SHUTTLE-Guano.

Specification of Letters Patent.

Patented Application filed April 12, 1915. Serial N 0. 520,318.

To all whom it may concern:

Be it known that I, Josnrrr I. LANDRY, a citizen of the United States, and resident of Uxb'ridge, in the county of Worcester d State. of Massachusetts, have invented certain new and useful Improvements in Shuttle-Guards, of which the following is a specification.

This invention relates to shuttle guards for looms, and its object is to provide a shuttle guard of the type that is automatically. movable into guarding position when the loom is being started, and automatically movable away from guarding position when the loom is being stopped.

Of the accompanying drawings:

Figure l is a side elevation, partly in vertical section, showing enough of the mechanism adjacent the right-hand end frame of a loom in which my improved shuttleguard mechanism is embodied, to give a clear understanding of the invention.

Fig. 2 is a View showing in front elevation my improved shuttle guard.

Fig. 3 is a top shown in Fig. 3.

Fig. 4 is a detail view, on a larger scale, of the rack and pinion shown in Fig. 1.

The same reference characters indicate the same or similar parts Wherever they occur. The righthand end frame of the loom is indicated at 8, the lay at 9, change shuttle plan view of the parts boxes at 10 and 11, the reed at 12, anda I of the end frame, tending lay sword at 13 mounted on a rockshaft 14 which has a bearing in the frame 8. A crank arm or pitman by which the lay is oscillated is indicated at 15. The hand rail or reed cap is indicated at 16. The foregoing partsare' common andwell known and will require no further description.

A hand lever or shipping lever by which the loom is started and stopped is indicated at 17. This lever is mounted at the outer side of the end frame 8, on a rockshaft 18 which has a bearing in the end frame. Affixed on the rockshaft 18, on the inner is a slotted lever 19. from the slotted lever 19, to which it is adjustably secured, is a link rod 20 the lower end of which is pivoted to a lever 22 fulcruined at 23 and having at its free end a roll 40 which, as presently described, acts upon the lower end 39 of a pendent arm 38 to raise the shuttle guard when the loom is being stopped. The shuttle guard comshaft 35 so the" the side.

prises a plate 25 (Figs. 1, 2, and 3) having an arm or lug" 26 at each end pivotally mounted upon a shaft 27 mounted on the lay 9. A small pinion or toothed member 28 arranged to rotate on shaft 27 is connected with the arm or lug 26 in any suitablemanher so as to insure the rocking or tilting of the guard plate 25 relatively to the axis of the shaft 27 whenever the pinion or toothed member 28 is rotated. To so rotate the pinion or toothed member 28 I provide a rack 29 (see Figs. 1 and at) having a depending arm 30 mounted in a step bearing 31, which latter is formed so as to permit the arm 30 to rock when the rack is reciprocated underthe pinion 28, said rack bein located below the hand rail 15 of the lay.

The rack 29 has an upwardly projecting pin 32 which enters a fork or yoke 33 projecting laterally from an arm 34:, which lat ter extends upwardly from a rockshaft 35 mounted in cars 36 carried by the lay. The rockshaft 35 has another arm 37, projecting rearwardly, an arm 38 having a curved lower end or foot 39 depending from said arm 37. The curved foot 39 is above the roll 40 and therefore when the loom is stopped by movement of shipping lever 17 in the direction of the arrow (Fig. 1), the roll 40 rises as hereinbefore explained, the upward movement of the arm 38 rocks the embers 33, 34 of the latter will on t rack 29 in a direction so that it will tilt or rock the shuttle guard from the position shown in Figs. 1 and 2, the front edge of the guard swinging upwardly and therefore enabling a shuttle to be removed from the lay if desired and giving access'to the reed for the drawing in of broken warp threads when necessary. When the loom is in operation the guard 25 occupies substantially the inclined position shown in Fig. 1. I prefer to have themembers 19 and 20 so adjusted that when the loom is being stopped the guard 25 will be moved about the axis of the shaft 27' so that the front edge of the guard will be brought as close to the hand rail 16 as is practicable without incurringany danger of stripping the teeth of the rack, or, in other words, the guard will. be moved to a position where it will least obstruct access to the reed.

I claim:

In a loom, a shuttle guard comprising a pin 32 to move the plate pivotnlly supported on the lay and having a pinion, a rack engaging said pinion, a i'ockshaft having an arm and connections whereby movements of the rockshnft will reciprocate the rack, said rockshaft having another arm and a pendant from the latter, a lever adapted to shift said pendant and through it rock the shaft and move the rack, and a hand lever having connections for actuating the lever which 1' acts upon said pendant,

In testimony whereof I have affixed my slgnnture, 1n presence of two witnesses.

JOSEPH P. LANDRY.
