PICKING SWEEP-STRAP CONNECTION For: LOOM'S.

EPECIPICATION forming part'of Letters Patent No. 382.6 dated y 1888- Application filed May 10, 1887. Serial No. 237.090. (No model.)

To all whom it, may concern.-

Be it known that I, EDWIN H. J. FIELDER, of the city and county of Providence, and

State of Rhode Island, have invented certain new and useful Improvements in Picking Sweep-Strap Connections for Looms, of which the following'is a full, clear, and exact description, reference being had to the accomdrawings, forming part of this specification.

This inventionrelates to an attachment of a loom called a sweep-strap connection, WhlCh s the device connecting the pickerstatf with the sweep-strap, and by means of which the staff is drawn inwardly to drive the shuttle.

The old forms of leather sweep-strap connectlons are very perishable and the constant replacement of them becomes troublesome and expenslve.

The objects of my invention are to provide a durable and efficient sweep-strap connection, which will form a permanent at-tachment'of the loom. I

To the above purposes my invention conslsts 1n the certain peculiar and novel parts of the device, all constructedand arranged as hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a front view of a portion of the end of a loom upon which is mounted an ordinary picker-staff and sweep.- strap, which are connected by my improved strap-connection. The picker-staff and sweepstrap are both showmin part. Fig. 2 is an enlarged side view of portions of the sweepstrap and staff with mysweep-trap connection attached. Fig. 3 is an end view of Fig. 2,with the outer end of the strap-connection broken off to show the guiding-lugs on the pickerstaft. Fig. 4 is a top view of Fig. 2. Fig. .5 1s a wow similar to the view in Fig. 4 of another form of my sweep-strap connection.

In the said drawings like numbers of referentce designate corresponding parts throughon Referring to the drawings, the number 7 designates the loom-frame, in which is pivoted near its lower end the ordinary picker-staff, 8, which is shown as broken off atthe top. The

- picker-staff is kept normally forced to the outward limit of its throw by means'of' the usual. spring, 9, and connection .10 at its foot.

The picker-staff is jerked-inward by the inward movement of the sweep-strap 11, which may be operated in the usual manner.

My improvements comprise the connections between the picker-staff andsweep-strap, as will now be described.

The sweep-strap connection is composed of so the two flat oblong members 12, which are each secured by their inner ends to the end of the sweep-strap 11 by means'of the tie-bolt 14:, and project in alignment with the sweep-strap and parallel to each other. At the outer ends the members are each provided with a spacing piece, 13. The members are placed apart, so

so as to form the slot 18 for the staff to vibrate in. Each member.- 12 is formed with ahorizontal guideway or opening, 15, the two openings 15 lying directly opposite each. other.

The plate l6.is secured, by means of screws or otherwise, upon one face of the picker-staff 8, and is provided with the lateral guidinglugs 17, which work in the guideways 15 of the strap connection 12. As the picker-staff is drawn by the movement of the sweep-strap, the strap-connection pulls the picker-staff inwardly by virtue of the lugs 17 which remain in the same position as shown in the drawings during the inward movement. .When the sweep-strap 11 is then moved suddenly outward, the guideways 15'slide over the lugs,

the picker-staff outwardly as quick as the sweep-strap 11 is thrust outward.

In Fig. 5 Ihave'shown another form of the strap-connection 12, which may be cast integral with the sweepstrap 11,'and the two members thereof are spaced so as to form the .slot 18. In other respects the strap-connec-v tion is similar to the one described in the other figures.

sincethe action of the spring 9 does not move The strap-connection 12 and the plate 16 1 and the guidinglugs 17 may all be made out of metal, and the parts will be as durable as many other parts of the loo'in, and one strap will last during the life of the loom.

' Having thus described myinvention, I claim as new and desire to secure by Letters Patent-'- The combination, as hereinbefore set forth, formed with the lateral guideways 15 for the with the picker-staff 8, having secured thereto lugs 17, substantially as and for the purpose the plate 16, provided with the lugs17, of the herein described.
