PNEUMATIC LINT CLEARER FOR- WABPING MACHINES AND THE LIKE.

Application filed March 12, 19 23. Serial No. 624,368.

To all w 720m it may concern:

Be it known that we, FRANK B. KENNEY and JOHN TV. SIDEBoT'roM, citizens of the United States, residing at Lowell, in the county of Micldlesex, State of Massachusetts, have invented a certain new and useful Improvement in Pneumatic Lint Clearers for lVarping Machines and the like, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention is an improvement in pneumatic lint-clearing or removing devices of the class of that described and claimed in United States Letters Patent No. 1,839,182- granted May 4, 1920, upon applicationof James E. Farrell.

As in the case of the device of the Letters Patent just mentioned, a device embodying the features of the present invention is applicable to warping machines, looms, and other machines in which a series of yarns or threads travel onward side by side; and the improved device is adapted to serve the same general purposes as such formed device, namely that of clearing lint from the yarns or threads, combs, guides, drop-wires, and the like, in the said machines; that of preventing lint from becoming attached to the yarns or threads so as to make slugs or bunches in the cloth into which the yarns or threads are Woven; and that of preventing the stop motion mechanisms of the machines from being rendered inoperative through clogging by accumulated lint.

The invention provides a lint-clearer device of simpler and less expensive character and construction than the device of the said Letters Patent- The latter includes a fan blower which is made to travel back and forth across the machine with which it is combined, by means of a rotating traverse screw having an endless or right and left screw thread, suchtravel being designed to cause the blast or current of air from the blower to act uniformly at all points in the width of the machine. The fan blower of said Letters Patent also is mounted at an inclination in connection with its carriage, and is intermittingly turned step by step around a vertical axis by means of pawl and ratchet devices so as to send the blast or current in different directions successively,

and thereby reach all portions of the yarns or threads and machine, front and rear, in turn.

In the case of a pneumatic lint-clearer embodying the present invention, the blower that is employed occupies a definite location in the machine to which it is applied, and has combined therewith moving means therefor by which the blower is swung transversely of the machine so as to cause the blast or current of air to play back and forth across the width of the series of yarns or threads; and by which, also, the blower is vibrated in a direction at right angles to such swinging movement so as to cause the blast or current to play forward and rearward in the direction of the length of the yarns or threads.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which latter,

Fig. 1 is a front view of a portion of the width of a warping machine having the said embodiment applied thereto.

Fig. 2 is a side view of the machine and lint-clearer device of Fig. 1, certain parts having been removed on

line

2, 2, of Fig. 1.

Fig. 3 is a view in vertical section in the plane of

dotted line

3, 8, of Fig. 1, show ing a series of yarns or threads, the stop motion devices, etc.

Fig. 4; is a partly sectional view on a larger scale, showing the blower and a part of the means for oscillating the same.

Having reference to the drawings,

The drawings represent a typical warping machine and the arrangement, etc., of the lint-clearer device in connection therewith.

In Figs. 2 and 3, yarns or threads 1 are represented as extending through the back comb 2 as if coming from a warper creel (not shown). The said yarns or threads pass from the back comb 2 over a measuring roll 3, under the movable falling rod 4, Fig. 3, over the supporting roll 5, through the front comb 6, and over the front supporting roll 7, from which latter they pass downward to the warper beam 8, whereon they are wound by the action of the machine. Drop-

wires

9, 9, 9, are represented as hung in the usual manner upon the yarns or threads at points between the rear support ing roll 5 and the front comb 6. At 11 is the blower ofthe illustrated embodiment of the invention. It is shownapplied and arranged to operate to blow away lint from the yarns or threads during their passage from rear to front at the top of the machine, and to keep the back andfront combs, drop-wires, and other parts adjacent the drop-wires, in addition to the yarns themselves, tree and clear from lint.

In this embodiment of the invention the blower is mounted in .aposition above the yarns or threads, etc, upon a support 10 in the torm of a shaft extendingaacross-the width of the machine, above the-top of the latter, and mounted in bearings 100 in the upper endsof stands 111 upon the tops of the .sideeframes of the warping :machine. Qnesot suchstandsis partly .loroken.v away in Fig. 2. .Inthis instance the blower is located at .midwidthofi the seriesot yarns 01'. threads, whichis an 'efiective-position for enabling the blower torkeep the yarns or threads-and the desired machine parts clear of lint,v and is an electric/fan 11, whichiis preterred, although the invention-isunotinecessarily restricted in all instancesto theiuse' ota tan blower.

To; provide torswinning movements ot the said. fanll. transverselyof. the machine, it: is mounted between the depending-armsof a hail voryoke 12, that-hangsdown TfPOD'l the supporting shaft 10, thetanwasing being furnished with

journals

13, 13,working-in hearings in connection with the said-harms. The bail or yoke occupies a vertical plane from the fan-casing, and havi-ngfixed onits outer end the disk or: plate 15,-aznd alink 16 coupled at one of its-ends to a crank-pin 17, Fig. l, borne by the, disklo, and at its other end to a pivot pin'lS, Fig. 1, 'fixed at the outer extremity of a suitable member which is in turn fixed upon the bail or yoke 12, such as an arm 19 havlngthe attaching,portion thereof fixed .1,-11 a llO lQpP-OV-IQlQCl. for .it in ,one armot' the bail or yoke.

To provide tor. the convenient connection of the yoke with the supporting. shatt.1-0,a

The bailor yokeis providedwith-a hub 40 which fits. upon the said stud. or pin, and a clamping screw 4-1 applied-to the said "hub serves to holdithebail oryokeiinplace upon the. stud or pin, with capacity for adjustment up and idownto vary the height of thefan. above: the yarns. or :theearlaete,

In this instance, welhknown devices, tuated by :the .no tatio nof the tan, itself, are

In this instance, such switch is indicated at 22, Fig. 3, located at the bottom of one end of the machine. The plunger 220 thereof is arranged to be depressed by a finger 23 upon the pedal rockshaft 24 to close the switch and let the current flow only when the warping machine is running on high speed. In this manner just described the blower is automatically set in action as soon as the warping machine is put on high speed and is caused to oscillate to direct its blast back and forth across the width of the machine.
