CHARLES H. KNAPP, OF PATERSON, NEW JERSEY.

WARPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 661,268, dated November 6, 1900.

Application filed March 6, 1900. Serial No. 7,483. (No model.)

To all whom. it may concern:

Be it known that 1, CHARLES H. KNAPP, a

' citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in \Varping-Machines; and I do hereby declare the following to be a full, clear,.and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to warping-machines, and it has reference particularly to that class of warpingmachines wherein provision is made for compensating for the tendency of the beam to draw the threads onto itself with gradually-increasing speed as the operation proceeds owing to the constant increase in the diameter of the combined beam and goods wound thereon.

One of the objects of my invention is to provide a warpingmachine of the nature above indicated with an improved form of the mechanism whereby power is communicated to the beam for receiving the warp from the driveshaft of the machine in such manner that the tendency of said beam to draw the threads onto itself with constantly-increasing speed as the operation proceeds is compensated for and the pull upon the warp maintained constantly uniform.

It is a further object of my invention to so construct the above-mentioned mechanism for transmitting power from the driveshaft of the machine to the beam that the same may be manually adjusted and also effectively and quickly disconnected when for any reason occasion requires.

The invention consists in the improved warping-machine, and also in the several combinations of the parts thereof, constructed substantially as hereinafter described and finally embodied in the clauses of the claim.

My invention is fully illustrated in the accoiupanying drawings, wherein Figure l is a side view of my improved warplug-machine and also of a creel from bobbins on which the threads are delivered to the machine, said creel and its accessory parts being shown in dotted lines. a front view of my improved warpingnnachine. Fig. 3 is a top plan view of a certain mechanism for indicating or measuring the amount of threads placed on the beam. Fig. 4 shows a certain bracket used in connection with the mechanism illustrated in Fig. Figs. 5, 5, 6, 7, and 8 show in detail the mechanism whereby the tendencyof the beam to exerta gradually-increasing pull upon the thread is automatically compensated for. Fig. 9 is a detail view of a portion of the starting mechanism of my machine, and Fig. 10 is a detail view showing a portion of a certain shaft-shifting mechanism.

In the accompanying drawings the frame of the machine is designated by the referonce-letter c. Projecting rearwardly from the upper end of this frame is a pair of arms a, from which project upwardly vertical guides 0, in which is arranged the frame (t for the reception of the main reed ct of the machine. To the back of the frame a is hinged a bar a carrying a glass rod a, over which the threads of to be wound upon the beam are extended before passing through the dents of the reed and after leaving the bobbins on the creel a a is a pair of standards which support a pair of glass bars a the threads being adapt ed to pass under the me of and parted by the other, as clearly shown in Fig. 1. From the glass bars a the threads extend through another reed b, disposed in suitable brackets Z), and they then extend over a roller 71*, having stationary hearings on the frame a, and thence under another roller b that is journaled in a pair of levers I), which are fulcrumed in brackets b secured to the sides of the frame a. The levers b are adapted to be thrown back into substantially vertical position, so as to remove the roller ['1 from contact with the warp and to be maintained in this position by pawls b, that are adapted to engage notches in the brackets If. The action of the roller against the warp maybe adjusted by means of one or more weights b carried upon upwardly-extending bent arms I), having their free ends hooked so as to prevent the disengagement of the weights therefrom when the levers are swung back. After passing under the roller 12 the threads extend Fig. 2 is 2 comes over a beam 0, which I term the measuringbeam. The trunnions o of this measuringbeam extend through the sides of the frame a and bear upon rollers 0 journaled in one of a pair of brackets 0 secured to said frame. One of the trunnions c carries a pinion 0 which meshes with another pinion 0 thatis secured upon a sleeve 0', said sleeve being itself journaled upon a shaft 0 projecting from the bracket 0 The end of the shaft 0 is squared, the squared portion receiving one end of an arm 0 that projects laterally from the shaft and provides a support for a worm-wheel c whose teeth engage a worm 0 on the sleeve 0 The upper face of the worm-wheel may he graduated, so that by means of a pointer c, which is secured above the worm-wheel by a s rew 0 acting as a bearing for the latter, he amount of material that has passed over the measuring-beam 0 may be measured. In the brackets c is fulcru med a pair of levers d, which carry a roller d and which are also provided with bent arms 01 for the reception of weights d and pawls 01, adapted to engage notches d in the brackets (3 the same as the levers 13 At the front end of the frame is mounted a pair of parallel horizontal rods 0, which connect the sides of said frame. Said rods are adapted to sustain brackets ff, each having split tubular portionsf controlled by thumbscrews f for securing it in various positions upon said rods. These brackets project upwardly from the rods, and the one of themf is provided with a bearingf for one trunnion of the beam onto which the threads are to be wound, while the other of them f is provided with a corresponding bearingf in which is journaled a shaftf, the end of which adjacent the bearingf carries a face-platef adapted to bear against the end of the beam in an obvious manngr.

