ISAAC F. BROVN, OF HYDE PARK, MASSACHUSETTS.

HAT-FORIVIING MACHINE.

SPECFICATON forming part of Letters Patent- No.323,023, dated July 28, 1885.

Application filed February 17, 1885.

To all whom it may concern:

- Be it known that I, ISAAC F. BROWN, of Hyde Park, in the county of Norfolk and State of Massachusetts,a citizen of the United States, have invented a new and useful Improvement in Hat-Forming Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification in explaining its nature.

Heretofore it has been customary, in operating hat-forming machines, to first weigh the wool which forms the bat, and then to feed it to the carding-machine, which forms it into a bat and delivers it to the hat-forming cone; and as lthe wool used is weighed before it is put into the cardingmachine, and as it is necessary to deliver cach quantity thus weighed to the receiving-cone, and as the operator who is attending the delivery of the bat upon the cone cannot know that the bat is ready for delivery until informed by the operator who weighs the bat and feeds it to the carding-machine, itfollows that there is a considerable loss of timein the operation which might be saved if the operation of the carding-machine were to some extent continuous, if there were no necessity for first weighing the wool, and if notice were given when a proper supply or quantity of the bat had been fed to the cone; and my invention relates especially to a device whereby this improvement in the operation of the machine is produced, namely, whereby the wool may bc fed to the carding-machine without being weighed, and when a sufficient quantity has been fed to the cone shall indicate that such quant-ity has been fed, so that the operator of the cone may k now that a suflicient quantity has been fed to the cone and may cut the bat.

The improvement consists, especially, of a device adapted to be operated by the doftershaft or some other revolving part of the cardingmachine, and to indicate when a predetermined quantity or amount of bat has been formed and fed, and as the bat is formed regularly and uniformly, so that a certain area of it will weigh so much, the necessity of previous weighing, if the extent and area which has been fed is known, becomes unnecessary, and the wool can be fed continuously, so that substantially a continuous bat can be formed.

l j Referringto the drawings, Figure 1 is a front elevation of a machine containing the features of my invention. Fig. 2 is a plan view thereof. Fig. 8 is an elevation, enlarged. Fig. 4 is a vertical section upon the line yy of Fig. l. Fig, 5 is a representation of the back side of the machine with the gong removed. Fig. 6 is a detail view. Fig. 7 is a vertical section upon the line sv x of Fig. l.

A represents the shaft of a doffer, and upon its end is mounted the spur-gear a, which meshes witha spur-gear, a', upon the shaft a2. This shaft is supported by the bracket c3, which is bolted or otherwise secured to the frame of the machine, and carries at its front end the bevel-gear at, which meshes with the bevel-gear a5 upon the shaft as. This shaft is supported at its inner end by the sleeve a7 upon the arm a8, which has bearings a9 upon the shaft c2, so that the shaft c has a vertical swinging movement upon the shaft a2. This movement is provided the shaft for reasons which will hereinafter appear. The shaft a carries a cam, B, and a worm, C, which engages with the spurgear c and revolves the same. It preferably has at its outer end the weight c for holding the worm down to its work, and for insuring the quicky return of the shaft when operated, as hereinafter described. It is desirable that the device should beso constructed that once adjusted it shall always indicate,un til otherwise adjusted,the delivery of apredetermined quantity or length of bat. It is also necessary to provide the device with an adjustment whereby it may be set to indicate the delivery of bat of any length for hats of all sizes and weights. These objects are accomplished by mechanism which governs the time of contact of the worm with the spurgear, and it comprises the wheel or disk D, upon the shank d which has a dovetail or 11ndercut recess, d,on its face which receives the end d2, of a bolt, d3, which passes through the end of the arm or lever (hand which is clamped to the wheel by means of the clamping-screw d5, so that,upon the revolution of the plate or wheel D, the lever, which is secured to the shaft d is caused to be moved to operate the device for disengaging the worm C from the gear o. The wheel carrying the lever is moved upon contact of the pin or projection c2 on the spur-wheel c with the pin or projection d,

