HAT-POUNCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,574, dated December 14, 1880.

Application filed September 30, 1880. (No model.) I

To all whom it may concern:

Be it known that I, CALVIN J. SARGENT, of Methuen, in the county of Essex and State of Massachusetts, have in vented certain Im pro vements in Hat-Pouncing Machines, of which the following is a specification.

This invention relates to that class of hatpouncing machines in which the pouncingsurface is made adjustable and the bed fixed, as shown in my Patent No. 226,554, dated April 13, 1880, the pouncing-surface being preferably a belt coated with a suitable abrading material, supported over the bed by a roll, as shown in the patent to A. L. F. Mitchell, November 11, 1879, No. 221,594.

In the machine described in said Patent No. 226,554, the pouncing-surface, which is also a belt coated with abradin g material supported by a roll, is adjusted toward and from the bed by being inclined at different angles--the' roll, or the shaft supporting it, being pivoted to allow the roll to swing in avertical plane. This method of adjustment causes one end of the roll to be raised and lowered farther than the other, so that the roll cannot be kept parallel with the bed in all positions to which it can be adjusted.

The present invention has for its object to enable both ends of the roll to be moved equally when the roll is'adjusted, so that under all adjustments the same relative distance of both ends of the roll from the bed will be preserved.

The invention also has for its object to enable the roll to be inclined relatively to the bed, so that the space between the roll and bed will be narrower atone end than at the other, the uniform adjusting movement of both ends of the roll preventing the relative distance of the ends of the roll from the bed from being changed when the roll is adjusted to vary the width of said space.

The invention also has for its object to provide certain improvements relating to the supporting-bed, and the combination of the bed with the file-roll, and also to provide means to prevent the adjustment of the counter-shaft to vary the tension of the pouncing-roll from affectin g the belt which drives the file-roll, said belt being driven by the same countershaft that drives the pouncing-belt.

To these ends my invention consists in the improvements which I will now proceed to de scribe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents an end view of a hat-pou'ncing machine embodying my invention. Fig. 2 represents a front view of the same. Fig. 3 represents. a section on line 00 00, Fig. 2. Fig. 4 represents a section on line y 3 Fig. 1. Fig. 5 represents a section on line 2 2, Fig. 1. Fig. 6 represents a section on line 00 m, Fig. 1. Fig. 7 represents a top view of the machine. Fig. 8 represents a modification.

The same letters of reference indicate the same parts in all the figures.

In the drawings, A represents a general frame, of any suitable construction, to support the parts hereinafter described. In the present instance the frame is bolted to a bench, B; but, if desired, it may have suitable legs forming a part of its structure.

C represents the endless pouncing-belt, extending from a counter-shaft, D, at any suitable distance from the frame A to a roll or pulley, E, which forms a part of the pouncingmachine, and is supported as hereinafter described. F represents the supporting-bed under the roll E, said bed having certain peculiarities of construction, hereinafter described, and being supported byan arm or standard, G, suitably supported from the frame of the machine or otherwise. H represents the fileroll, which feeds the hat-body to the pouncingsurface; and I represents the bed, which. co-

operates with the file-roll, said bed being'simi- 'lar to the bed F.

If desired, a single bed wide enough to serve both for the pouncing and file roll may be substituted for the two beds F I 5 but I prefer to make the beds as shown, so that one may be adjusted independently of the other, if required.

The roll E is a substitute for the roll C shown in my above-named patent, and, like the last-named roll, is adjustable vertically, toenable the pouncing-surface to be brought nearer to or farther from the bed. Instead of adj usting the roll by moving it more at one end than at the other, as in my previous patent, I provide means whereby the roll E may be moved alike at both ends, so that the inclination of the roll will not be changed by raising or lowering it. To this end I provide a frame or block, G, having arms G G, supporting boxes which receive the journals H H of the roll E, and connected by pivots l I to suitable ears or flanges, K K, formed on the frame A. The pivots I I are parallel with the surface of the bed F, so that when the frame or block G is turned. the roll will be raised or lowered, and its movement will be the same at both ends.

The tension of the pouncing-belt G is sufficient to hold up the roll E and keep it normally separated from the bed F about threeeighths of an inch, more or less.

To depress the roll E and bring its pouncin g-surface nearer the bed E, I employ a pedallever, L, connected by a rod, M, with an arm projecting from the rear end of the block G, so that by a pressure of the operators foot the roll E can be brought as close as is desirable to the bed.

This feature of my inventionviz., the equal motion of the roll E at both endsenables me to give a uniform thickness to all parts of the hat-body, and to work on hats of varying thickness. It is often desirable, however, to vary the thickness of each hat-body, making the crown thinner than the brim, or vice versa and to effect this I construct the frame G so that the roll can be inclined relatively to the bed and positively held in an inclined position. To this end 1 make the yoke G, that supports the roll E, in a separate piece from the block G, and provide it with a trunnion, G which is fitted to turn in sockets formed in the block, the trunnion being substantially at right angles with the pivots I I of the block. The roll E is thus adapted to be inclined, and is held either in an inclined or a horizontal position by means of an arm, N, rigidly attached to the trunnion G and projecting upwardly into a cap, 0, on the block G, and a screw, 1?, fitted to turn without moving longitudinally in said cap and passing through a threaded orifice in the arm N, as

1 shown in Fig. 4. By turning this screw the arm N and trunnion G can be turned to vary the inclination of the roll E,as will be readily seen.

