To all whom it may concern: I

Be it known that, I, Lnwrs .T. 'HoUGHroN,

a citizen of the United States, residing at Worcester, in the county of Worcester and- State of Massachusetts, have invented a new and useful J ack-Spool, ofwhich the following is a specification. V

This invention relates especiallyto the large spools employed in mills, which are respoo ferred to as j ackspools.

The object of his inventionis to provide'a strong, simple, and efiicient spool in which the spool-heads are fastened to the body of the spool in such way as not to become loose and shackly. i

To this end this invention consists ofthe spoolas an article of manufacture and ofthe combinations of parts therein, as hereinafter described, and'more particularly pointed outin the claims at theend of this specification.

Inthe accompanying drawings, Figure 1 is a fragmentary view, partly in section, of sufficient parts of a spool to illustrate the application of this invention thereto; Fi 2 1s a detail view of an end trunnion or stud. Fig. 3 is a detail view of the locking-washer. Fig. 4 is a fragmentary view of one end of the spool-body, and Fi 5 is a detail view of a modified forni of locIring-washer.

A jack spool of the type to which this invention relates consists of a cylinder -or body with a spool-head at each end thereof.

In this class of 'sfpools a variety of fastening devices are usedor fastening the spool-heads inplace. In this class of s ools as ordinarily constructed the spool head or disks are usually simply butted against the end of a wooden cylinder or body portion. The spools themselves are com aratively large and hea and when woun with considerable Wei tsof yarn are subjected to rough usa e. le, when a spool of this or exanfip kin ,either when led or empty, is permitted to .fall a concussion will be im arted to the spool head, or disk. In the or ary type of a spool of this kind the blows or concussions upon the spool-heads are transmitteddirectl to the stud or center sv indleof the This causes a direct s earing pressure on the studs or spindles of the spools which causes the s col-heads to become loose'and shackly. a spool constructed according; to this invention I provide for strengthening the joints between the body portion of the spool and the spool-heads by providing-the body of the spool with a proeflicient center fastenin this invention as shown in ordinar .gudgeonbolts.

sponding sockets, and I have combined the jection at each end, which fits "into correparts as thus put together withasimple and I I which cannot becoine loosened'or turne from locked position. By providin the body of the spool with projections W 'ch fit into recesses mthe spool-heads all blows or concussions on the spool-heads insteadof bein transmitted directly 'to'the center studs be transmit-. ,ted to thelarger and l'ess'easily injured pro-v jectingendof the spool-body.

Referring to the accompanying drawings for a detail description of as 001 embodying nut-socket 11 and with the longitudinal spindle-hole- 12 opening therefrom to the end of the spool.

The sheet-metal spool-head 13 is provided ig. 1, 10 desigwith a eripheral flange or head 14 and with i a punc ed-out socket or de ression 15 for recelving the projecting en 16 of the body. This forms, in efiect,"a dowel-joint of large diameter between the body portion and spoolhead which will render the spool-head absolutely rigid so long as the same is held in place from being pulled ofl of the end of the s 00 I To fasten the spool-headin place against endwise displacement, Ima use may of the Iii the rawings I have i lustrated a construction in which the dgeon-bolt 17 is threadedjatits inner end into the nut29, and mounted on the gudgeonbolt 17 is a washer 2 1. If desired, the washer 21 may be made with the gudgeon-bolt itself or may be threaded onto or otherwise fas- ,ten ed thereto. trated the gudgeon-bolt 17 is provided with a In the construction illusshoulder 18, having keys or wings 19, which fit in ways 22 of the washer. Toprevent the dgeon-bolt from unscrewing, I preferably, iit not necessarily, employ astenin studs or nails, which are driven through soc ets '23 of the washer. In some cases instead of using sockets inthe form of notches, as shown in Fi 3, the washer'may have holes, as shown in ig. 5. I o

In practice I preferably make the lockmgwasher 21 -of substantially the same size as loo the projectin end of the s col-head, and I have found t 's to be of a vanta e in prac-' tice, as this reinforces the entire ace of the punched-out part of the spoolhead, so that when the sheet-metal spool-head is clamped in place the center part of the spool-head will be clamped or held so that it cannot be bent while the outer periphery of the s 001- head being protected by its flange l4 wil also be sufficiently stiff so that the spool-head cannot be easily jammed or be'nt sidewise.

In assembling a jack-spool constructed according to this invention the center stud is screwed in by using a spanner or special wrench for turning the locking-washer, and when the spool-head is tightly seated the locking-washer is fastened by nails or screws,

so that there is no possibility of the parts becomingloose and shackly- I am aware that changes may be made in the shapes and proportions of parts of a spool-head without departing from the scope of my invention as expressed in the claims. .I do not wish, therefore, to be limited to the particular construction I have herein shown Letters Patentof' the United States, is

and described; but

What I do claim, and desire to secure by 1. As an article of manufacture, a jack' spool comprising a solid body portion having a cylindrically-reduced end surrounded by a square shoulder, a sheet-metal ,disk-shaped spool-head having a square-shouldered stamped-out socket receiving said reduced "end of the body portion to -secure the head from sidewise displacement ,the head resting on the shoulder, and a gudgeon-bolt for fastening the shoulder against endwise displacement. 2.
