To all whom it may concern:

Beit known that I, WILLIAM H. LAFAELLE, a citizen of the United States, residing in Boston, i'n the county ofSuifolk and'State of Massachusetts,have invented new and use. ful Improvements in Power-Shipping Meehanism, of which the following ,isa specificaescribed and illustrated in Lety 420,160, granted to me January 28, 1890, be-

` longs; and it is intended' to be an improvement over and upon the said invention, and

in inventions inwhich the power of a continuously-rotating shaft vmay be transmitted to either or both of two shafts which operate as main shafts in transmitting motion to two l different machines, such as looms, for eX- am le, n

n my improvement the principal objects are to provide greater simplicity, to lessen the liability of any of the shafts becoming bent or-twisted and thus gettingout of line, to provide a better balance of the main shafts, and to provide an improved mechanism, whereby the clutches are directly connected Withthe driving-pulley by means of friction-yokes which are located within the general' limits of the pulley on op osite sides of the web thereof and are direct y operated by a double flange ora pair ofoppositely extendin 'flanges integral with `said web and locatec between thc periphery and tlie hub of the pulley, thereby rendering the mechanism exceedingly compact and rigid.

The nature-0f the invention is fully des cribed below, and illustrated in the acconipanyingdrawings, in whichz- Figure 1 is an elevation orside view of my improved mechanism.

Fig. 2 is a central longitudinal section of the same. Fig. 3 is a vertical section taken on Vline 3--3,'Fig. 2, looking toward the right.

Similar numerals of reference indicate corresponding parts.` l

Reference numeral 10 represents the `driving-pulley which is connected with the power, ,11 being the web thereof and 12 the hub rigid on the central shaft 13..

Same.

ears 30 an( 16 and 17 are main shafts which may eX- tend in'to two separate machines, such as looms, and operate as driving-shafts for the' oppositeends thereof, and rigidon the shafts V16 and 17 are collars 18 and I9 respectivelyQ The collar 18 is provided with two pairs of integral ears 20 on which are' ends are pivotally connected at 23 Withe'ars 24 integral with the two yokes 25 which are concentric with the flange 14. Theouterends of the clutch-levers 22 are provided with ad- 70 justable screws 26 which bear onA the periphery of a cene 27 'adapted to slide on ,the shaft 16 and providedv with an yannular groove 28 by means of which the cone is engaged by a shipping-lever ,fO'n the oppositeI sideof the web 11 ofthe" drivingepulley are two Apairs of ears integral lwith the collar' 19,

and clutchdevers /31 pivoted at 32 to said l i/v/ ytallyconnected at ears 34 on y' Y l provided wil djiistableliserewslbeang on a conej'( groovedat 38ffto "receive a shipping-lever Sfthe mechanism on both sides' ofthe pulley being exactly alike.

In the drawings theyokes 25 on the left of 85 the'web 11 of the pulley are represented as in engagement with the concentric flange 14 on that side, said yokes having been placed in engagement by the shipper 29 which has moved the cone 27 inward or toward the pul-x 90' ley, thus lifting the outer ends of the clutchmechanisms 22 by forcing thehigher portion of the cone under the screws 26. The yokes 35 however on the right hand side of the web are out of engagement with the flanges 15 on 95 the same. side, as the shipping-lever 39 is holding the cone 37 outward, or toward the right, allowing the outer ends of the clutch-v v levers 31 to drop with their screws 36 onto the lowestjportion ofthe periph-'ery of the 100 cone 37 The d iving-pulley therefore which beingfast on the shaft v13 is rotating said shaft constantly, engages by means 'of its flange 14 the clutch-mechanisms on the left side, imparting rotation thereto, and byI 105.4

means of the ears 20 imparts rotation to the collar 18 which incl'oses the adjacent ends of These shafts are in line with thedriw 6o ingfshaft or pulley-shaft 1-3,..extendi`ng from pivotall-y 65 mounted at 21 clutch-levers 22 whose inner l35, .said 'clutch-vlevers.'being. 80 y 14., 15 represent a pair of flanges integral with the web, extending on opposite sides thereof, vand concentric with the periphery of the pulley, said pair constituting practically a double flange.

the shafts 13, 16, and is rigid with the latter, Y and thus imparts rotation to said shaft 16%/ .and communicates power tothe loom 'or 110l otherpnachine on that side. The shaft 17 however remains stationary, as the clutchmechanisms on the right side are outffen'- gagement with the flange and remain'stav tionary, and hence do not impart rotation to the collar 19 rigid on said shaft 17.v jIt .is evident therefore that in this mechanism, like that described in the Letters Patent numbered 420,160 above referred to, power mayl be i parted to one orfboth or neither of the shaf s 16 and'17. In thisI invention however the two sets of clutch-mechanisms are en-l gag d, one or both at a time, by one orboth of the concentric flanges 14 and 15, which are within the general limits of the very heavy central driving-Pulley 10,andvbeing integral- With the web o said pulley constitute prac# tically a double flange. This'brings the fric# tion-yokes Within the general limits of the pulley on opposite sides of theweb, and not only simplifies the mechanism but central-v izes the power, producing a much better balance, and providing a stiffer and mucli more compact power-shipping mechanism, preventing the shafts 16, 17 from getting out of line with the shaft 13 and twisting or bending.

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

1. In a power-shipping Lmechanism of the character described, a central driving-shaft, a central driving-pulley rigid on said shaft, a pair of flanges concentric with the periphery 0f the pulleyand extending outward from opposite sides of the web between the hub and the periphery, curved yokes on opposite sides of the Web of the pulley concentric with the flanges, a pair of oppositely extending main shafts in line with the central shaft,

. sense? collars onl and' rigid with said main shafts and exten ing from the inner ends thereof around the outer ends ofthe central shaft, clutchymechanisms. pivotally connected with said collars and intermediate of the yokes on the opposite sides. of the driving-pulleyand the two main shafts, and means for operating said,-clutch-mechanisms and moving the a heavy central driving-pulleyfrigid on said shaft, a`v pair offlanges concentric with the periphery ofthe pnlley and extending out- Wardfrom opposite sides of the web between thehub and the/periphery, curved/yokes on oppositejsidesof theweb of the pulley within the generalvlmits thereof and concentric with the flanges, a pair of oppositely extending' main shafts in line with the central shaft, collars on andrigid with said main shafts and extending'from the inner ends thereof around ,tlfe outer ends of the central shaft, olutchf'mechanisms pivotally connected with said collarsfand intermediate of the yokes on the opposite sides ofthe driving-pulley and the two main shafts, and means for operating said clutch-mechanisms and moving the yokes into engagement with the flanges, for the purpose set forth.'

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