To the bracket f is secured a gear-casing wherein is freely journaled upon the shaft f a gear-wheel g. The shaft f is provided with a key f which engages a feather in a friction-disk g and in a collar 9 rigidly secured to said friction-disk. When the gear is rotated and the friction-disk is forced against its outer face, the rotary motion of said gear will be imparted, as will be obvious, to the shaftf.

h is a lever which has a loop 71/ formed therein and which is fulcrumed in cars 71 projecting from the gear-casing g below the shaftf. Its loop portion is provided with two inwardly-projecting pins 7L3, which engage a circumferential groove Win the collar g so that by vibrating the lever the collar can be moved longitudinally upon the shaft f carrying the friction-disk with it, of course. Projecting upwardly from the gear-casing is a lug W, in which is fulcrumed an inverted-T- shaped hand-lever it, said lever being conof connection with the link It is remote from the point of connection of said link with the lever h. The hand-lever is adapted to be thrown in the direction of the arrow in Fig. 1 slightly past the dead-center, so as to maintain the friction-disk g effectively against the gear-wheel g, and for this reason its under side is provided with a concavity 7L8 (see Fig. 9) of graduated depth and adapted to receive a pin h", that is carried by an adjustable angular arm h secured upon the top of the gear-casing and having a slot h which receives the screw 77, for securing it in place. The arm is rendered adjustable by means of a set-screw 72, set into it and bearing against the side of the gear-casing. It will be seen that by adjusting the arm to and from the gear-casing the point of the pin 71 will be brought to where it can project to a greater or less distance, as required, into the concavity in the lever h, so as to insure the securing of the lever in the desired position without materially releasing the friction-disk from contactwith the gear after the line of dead-center has been passed. The lever h is provided with a downwardly-projecting leg 1, which is join ted to a horizontal pitman i, said 'pitman being connected to an arm i projecting from a vertical rod i hereinafter more particularly referred to.

Beneath the pair of rods e is journaled a shaftj, the same having hearings in and connecting the two side portions of the frame a. This shaft carries a gear j, which meshes with the gear g, and at one end it carries a bevel-gearfi.

From the side of the frame a to which. the bevel-gearfiisjournaled project two brackets k, the one being disposed above the other. These brackets provide bearings for a vertical revoluble shaft k upon the upper end of which is mounted a bevel-gearlc that en gages the bevel-gearf. Near this shaft is journaled in the frame a a horizontal shaft M, which shaft is provided with a pulley k and is the main drive-shaft of the machine. This shaft k is provided at the end thereof adjacent the shaft with a friction -disk 76 against which frictiondisk bears the periphery of a friction-wheel 75 said friction-wheel being adapted to rotate with the shaft 70 by virtue of a key 7 ,WhlCh engages a feather in the bore of said friction-wheel 70 The friction-wheel 70 carries an integral circumfercntially-grooved collar 76 ,Wlill which engages the forked end of an arm 70 that projects from an internally-threaded sleeve 76 which is penetrated by and engages a threaded revoluble shaft 70 also journaled in the brackets 70 It. The upper end of the threaded shaft 70 is provided with a hand-wheel 7e whereby it may be manually rotated. Near the lower end of the shaft 70 is disposed another fric tion-wheel Z, that is supported on a bracket Z which is penetrated by and engages the threading of another threaded shaft Z that is journaled in the brackets 70 It to one side lOO senses a of the other two shafts k and The friction-wheel Z is loosely mounted on the shaft k and it may be adjusted longitudinally upon the same by manipulating a hand-wheel Z' that the upper end of the threaded shaft Z carries. As shown in Fig. 8, the friction wheel Z consists of a sleeve Z", having a sur rounding flange Z near one of its ends and penetrating a disk Z, between which and the flange are secured disks Z of paper, leather, or other suitable material, the flange and the disk i being clamped together by screws l penetrating them and the disks Z If desired, the construction of the other frictionwheel 70 may be similar to that just described. Upon the upper end of the sleeve Z" of the friction'wheel Z is secured an eccentric Z which receives an eccentric-strap Z from which projects an arm Z The friction-wheel is kept down against the bracket Z by means of a collar Z which is secured upon an integral sleeve Z projecting upwardly from said bracket 1*.

