ELECTRIC STOJP-MOTION DEVICE FOR'LOOMS.
Specification otLetters Patent.
I Application filed June 18, 1&18. Serial No. 305,004.
To all whom it may concern:
Be it, known that I, lVAsYL LAWRUSHKO, residing at Bridgeport, in the county of Fairfield and State of Con necticut, have invented certain new and use ful Improvements Devices for Looms, of which the following is a specification.
The primary object of the present invention is to provide an electric. stop motion device for looms wherein an electric circuit is adapted to be established for stopping the loom when the fabric passing therethrough is not traveling in the proper manner.
A further object of the invention is to provide an electric stop motion device for looms that cooperates with the fabric therethrough to guide the sameduring its movement and which is adapted to be oper ated upon a reverse movement thereof to complete an electric circuit and stop the operation of the loom.
the invention consists in the combination and arrangement of parts herein fully described in connection with the accompanying drawings and in which like characters of reference indicate similar parts throughout the several views.
In the drawings,
Figure 1 is a longitudinal sectional view of the guide roller constructed in accordance with the present invention and embodying mechanism for completing an electric circuit, v
Figs. 2 to 13 are cross sectional views taken on corresponding section lines on Fig. 1 showing the several elements forming the guideroller,
Fig. 14; is a detached side elevational view of the tubular screw,
a diagrammatic view showing the split fabric passing through the loom over the feed and guide rollers in its proper movement, and
Fig. 16 is a diagrammatic view, similar to Fig. 15 with the feeding roller improperly engaging the fabric thread through the loom and causing a reverse movement of the guide rollers as illustrated for purposes of stopping the loom.
In the art to which this invention pertains, with particular reference to the manufacture of velvet and like fabric, there is employed a feed roller having a plurality of in Electric Stop-Motion and carried beyond ing the feed rolleras illustrated in Fig. 16
purposes of .for th v sitating the severing of the other ply thereof so that additional time is necessary for passing initial passage of the.-
. .One of the With the above and other objects in view,
. plurality I surface of the fabric to insure a movement thereof in the reverse direction as indicated Fig.
The present inventhis defect by assomechanism with of the fabric the guide roller pr0- the loom, it being understood that the present Windingmechanism is associated with a. machine for manufacturing velvet or any similar material of two ply construction adapted for transverse severing, there being provided as illustrated, a pair of feed rollers I 1 provided on their peripheries with a plurality of pins fabric strips 3 that are separated by the knife 4 as illustrated in said figures. The fabric 3 'in passing to the receiving rollers 5, and upon leaving the feed roller 1 overguide rollers 6 and 7, the fabric 3, being held in engagement 1 with the guide auxiliary rollers 7 and during the proper movement of the fabric 2 for engagementwith the pass ' through the receiving mechanism, the guide ent invention particularly roller 7 moves in the direction indicated by the arrow in Fig; 15. The gist of the pres resides in the specific construction of the guide roller 7 which will now be described in detail.
The guide roller 7 is shown in detail in Figs. 1 to 14 and includes a hollow cylindrical casing 8 open at each end and provided upon the periphery thereof wit-h a plurality of pins 9 arranged thereon in any desired formation. One end of the casing 8 is closed by a plug 10 secured in said end by a set screw 11 illustrated in Fig. 2 while an opening is provided centrall thereof to receive the stub axle 12 carried y the .block 13 and upon which axle, the plug 10 and easing 8 are rotatably mounted, lateral movement of the plug. and easing upon the axle 12' being prevented bythe ring adjustably secured to said axle between the block 13 and plug 10.
As illustrated .in 'Fig. 3, the inner wall of the casing 8' is uninterrupted and is adapted to receive in the open end thereof, the cylinder 15 that is retained therein and held immovable relative to said casing by p a set screw 16 shown at the right hand side of the casing'8.
Diametrically opposite key-way slots 17 are formed upon the inner face of the cylinder 15 as shown in Figs. 1 and- 5 for purposes presently to appear.
. A block 18, is secured in the left hand end of the cylinder 15 by aset screw 19 illustrated in said figures and forms a bearing for one end of an expansion coil spring 20 contained within said cylinder. A cupshaped member 21 has the end wall 22 there- :of engaging the other end of said coil spring 20 and is slidably received in the cylinder 15, being capable of free longitudinal movement and prevented from relative rotary movement by the keys 23 formed upon diametrically opposite sides of the periphery thereof and extending longitudinally for sliding reception in key-way slots cup 21 with lugs 27 shown 17 of the cylinder.
With this construction, it will be seen that the cup 21 is capable of sliding movement in the cylinder and guided in such .movement by the keys 23 engaging the slots 17 which will prevent rotary movement of said cup and cause the same tobe revolved with the cylinder 15 and easing 8.
A tubular screw 24 shown in Figs. 1 and 14 includes a plain body portion as illustrated with an annular flange 25 intermediate the ends thereoinnd with a threaded head 26 at its forward end, the tubular screw 24 being adapted to have its head 26 inseged in the hollow portion of the 1n Figs. 1 and 7 projectingfrom opposite sides of the inner face of said cup for reception in the grooves of said screw head while the end of the provided with a pair of of the tubular screw 24 is received as shown in. Figs. 1 and 11, the screw being secured immovable relative to said support by the set screws 33.
An insulating bushing 34' of tubular for mation extends into the tubular screw 24 and terminates at a point adjacent the screw head thereof, the rear end of said insulating bushing projecting outwardly of said screw and having an offset portion 35 for the reception of a threaded. terminal plug 36. A short metal tube 37 is inserted in the outwardly projecting end of the bushing 34 and is; engaged by the terminal screw 36.- A contactneedle 38 slidably projects through said insulator bushing 34 and i:- collars 39 and 40, an expansion coil spring 41 surrounding said contact needle 38 between the metal tube 3 7 and collar 40 while a closure plug 42 is inserted in the inner end of the insu lator bushing 34 to be engaged by the collar 39 to limit the forward movement of the contact needle caused by the spring. A bracket 43 is carried by the attaching plate 30 and supports a terminal plug while circuit wires 45 are connected to the termi-- nal plugs, 36 and 44 forming the lines 0? the circuit- The journal bearings for the casin -8 and parts that rotate therewith include the stub axle 12 at the left hand end thereof and the tubular screw 24, it being noted that the gasket bearing 28 rotates with the cylinder and easing 8 while the tubular screw 24 remains stationary by being secured by the set screw 33 to the stationary bracket 31.
During the operation of the device, as-
the cup during such movement is cushioned by the spring 20 and maintained forwardly: positioned by said screw and the sprin 4:6 surrounding'the screw between the bloc 28 and open end of said cup, the circuit in this position of the parts being open.
the outer face of'. said cup slide in the cylinder roov-s 17 and Should the fabric strips 3 improperly engage the feed rollers l as illustrated in Fig. 16 as by being-retained by the pins upon the peripheries of the cylinders and, wound upon said cylinders as illustrated, guide rollers 7 will be reversely rotated 'as indi cated by the arrow in Fig. 16 and during this movement, the cup 21 rotating with.
l'Vhile I have herein shown what are be lieved to be the preferred embodiments of my invention, it is nevertheless to be understood that minor changes may be made in the form. combination and arrangement of parts without departing from the spirit and scope of the invention as claimed.
