Specification of Letters Patent.

Application lred .T une 26, 1908. Serial N o. 440,518.
T o all 'wh-0m t may concern:
Be it known that I, DAVID E. GRAY, a citizenof the United States, residing at White Plains, in the county of Westchester and State' of New York, have invented certain new and useful Improvements in Shuttle and Picker-Stick Checks, of which the following is a specification. j
My invention relates to a checking device for the shuttle and picker stick.
Heretofore it has been common to stop 4or check the picker stick in its forward movement by a bumper more or less yielding in character and to check it in its backward movement either by friction applied directly to the stick or by a long strap con? necting the opposite shuttle boxes and passing around the two sticks. Such devices or their use consume or necessitate a great deal of power, cause wear and tearon the parts of the machine and make a great deal of noise.
It is my object to reduce the power required to operate, to avoid noise, vibration and wear and tear and to provide a device which is inexpensive and yet eflicient and durable. Incidentally it will be found to be compact and adapted to a great variety of types of looms.
Briefly described it comprises in its simplest and most complete form, a movable checkingy loop in which the picker stick oscillates. Guides are provided for the loop some of which are adjustable to aord the proper resistance to the movement of the loop.
The accompanying single sheet of drawings illustrates one form of .the invention but it will be understood that I do not consider the invention as limited or specific in its scope any more than will be hereinafter set fort-h in the claims. y
Figure l is a side View of parts of a loom illust-rating my invention, the picker stick and shuttle being shown in full lines in their backward position and in dotted lines in the forward position. `F ig. 2 is a bottom view of the parts in the full line position of Fig. 1. Fig. 3 is an end view and a partial verti: cal section on the plane of the line X X Fig. 1 looking in t-he direction of the arrows.
The picker stick 1 is operated in any suitable manner and the picker 2 operates the shuttle 3 as usual. The support 4 which in the ordinary loom is one end of the lay carries the shuttle box 5. The usual binder 6 may be used if desired.
On opposite sides of the support 4 are secured frames 7 and 8 having hook- like guide fingers 9, 10, 1l and 12. The checking device 13 is in the form of a strap which passes around the picker stick and the fingers 9, 10, 11 and 12. The lateral guides 14 and 15 areadjustable in and out relative to the end guides -so as to make it possible to increase or diminish the 'friction of the checking loop. For this purpose the flange friction of the loop on the guides retards' the loop and thus brings the stick to rest without excessive shock vin the position shown dotted in Fignl. The action is just the reverse on the backward stroke of the picker stick. The friction of the loop on the guides is sufficient in fact to stop the picker stick before it reaches the rear end of its stroke. This leaves the picker in a position just above the rear guides 9 and 11. The shuttle on vits return hits the picker and drives the stick backward to the full line position of Fig. 1. The loop thus indirectly checks the shuttle. It is therefore not necessary to adjust the binder '6 as tight as it ordinarily is. Less power is therefore required to throw the shuttle forward as there is less friction of the binder.
To facilitate assembling the attachment on the loom I prefer to securethe frame 7 and 8 to the support 4 by screws or bolts such as 19 and 2O which pass through slots in the sides of the frames. This permits the frames to be adjusted properly after thel bolts have been placed in an approximately correct position.
By the term picker stick I mean to include all devices of whatever shape or mode of operation which serve to throw the shuttle out of its box.
The yielding character o f the check prevents the severe shock formerly'encountered on the forwardstroke' of the pickerstick. There isthus less breakage of sticks with my attachment. The stick is also saved `16 of each frame is slotted and the base of laterally, a checking strap passing around.
said guides and lateral guides outside o the checking strap and between the end guides, one or more of said guides being laterally adjustable relative to the others for varying l the effective length of the strap.
2. A checking device for a loom comprising two pairs of end guides spaced apart laterally, a checking strap passing aroundA said guides and lateral guides outside of the checking strap and. between the end guides, said lateral guides being adjustable toward and from each other.
3. A checking device for a loom comprising a strap, two pairs of end guides therefor, a guide between the guides of each pair of end guides and adjustable with relation thereto for varying the efective length of said strap.
4. A checking devicefor a loom comprising, a traveling checking strap in the form of a loop, guides therefor, one or more of said guides being adjustable with relation to the others for varying the effective length of the strap.
5. A checking device for a loom com rising, a traveling checking strap in the orm of a loop, guides therefor, two of said guides being adjustable with relation to the others for varying the eective length of the strap.
6. In a checking device fora loom, a pair of side lplates having depending guide fingers with outwardly flaring shoulders, a
traveling checking strap supported thereon, and lateral guides within the line of said guide fingers for holding the strap on said ngers.
7. In. a checking device for a loom, a lay, guide fingers carried thereby and adjustable along the length thereof, a traveling checking stra supported thereon and lateral guides a justable relative to said supporting guide fingers for varying the efvfective length of the strap.
8. In a checking device for a loom, two pairs of guide lingers, a ltraveling checking loop around said guide fingers and a pair of guide Ifingers arranged ,outside of said loop and against which said loop is drawn when in operation, some of said guidelingers having laterally Haring flanges for supporting said loop.
9. In a checking device for a loom, a pluralit of interior guide lingers, a traveling chec ing loop surrounding said guide ngers', a pair of external guide members coacting-With the outer surface of said loop and laterally slotted supports for said guide members whereby said guide members may be laterally adjusted.
10. In a checking device for a loom,
plurality of'interior guide ngers, a traveling checking loop surrounding said guide fingers, an external checking member frictionally engaging the outer surfaceof the loop at a point between the two of the interior guide` fingers at one side of the loop and means for supporting the loop in proper engagement with the guide fingers.
