SPECIFICATION forming part of Letters Patent No. 792,957, dated June 20, 1905.

Application filed February 4, 1905. serial No. 244,205.

To all whom it may concern:

Be it known that we, JOSEPH APPLEBY and EDWIN APPLEBY,subjeets of the King of Great Britain, residing at 4:5 Tower road, Aston, in the county of Warwick, England, have invented new and useful Improvements Relating to Cotton Spinning and Like Machinery, of which the following is a specification.

This invention relates to machinery for cotton spinning and twisting and for like purposes, and has for its object to provide for the more ready and eifective adjustment and setting or fixing of the thread-guides or guides and snarl-catchers employed with such machinery.

Our invention comprises the combination, with metallic thread-board flaps or holders for the guides or guides and snarl-catchers, of self-locking or snap-fastening devices, permitting of very ready and accurate adjustment and setting of the said guides and snarl-catchers; also, an improved construction of such holders and the arrangement of the same in independent attachment with the thread-board rail or other part of the machine with which they are to be employed.

Referring to the two accompanying sheets of explanatory drawings, Figure l is an illustration of a steel or other metal blank for the formation of one type of the front or movable hinged portion of one of our threadboard flaps or supports or holders for the thread'guides or guides and snarl-catchers. Fig. 2 is a plan, Fig. 3 a side View, and Fig. 1 an inverted plan, of the said blank when pressed or formed to the required shape or configuration. Fig. 5 is an illustration of a steel or other metal blank for the formation of one type of the back or fixed hinged portion of one of our thread-board flaps. Fig. 6 is a plan, Fig. 7 an inverted plan, and Fig. 8 an end view, of the said blank when pressed or formed to the required shape or configuration. Fig. 9 is an illustration of a steel or other metal blank for the formation of'one type of lever-grip or snap-fastening for our thread-board flaps. Fig. 10 is a plan, and Fig. 11 a side view, of the lever grip or snap formed from the said blank. Fig. 12 is an illustration of a steel or other metal blank for the formation of one type of friction or grip plate for use with our thread-board. Fig. 13 is a plan, and Fig. 1A a front view, of the friction or grip plate formed from the said blank. Fig. 15 is a plan, and Fig. 16 a side view, of our complete thread board flap with combined guide and snarl-catcher in position for service and secured upon a metal strip for attachment to the rail or like part of the machine. Fig. 17 is a view showing the front hinged portion of the flap or support or holder with the guide and snarl-catcher secured thereto thrown back to its out-of-service position. Fig. 18 is a plan, and Fig. 19 aside view, of what is known as a pot-eye type of guide as adapted for use when required with our threadboard flaps or supports or holders in place of a combined guide and snarl-catcher,as aforesaid. Fig. 20 is a side view, and Fig. 21 a plan, of a support or holder with the front and back portions formed from the one piece or blank of metal and fitted with our self-locking or snap-fastening device for holding a thread.- guide without snarl-catcher. Fig. 22 is a side view of a simplified form of our hinged thread-board flap, in which the lever, grip, or snap acts directly upon the shank of the guide and snarl-catcher, or without the intervention of either a spring piece or a friction or grip plate. Fig. 23 is a plan showing the hinging of the front and back portions of the threadboard flap and the provision of abutmentstops on the joint. Fig. 24 is a plan of the front portion alone. Fig. 25 is a plan of a sheet-steel spring which is sometimes employed instead of the grip-plate shown by Figs. 12 to 1 k.

- The same reference-letters in the different views indicate the same or similar parts.

In the application of our invention as in the example shown by Figs. 1 to 17 inclusive, we make each thread-board flap or hinged support or'holder for a thread-guide and.

finished shape or configuration indicated. The bent-up ears or lugs 0 serve as bearings or supports for a rivet or pin 03, on which is mounted the lever-like grip-piece or snap a for securing the combinedguide and snarlcatcher a in any position within its range of adjustment. The back portion f of each thread-board flap or guide holder, made from a blank such as is shown at Fig. 5, has the aforesaid front portion hinged thereto, as is clearly indicated at Figs. 15, 16, and 17. For the attachment of the desired number of thread-board flaps to the thread-board rail or like part of the cotton-spinning or similar machine we sometimes employ a metal strip, such as g, and secure the back portions, such as f, of the thread-board flaps to the said strip by means of ears or lugs, as It, projecting from the back portion f, and which engage or are riveted or fitted tightly within corresponding holes or apertures in the strip. The strip g, having the thread-board flaps fixed thereto, as aforesaid, is secured to the rail or like part of the machine by screws inserted through apertures, as 2'. The projections or the like may be formed upon the strip and the corresponding holes or apertures within the thread-board back plates or portions f. With a strip, as 9, we greatly facilitate the secure fixing of the respective thread-board flaps or guide-holders in position to the required gage to suit any frame or machine while providing for the ready detachment of any one of them. When the grip-lever or snap e is I in the position shown by dotted lines at Fig. 16, the guide and snarl-catcher a can be pushed in or drawn out to any position within the limits fixed by the length of its shank or stem part, or it may be entirely withdrawn, if desired; but when the grip-lever is pulled or pressed up to the full-line position in the said figure the guide a is securely held in the desired position.

