clutch shipping-lever 50, which is in engagement with the loom shipping-lever 18, is moved inward thereby, its yoke 51 sliding the pulley 14: and with it the sleeve 37 toward the driving-pulley, and hence moving said sleeve with its regulatingscrew 39 along the long arm of the clutch-lever 31 and upon the bunch 35, pressing down the outer end of said long arm and forcing up the short arm of the clutch-lever and hence swinging up the beveled jaws 34: whose inner surfaces bear against the outer surfaces of the spreading ears 29, forcing said ears toward each other against the power of the spring 30, and moving the curved yoke or clutchmember 28 against the outer surface of the flange 15. This causes the driving-pulley 10 to communicate rotation to the clutch-member and thence to the clutch-lever 31 and by means of its connection at 32 to the bars 22 and by means of the connection at 27 to the arm 25, and as one of the bars 22 and the arm 25 are integral with one-half of the divided collar 18 rotation is imparted to said collar. The rotation of the collar is communicated to the sleeve 20 integral with said half as above described, and said sleeve communicates rotation to the shaft 16 by means of the key at), driving the loom with which it is connected. Moreover the sleeve communicates rotation to the brake-wheel 15 which is rigid thereon by means of screws 57 or in any other suitable manner.

CIT

@f course either or both of the shafts 16 and 17 may be set in operation by the clutches and thus actuate one or both of the looms on either or both sides of the mech anism.

By means of the divided collars 18 and 19, the parallel bars 22 integral with the two parts of the collars, the parts :24- and 25 in tegral with the two parts of the collars, the

sleeves 2O integral with one part of each col lar, and the divided sleeves 36 and divided pulleys 14, it is easy to disassemble the parts y withdrawing the bolts 23, 26, 32, and 88, and to reassemble them by applying said bolts.

By the operation of the brake which is set against the brake-wheel d simultaneously with the movement of the rock-shaft 4-9 of the loom, whether said loom is stopped automatically or by hand, the stopping of the loom is accelerated by the operation of the brake-wheel on the shaft 16 or 17 as the case may be. Such action stops quickly the rotation of the sleeve and shaft 16 and hence the rotation of the collar 18, and the clutch sl1ippinglever which is operated by the loom shipping-lever at the same time by reason of the connection of said. loom shipping-lever with the rock-shaft 4L9 withdraws the sleeve 37 and allows the jaws 3a of the clutch-lever 31 to release the spreading cars 29 and hence allow the clutch-member 28 to be spread by the spring out of contact with the flange 15 on the driving-pulley.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
