ATTACHMENT FOR RING-SPINNING FRAMES.

Specification of Letters Patent.

Application filed May 28, 1909. Serial No. 498,83

To all whom it may concern:

Be it known that I, ALFRED ADELBERT LOVEJOY, of Lowell, in the county of Middlesex and the Commonwealth of Massachusetts, have invented certain new and useful Improvements in Attachments for Ring- Spinning Frames, of which the following description and claims, with the accompanying drawings, is a specification.

Like numbers on the drawings denote like parts.

This invention is an improvement in such attachments for ring-spinning-frames as embody hoppers, magazines, or.receptacles, in which travelers may be placed in bulk and retained until the bunches or chains in which travelers-in-bulk are so often found, shall have been disintegrated and the travelers shall have been delivered, a few at a time, into a pan or receiver. It is adapted for the convenient reception, retention, and delivery of travelers of. any size. It is especially adapted to the disintegration of bunches and chains of the smallest and lightest travelers in use.

Bunches and chains of travelers of the smallest size and of the lightest weight are particularly difficult of disintegration. I have found that such disintegration is readily effected by the sudden or concussive shaking of the bunches or chains in asuitable receptacle and I have invented a disintegratingand-delivering traveler-magazine in which bunches or chains of travelers of the smallest size and of the lightest weight, as well as such as are larger and heavier, can be thus suddenly or concussively shaken and disintegrated with great efficiency.

It is essential to the simplest form of my invention that the receptacle for travelersin-bulk shall be movable as an entirety with respect to its stand, and that its motion with respect to its stand shall be guided and controlled by mechanical means. I prefer to embody in my invention, as subordinate features thereof: mechanical means for moving as an entirety such receptacle with respect to its stand; mechanical means for suddenly starting such motion; and, mechanical means for suddenly stopping such motion.

The construction of my invention which I prefer, is represented in the accompanying drawings and described below.

The preferred construction can be departed from in many particulars without departing from my invention.

In the drawings: Figure 1 represents the invention in side-elevation, attached to the creel-board of a ring-spinning-frame, a part of which is shown in cross-section; Fig. 2 rep- In the figures: 1 represents the stand;-

22, the bearings therein for the reception of the shaft; 3, the pan or receiver, for disintegrated travelers; 4, the foot, for attaching the stand to the spinning-frame 5, a portion of the creel-board of the frame; 6 6, means for fastening the stand to the creel-board; 7, a flat recess in the stand having parallel sides for the reception of the flat spring; 8, a hole to receive means, such as a bolt, for fastening the spring to the stand; 9, the means for fastening the flat spring to the stand; 10, the cam-shaft; 11, the rotatable cam, mounted upon and fastened to the cam-shaft; 12, the crank, integral with the cam-shaft; 13, the fiat spring fastened upon the stand and to the receptacle, for controlling the motion of the receptacle and for actuating it, when it is moved in opposition to the action of the cam; 15 15 means for fastening the fiat spring to the receptacle; 16, the receptacle; 17, the cam-shaped projection from the receptacle, for co-acting with the rotatable cam 11; 18, the face of the cam-shaped projection for co-acting with the rotatable cam 11 having its rectilinear elements parallel to the axis of rotation of the cam-shaft; 19, the face of the cam-shaped projection for co-acting with the rotatable cam having its rectilinear elements inclined to the direction of such axis; 20, the orifice for the delivery of travelers a few at a time; 21, the recess in the receptacle having parallel sides for the reception of the adjustable mouth-piece; 22, the adjustable mouth-piece for the orifice; 23, the handle of the adjustable mouth-piece; 24, the adjusting slot of the adjustable mouth-piece; 25, the hood of the adjustable mouthiece 26, the securing means for the adjustable mouth-piece; 27, the cover for the receptacle; 28 28, fastening lugs projecting from and integral with the cover and con- Patented Aug. 31, 1909.

tacting with ledg'es of the receptacle; 29 29, ledges of the receptaclefor receiving the sald fastening lugs; 30, the lug projecting from the lower side of the cover a-nd'containing the bearings for the fastening-bolt; 31, the fastening-bolt; 32, the slot, looking downward and guiding and controlling the motion of the stop that projects from the fastening-bol t; 33, the stop, preferably, a projecting pm through the fasteningbolt, which prevents that bolt from moving too far forward by contacting with the lug at the end of the slot,

and which preventsthe rotation of that bolt; '34, the spring, pressing against the fastening bolt 31 and the lug 30, which forces the bolt forward and controls its position 35, the in- V clined-lip of the receptacle, that forces back The front portion of the fastening-bolt is sufficiently tapered to make it easy to enter itv again into the hole 36 upon the replacement of the cover. The ,upper part 37 of the tapered portion of the bolt 31' contacts with the part 38 of the receptacle at the top of the hole 36, when the cover is in place and the pressure of the spring 34 wedges the receptacle tightly to the cover and tends to prevent the rattling thereof. The extreme front end of the bolt 31 is sufficiently large and flat to conveniently receive the toolthat is used in forcing it backward. Preferably, the ledges 29 29, are reinforced on both sides but they may be the upper parts of sockets, holes opening entirely through the wall of the receptacle, or of other depressions in the walls of the receptacle. A great variety of shapes may be given to the receptacle without departing from my invention. Preferably, the bottom slants toward the orifice 20,

I which is preferably located in the lowest part of the receptacle.

