Original application filed December 10,1901, Serial No. 85.306I Divided and this application filed December 17, 1902. Serial No. 135.515l (Nemen.)
To all whom it may concern:
Be it known that I, GEORGE GooDLINE, a citizen of the United States, residingin Philadelphia, county of Philadelphia, andState of Pennsylvania, have invented certain new and useful Improvements in BOX-Motions f0r` Looms; and Ido hereby 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 ac# companying drawings, and to Vcharacters of reference marked thereon, which form a part of this specification. i
This invention relates to the construction of looms, and it has reference particularly to box-looms, having especially to do with that portion of the box-operating mechanism of such looms from which the selecting or calling of the boxes is directly accomplished.A The present application constitutes a division of an application led by me DecemberA l0, 1901, Serial No. 85,306.
My invention will be found fully illustrated in the accompanying drawings, wherein corresponding characters of reference indicate like parts, and wherein- Figure l is a side View of a box-loom provided with my improved box-operating mechanism. Fig. 2 is a top plan view of the said box-operating mechanism with the boxes, the box-rod, and the lever whereby motion is transmitted to the boxes removed; and Figs. 3, 4, 5, and 6 show one of the callgears and its accessory parts.
In said drawings, a designates a loom side,
e is ab'racket or stand,which constitutes the main support for my improved box-operating mechanism and which is preferablyv bolted to the loom side a. Arranged to slide against the front face of thevertical part f of said stand ve is a vertically-movable part g, which in its upper portion has its two side edges formed with teeth h, thus constituting a double rack. The lower end of this rack carries a stud e', which extends through a slotj in the part f, while theupper portion of said rack has a vertical slot lo, which is penetrated by a stationary bolt Z, extending from the stand c.
These bolts and slots afford a guiding means for the rack.
InV Letters Patent No. 685,420, dated October 29, 1901, I have described a mechanism wherebyV an alternating reciprocating .and dwell motion may be imparted to the rack g. The partsofthis mechanism are in the present case formed in a peripherally-grooved turnwith, the shaft b,and a connecting-rod n", which is provided at one end with'a pecul-` iarly-shaped claw o, adapted to engage the grooves of said disk and move' through the same in accordance with a ydefinite scheme, andhaving its otherv end pivoted on stud e'. A full andclear description of the construction and operation of these parts is fully set forth in the said patent, and so it is not necessary herein. The motion capable ofbeing derived from said parts being one which is positive and susceptible of variation, so as to securediIerent relative lengths of reciprocations and dwells, is one which is well adapted for 'actuating the rack g. 1
p designates 'a pair of auxiliary brackets, which are carried by the stand or. bracket e, projecting outwardly therefrom. In alined shafts s, On eachshaft is secured rigidly, so as to turn therewith, a call-gear t, which callgear, being mutilated by having diametrically-opposed portions (each preferably comprising fourteeth) removed, abuts with its `hub against the stand e. On the inner end of each yshaft s is rigidly secured y afstop-disk opposed sectionally half-round lugs or projections o extending from 011e of the faces thereof. The outer end of each shaft s carries a hand-wheel w, whereby the shaft may be manually turned'. Between the bearing r and each call-gear t is arranged to slide on the shaft s a sleeve m, having an annular groove y and carrying two arms z, formed so as to fit into the cut-out portions of the mutilated call-gears t, into which they extend. On the' arms z are mounted toothedA segments l 2, which correspond to the sections of teeth removed from the call-gears. The segments bearings q r in the stand e and brackets p, respectively, is journaled a pair of horizontal disk m, which is rigidlyvsecured on, so as to 1 u, each of said disks having two d iametrically- 1 2 are not directly opposed to each other, but they are preferably arranged the one directly on one side and the other directly on the other side of a plane (indicated by the dotted line in Fig. 5) which is perpendicular to the shaft s, for a reason hereinafter pointed out. On fulcruming-studs 3, arranged in the upper portion of the stand e, is fulcrumed a pair of bell-crank levers 4, which I term stoplevers, two of the corresponding arms of said levers being 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, adapted to take againstthe lugs or projections n of the stop-wheels u. By'these coacting stop-levers and stop-wheels the callgears are adapted to be held positively and firmly between actuations. The brackets p aEord bearings for a shaft 7, which carries forks S and 9, having diametrically-opposed pins 10, which engage the groovesy of the corresponding sleeves 00. The fork 8 is rigidly secured on the shaft 7, while the other fork is arranged to turn thereon. To the fork 9 is secured a lever 11, and to the adjoining end of the shaft 7 is secured another and substantially similar lever 12. Thus one lever is adapted to actuate one fork, so as to move the corresponding sleeve, while the other lever, through the shaft, is adapted to actuate t-he other fork, so as to move its sleeve. By wires, rods, or other suitable means 13 these levers 11 12 are adapted to be connected to a pattern mechanism, such as a patternchain, the., which moves them in one direction, gravity being 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 disposed a floating pulley 16, having a peripheral groove 17, which receives straps 1S and 19, extending, respectively, over and under the pulley and having their ends extending in opposite directions and secured tothe rods, as shown in Fig. 1. t
2O designates the box-rod lever, the same being in the present instance fulcrumed at a stationary point 21 on the loom side. One end of the lever has a slot 22, which receives a stud 23 at the center of the pulley, while its other end, it will be understood, is adapted to be connected in any suitable manner with the boxes.