The supporting-bedsFIare each composed of ablock of wood, 1, and a plate of glass, 2, set into the top of the block and forming the bearingsurface of the bed. I have found that glass is the best material for the purpose, because of its smoothness, which allows the hat to be very easily moved about, and its hardness, which prevents it from being worn away.

It is very important that the surfaces of the bedsshould be perfectly free from depressions, the slighest wear being detrimental to the operation of the machine.

Heretofore the bed or beds have had to be frequently renewed; but I find that a glasssurfaced bed is practically proof against wear resulting from the ordinary operation of the machine.

The file-roll H is secured to its, arbor R by set-screws TT, as shown in Fig. 6, and the roll is thus adapted to be adjusted longitudinally to vary its position with relation to the bed I.

l have found that by shifting the position of the file-roll to vary the distance of its ends from the ends of the bed,Ican better suit the machine to the requirements of different styles and shapes of hats. I do not limit myself, however, to making the file-roll adjustable, as the bed I may be -made adjustable for the same purpose, if desired. The bed I may also be adapted to be raised and lowered, if desired, to vary its distance from the file-roll; but in all cases the bed F, under the roll E of the pouncing-belt, will be fixed, the described adjustments of the roll E being sufficient for all required variations of the space between the pouncing-surface and the bed F.

The counter-shaft D, which drives the belt 0, is Vertically adjustable, in order that the belt C may be tightened when it becomes stretched. The belt U, which drives the fileroll, is run from the same shaft; and to prevent the adjustment of the shaft from affecting the belt U, I run said belt upon apulley, V, which, instead of being on the arbor of the file-roll, is journaled on a stud, W, which is supported in a slot, a, in a plate, I), suitably attached to the frame A.

To the pulley V is rigidly attached a pinion, 0, which meshes with a pinion, d, on the arbor of the file-roll. The slot (1 is concentric with the center of the file-roll, and the stud W is adapted to be moved in the slot and secured at any desired point, so as to accommodate the pulley V to the height of the counter-shaft.

It is obvious that so far as the described adjustments of the roll E are concerned my invention is not confined to the employment of the pouncing-belt, as the roll E may have its periphery coated with abrading material. I much prefer the use of the belt, however, for the reason that it affords a large extent of cutting-surface, removes the dust from the body of the hat, and does not become heated in operation.

I do not limit myself in all cases to the glasssurfaced beds F I, as the rolling bed shown in Mitchells Patent No. 221,593, dated November 11, 1879, may be employed, if desired. I prefer the use of the glass-surfaced beds, however, for the reasons above stated.

In the usual operation of the machine the roll E and the file-roll H are rotated in opposite directions, as indicated by arrows in Fig. 3 5 but, if desired, the file-roll and its bed may be dispensed with and the rotation of the roll E reversed, so that the pouncing-belt will also feed the hat over the bed. In this case I provide a bar, z, in front of the bed I as shown in the modification, Fig. 8, to serve as a sar face against which the operator may hold the hat to retard its movement by the pouncingbelt.

It will be seen that the beds H I are unobstructed at both ends, so that a hat-body may be placed on either end, as in my above-named patent. The file-roll is usually roughened only from one end half-way or more to the other, leaving one of its ends smooth, and as the tileroll is movable on its shaft, it may also be reversed to bring its roughened portion over either end of the bed.

The unobstructed ends of the beds and the reversibility of the file-roll enable the machine to be changed from a right to a left hand machine, and vice versa, so that the same machine can be adapted to pounce both the outer and the inner surfaces of the hat.

I claim as myinventio11 1. In a hat-pouncing machine, the combination, with the bed, the pouncing-belt or its equivalent, and the belt-supporting roll located over the bed, of a frame containing the journals of said roll, and pixoted so that the roll can be raised and lowered equally at both ends, as set forth.

2. In a hat-pouncing machine, the combination, with the bed, the pouncing-belt or its equivalent, and the belt-supportin g roll lo cated over the bed, of a frame containing the journals of said roll, and pivoted so that the roll can be raised and lowered equally at both ends, and constructed substantially as described, so that the roll can be held either parallel Withthe bed or inclined with relation thereto.

3. In a hat-pouneing machine, a supportingbed having a bearing-surface of glass, as set forth.

4. In a hat-pouncing machine, the combination of a file-roll and a bed under the same, one or both of said parts being adjustable endwise, as set forth.

5. In a hat-pounoing machine, the combination of the bed, the roll E over the bed, the pivoted frame containing the journals of the roll, the endless pouncingbelt running on the roll and holding the same upwardly with a yielding pressure, and mechanism to turn the frame on its pivots and force the pouncingbelt and roll toward the bed, as set forth.

6. In a hat-pouncing machine having an endless pouncing-belt and a file-roll, both driven by the same counter-shaft, the latter being adjustable to vary the tension of the pouncingbelt, the means whereby the adjustment of said shaft is prevented from affecting the belt driving the file-roll, said means consisting of the vertically-adjustable stud W, the pulley V, supporting the driving-belt of the file-roll, the pinion c, rigidly attached to said pulley, and the pinion (l on the arbor of the file-roll, as set forth.

7. In a hat-pouncing machine, the combination of the reversible file-roll and the bed having both ends unobstructed.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses. this 25th day of September, A. l). 1880.
