FILLING-REPLENISHING LOOM.

Specification of Letters Patent Patented May 25, 1915.

To all whom it may concern:

Be it known that I, THELESTHARE MAR- TIN, a subject of the King of Great Britain,

residing at Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to a means for preventing the operation of the filling replenishing mechanism in an automatic loom upon the failure of the filling feeder properly to position a filling carrier for transfer after the indication of entire or partial exhaustion in the running shuttle and the object is to provide a simple and efficient means for securing this result, particularly by or through making the usual guiding abutment movable and utilizing this movement to effect the result desired.

The nature of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

The drawings show so much of an ordinary automatic filling replenishing loom together with the parts constituting a preferred form of this invention as is necessary to an understandmg of the 1nvent1on.

In the drawlngs, Figure 1 1s a rlght hand side elevation and partial transverse section of a sufficient portion of an automatic filling replenishing loom of the Northrop type with the parts involved in this invention applied I thereto; Fig. 2 is a similar view of some of the parts shown in Fig. 1 showing a filling carrier in proper position for transfer.

The construction of loom illustrated and to which a preferred form of the invention is shown as applied is of the type illustrated and described more at length in the patent to Stimpson and Southwick No. 823,644 granted June 19, 1906, and in view thereof, and of the well known character of the Northrop loom it will be unnecessary to here position the spare filling carriers.

describe anything more than those parts directly concerned with the present invention.

The breast beam of the loom is indicated at 1 and has fixedly mounted thereon the usual filling feeder which comprises two connected disks or plates to receive, hold and One of these disks or plates is shown at 3 mounted on the stud 40 projecting from the hopper stand 2.

The filling carriers or bobbins 4: are as usual held by their butts and tips by and between the two disks of the hopper or feeder 1n a circularly arranged series, the seats for the butts being shown at 5 in the disk 3. The filling carriers are brought one by one into position for transfer from the hopper or feeder to the running shuttle by a suitable mechanism which in the construction illustrated is shown as comprising a ratchet or toothed disk 6 secured to and rotating with the hopper, there being one tooth for each filling carrier. A feed pawl 7 co6perates with the ratchet 6 to give the step by step feeding movement to the hopper and the detent pawl 8' acts to prevent retrograde movement, all as more fully set forth in the said Stimpson and Southwick patent.

The filling replenishing mechanism also comprises a transferrer 9 pivotally mounted at 10 on the hopper stand and operating when depressed or moved downward to transfer a filling carrier from the hopper to the shuttle. A notched dog 11 is pivoted at 12 to the depending arm of the transferrer and upon the call for filling replenishment is swung upwardly into the path of a bunter carried by the lay all in a manner known and familiar in this typecf automatic filling replenishing looms.

As fully explained in the patent to F. G. and J. H. Cobb No. 780,266, January 17 1905, should the hopper or feeder fail properly to present a filling carrier in accurate position for transfer the transferrer upon the next operation of the replenishing mechanism would improperly engage the filling carrier and injure it or some of the adjacent mechanism. This undesirable result is prevented by the present invention.

It has been common heretofore to provide a fixed abutment secured to and projecting from the hopper stand with its vertical face in, such position as to act as a guide for one side of the filling carrier during transfer. In the present made movable and is utilized through suitable conneotions to prevent transfer taking place except and until the filling carrier is properly positioned for transfer.

The hopper stand is shown as provided invention this abutment is with guiding lugs 13 and 14. The movable abutment 15 is provided with 'a shank 16 sliding in the guiding lugs 13 and 14. A spring 17 acts to throw the abutment to the right, viewing Fig.1, and its movement to the left is limited by the stop 18 thereon contacting with a fixed portion of the hopper stand.

The shank of the abutment carries at its end pivoted thereto and depending therefrom a latch 19, and a light leaf spring 20 holds the latch in vertical position as shown in Fig. 1. The dog 11 has adjustably mounted thereon a lug 21 which when beneath the end of the latch 19 holds the dog 11 down out of the path of the bunter on the lay, and consequently prevents the operation of the transferrer. The lug 21 is so adjusted with respect to the 1atch'19 that the latch will not pass off the lug until the abutment 15 has moved to such a position to the leftas is necessary properly to guide a filling carrier during transfer, or in other words, until the filling carrier has been properly positioned by the feeder. The spring 20 enables the latch 19 to yield to the left if struck by the lug 21 during the oper ation of the transferrer or upon the movement of the abutment 15 to the right as the filling carrier passes to the shuttle.

The feeder in its operation when it fails properly to position the filling carrier generally fails by reason of not bringing the filling carrier far enough along in its rotation, hence the abutment will not be moved to such a position as to release the dog 11. If the failure properly to position the filling carrier is caused for any reason by the overrunning of the feeder the abutment will be limited in its movement on the contact of the filling carrier therewith by the engagement of the stop 18 with the hopper stand and mis-position in this direction of the filling carrier will thus be prevented.

In Fig. 2 a filling carrier 4: is shown as having been brought by the filling feeder into proper position to transfer. In this position the filling carrier has contacted with the abutment 15, forced it back to the left, caused the latch 13 to ride over the lug 21 and allowed the dog 11 to rise into position to be struck by the bunter on the lay.

The filling carrier will now be properly guided by the abutment into the exhausted shuttle.

It will thus be seen that the operation of the replenishing mechanism is prevented by this invention upon failure of the feeder properly to position a filling carrier,'and that this is secured by failure of the movable abutment to reach guiding position or to prevent the operation of said mechanism upon failure of the feeder to-position prop- I erly a filling carrier and thus move the abutment into proper guiding position.

2. In a loom, automatic filling replenishing mechanism including an intermittingly' movable feeder to contain a series of filling carriers, a transferrer to transfer a filllng carrier therefrom, controlling means for said transferrer including a dog pivoted thereon and movable into position to be struck by a bunter on the laywhen the:

operation of said mechanism is called for,a yieldingly projected slidably mounted abutment movable by the filling carrier into position to guide the filling carrier when transferred, a lug carried by said dog, a yielding latch carried by the abutment and cooperating with said lug to hold the dog out of operative position until the abutment has been slid into a position properly to guide the filling carrier when transferred.

3. In a loom, automatic filling replenishing mechanism including an intermittingly movable feeder to contain a series of filling carriers, a transferrer to transfer a filling carrier therefrom, controlling means for said transferrer including a dog pivoted thereon and movable into position to be struck by a bunter on the lay when the operation of said mechanism is called for, a yieldingly projected slidably mounted abutment movable by the filling carrier into position to guide the filling carrier when transferred, a lug carried by said dog, a yielding latch carried by the abutment and cooperating with said lug to hold the dog out of operative position until the abutment has been slid into a position properly to guide the filling carrier when transferred, and a stop for limiting the retracted movement of said abutment.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
