MACHINE FOR STEFFENING HATS.

SPECIFICATION forming part of Letters Patent No. 426,135, dated April 22, 1890.

Application filed August 9, 1889. Serial No. 320,319, (No model.)

To aZZ whom it may concern:

Be it known that we, FRANK J. MURPHY and ANTHONY M. BUNDLE, citizens of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Machines for Stiifening Hats; and we 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.

Our invention relates to the class of machines described in our former Letters Patent, Nos. 361,073, dated April 12, 1887, and 396,829, dated January 29, 1889, and has for its object to simplify and improve the construction and operation of the machine.

Vith these ends in view we have devised the novel improvements in the details of con struction, which we will now describe, refer-- ring by numbers to the accompanying drawings, forming part of this specification, in which- Figure 1 a plan view of the entire machine; Fig. 52, a section on the line 00min Fig. 1, the legs being broken away, showing the spindle, belt-pulley, cone, clutch mechanism, 850., in elevation; Fig. 3, a side elevation of the portion of the machine that is removed in Fig. 2--that is, the tank, brush-shaft, brush, and adjusting mechanism for said parts 5 Fig. 4:, a section on the line 7 y in Fig. 3, looking toward the right, the tank, however, not being shown; Fig. 5, a detail inverted plan view of the mechanism for determining the throw of the cone; Fig. 6, a detail sectional view on the line in Fig. a, looking down; and Figs. 7 to 11,inclusive, are detail views illustrating the parts of the clampin mechanism detached.

1. denotes the bed of the machine, which is supported by suitable legs 2 and is provided with a slot 3, extending through it.

4 denotes a carriage, which is adapted to reciprocate longitudinally of the bed, and 5 is a gearwheel journalcd in brackets 6, bolted to the under side of the bed. This gearwheel is adapted to mesh with a worm 7 on a shaft 8, extending longitudinally of the machine. Power is applied to this shaft by a belt (not shown) passing over a pulley 9, and the carriage is reciprocated by means of a connecting-rod 10, one end of which is pivoted to the carriage and the other to gearwheel 9, the point of attachment to said gearwheel being adjustable, so that the throw of the carriage may be regulated at will.

In order that the movement of the carriage may be stopped at any instant, which would be impossible if depending upon a shifting of belts, we provide for disengaging worm 7 from the gear-wheelin a manner which I will now describe.

11 and 12 denote,respectively, therearand front boxes, in which shaft 8 is journaled. The rear box is provided with an arm 13, which is pivoted to a bracket 1-lon a cross piece 15, extending between the two rear legs of the machine. It willbe seen that this con-. struction permits oscillation of the shaft and boxes in the vertical plane. The front box 12 is provided with an arm 16, having a slot 17 and at its upper end a hook 18. A bolt 19 passes through slot 17 and through a bracket 11, attached to a cross-piece 15, extending between the two front legs of the machine.

20 denotes a strong spring, one end of which is connected to the under side of the bed and the other to hook-1S upon the front box of So the shaft.

21 a foot-lever pivoted to a suitable bracket 22, and 223 is a link connecting said foot-lever to box 12. The foot-lever extends outward beyond the front of the machine in 8 5 such a position that an operator standing at the front of the machine may readily place his foot upon it. It will be seen from Fig. 2 that the action of spring 20 will be to hold the worm in engagement with gear-wheel 5, 0 so that the carriage will reciprocate continuously until its movement is stopped by the operator pressing down upon the foot-lever and disconnecting the worm from the gearwheel.

2st denotes the spindle, whichis mounted in boxes 25 on standards 26, extending upward from a turning plate 27, which is secured to the carriage by a bolt 28. Anti-friction rollers 29 are preferably placed in the carriage, 10o upon which the turning plate rests, so as to permit said plate to oscillate freely. At the forward end of the spindle is a cone 30, shown as having a hat-body 31 thereon. The body upon the cone is held in position by clamping-arms 32, pivoted between ears 33 at the rear end of the cone and provided with adjustable clamping-surfaces 34. These clamping-surfaces are preferably secured in position by means of thun1b-screws 35, which pass through slots 36 in the clamping-arms. The clamping-arms are operated by means of rods 38, the outer ends of which are threaded to engage hubs 39, which are journaled at the rear ends of the arms, turning freely therein. (See Figs. 1 and 11.) The other ends of the rods are pivoted between ears 40 on a ring 41, which is rigidly secured to a sleeve 42 upon the spindle, the latter being provided with a spline 43, engaging a corresponding groove (not shown) in the sleeve, whereby the latter is held againstrotation independently of the spindle, but is allowed to slide longitudinally thereon. It will be seen that by means of the threaded outer ends of the rods and hubs 39 we are enabled to adapt the clamping-surfaces to different thicknesses and qualities of hat-bodies, and by means of bolts and slots 35 and 36 we are enabled to adjust the clamping-surfaces to different sizes of hat-bodies.

