SHUTTLE CHECKING AND RELIEVING MECHANISM FOR LOOMS.
SPECIFICATION forming part of Letters Patent No. 405,069, dated J' une 11, 1889. Application filed Mr y 24:, 1888, Serial No. 274,900. (No model.)
To all whom t may concern.'
Beit known that I, EDWARD M. BALL, a subject of the Queen of Great Britain, residing at South Berwick, in the county of York and State of Maine, have invented certain new and useful Improvements in Shuttle Checking and Relieving Mechanism for Looms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the l art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in shuttle checking and relieving` mechanism for looms and it consists of the novel combination and arrangement of devices, as wil-l be hereinafter fully described, and particularly pointed out in the claim.
In the accompanying drawings, Figures l and 2 are end views of so much of a loom as is necessary to an understanding of my invention, with the crankshaft thereof on the bottom and top centers, showing the parts of my invention in reversed positions. Fig. 3 is an elevation thereof, partly broken away, from the rear side of the lay, looking in the direction indicated by the arrow in Fig. l.
Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates the lay, B the rotary crank-shaft, Othe pitman connected at its ends with the lay and crank-shaft, D the swords upon which the lay is mounted, and E the shuttle-box having the pivoted swell e, all of which elements are common to looms of the ordinary well-known pattern.
My invention relates more especially to devices or contrivances which can be applied to ordinary looms at present in use without rearranging any of the parts thereof for autom atically pressing a binder-arm F against the swell of the shuttle-box when the crank of the rotary shaft B is on the bottom center, to press said arm F inwardly upon the shuttle simultaneously with the entrance thereof into the shuttle-box, and to automatically release said binder-arm and swell when the crankshaft is on the top center, as willbe hereinafter fully set forth.
Referring to Figs. l and 2, G designates a guide-pulley which is journaled on a stud or pin g, that is fixed to one of the swords D at an intermediate point of the length of the latter, so that said pulley is located below the lay, and around this pulley passes a rope, chain, or other like device H, one end of which is connected through intermediate devices, presently described, with the pitmanof the crank-shaft and the other end with the lower end of the coiled spring I. The other upper end of this spring is connected to a hook f, fixed to a rock-shaft F that is journaled on the swords, the binder-arm F being also fixed to the shaft and extending upwardly therefrom to bear at its free or unconfined end against the swell e of the shuttle-box. A lug or projection j is secured to or formed with the lay on the rear side thereof facing the crank-shaft, said lug lying at right angles to the lay and at a point thereon close to the pitman which connects the lay and crankshaft. A leverJ is pivoted to this lug or projection, and the pivotal bolt or pin passes through the lever at an intermediate point of its length, at the middle thereof or nearer one end, as may be preferred. One end of the lever is pivoted to the pitman C, as at j', at a point neail the pivotal connection between the pitman and crank-shaft. To the opposite or unattached end of the lever J is connected one end of the chain or cableH by means of a hook f; but it is obvious that this particular manner of connecting the chain or cable and the lever can be varied.
In operation the arm of the fulcrumed lever attached to the pitman is elevated when the crank is on the bottom center by reason of the pitman pulling the other arm of the lever down, as shown in Fig. 1, which causes the chain or cable to pass around the guidepulley and pull upon the spring to distend the same and turn the rock-shaft, thus causing the binder-arm to bear against the swell and press the latter inwardly simultaneously with the entrance of the shuttle in the shuttie-box. lVlien the crank is on the top eenter, the pitlnan elevates one arm 0'1"; the piv oted lever and depresses the other arm thereof, which thus relaxes the tension of the spring` on the roek-sliaft and releases the swell from pressure by the binding-arm.
My invention can be applied to any of the ordinary looms in use, preferably to that class lia-ving a protection-brake for preventing the crank-shaft from reversing.
Having' thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The ooinbinatioinwitli a crank-shaft, a lay, a pitlnan connecting the crank-shaft and lay, and a roek-sllaft Carrying a binder-arm, of a spring` connected to the rock-shaft, a `guidepulley journaled on one of the lay-swords below the spring, a lever fulerulned at an intermediate point of its length on the lay and pivoted at one end to the lay-pitn1an at a point in juxtaposition to the pivot-connection of said lay-pitnian to the crank-shaft, and a eliain passing around the `guide-pulley and oonneeted at its ends to the other end of said 1ever and the spring, substantially as and for the purpose described.
In testimony whereof I affix my signature in presence of two Witnesses.