The mechanical means for controlling the jmotion'of the receptacle can be greatly varied. I prefer to use, as such means, a flat spring, mounted upon the stand 1 in a recess of the width of the spring and with parallel sides for preventing the spring from turning upon the fastening means 9 as upon a pivot. I prefer to secure-the spring to the receptacle by two rivets 15 15 at the rear of "the receptacle, as is shown in Fig. 4. This preferred'means, the flat spring, is simple, inexpensive, and permits a slight lateral and an extended vertical movement of the receptacle. In some cases, I stop the downward motion of the receptacle by the face of the rotatable cani as it approaches the re-' ceptacle to elevate it again, but I prefer to elevate the receptacle by means of the rotatable cam 11 and the face 18 of the cam-like projection 17, which tends to move the receptacle chiefly in a vertical direction, and to return the receptacle during the contact of the cam 11 with the face 19 of the cam-like projection 17 whereby a sidewise or lateral shifting, as well as a downward motion, is produced. hen the mechanism is of the preferred construction, it is capable of being operated by turning the crank in either di rection. When the crank is turned in such direction as will elevate the receptacle by the cooperation of the cam 1.1 with the face 10 of the cam-like projection, the lateral motion of the receptacle is much more energetic than when the crank is turned in the opposite direction and a reversal of the crank-motion will sometimes separate a number of travelers from the bunch. In the preferred means for arresting the motion of the receptacle, the downward motion is arrested and reversed by sudden contact with the cam 11. as it approaches the cam-like projection 17 to suddenly elevate the receptacle again, and the sidewise motion is arrested by the stillness of the spring.

While I prefer to elevate the receptacle by means of the rotatable cam and to arrest the motion of the receptacle by contact with that cam as it rotates, I can, without change in the construction of the attachment, suddenly elevate and depress the receptacle wholly by hand, and, without the use of the cam, disintegrate the travelers from the bulk and discharge them through the orifice. I can also, without change in the construction elevate the receptacle by hand and allow the spring to snap it back until it is stopped by contact with the stationary cam, and thus disintegrate travelers from the bunch and discharge them through the orifice.

' Ring-spinning-travelers vary very greatly in size and in weight. The standard (Wilson) sizes vary from #73 weighing 15.8 grains to the traveler to #23/0 weighing onetenth of one grain to the traveler. The #1/0 size measures across the bow about .2312 inch and has a thickness of about .0624 inch, while the #21/0 size measures about .2135 inch across the bow and has a thickness of only about .0139 inch. I have invented an adjustable mouth-piece 22 for use in adjusting the size of the orifice to the size of the travelers to be discharged therethrough. It consists, preferably, of: a strip of sheet metal having a handle 23, bent toward the front; an intermediate part, through which the adjusting slot 24 is perforated; and the hood 25 whichcooperates with the receptacle at the orifice. Preferably, the mouth piece 22 slides in a recess of its own width and having parallel sides, milled in the receptacle, and

it is secured to the receptacle in thedesired position of adjustment by the clampingscrew 26. The inner face of the mouthpiece is preferably a plane surface and the distance of the lower edge of the plane surface from the lower edge of the orifice can be greatly varied to accommodate varied sizes of travelers.- The hood of the mouth-piece is an important feature thereof. It prevents the travelers from being thrown far forward and directs them into the pan or receiver. The inner face of the front part of the hood is preferably at least as far in front of the receptacle at the orifice as the traveler measures across the bow. For travelers varying in size from #1/0 to #23/0 this distance should be a little greater than about .2312 inch. That is a little greater than one-quarter of an inch, and this distance will not require adjustment, except for travelers larger than #1/0. But the height from the bottom of the plane surface of the mouth-piece to the lower edge of the orifice of the receptacle shouldbe a little more than .0624 inch, or a little more than one-sixteenth of an inch for #1/0 travelers, while it should not be much more than .0139 inch or about 1/32 of an inch for #21/0 travelers. The most forward part of the hood is preferably connected with the rearward and plane part of the mouth-piece by a top and sides all, preferably, integral and its extreme lower part is slightly bent toward the rear. The hood is open at the bottom for the escape of travelers and prevents travelers from shooting over the edge of the pan on to the floor.