To permit of the adjustment of the guide or the combined guide and snarl-catcher in both longitudinal and transverse directions, we interpose between the lever grip or snap e and the inner surface of the front portionb of the holder a friction or'grip plate, as j, which on the release of the snap by depressing it to the dotted-line position (shown at Fig. 16) is free to slide between the ears or bearing-pieces 0 upon the lever pivot-pin 61. The said friction or grip plate j is suitably shaped, as shown at Figs. 13 and 1 1, for engaging the pivot-pin d and to embrace the shank of the guide a. A flat seating, such as is, is also provided to receive the thrust or pressure imposed by the cam-like projection Z of the lever grip 0r snap 6 when the latter is closed. The friction or grip plate j, shaped as described and as illustrated, can be readily made to slide between the ears 0 of the part b after the release of the lever-grip e for accu rate lateral adjustment; but any twisting or circular movement, such as would throw the guide out of adjustment, is effectually prevented. Longitudinal adjustment is obtained by drawing out or pushing in the guide, as aforesaid.

The front hinged portion Z) of the threadboard flap or guide-holder can be prevented in various ways from dropping when in its service position below a right angle with the back portion f. In the example shown by the Figs. 1 to 17 such result is attained by the formation of an abutment m on the back plate or portion f. The grip-lever 6 can also be readily made to serve the same purpose and in addition to serve as a stiffener or strut for the front portion Z). I

Each thread-board flap or guide-holder has its own independent hinge-joint pin and is thus complete in itself and may be removed and replaced without disturbance of any of the others employed with it.

In the example shown at Figs. 20 and 21 our gripping or snap devices, including the lever e and a friction-plate j, as aforesaid, are fitted upon a holder made from a single plate instead of from a pair of hinged plates or parts as aforesaid.

Instead of employing a friction-plate, such as we sometimes interpose a sheet-steel spring, such as shown at Fig. 25, between the lever-grip e and the inner surface of the front part bof the holder. We sometimes also dispense with both of such elements (the frictionplate and the spring) and cause the lever grip or snap to act directly upon the shank of the guide a, as in the example illustrated by Figs. 22-, 23, and 24. The said figures also illustrate the employment of abutting portions, such as it, in the hinge-joint to prevent the front plate or part I) from dropping when in service below a right angle with the back plate or part f.

The shanks of the guides or combined guides and snarl-catchers a, also of the pot-eye type of guides, as illustrated at Figs. 18 and 19, may be of a D shape or provided with a flat and serrated surface for abutting upon the inner surface of the front part Z) of the holder. When dispensing with the use of a friction plate, as f, or a spring, such as shown at Fig. 25, between the lever-grip e and the under surface of the front part b of the holder, we preferably provide a semicircular seating, as 0, in the front part I) and indent or serrate the same to provide an effectual grippingsurface. In this case the rounded or circular portion of the guide-shank fits within or upon the seating, while the fiat portion is next the lever-grip. The shank is preferably threaded along its circular portion to correspond with the aforesaid indents orserrations of the seatmg.

In thread-board flaps or guide-holders of the type shown by Figs. 22 to 24 lateral or transverse adjustment is arranged for by making the screw-holes, as p, for the direct attachment of the flap to the rail or like part of the machine of an elongated form, as illus trated. With the screws slackened transverse adjustment may then be readily effected. With this thread-board flap the aforesaid metal strip 9 is not employed. The same method of attachment and means for obtaining transverse adjustment may be used with the thread-board flaps, such as illustrated in thelother figures, the strip g being dispensed Wit 1.

The pot-eye type of guides a (illustrated at Figs. 18 and 19) are made from flat steel strips pressed or formed to the shape shown and with spring-like jaws at one end for gripping the pot or porcelain eye q.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
