GEORG-E GOODLINE, OF PHILADELPHIA, PENNSYLVANIA.

SPECIFICATION forming art of Letters Patent No. 744,683, dated. November 17, 1903.

Original application filed December 10,1901, Serial No. 85,306. Divided and this application filed December 17,1902. Serial Ito-135,516. (No model.)

To all whom it may concern:

Be it known that I, GEORGE GoonLINE, a citizen of the United States, residingin Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Shuttle-Box Opcrating Mechanism for Looms; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

proper for box-motions for looms. In anothercopending application, filed December 10, 1901, Serial No. 85,306, (and of which this application is a division,) I have set forth and claimed a novel mechanism for transmitting the action of the call mechanism to the boxes.

The present invention therefore consists in certain combinations and arrangements of parts found in the'said copending applicat ions. v

The present invention further consists in certain combinations and arrangements of. parts of the said call mechanism and of a mechanism which may be used to actuate said call mechanism, and which I have fully set forth and claimed in United States Letters Patent No. 685,420, dated October 29, 1901.

In the accompanying drawings my invention will be found fully illustrated.

Figure 1 is a side view of a box-loom provided with my improved box-operating mechanism; Fig. 2,a top plan view of said boxoperating mechanism with certain parts removed; Fig. 3, an enlarged side view of the mechanism, the lowerportion thereof being removed; Fig. 4,a view in front elevation of certain parts from which an alternating reciprocating and dwell movement is secured;

Fig. 5, a view of the lower portion of the box-operating mechanism-ed. e., thatportion thereof which is removed from the mechanism shown in Fig. 3; Figs. 6, 7, and 8, detail views of one of the call-gears and its accessory parts, and Fig. 9 a View of a certain stop mechanism for the call-gears.

' a is a loom side; I), the loom crank-shaft;

c, geari ng connecting the shaft 1) and the camshaft d, and e a bracket or stand which supports myimproved box-operating mechanism.

Arranged to slide against the front face of a vertical part f of stand e is a vertically-movable part g, which in its upper portion has teeth It on its'two side edges, thus forming a rack. The lower end ofthis rack carries a stud 2', extending through a slot in partf, while its upper portion has a vertical slot is,

penetrated by a stationary bolt Z'on stand 6.-

stud 7;, according to a definite scheme. A full,

clear, and exact description of the construction'and operation of these parts is set forth in said patent, and so it isunnecessary herein. The motion derivable from said parts, being one which is positive and susceptible of variation, so as to secure different relative lengths of reciprocations and dwells,'is one which is well adapted for actuating rack g.

19 represents auxiliary brackets projecting outwardly from stand e. In alined bearings g r in stand e and brackets 10 are journaled horizontal shafts 8. On each shaft is secured rigidly a call-gear t, which call-gear, being mutilated by having diametrically-opposed portions thereof removed, abuts with its hub:

against stand 9. 0n the inner end of each shafts is rigidly secured a stop-disku, each having two diametrically-opposed s'ectionally half-round lugs v. The outer end of each shafts carries a hand-Wheel w. Between the bearing 7" and each call-gear 25 is arranged to slide on the shaft a sleeve 0:, having an annular groove y and carrying two arms 2, formed so as to fit into the cut-out portions of the call-gears into which they extend. On arms z are mounted toothed segments 1 2, corresponding to the sections of teeth removed from the call-gears. Segments 1 2, are not directly opposed to each other, but are preferably arranged the one on one side and the other on the other side of a plane (indicated by a dotted line in Fig. 8) which is perpendicular to the shaft 8. gear and segments form an endless engaging surface portions of which (the segments) are movable to form breaks or recesses in said surface. On studs 3, arranged in the upper portion of stand 6, are fulcrumed bell-crank stop-levers 4, two of the corresponding arms of which are drawn toward each other by a spiral spring 5, while each of the other arms of said levers is formed with an integral shoe 6, taking against the lugs 11 of the stop-disks u and acting to hold the call-gears positively stationary. These coacting stop-levers and stop-disks keep the call-gears positively stationary and firm between actuations. In the brackets 79 is journaled a shaft 7, carrying

forks

8 and 9, having diametrically-opposed pins 10, which engage the grooves y of the corresponding sleeves as. Fork 8 is rigidly secured on shaft 7, while fork 9 is arranged to turn thereon. To fork 9 is secured a lever 11, and to the adjoining end of shaft 7 is secured another and substantially similar lever 12. Thus in an obvious manner the levers are adapted through the forks to shift the sleeves. Wires, rods, or the like 13 may be used to actuate the levers so as to move them in the one direction, while gravity may be depended upon to move them in the other direction.

