VHAT-I-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 628,878, dated July 1 1, 1899.

Application filed June 16, 1898. Serial No. 683,585. (No modeld T0 115 whom, it may concern:

citizen of the United States, residing at Yonkers, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Hat- Making Machines, of which the following is a specification.

This invention relates to certain improvements in hat-making machines, and more speciiically to fur-weighing appliances for the same, by which the exact quantity of fur required for one hat is automatically weighed off and formed into a layer of uniform thickness before it isfed to the hatbody-forming cone, said layer being watched by the attendant in its progress toward the forming-cone, so that he can readily remove the cone, with a hat formed thereon, and replace it by a new cone for the next layer of fur.

The invention consists of certain details of construction and combinations of parts to be more fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved hat-making machine. Fig. 2 is a vertical longitudinal section of the same; and Fig. 3 is a detail side elevation, drawn on alarger scale, of my improved weighing attachment.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the fur-feeding mechanism of my improved hatmaking machine; I the automatic weighing attachment, which is located below the furl'eeding attachment; C, a conveyer,which islocated belowthe fur-weighing attachment; D, A

The fur-feeding mechanism A consists of an endless belt (I, provided with pins, which take up the fur from the supply-box A, the

for being removed from the conveyer by a rotary clearer A so as to be dropped into the receiving box or hopper B of the fur-weighing attachment B. The receiving-box B is made stationary and supported in any suitable manner on the casing of the fur-feeding device and is closed at its lower endby a tilting platform BZthat normally closes thelower part of the box or hopper B, as shown in Fig. 2. The tilting platform B is applied to the end of a fulcrumed. lever-frame B which turns on knife-edges (Z of the supportingbracket B said lever-frame being provided lfulorumed scale-beam is supported by means of knife-edges I) on a suitable supporting-arm B, which is attached to the receiving box or hopper B, as shown in Fig. 3. The end of the scale-beam is prevented from being moved in upward direction by means of the stop 5 on the supporting-arm B The tilting finger or latch b at the end of the scalebeam B holds under the influence of the weight b the platform B in closed position, said finger engaging the projection b on the platform and preventing the downward tilting of the same. As soon as the required quantity of fur is supplied to the platform B scale-beam and causes the tilting of the leverframe B until the projection on the platform B clears the end of the pivoted finger or latch.

the fur into an inclined position, as shown in dotted lines in. Fig. 3, until the quantity of suction action of the hat body-forming cone, 1 and M is a mirror, which is supported at a v suitable inclination above the upper conveyor fur collected thereon is slid 0E onto the horizontalconveyerG. Simultaneouslythesoalebeam is returned under the influence of its in such position that the attendantcan readily weight into its normal position until it is arthe machine without requiring the hand-feedattachment and deposited on the conveyerrested by the stop Z As soon as the fur is discharged on the conveyer-apron O the platform is returned by its counterbalancing le- Yer-frame B into its normal position, the projection at its front part lifting the tilting linger or latch sufficiently to permit the clearance of the platform B and its return into closed position at the lower part of the receiving box or hopper B. As soon as the platform has passed the tilting-finger b it assumes its normal position at the end of the scale-beam, as shown in full lines in Fig. 3, so that the projection on the platform B is located above the tilting-finger and permitted to rest on the same while the next charge of fur is being deposited by the fur-feeding devices in the hopper B. The quantity of fur which is thus measured off by the weighing apron U is moved forward with the same and distributed in a layer of uniform thickness by means of two rotary distributers C 0 the fingers of which spread the fur evenly over the conveyer-apron, as shown in Fig. 2. The conveyer-apron C is inclosed by side walls so that no fur can pass over the edges of the same. The fur is spread by the distributers in a uniform layer or sliver on the conveyer C, is then taken up by the two endless aprons E E, that are moved in contact with each other by a suitable mechanism, so that the layer of fur is tightly held between the two aprons, and delivered by the upper end of the same to the second horizontal conveyer-aprou D. From the conveyer D the fit r is conducted between a pair of closely-arranged feed-rollers e 6 onto the rapidly-rotated card-cylinder G, by which the fut-is thrown into the upper part. of the casing which surrounds the hat-bodyforming cone. Under the suction action of the rapidly-rotating perforated hatbodyforming cone the fur is deposited in a layer on said cone until, in connection with the moisture supplied thereto, a hat-body of uniform thickness is formed in the well-known manner.

Motion is imparted to the different parts of my improved hat-mal 1ing machine by means of suitable power-transmit'ting shafts, belts, and cross-belts, as shown in Fig. 1, the various motions being so timed that when the charge is deposited from the weighing attachment on the lower conveyer-apron a second charge is passing along between the upright conducting-aprons and a third charge going forward over the upper conveyeraprou to the rapidly-rotating distributing-cylinder. In this manner a uniform feeding and weighing off of the quantity of for required for a hat takes place by the automatic action of ing of the fur, as heretofore,

The inclined mirror M is so located relatively to the open upper rear end of the conecasing and the upper conveyer-apron that the progress of the fur over the upper-coni veyer to the distributing card-cylint'ler can i be readily observed through the glass-covered openingf in the door by the attendant, who knows thereby exactly when a hat-body is formed on the'cone. He then opens the doors, removes the cone, with the hat-body on the same, passes another cone into the easing, and closes the doors of the casing. During this time another layer of fur rises onto the upper conveyor-apron and is delivered into the casing and brought under the suction action of the forming-cone, so that the next hat-body is formed thereon, and so on. By the window in the casing of the forming cone and the mirror the progress of the for required for each hat can be fully observed by the attendant, and thereby the regular and effective working of the hat-making machine timed and controlled. The fur-weighing attachment produces an accurate and regularsupply of fur required for a hat-body, so that the hand labor for weighing and feeding the for to the hat-making machine is dispensed with and the fur automatically conveyed to the forming-cone andformed into a hatbody under the suction action of the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a fur-feeding mechanism, an intermittentlyacting weighing mechanism com prisinga receiving-box, a tilting plat form adapted to close the lower end of said receiving-box. a connterbalancing scalebeam having a pivoted finger or latch for engaging said platform, and a stop against which said beam abuts when in horizontal position, a hat-body-forming cone, means for conveying the fur toward said cone, and a fur-distributing device at the end of said conveying means, for distributing the fur onto the cone, substantially as set forth.

2. The combination of a fur-feeding dcvice, an intermit tently-act'ing weighing mechanism below said fur-feeding device, said weighing mechanism consisting of a receiving-box, a tilting platform adapted to close the lower end of said box and a fulcrumed counterbalancing scale-beam adapted to engage said platform so as to hold it in closed position, a conveyer located below the weighing attachment, rotary t'listributers above the convcyer, an upper conveyor, inclined aprons moving in contact with each other for conveying the fur from the lower to the upper conveyer, a distributing device at the end of the u pper conveyer, a l1at-bodyforming cone,

and acasinginclosing said cone and distributing device, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
