SHUTTLE-ACTUAIING MECHANISM FOR LOOKS.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed August 27, 1917, Serial No. 188,266. Renewed February 14, 1921. Serial No. 445,014.

To all whom it may concern:

Be it known that I, RICHARD HAT'I'ERSLEY SMITH, a subject of the King of Great Britain, and resident of Keighley, in the county of York, England, have invented a certain new and useful Improvement in Shuttle- Act-uating Mechanism for Looms, of which the following description, having reference to the accompanying sheets of drawings, is a specification.

It relates to the arrangement and construction of the several devices forming the picking or shuttle actuating mechanism for looms of the type known as overpick picking mechanism and has for its object the production of said several devices of such-a character as will enable me to secure the benefits and advantages of the over-pick picking mechanism as to its functions, ease of actuation and the like; in conjunction with change box mechanism of the rising and falling type having the binders mounted at the front of the series of compartments of the shuttle box, thus said benefits and advantages are secured while further securing others by enabling the weaver more readily to manipulate the shuttle and attend to the replenishing of the weft or to carry out other desired adjustments which are permitted by making use of shuttle boxes havin the binders at the front.

In order that my said invention may be readily understood I have hereunto appended sheets of drawings illustrative thereof to which by figures and letters reference is made in the following description.

Figure 1 is a sectional end elevation of sufficient of a loom to illustrate the application of my improved parts.

Fig. 2 is a sectional front elevation taken on line A. B. of-Fig. 1 and as seen from the front of the loom.

Fig. 3 is a sectional front elevation of certain parts at the end of the loom to the left, illustrating the positions of my devices as hereinafter described.

C indicates the slay board of the loom, D the end frame of said loom and E the layswords, F a rotary shaft in said loom, G the picking cam and H the arm actuated by the said picking cam.

In carrying my invention into effect I arrange the shuttle boxes 2 so that the series of compartments have the binders 8 at the front of said shuttle boxes and toward the front of the loom, while the pickers 4 and their picker spindles 5, together with their guiding bars 6 are at the back of said shuttle boxes thus the picking strap 7, connecting a picker 4 to the picking stick 8, extends from the rear of the shuttle box to said picking stick by which arrangement the whole front of the shuttle box is left free and easy of access for the weaver.

The picking shafts 9 which are of the vertical type are arranged to be at an angle to the vertical plane taken longitudinally through the loom, as well as being inclined to the vertical plane taken crosswise said loom, so that as the oscillations of said shaft 9 and the parts that it carries are in such a direction or follow such a path as to cause the picking stick 8 to move from a lower position at the outer end of the slayboard to a higher as it is picking or throwing the shuttle and moving toward the interior of the loom, its directlon of motion is such that it holds the picking strap 7 at all times in a stretched condition from the time that said picking stick 8 commences to move until it is finally arrested at the extreme end of its path of motion and that notwithstanding the motions of the slay-board C.

Although I have hereinbefore described the arrangement of the picking shaft 9 in the inclined position as illustrated, as being used in a loom having multiple shuttle boxes it is obvious that I may make use of said arrangement of the picking shafts 9 in connection with single shuttle looms wherein advantages would accrue by making the picking stick follow the path of motion described.

Such being the nature and object of my said invention what I claim is 1. In shuttle actuating mechanism for a loom, a rotary shaft, a picking cam mounted.

on said shaft, a picking shaft arranged at an angle to the vertical plane, an arm carried by said shaft to be actuated by the picking cam, another arm fixed upon said shaft and extending approximately at right angles therefrom, a picking strap fixed upon said arm, a picker connected to said strap, guiding devices upon which said picker may slide and a shuttle box within which said picker operates.

2. In shuttle actuating mechanism for a 100m, a rotary shaft, a picking cam picking shaft at approximately right angles mounted on said shaft, a picking shaft arthereto, a picker, a strap secured to said ranged at an angle to the vertical plane in arm and to said picker, supports and guides 10 which the rotary shaft of the loom is situfor said picker and a shuttle box Within ated and also at an angle to the vertical which said picker operates.

plane in which the end frame of said 100111 is situated, an arm extending from said RICHARD HATTERSLEY SMITH.
