SPOOL HOLDER FOR 'SEW'ING MACHINES.

Application filed June 10, 1925. Serial-No. 36,244.

To all whom itwmy concern:

Be it-lniowntha-t I, Anion-LAM Snnns'r, a subject of the King of Great Britain, and residing at the ci-tyof Montreal, in the Province of Quebec, in the Dominion of Canada, have invented a certain new and useful Spool Holder for Sewing lifachines, of which the following is the specification.

The invention relates toaspool holder for sewing machines, as described in the present specification and illustratedin the accompanying drawings that form part of the same.

The invention consists essentially'of the novel features of construction pointed out broadly andspecitically in the claims for novelty followinga description containing an explanation indetail of an acceptable formiof the invention.-

Theobjects ofthe invention. are to avoid losses through unauthorized persons removing the spools from their holder; to eliminate'the'theft of spools containing silk or cotton threads in factories and such places and thereby cancel a yearly. charge on the mainifacturers; to furnish a spool holder that will facilitate the work of the operator by'keeping many varieties'of spools in a position to be immediately used and at the same time have them safely secured to their respective places under one lockingv means; to supply a holder readily installed either toth'e sewing machine .base or to. a bench near by and be within reach at all times and so arranged that in the threading the machine will not be in the way of the sewing operation; and generally to provide a device at a comparatively low cost to the manufacturer of clothing without diminishing its efliciency or its durability.

In the drawings Figure 1 is a perspective view of the spool holder.

Figure 2 is a vertical sectional view of the holder illustrated in Figure 1.

Figure 3 is a perspective view of the spool holder for cotton or like spools only.

Figure 4 is a vertical sectional view of the holder illustrated in Figure 3.

Figure 5 is a plan view of the revolving head without the cover plate.

Figure 6 is a plan view of the fixed head in the form of the invention.

Figure 7 is an enlarged perspective detail of the thread guide in the revolving head, showing its fastening.

Figure 8 is an enlarged perspectire detail ofv the thread guide in the fined head.

' Like numerals of reference indicate correspondingparts in the various figures.

Referring to the drawings, the post extends upwardly from the base 21, the latter having screw holes 22, through which it is attached to the table or bench.

The baseoap at} is simply arrangedon the post 20, and covers inthe base 21, so that the screw heads of the screws used to secure the base 21 to the table or bench are covered in-so as to avoid any of the thread catching theppon and breaking.

fice 24 therethrough for the hasp, of the look 25, intern'iediate of its height, the rigid key 26 projects outwardly from the base to support and engage the Thead 27 which is slotted at 28 to receive said key, this T- head 27 being slidably arranged on the post above the key 26.

The T-head or erossarm 27 is preferably in channel form, having the flaring ends 29 and 30 and the channel bed inwardly recessed from the ends at 31 and 32 to-form free passages for the thread guides '33 and 34 which are of wire and rigidly secured to the channel bed and projecting ,outwardly therefrom into said recesses 31 and 32 and curled at. their outer : ends 35 and 36 indouble coils with the extremities 37 and 38 projecting beyond the. coils in anoutward direction.

The cross arm 39 is rigidly secured to the post 20 towards the lower end thereof and is parallel to the T-head 27 and directly under said T-head the spool spindles 40 and ne post 20 at the upper end has an ori- 41 project upwardly from the disks 42 and 48 rigidly secured to the outer end of the cross arm 39, said spindles extending in an upwardly direction for a sufficient distance to avoid anypossibility of lifting spools therefrom without coming into contact with the T-head 27, the function of which is to lock the spools on the spindles.

The revolving head 44 is slidably mounted on the post 20 above the T-head 27 and the v hub 45' of this revolving head meets the hub 46 of the fixed head 27 and turns thereon.

The revolving head 44 is in the form of a circular plate extending from the hub 45 and downwardly flanged at the edge 47, and from this edge the thread guides 48 of simi lar shape to the thread guides 33 and 84 are rigidly secured on the upwardly projecting arms of the brackets 4:9, said brackets 49 extend around and against the flange 4t? and are secured to the circular head at by the splayed ends of the spindles 50 projecting through said head thereby maintaining the thread guides 40 in perfect alignment with the centres of the spools 51 mounted on said spindles 50 and rotatable thereon.

The cover 52 is also in the form of a circular plate and extends from the hub 53 slidably mounted on the post 20 and cover ing the upper ends of the spindles 50, said post 20 extending upwardly beyond the cover 52 to clear the orifice 24: for the hasp of the lock 25.

In Figures 3, 4t and 6 the revolving head has been omitted and the post shortened. In these figures the post Jet is formed with an orifice 55 immediately above the lixed head 56, this fixed head being in the form of double cross arms 57 engaging a key 58, while parallel double cross arms 55) are rigidly secured to the post 5 towards the base (50, said cross arms 59 carrying the spool disks 61 and spindles (S2, otherwise the construction is the same as already described, and of course it must be understood that the double cross arm construction may be applied to a form of the invention illustrated with the revolving head.

In the operation of this invention the spool holder is rigidly secured to a table or bench by bolts or screws in a convenient position to the sewing machine and the threads from the spools on the revolving heads are brought out through the revolving guides, usually one at a time.

The revolving head rotates freely, therefore the pull of the thread will be directly from the sewing machine to the spindle nearest to said sewing machine.

The silk spools of various colors are supposed to be held on the revolving head, while the cotton spools are supposed to be held on the fixed spindles under the lined head, and the threads from these cotton spools are drawn through the thread guides projecting from the ends of said fixed head, consequent- 1y there will practically be no obstruction for the drawing of the threads from either rotating head or fixed head and the machine will serve the purpose of keeping all the spools secure on their spindles until removed and replaced by an authorized person.

lVhat I claim is 1. In a spool holder, a rotating head coi1- taining spool spindles and thread guides and encircling a vertical post secured to a base, lower and upper cross ari'ns secured to said vertical post, the former having spool spindles extending therefrom and the latter forming a base member for said-rotating head, a cover for said rotating head encircling said post, and a lock adapted to be insorted and locked through an orifice in said vertical post and above said cover.

2. In a spool holder, a rotating head containing spool spindles and thread guides and encircling a vertical post secured to a base, lower and upper cross arms secured to said vertical post, the former having a disk at either end and spool spindles projecting therefrom and the latter having a channel bed forming a free passage for thread guides at either end, said upper cross arm forming a locking means for said lower spindle spools and a base member for said rotating head, a cover for said rotating head encircling said post, and a lock adapted to be inserted and locked through an orifice in said vertical post above said cover.

Signed at Montreal, Canada, this 29th day of May 1925.

ABRAHAM SELBST.
