signor of twelve and one fourth-per cent to De Leon A. Prosser,
The present invention relates to new and useful improvements inshuttle motionsforglooms, and has for its primary'object to provide, in a manner as hereinaftersetforth, ashuttle motion embodying a novel construction, combination and arrangement of parts through-the medium of 'which the shuttle willbe positively drivenand under constant control duringits entire travel 'tion through a portion of theshuttle motion,
through the shed. Other objects of the invention "are to provide a shuttle'motion for looms which will "becomparatively simple in construction, strong; durable, highly efficient and reliable in operation "which may be manufactured at low cost. "All ofthe foregoing and still further objects and advantages of the invention will-become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate correspondingpar-ts throughout the several views; ahd-whereinzi Ti Figure "1 is a view in front elevation of a shuttle motion in [accordance "with the present'invem tion." r r a FigureZ is a view in vertical longitudinal sectaken substantially on theline 2--2 of Figure 3.
Figure 3 is a view in vertical transverse section, taken substantially on the line 3 -.-3 of Figure 1. Figure 4 isa View in vertical transverse section; taken substantially on the line 4- 4 ofFig- N'Figure-fi is a detail view in horizontal section 'throughthe shuttle, line 5-5 of Figure 1. i I Figure 6 is a fragmentary view ot-an intermediate portion of the lay, said view being partially in top plan'and partially in horizontal section on the line-6-B inFigure lof the drawings. Figure '7 is a horizontal sectional view, taken substantially on the line (-1- of Figure 1.
Figure 8--is a detail view in perspective of the substantially channel-shaped face plate constituting a part of the cam.
Figure 9 is a detail view in perspective of'one of the vertically reciprocating shuttle actuating pins. r s Figure 10 is a'detail View in perspective of one of the pin guides.
Figure 11 is a detal view in perspective of one of the pin weights.
Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a lay which is designated generally by the reference numeral Petersburg,
and one-fourth per cent .to John. H. Ryalls,
, twelve and4one-fourth per centandtwelve and one-fourth per cent to RtWinfston llabney, all. of Richmond, Va.
Application October- 4, 1933, Serial No. 692,172
' iclaiins wig139-133 andfis a seriesjof guides" 1 having "said heads in elevated taken 7 substantially on the *mitted to return substantially tubular or Va., and twelve l,said lay includinga pair I may be mounted for swinging movement in the V usual manner. Extending between the lay swords lower rails 3-and 4, respectively,
Zare upper and V betweenwhich a shuttle which is'designated generally by the reference numeral 5 is mounted for travel.
As illustrated to advantage in Figures 3 and ofithe drawings,the lower rail 4 is of hollow or substantially tubular form to receive lubricatmg oil substantially to the level'indicated' by the broken line 6 .Mounted vertically in the lower rail 4 slidably mounted therein shuttle actuating pins 8, said guides! having ports 9 therein for the passage of the lubricating oil to said pins 8. The guides Tproject above the railt for engagement with heads Ill on the upper ends of the pins 8, thus supporting position relative to the rail 4. Polygonalweights ll are secured on the "lower endportio'ns of the pins 8 beneath ther'ail 4 by set screws !2. As will be apparent the weights ll constitute means for assuringthe return of the pins 8 to lowered position by gravity.
Also extending between the lay swords 2, in spaced relation beneath the lower rail 4, is a. track l3 upon which a cam is mounted for reciprocation, said cam being designated generally by the reference numeral Hi. The cam l4 comprises a block 15 which is mounted on asupportingj arm l6, said supporting arm l6 being slidable on the track [3. Mounted on top of the block I5 is 'a face of lay swords 2 which plate in the form of a channel member ll through which the weights ll ride when the cam I4 is actuated. It will thus be seen that the pins 8 are successively elevated and retained in elevated position for a'brief length -of time and then per- V to lowered position as the cam I4 is moved along the track l3.
The cam I4 is reciprocated on the track [3 through themedium of cables which are windable on drums 19 on thelay swords 1 The cables l8. are connected, at one end, to an eye 20 which project from the supporting arm l6 of the cam It. Any suitable means may be provided for alternately rotating the drums 19 in opposite directions for shifting the cam l4 back and forth on the lay in time with the operation of the loom. Mounted beneath the track I3 is a trough 2| for catching excess oil which may drip from said track [3. It may be well to here mention that oil from the reservoir 22 which is formed by the hollow lower rail 4 flows by gravity down the pins 8 in a manner to lubricate the cam I4 and the track l3 as said cam travels thereover. Attention is also invited to the fact that the polygonal weights II are slidably engaged with each other inside abutting relation in a manner to prevent lateral movement or wobbling of the pins 8, as illustrated to advantage in Figure 20f the drawings.
The shuttle includes a pair of spaced, opposed, substantially U-shaped frame members 23 between which upper and lower pairs of grooved wheels 24 and 25, respectively, are journaled. Mounted on one of the frame members 23 is a suitable support 26 for the bobbin 21. The weft 28 from the bobbin 2'! is kept taut during'the'operation of the loom by a pairlof co-acting, resilient jaws 29 which are mounted on a projec tion 30 on one of the frame-members 23, said weft passing between the resilient jaws, as best seen in Figure 3 of the drawings. The grooved lower wheels 25 of the shuttle 5 are mounted for travel on the heads ID of the pins 8. I
v Thegrooved upper wheels 24 of the shuttle 5 are operatively engaged with spaced lugs or corrugations 31 which depend from the upper rail 3. It will thus be seen that the construction and arrangement are such that the shuttle 5 is retained in a vertical position between the upper and lower rails 3 and 4. It will also be seen that the shuttle 5 is. mounted to travel between the warps 32,"said warps, in turn, passing between the corrugations 3! of the upper rail 3 and the projecting upper end portions of the guides l on the lower rail 4.-
Briefly, the operation or" the invention is as ',follows: a
:As'the cam I 4 is moved back and forth on its track 13, the pins 8 are successively elevated in,
the manner suggested in Figure 2 of the drawings for engagement withone of the lower wheels 25 for driving the shuttle 5 in the direction in which said cam is traveling. As the cam M passes :from beneath the pins 8,'thereby permitting said .pins to drop to lowered position, the returning pins engage the trailing wheel 25 and the shuttle 5-is in this manner retained at all times against lidle movement between the rails 3 and '4. It will thus 'be seen that the shuttle 5 may be positively brought to a stop at any point in the shed simultaneously with the stopping of the cam M.
It is believed that the many advantages of a shuttle motion for looms in accordance with the "present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and "described, it is to "be-understood that 'changes'in the details of con- .struction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:
1. A shuttle motion for looms comprising spaced rails, a wheeled shuttle operable between the rails, pinsmounted'for verticalreciprocation on one of the rails and operatively engageable with certain of the wheels of the shuttle for actuating said operable between, the rails, tubular guides mounted vertically in the lower rail, pins slidable in the guides and engageable with certain of the wheels of the shuttle for actuating said shuttle, means for successively elevating the pins, the guides projecting above the lower rail for the passage of the lower warps therebetween, and
corrugations depending from the upper rail and operatively engaged by the other wheels of .the shuttle, said corrugations defining passages for the upper warps beneath the upper-rail.