44 is an operating-lever, the central portion of which is bifurcated, and then reunited to permit it to embrace sleeve 42. The lower end of this lever is pivoted to ears 45 upon the turning plate, and the upper end is provided with a handle for convenience in operation. I

46 denotes half-collars, which lie in a groove 47 in sleeve 42. The opposite sides of the central portion of the operating-levers are connected to these half-collars by bolts or pins 48.

49 denotes a belt-pulley, which is adapted to turn on the spindle, and is provided at its forward end with clutch projections 50.

51 denotes a sleeve on the spindle, which engages a spline 52, whereby it is held against rotation independently of the spindle, but allowed to slide freely longitudinally thereof. Upon the back face of this sleeve are clutch projections 53, which are adapted to engage projections 50 upon the belt-pulley. Sleeve 51 is provided with a groove, (not clearly shown,) in which are half-collars 54. (See Fig. 2.)

is a lever pivoted to an arm 56, proj ecting backward from the front bracket 26. The upper end of this lever is bifurcated, and the arms are secured to half-collars 54 by bolts or pins 57.

53 is a link, one end of which passes through the front bracket 26 and is pivoted to the lower end of lever 55, the front end thereof being pivoted to operatingdever 44 at a dis tance above its pivotal point to ears 45. The operation of this mechanism will be clearly understood from Fig. 2. It will be seen that when operating-lever 44 is moved toward the left the rear ends of the clamping-arms will be raised, which will press the clamping-surfaces down upon a hat-body on the cone, thereby holding it firmly in position. This movement of the operating-lever will also draw the lower end of lever 55 toward the left, which will throw the upper end thereof toward the right, and will force the two sets of clutch projections 50 and 53 into engagement, as shown in Fig. 2, thereby communieating the rotary movement of belt-pulley 49 to the spindle. The belt by which motion is imparted to belt-pulley 49 and the spindle extends from a suitable main or counter shaft. Neither shaft nor belt is deemed to require illustration. It will be noticed that the beltpulley is made long enough so that in the longitudinal movements of the carriage and parts carried thereby said belt merely hasto slip along said pulley, its actual position being the same at all times.

59 denotes the brush, which is constructed in substantially the same manner as in our former patents, Nos. 361,073 and 396,829, the essential principle being a hollow shaft or spindle through which the stiffenin g material is supplied to the brush. This brush is fully described and claimed in our said patent, No. 361,073, and therefore is not thought to require description in detail, the operation of the brush itself being the same as in that patent. In the present machine the brush, shaft, and tank are supported by an extension 60, which is bolted rigidly to the bed.

61 denotes the hollow shaft by which the brush is carried and by which the stiffening material is supplied thereto,,said shaft being journaled in boxes 62 upon standards 63.

64 denotes the tank for the stiffening material, which is supported by one of said standards and is connected to the shaft bya suitable union 65, a cook 66 being provided to cut off the flow of stiffening material from the brush when not in use. Motion is imparted to shaft. 61 by means of a belt (not shown) extending over a pulley 67 on said shaft.

It will of course be understood that machines of this class are required to operate upon different sizes, qualities, and thicknesses of hat-bodies. \Ve have, therefore, in our present machine provided adjustments for the various parts to adapt it to all classes of work.

The two principal standards by which shaft 61 is supported are shown as made integral with an upper plate 68, which is secured to an intermediate plate 69 by set-screws 70,

one of which passes through a curved slot 72 in plate 68, so as to permit said plate, to gether with the shaft and brush, to be oscillated upon plate 69. This is in order to permit the hollow shaft and the brush to be adjusted in a position other than parallel to the spindle carrying the cone, so that any desired contact may be secured between the brush and the hat-body upon the cone, it being of course understood that the cones necessarily IOC IIO

vary in size considerably in changing from one style of hat to another. Having secured the necessary adjustment, plate 68 and the parts carried thereby are rigidly locked to plate 69 by tightening up the set-screws. Under plate 69 is a lower plate 73.