From eccentrically-disposed pivots 14 on the stop-disks u are suspended rods 15, one for each disk. Between the lower ends of these rods is a floating or bodily-movable wheel or pulley 16, peripherally grooved, as at 17. Said groove receives straps or hands 18 19, the latter extending over the pulley, while the formerextends under it, their ends being secured to the rods, as shown in Fig. 1. In order to render the throw of one rod Variable, the pivot 14 thereof is arranged in a slot 20 of the corresponding stop-disk. In order to adjust the bands, one end of, say, band 19 is connected to one of the rods 15 by a threaded book 22, secured to said rod by nuts 23. The groove in the pulleyalso receives and guides each rod.

24 is the box-rod lever, fulcrumed at a stationary point 25 on the loom side and having one of its ends formed with a slot 26, receiving the stud 27 of the pulley. The other end of said lever has a slot 28, receiving a stud 29 on the lower end of a pitman 29, connected with the box-rod 30, which latter The assembled call-.

is guided in brackets 31 and carries the shuttle-boxes 32.

The mechanism operates thus: Shaft b being rotated continuously, through parts 172 and n is transmitted an alternating reciprocating and dwell movement to rack g. It will be observed that the stop-levers and stop-disks normally hold the call-gears, with their cutout portions,in the same horizontal plane, the arms 2 of sleeves as being received by said cut-out portions. The toothed segments are likewise held horizontal. If a previous actuation of fork 8 9 has moved the toothed segments on sleeve a: so that the one which is next adjacent rack g is thrown completely out of the plane of the call-gear, rack g will reciprocate without actuating the call-gear; but if the pattern so moves the fork through the connecting means 13 that said segment is thrownback completely into the cut-out portion of the call-gear the rack will turn the call-gear a half-revolution. The rack will not turn the gear more than a half-revolution,because when one toothed segment comes into the plane of the gear the other is thrown out of said plane, thus producing a space in the call-gear, so that so long as the toothed segments are not again moved the rack will continue reciprocating without actuating the call-gear. Thus each rod can oscillate with alternating dwells Variable at will. The ac tion of the pattern mechanism in efiecting the shifting of the segments occurs between the movements of the rack. Hence the importance of having the rack so work that between its movements dwells occur, giving the pattern mechanism opportunity to act. The up-and-down movement of either or both of rods 15 of course moves pulley 16. 1f the pivotal connection between one rod 15 and the corresponding stop-disk u is further removed from the center of rotation of said disk than that between the other rod and stop-disk, the mechanism will be susceptible of imparting four separate positions to pulley 16. The uppermost position is that where the two rods are in their extreme elevated positions. Another is where the right-hand rod is up while the left-hand rod is down. Still another is where the right-hand rod is down while the left-hand rod is up, the position which this movement imparts to the pulley being different from the previous one, because since the pivotal points of the rods are difierently disposed in their respective stop-disks one has a greater throw than the other, and the last position is where both rods are down. Of course as the pulley is moved it imparts its movement to lever 24, which in turn transmits motion to the boxes.

It will be noticed that the segments 1 2 are not only arranged on opposite sides of a plane perpendicular to the axis of the sleeve m, but that they are close to said plane. Thus the pattern from which the segments are controlled may act to shift the segments so that half of each is received by the corresponding cut-out portions of the call-gea r. of this is to render it possible to make the boxes work pick and pick with reference to any two boxes without having to resort to the pattern mechanism as an initial means for setting the two boxes involved each time each comes into use-v 6., every alternate pick of the loom.