The elements 14, et segua, aforementioned are claimed per se in my aforesaid application, Serial No. 85,306, and in combination with the call mechanism constituting the subject-matter of the present application they are claimed i'n a copending application, filed by me December 17, 1902, Serial No. 135,516.
The mechanism operates as follows: The shaft b being rotated continuously, through the parts m and n is transmitted to the rack g an alternating reciprocating and dwell movement. It will be observed that the stop-levers and stop-disks normally hold the callgears with their cut-out portions in the same horizontal plane, the arms a of the sleeves fc being received by said cut-out portions of the call-gears. The toothed segments of said arms are likewise normally held in the horizontal position. If a previous actuation of the fork S (9) has moved the corresponding sleeve a: so that the toothed segment which is next adjacent the rack g is thrown completely out of the plane of the call-gear, the reciprocation of the rack g will proceed idly with reference to the call-gear-z'- e., without turning it; but if the pattern so moves the fork through the connecting means'l3 that the said segment is by said .fork thrown back completely into the cut-out portion of the call-gear the rack will turn said call-gear through a half-revolution. The call-gear will not turn more than the half-revolution, because when one toothed segment was brought into the plane of the gear the other one was thrown out of said plane, thus producing a space corresponding to the other cut-out portion in said call-gear. Thereupon so long as the toothed segments are not again moved the rack will continue to reciprocate without effecting any further motion in the call-gear. In this way each rod 15 can be oscillated up and down with alternating dwells which are variable at will. It will be understood that the action of the pattern mechanism through the connecting means 13 and forks 8 and 9 in effecting the shifting of the toothed 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.
I have secured a very great advantage by having the segments 1 2 arranged on opposite sides of and close to a line drawn perpendicular to the axis of the sleeve By virtue of this arrangement the pattern from which the segments are controlled maybe made to shift the segments so that half of each is received by the corresponding cut-out portion of the call-gear. The object of this is to render it possible to make the boxes work pick-andpick with reference to any two boxes without having to resort to the pattern mechanism as an initial means for setting the two boxes i11- volved each time each comes into use--tl c., every alternate pick of the loom. Suppose, for instance, it is desired to work pick- andpick boxes 1 and 3. Both rods 15 being up, both sleeves are shifted until half of each of their segments is received by the cut-out portion of the corresponding call-gear. This position, it will be understood, is determined by some intermediate elevation of the pattern-chain or other form of call mechanism. The rack is then actuated, and the toothed outlines of the gears now being complete the rack turns the call-gears back and forth as it reciprocates, alternately lowering and raising both rods. Again, ifit is desired to work the boxes pick-and-pick between, say, box 1 and box 2 (the calling of box 2 corresponding to Irc the rod which is down is moved so that its,
two segments project half-way into the cutout portions ot' the call-gear, so as to complete the latters outline, whereupon the segment adjacent to the rack g for the other callgear having been moved out of the plane of said call-gear, and hence out ot' engagement with the rack, the call-gear for the rod which is down only will be operated. If it is desired to work the boxes pick-and-pick between boxes 2 and 3, itis accomplished `in the same manner as is accomplished the pick-and-pick movement between boxes 1 and 2, with the exception that at the start both rods are down.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is f 1. In a mechanism for shifting a part to either ofV two positions between intervals of varying lengths, the combination, with the part to be shifted, of a rotary pa rt operatively connected to said first-named part and having an endless way portions of which are movable to form recesses and a driving part adapted to engage said rotary part in the way thereof t drive the same, said movable portions being rotatable with the rotary part, movable as one, and being so arranged with reference to each other that when one is at one side of and close to one side line of the way of said rotary part the other will be on the other side of and close to said line, substantially as described.
2. In a mechanism for shifting a part to any of a plurality of positions between intervals of varying lengths, the combination, with the part to be shifted, of a rotary part operatively connected with said first-named part and having sections of its peripheral portion removed to form recesses, a driving part adapted to engage said peripheral portion of the rotary part to drive the same, and segmental devices rotatable with said rotary part, corresponding -to and alined with the recesses thereof, and

of said rotary part, substantially as described.
`said gear, lcorresponding to and alined with the recesses thereof, and movable as one axially thereof,l said devices being arranged one at each side of and contiguous to a plane perpendicular to the axis of saidgear, substantially as described.
4. The combination of a toothed portion removed to form recesses, each tooth next adjacent each eut-out portion 'of said gear being relatively short, a reciproeating rack adapted to engage and drive said rotary part, and an axially-movable part adapted to rotate with said gear and havingl .arms'projecting into the cut-out portions of :said gear, said arms carrying toothed segf ments arranged one at each side of and contiguous to a plane perpendicular to the axis of said part so that when the inner portion of one segment is received by the gear the inner portion of the other segment may also be re-` ceived by said gear and the toothed contour of said gear rendered complete, substantially as described. v