The bracket Z has a recess Z in its end, which receives the shaft 70 and it carries a ratchet-wheel on, which is journaled on said shaft and above which is fulcru med, also on said shaft, a lever m", that is pivotally connected at one of its ends to the lever Z and at thg other of its ends carries aspring-actuated pawl m which engages the teeth of the ratchet-wheel. The pawl m is provided with a downwardly extending lug m", against which bears a finger m, that projects from the shaft 0?, hereinbefore referred to, said shaft having bearings in the two brackets 70 7c. The finger is keyed upon the shaft so as to be movable vertically thereon when lifted by a projection m on the bracket Z In order to maintain the friction-wheel Zin proper contact with the friction-disk it, the bracket which carries it is pressed toward said disk, having a tendency to move about the shaft 1- by a spiral spring 91, that is disposed hetween a projection 12/ on the bracket and a bar it, that connects the brackets is and 7t. From the projection n extends a threaded pin ta which protrudes through a slot at in the bar n and is provided with an adjusting-nut 92 The shaft M has a slight longitudinal movement in its hearings in the frame a, so that the friction-disk which it carries may be thrown into and out of contact with the two friction-wheels 7c and Z. In order to move the shaft longitudinally in its bearings, I have provided a lever 0, which is fulcrumed in a brace 0, connecting the side portions of the frame, and which is connected by a pitman o with a bell-crank lever 0 said bell-crank lever being also fulcrumed in the brace and having its upper end forked and provided with opposing pins 0 which work in a slot 0, that is formed between two collars o 0 suitably secured upon the shaft. From the bell-crank lever projects a lug 0 which is disposed in opposition to a bent arm o that projects downwardly from the stubshaft 0, upon which the lever 0 is fulcrumed, said arm and the lug being connected by a bolt 0 about which is coiled a spiral spring 0 that acts to force apart the lug and arm; It will be seen that the spring therefore normally acts to maintain the friction'disk in contact with the friction-wheels. The lever 0 is provided with a handle 1) and pawl 19, the latter being adapted to engage the teeth of a rack 29 that is secured to the side frame and is shown in Fig. 1, but is best shown in dotted lines in Fig. 2.

Assuming that the drive-shaft 70 is driven from its pulley 70 in the direction of the arrow in Fig. 1, in the operation of the machine the attendant grasps the lever 13 and lifts upon the same, so as to force the frictiondisk carried by said shaft toward the frictionwheels, whereupon the lever is secured in the position for maintaining the contact between the friction-disk and friction-wheels by its pawlp' and the rack 19 With his other hand the attendant grasps the lever h and pushes the same from him until the link which connects this lever with the lever h is forced past its dead-center and the pin 7L9 contacts with the lever in the concavity thereof. It should be remarked that the machine is of such length that the simultaneous operation of both these levers can just be effected with convenience. In setting the lever h, as above described, the consequent movement of the lever 72, has forced the friction-disk g against the face of the gear-wheel g, so that the rotary motion that is imparted through the friction-wheel 767, the shaft the bevel-gears k and the shaft j, and the gears and y is finally transmitted to the shaft f and consequently to the beam which is journaled between the face-plate f and the bracket f The setting of the lever h has also effected in an obvious manner the partial turning of the shaft i whereby the finger m is actuated to permit the pawl m to engage the ratchet- Wheel. It will be seen that by working the lever h" in a reverse direction of course the frictiondisk will be immediately disconnected from its driving means, thus stopping the rotation of the beam, and the rod i will be turned, thereby throwing out the pawl m and thus simultaneously stopping the automatic adjusting of the friction-wheelkflwhile the re lease of the leverp,which is of snfficient weight to counteract the action of the spring 0 and draw the friction-disk 71'. out of operative contact with the friction-wheels, will disconnect the intermediatedriving mechanism by which power is transmitted from the friction-disk 70 to the frictioirdisk g Now as the friction-disk Z revolves the eccentric Z which it carries, imparts an oscillating movement to the lever Z which in turn vibrates the lever 'm, whereby the pawl m is actuated. As the pawl turns the ratchet-wheel in a rotary motion is imparted to the shaft k (by virtue of the fact that the ratchet-wheel is keyed upon the shaft,) which action tends to feed IIO the sleeve and consequently the frictionwheel is, which is carried at the end of its arm, downwardly, as will be manifest. Thus, though as the threads wind on the beam the extremediameter of the latter practically increases and said beam therefore tends to exert a leverage on the unwound portion of the threads that is constantly increasing, the speed at which the beam is rotated is gradually being reduced and the tendency referred to is overcome. In view of the fact that the threads may be wound on different beams in different thicknesses and at various rates of speed in attaining a given diameter I have provided in the hand-wheel 70 for manually revolving the shaft 70 and in the hand-wheel Z for likewise revolving the shaft Z means for adjusting the two friction-wheels relatively to the center of the friction-disk. The effect of the adjustment of the respective friction-wheels will be apparent.

By providing the several rollers over and under which the threads have to pass before being wound on the beam and some of which are weighted I accomplish in one machine as well, if not more perfectly, what is accomplished where a reel, as at present, is auxiliarly employed for transferring the threads from the creel onto the beam.
