SPECIFICATION forming part of Letters Patent No. 787,653, dated April 18,1905.
Application filed June 30, 1903. Serial No. 163,727.
To all whom it may concern:
Be it known that I, J OSEPH B. WHITNEY, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Electrical Stop-Motion Mechanism for Textile Machinery; .and I do 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 accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.
This invention relates to mechanism adapted to automatically stoptextile machinery upon any irregularity in the action thereof; and it has reference particularly to such mechanism as applied to that portion of textile machinery which might be classified as that having to do with the drawing of threads or other filaments longitudinally, as in spinning, weaving, warping, &c.
It has heretofore been proposed to stop textile machinery when any irregularity occurs in the operation thereof by the use of electromagnetic mechanism. For instance, in weaving fallers or detectors have been arranged on the warp-threads in such manner that upon a break in any of the latter the corresponding faller or detector drops, closing a circuit whereby a magnet is actuated to move its, armature and through it' certain mechanical contrivances which either throw off the power from the loom or break it. In a copending application, filed August 9, 1902, Serial No.
119,114, I have disclosed an improved form such manner that while producing the minimum amount of abrasion on the threads they will promptly'respond to the action of gravity to close the circuit should any of the threads break, and in so far as acting as a contact device is concerned wires are especially desirable,because they ofi'er the minimum amount iii surface for the deposit of dust, lint, and the My present invention therefore has in view the employment of taut wires or the like for the pivotal supports for the detectors or fallers, as well as for the contact devices coacting with said detectors or fallers.
It also has in view to provide a simple, compact, readily-adjustable, and otherwise practical means for sustaining said wires.
In the accompanying drawings, Figure 1 is a top plan view of my invention. Fig. 2 is a side .view, and Fig. 3 is a vertical sectional view taken on the line w w in Fig. 1.
a, designates two plates or side frames, each having integral downwardly-projecting loops 6., which receive a horizontal rail 0, which may form a portion of the frame of the loom or other machine in which the mechanism is arranged, said loops afl'ording bearings for antifriction-rollers d, which take upon the top of the rails 0. e designates tie-bars, preferably three in number, whereby through the medium of clamping-nuts f, screwed on their ends, said plates 0; are secured in relatively fixed disposition parallel with each other. Assembled as shown in Fig. 1 parts a and 6 form a supporting structure or frame, which is adjustable on the rails c in the direction of the length thereof, set-screws g being provided in the loops to secure said frame in any desired position.
The upper corners of plates (4 are recessed for the reception of the trunnions h of rollersz', said trunnions being journaled on antifriction-bearings j, journaled in brackets 70, which are secured adjustably to the plates at by a slot-and-bolt connection Z.
Against the outer face of each plate a take horizonal bars on n. The bars are provided with openings 0 at regular intervals, those in the bar a being in staggered relation with reference to those of the bar m. Each bar is secured to the plate by bolts 1), the bolts for bars m penetrating vertical slots q in plates (0, while the bolts for the bar n penetrate hori- Zontal slots 1' in the plates. The bars are insulated from the plates by non-conducting sleeves s, surrounding each bolt 37 and penetrating the bar, and non-conducting washers t, interposed between the bar and the nut (or head, as the case may be) of the bolt on the one hand and the bar and the plate on the other hand.
a designates the fallers ordetectors. So far as the subject-matter of the present application is concerned it is only necessary to describe these tallers as being of the pivoted kind, the pivoting-point of each being by preference in proximity to but not quite at a point midway its length.
0) designates the wires which serve both as pivots for the fallers and as one set of contact devices with which said fallers coact to close the circuit, and 20 designates the Wires constituting the other set of contact devices. These wires are secured in the disposition illustrated in the drawings and under tension by means of plugs (a, which are inserted in the openings 0 in the bars and have longitudinal recesses 1 receiving the wires, each plug when the desired tension has been put on the wires being made to act against the wire as a clamp by means of a set-screw a, mounted in the respective bar and adapted to take against the plug. To accommodate the wires without their contacting with the plates, the latter are formed with openings 1, through which the wires extend. Inasmuch as the weight of fallers tends to depress wires 4), this effect is counteracted by the supporting means illustrated in Fig. 8, where 2 is a notched brace interposed between the sets of wires 4) and w and receiving in its notches 3 wires 2;, said brace being provided with integral legs 4, which have a slot-and-bolt connection 5 with a supporting-plate 6, mounted on tie-bars a, so as to be adjustable horizontally. Tie-bars e penetrate bosses 7 in plate 6, and one of these bosses may carry a set-screw 8, adapted to be set up against the corresponding tie-bar e to fix the plate 6 against lateral movement. An insulating-sleeve 9 and washer 10 are employed to electrically separate brace 2 from the plate 6 at the connections 5.
l1 and 12 designate the terminal portions of the circuit with which wires o and 2'0 are connected.
The threads (indicated at 13) are extended over rollers d and through the several fallers.
machine. My arrangement permits not only of adjusting each wire individually to the de-, sired tension, but includes means arranged in the supporting structure for adjusting the two sets of wires either vertically to and from each other or horizontally, so that by the manipulation of a comparatively few number of parts the whole set of fallers may be adjusted to a nicety relatively to the contactwires w and the threads 13, controlled.
Upon reference to Figs. 2 and 3 it will be seen that instead of each set of wires being arranged in a perfect plane they are arranged in parallel arcs of circles whose highest points approximate the innermost wires in each set. The reason for this is that since the fallers act by their weight to lift the threads higher at points remote from rollersz' than at points in proximity to said rollers it becomes necessary to correspondingly elevate the pivots of the fallers, as well as also the devices with which they drop into contact, so as to keep all the fallers at relatively the same angle.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a stop-motion mechanism for textile machinery, the combination of pivoted detectors or fallers, wires, each of said detectors or fallers being adapted to coact with said wires as acircuit-closer, and means for maintaining said wires under tension, substantially as described.
2. The combination of spaced supports, a pair of wires constituting contact devices, fallers pivoted on one of said wires and movable into engagement with the other wire, and means, adjustably mounted in said supports, for securing said wires under tension, substantially as described.
3. In a stop-motion mechanism for textile machinery, the combination of pivoted detectors or fallers, wires, each of said detectors or fallers being adapted to coact with said wires said wires under tension, substantially as de: i
scribed.
5. The combination of spaced supports, a
pair of wires constituting contact devices and penetrating said supports, fallers pivoted on one of said wires and movable into engagement with the other wire, and adjustable clamping means adapted to maintain said wires under tension and arranged against the relatively outer sides of said supports, substantially as described.
6. The combination of spaced supports, pairs of bars arranged against the relatively outer sides of said supports, sets of Wires penetrating said supports, means for clamping each set of Wires in one of the pairs of bars under tension, detectors or fallers pivoted on one set of Wires and engageable with the other set of wires, and means for adjustably securing said bars to the supports, substantially as described.
7. The combination of spaced supports, wires, means for securing said wires to the supports under tension, an auxiliary support for the wires disposed between and spaced from said first-named supports, and fallers or have hereunto set my hand this 26th day of.
June, 1903.
