FRICTION DEVICE FOR SHUTTLES.

Application filed January 10, 1913.

Specification of Letters Patent.

To all whom it may concern: I

Be it known that I, ISAAC SNow, a c1t1- zen of the United States, residing at Law: rence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Friction Devices for Shuttles, of which the following is a specification.

My invention relates to devlces 1n shuttles for the purpose of preventing thefilling from running out too freely and from floating. It is used so that the filling may as nearly as possible be kept straight at all times and without kinks. Its purpose is to produce a slight friction or drag on the filling as it is running out through the shuttle eye.

The advantages of my deviceare its durability and the uniform drag which it exerts on the filling. It also permits lumps and uneven places to pass through without breaking.

My device consists substantlally of a disk of rawhide or any other suitable material placed at an angle with the axis of the shut tle and held by suitable means so that the filling must pass under it or along its edge in its course to the shuttle eye, whereby the disk will crawl or move in a rotative mannor in a direction transverse to the move-. ment of the filling thus presenting a new surface continually to the filling. The disk which I prefer to use should be suitably confined in a osition transverse to or at an angle with t e axis of the shuttle and should rest upon a bottom plate in such a manner that the filling must pass between the disk and the plate. With such a disk, there is noregular rotative action, but the disk exei ts a drag on the filling which in turn causes the disk to creep, thus presenting a new point of contact continually. The edges of this disk should preferably be rounded and the disk may be made of rawhide, fiber, metal or even, glass. tact of the disk With the fi stantly changing, the filling cannot cut creases or grooves in the disk.

In the drawings, Figure 1 is a plan view of one form of my device in a shuttle. Fig.

. 2 is a sectional elevation from'the right on the lineX Y of Fig. 1.,

Fig. 3 is an elevation as from the right side of Fig. 2 of the device before being driven into theshut- As the point of conling is con-' tle.

tle. Fig. 4 is a similar view after its legs are driven into place in the shuttle. Fig. 5 is a side elevation of a modification of the holder which is screwed into place instead of being held in place by legs. Fig. 6 is a plan view of the well known suction eye shuttle with the form of my device shown in Fig. 5 in lace. Fig. 7 is a side elevation of a lea ed or weighted form of disk which I may use. Fig. 8 is a plan view of my device applied to a certain form of threading device in a shuttle. Fig. 9 is an elevation as from the left of the threader shown in Fig. 8 separate from the shuttle. Fig. 10 is a plan view of a well known form of self threading shuttle with my device attached.

Fig-11 is a sectional perspective of the same without the disk and Fig. 12 is a sectional perspective with the disk in place.

Inthe type of device shown in Figs. 1, 2, 3 and 4, A is the wooden part of the shuttle- B is the metal point thereof. C is the bobbin and D is the filling. H is a disk of'rawhide, fiber or any other suitable ma terial and is held in place by a holder such as L. In this form, the holder is stamped out of and bent from a single sheet of metal. It comprises a top plate 51 from which extends a bottom plate 50 in the form of a long 'curvedtongue which terminates at 54. Legs 52 and 53 are bent downward from top late 51 on each side of the bottom plate 50 01-111- ing the sides of the device so that the whole holder forms a loose inclosure for disk H.

shuttle is recessed to. fit holder L.

The legs 52 and 53 'serve the purpose of holding the device in place and are driven,

into holes 56 and 57 in the wood of the shut- These holes 56 and 57 preferably extend away from each other as they enter, whereby when the legs 52 and 53 are driven in, the holder L is firmly held in place. Disk H is thus held loosely between legs 52 and 53, top plate 51 and bottomv plate '50. .The holder L may be so placed that disk H will form an acute angle or a right angle with the ,filling'D as it passes from ion and moved so as to make it crawl more or less, it will never be out of contact with the filling long enough to permit the filling to float. It will thus cause a substantially .fixed drag on the filling.

