SHUTTLE FOR AUTOMATIC FILLING-REPLENISHIIFIG LOOMS.

SPECIFICATION forming part of Letters Patent No. 782,505, dated February 14, 1905.

Application filed December 14,1904. Serial No. 236,787.

To all whom it may concern:

Be it known that I, OSCAR J ANELL'E, a citizen of the United States,and a resident of Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in Shuttles for Automatic l illing-Re 'ilenishing Looms, of whichthe following description, in connection with the accompanying drawings, is a specification, like figures on the drawings representing like parts.

ln the'Northrop type of automatic fillingrepleuishing loom, an example of which is shown and described in United StatesPatent No. 5529,9 10, the heads-of the filling-carriers are provided with metallic annular projections or rings which enter upright notches formed in the inner faces of spring-acting holdingjaws mounted in the shuttle at one end of the chamber in which the filling-carrier enters. The loom is provided with mechanism to automatically remove the filling-carriers one by one from a feeder and transfer them to the running shuttle whenever a change of filling is called for, the operation of the replenishing mechanism being very rapid and forcible in order to properly insert the head of the incoming filling-carrier in the jaws and eject therefrom the filling-carrier .then held by the jaws. The shuttle used in such looms is provided with an inclined guide located between the bases of the jaws to engage the butt of the incoming filling-carrier when the notches of the. jaws. are not in the proper position to receive the rings and efl'cct relative. longitudinal movement of shuttle and filling-carrier to bring the rings and notches into proper cooperating position At such times the butt of the filling-carrier or bobbin strikes the guide with great force, the blow tending .to split, crush, or otherwise injure the butt, it being remembered that owing to the chamber in the head the walls of the buttare relatively thin and ill adapted to resist the shock due' to such initial impact.

My present invention has for its object the production of means to receive the impact of the incoming filling-carrier by or through engugement with the rings on the head, whereby the force of the blow is taken up by the rings independently of the butt, thereby protecting the latter from in ury.

fully described in the subjoined specification and particularly pointed out in the following claims.

the line 1 1, Fig.2, of the holding end of a loom-shuttle with one embodiment of myining filling-carrier being shown in dotted lines to illustrate the manner in which the invention operates. Fig. 2 is a top or plan view of the portion of the shuttle shown in Fig. 1. Fig. 3 is a perspective view detached of the impact members or buffers and their support. Fig. 4 is a top or plan view of a portion of a shuttle, .howing another form of my invenon the line 5 5, Fig. 4; and Fig. 6 is a similar view showing the impact members or buifers attached directly to the holding-jaws.

1, having a chamber 2 formed therein and extending from its toplto its bottom to receive the filling-carrier or bobbin,the spring-holding jaws 3, rigidly secured to the shuttle at one end of the chamber 2 and having upright notches 4 in their inner faces to receive" the rings 5 on the head 6 of the filling-carrier, (see dotted lines, Fig. 1,) and the inclined guide 7 located between the bases of the jaws, maybe a r d are all of well-known construction in shuttlhs used in connection with looms of the-type referred to. j p

i In the embodiment of my invention illustrated in Figs. 1, 2, and 3 I provide camshaped impact members or buffers 8, made of metal and having their upper edges 9 inclined forward and downward, the said members being connected by "a cross-piece 10, passed under the guide 7 and rigidly secured thereto in any suitable manner, as by a rivet 11. The bufiers areslightly flared, as shown in Fig. 2, and lie closeto the inner faces of the jaws back of the notches 4, the cam faces or edges 9 leading downward to the upper ends of the rearmost notches, Fig. 1:. The buffers are so positioned that if the shuttle is not properly In Figs. 1 and 2 and 4; to 6 the shuttle-body The novel features of my inventiomwill be i Figure l is a longitudinal sectional view on vention applied thereto, the head of an incomtion. Fig. 5 is a longitudinal section thereof positioned for the reception of the incoming Killing-carrier, as in Fig. 1, the rings :3 thereof will initially engage the cam-surfaces 9 before t 5 rings slide along the cam-surfacesi) i illin pact occurs.

in the modihcation shown in Figs. and 5 the cam-surfaces 13 are formed on the ends of of the notches L. The guide 7 extends between the arms 1%, as clearly shown in Fig. i,

v, iongitudii'nil movementof the shut- ,rricr, and the are diing-carricr through engagement with the rings thereof independent of the butt and thereby protect the butt from injury.

In ashuttle'forautomatic lillingreplenishing looms, holding-jaws notched to receive I the rings on the head of a filling-carrier, and

ng or directing movement the butt 1 cor'ipcrate with the guide after initial immeans back of the notched portions of thejaws and separate therefrom to receive the initial 1 impact of the incoming filling-carrier by engagement with the rings thereof and thereby i prevent crushing or'jamming of the butt. the arms 1% of a substantially if-shaped support, the stem 15 of which tits into the space between the bases of the holding-jaws 3. the arms being held by their own resiliency in contact with the inner faces of the jaws back l and the cam-surfaces 125 act through cngage- 1 mcnt with the rings of the incoming iillingcarrier, as before described, to receive the initial impact, and thereby prevent injury to the butt.

in both of the forms of my invention thus far described the butfers or impact members are supported separately from the holdingjaws; but, if desired, the buffers may be se cured directly to the jaws, as shown in Fig. 6, wherein the heifers are-shown as metallic cars 16, riveted at 1? to the jaws and having camsurfacc's 18 to engage the bobbin-rings, and thereby take the impactof the blow. So far as i have been able to determine the initial impact of the butt of the bobbin on the inclined guide causes injury, due to the sudden hard blow, whereas if the initial impact of the incoming bobbin or filling-carrier is received by meansindependently of the butt the latter will not be injured if it afterward slides along the guide.

it .will be manifest from the foregoing description, taken in connection with the drawing, that if the shuttle isproperly positioned to receive tne incoming filhng-carrier the impact members or buffers will not'be called into operation.

3 in a shuttle for automatic filling-replenishii'igloonis, holding-jaws notched to receive the rings on the head of a filling-carrier, and cam-shaped buffers adjacent the rear ends of the jaws and back of the notches thereof to receive the initial impact of the incoming fillingcarrier by engagement with the rings thereof, to thereby protect the butt fro 111 injury and 5 guide the rings into the notches.

4. In ashuttle for automatic filling-replenishing looms, holding-jaws notched to receive "therings on the head of a filling-carr.icr, an inclined guide between the bases of the jaws, 1 and impact members at the sides of the guide back of the notched portions of the jaws to receive the initial impact of the incoming fillingcarrier by engagement with the rings thereof prior to cooperation of the butt with the guide, to prevent fracture of the butt.

In a shuttle for automatic filling-replenishing looms, holding-jaws notched to receive the rings on the head of a filling carrier, camshaped buti'crs adjacent the rear ends of the jaws and back ot' th'e notches, thereof, to receive the initiai impact of the incoming fillingcarrier by engagement with the rings thereof, and a support for the bufiers separate from the jaws.

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