ICO

which extends through the upper end of the arm or lever (1*, and this movement of the lever causes the pin dwhioh enters the slot e in a horizontal arm, E, to finally come in contact with the arm and move it horizontally in the direction of the movement of the spur wheel and lever d4, and this movement of the arm operates to lift the latch e, on the end of the bell-crank lever which is pivoted at c3, from the stud orvpin e'1 Aupon the swinging block e5, and this swinging block,upon therelease of the latch and the movement of the shaft a, so as to bring the cam B into proper position ,is drawn under the cam by the spring e, so that the cam will rest thereon, and upon the continued revolution of the shaft it is apparent that the cam will ride upon the uppeiI surface of this block or piece and will lift the shaft a. so as to disengage the worm from the gear c, and when the worm is so disengageda spring, F, one end of which is attached to theY bracket and the other to the spur-wheel, serves to return the spur-wheel to its original position, and at the same ti meto reverse the movement of the lever d* and the disk or wheel D, and this reverse movement ofthe lever causes the pin Z,Whiclr enters the slot g in the horizontal bar G attached to t-he swinging block eto be moved backward sufciently to bring the latch stud or pin e in line with the recess in the latch e,which shuts automatically there` on and holds it in that position until it is again released upon the forward movement of the lever d4. The disk or wheel D has a projection, H, against which the stud or pin c2 on the spur-wheel c strikes upon its backward movement; and it serves two purposes, first, as the wheel D has been moved a portion of a revolution upon the forward revolution of the lever d it upon the reverse movement ofthe spur-wheel c, and upon contact with the lu g 0r projection c2 therewith, moves the lever or arm d4 back to its original position;l second, it then acts as a stop in preventing the further reverse movement of the spurwheel. It is obvious that by changing the position of this stop H that the extent of the movement ot' the spur-wheel,befo1e the disengagement of the worin, may be varied-that is, by moving the stop in one direction the spur-wheel will make a larger part of a revolution before the disengagementof the worm, and that moving it in the opposite direction it will make a smaller portion of a revolution; and this movement of the stop is accomplished by simply loosening'thclocking-nut Z5 at thelower end of the arm or lever d", and turning the disk or wheel D to bring the stop H into the desired position, when the locking-nut is again turned to clamp and lock thelever to the wheel.

To indicate when the spur-gear has reached the end of the movement which it is set to make, I have arranged upon the shaft d the lever M, which carries at its end the pawl m, which has the inclined surface m, on which the end m2 of the bell-crank lever ma rides as the lever M is being moved forward, so that the forward movement causes the tongue or striker m4 to be brought in contactlwith the gong or bell. Immediately following the striking of the bell ,the end m2 ofthe lever rides over the pawl, and upon the backward or reverse movement of the lever M the pawl moves on its pivot backward until it has cleared the end of the bell-crank lever, when,by the spring ma, it is returned to its original position, or that represented in Fig. 4. The spring m serves to keep the end m2 of the lever mi in contact with the pawl.

I of course do not confine myself to the especial form of mechanism for connecting the shaft d with the bell-halnmer, but may use any mechanical equivalent for the device herein described.

The disk D may be provided with marks to indicatewhere it should be set to indicate the feed of varying lengths or quantities of bat. In practice the disk or wheel D is set to cause the alarm to be sounded upon the doifer running the number of revolutions which it is necessary for it to make in producing the quantity or weight of bat which the hat then being made requires, and upon the revolution of the doffer movement is communicated to the spur-wheel c, which is revolved until it causes the operation of the tripping mechanism, which allows to be brought into place the device upon which the cam rides in automatically disengaging the driving mechanism, and upon the disengagement the parts ret-urn automatically to their normal position, the worm again engages with the teeth of the spur-wheel, and upon the operation of the doffer the device is again operated as before, and theala'rm sounded to indicate the time when a certain extent or quantity of the bat has been made and fed.

It will be observed that the lever or arm (Z4, attached to the wheel or disk D, operates to trip the latch c, which permits the caml'ifter to be moved into operative position. It will also be vseen thatV upon `the reverse movement of the spur-wheel the cam-lifter is withdrawn, held, and latched back by the latch e.

Of course, while I have illustrated this indicating device as especially adapted for operation upon a hat-iorming machine, yet I would not be understood as limiting the invention to that class of machines, for ofcourse it may be used upon any machine where it is desired that an alarm shall be sounded or indicated at the end of a certain number of revolutions of any part of the machine.

I have referred to the machine to which my invention is applied as a hat-forming machine. I mean to be understood by that, a machine which consists of the wool-carding machine, which prepares and feeds the bat, and the machine which receives the bat from the wool-carding machine and winds it about the hat-forming cone.

Of course the invention can be applied to any wool-carding machine where it is desired IOO IIO

IIS

to indicate the quantity, Weight, or Width of the bat being carded and fed. j

Having thus fully described my invention,