As shown in Fig. 7, I may use a disk such as M loadedwith lead or otherheavy material as in order to increase the friction.

In Fig. 5 is showna modification of my device which has a back plate 81, a bottom plate 80 and instead of legs, the side supports 82 and 83 all suitably bent from one sheet of metal. A pin 85 passes through and is fixed in sides 82 and 83 and. passes loosely'through a large hole 86 in rawhide disk 87 thus holding it loosely in place. A screw 88 which passes through back plate 81 into the wood. P of the shuttle holds the device in place. l

In Figs. 8 and 9, I show the device in connection with a shuttle-threader or self threading shuttle of a design upon which I have applied for Letters Patent as threading device for shuttles, January 10, 1913, Serial No. 741,294. The threader F is preferably formed of a single sheet of metal and is inserted into a threader recess 21 adjoining the bobbin recess 20 in the wood N of the shuttle so shaped as to receive it. 22 is the groove in the wood through which the filling passes into the shuttle eye :23. The threader F at the bottom 30 is of semicylindrical form while the side walls 31 and 32 continue straight upward for a certain distance. An ear 33 is bent on one side and another ear 34 on the other side to rest in recesses 60 and 61 cut into the wood N on each side of the threader recess 21. Screws and 63 pass through suitable holes in each ear 33 and 34 into the wood N of theshuttle and hold threaider F in place. The top edge 35 of side '31 is so formed as to ust pass inside the depending tip 37 of a top guide plate 36 as shown in Fig. 9. The edge of top guide plate 36 nearest bobbin C has a long slope as shown in Fig. 8 while the far edge slopes slightly backward in line with'a vertical slot 24 in side 32. The slot 24 in the side 32 which when the parts are in place adjoins slot 25 in the wood of the shuttle connects with an eye in side 32 not shown which adjoins the shuttle eye 23 whenthe parts are in place. It will be seen that this device is itself-threading shuttle as by bringing filling D forward, it slips under nose 37 thence by bringing it backward it slips to the right along the front of plate 36'through slots 24 and 2.5 and lands in the eye of the threader which coincides with the eye 23 of the shuttle. Through the side wall 32 of threader F, I insert retaining side plates 40 and 41 for disk H which extend part way across threader F and are cutaway at the bottom as shown at 42 in Fig. 9 so thatthey form grooved bearings for the filling D. The top guide plate 36 extends over the top of plates 40 and 41 sufliciently to hold therein the disk of rawhide H which extends across the shuttle with its axis coinciding with the longitudinal axis thereof. Disk H is loosely held between bottom 30, sides 31 and 32, side plates 40 and 41 and top. guide plate 36.

In Figs. 10, 11, 12, I show the device attached to a well known form of self threading shuttle. The wood of the shuttle is shown at T and the metallic threader at M. In a recess 90 behind the threader M, I insert a holder which comprises a top plate 91, a bottom plate-92, a side plate 93 and a pin 94 which is driven into threader M passing loosely through a large hole in the disk 97 as shown.

In Fig. 6, the holder shown in Fig. 5 is shown in place in the well known suction shuttle. P represents the wood of the shuttle and R the shuttle eye while the holder is screwed in place to the side wall 89 as shown in Fig. 5.

The essence of my invention is the arrangement of a holder or inclosure through which the filling must pass into the shuttle eye with a confined mobile curved body such as a cylinder or disk made of suitable material with its axis substantially parallel with the course of the filling or the axis of the shuttle and so confined thatit has some freedom of action but will continually return by theforce of gravity to a position wherein it rests upon the filling and will continu ally or intermittently keep it incontact with the bottom of the holder.

may use a disk bored with a rela'tivel large hole and kept in place by means 0 a pin which passes through suchv hole.

What I claim as my invention and-desire to cover by Letters Patent, is:

1. In a tension device for shuttles, a disk located with its axis substantially parallel with the course of the filling and so confined as to be movable vertically but not Instead of being confined in an inclosure or. holder, I