74 denotes grooves or ways in the sides of plate 69, which are engaged by ribs 7 5, which project inward from plates 70, bolted to the sides of plate 73. Upon the under side of plate 69 is a ing '77, which is engaged by a quick thread (not shown) at the inner end of a rod 78, which extends to the front of the machine and is provided with a hand-wheel 79 for convenience in operation. It will be seen that by turning rod '78 through the engagement of the screw-thread thereon with lug '77 plates 68 and 69 will be moved toward the right or left, as may be. This adjustment enables us to vary the position of the brush longitudinally to the cone. Upon the under side of plate 73 is a rib 80, which engages a corresponding groove in the upper side of extension (50. (See Fi 3.) 81 is a lug also extending downward from plate 73, which is engaged by a quick thread (not shown) upon the inner end of a rod 82. (See dotted lines in Fig. 4-.) At the outer end of this rod is a hand-wheel S3 for convenience in operation. By turning this hand-wheel toward the right or left, as may be, we are enabled to move the lower, intermediate, and upper plates and all the parts carried thereby inward or outward relatively to the cone.

M denotes an extension which is rigidly bolted to plate 68. At the forward end of this extension is one of the standards 63, by which the hollow shaft is supported. 85 is a bracket on the under side thereof, which supports the forward end of rod 78. 8G is a dovetail slide fitted in corresponding ways in extension Si and adapted to move transversely to said extension. A. lug 87, projecting upward from said slide through a slot 88 in the extension, is engaged by a threaded rod 89,whieh is held against endwise movement, as clearly shown, and is provided with a hand-wheel 90 for convenience in operation.

It will be apparent that in order to stiffen a hat-body it is necessary to swing the cone with the body thereon inward into contact with the stiffening-brush. )Ve have already explained the construction and arrangement of the cone, spindle, turning plate, the.

91 is an operating handlc rigidly secured to any suitable portion of the turning plate, near the forward portion thereof. When the operator desired to place a hat-body in contact with the stifl.ening-brush, he seizes this handle and swings the turning plate, cone, 820., into the desired position. At the forward end of the turning plate an anti-friction roller 92, which is adapted to engage a suitable stop-plate 93 to detern'iine the inward movement of the turning plate, cone, (be. The operative face of this plate is preferably provided. with. a steel strip 94 and with a slight incline 95, the action of which, when roller92 rides down it, is to throw the extreme tip of the hat-body closely against the brush, so that the tip will become thoroughly stiffened, as is fully explained in our former patent, No. 396,829. Stop-plate 93 is connected to slide 86 by means of set-screws 96, one of which passes through a curved slot 97 in the stopplate, so as to permit thelatter to oscillate upon the slide. This construction is clearly shown in the inverted plan View Fig. 5. )Vhen it is desired to adjust the stop-plate to change the position of the cone and hat-body relatively to the brush when the cone is thrown to its extreme inward position, it is accomplished by turning hand-wheel 90 in either direction, as may be required; and should it be required to change the position of the stop-plate by oscillating it in the horizontal plane, this may be accomplished by loosening set-screws 96, turning the stop-plate to the desired position, and then looking it by tightening up the set-screws.

98 denotes a trough placed under the stiffening-brush,which is provided with a scraperplate 99, with which the bristles of the sizing-brush come in contact in use. The ac tion of this scraper is to remove surplus sizing material from the brush, thereby preventing spatter-ing and waste of the sizing material, and also preventing the sizing ma terial. from being deposited upon the hatbody faster than it can be absorbed thereby. A drainage'pipe 100 leads out of the trough, and the surplus sizing material which passes out from the trough is caught in a suitable receptacle (not shown) placed beneath. This trough is supported by a bracket 101, which is rigidly bolted to extension 84:. The trough is secured to the bracket by means of a lug 102, which is pivoted between ears 103 on the bracket.

104c denotes adjusting-screws, which pass up through the bracket and engage the opposite ends of the trough. By turning these screws upward. or downward, as may be required, the trough may be tilted so as to cause either end of the scraper-plate to engage more or less positively with the brush. This arrangement enables us to graduate the quantity of sizing material applied to different portions of the hat'body. For instance, a greater quantity maybe applied at the lower portion of the body than at the tip, or vice versa.

It will be seen that .by adjusting the trough at an angle the quantity of sizing material deposited upon a hat-body may be made to increase or decrease gradually in any direction, this being an important feature in stiffening certain grades of hats.
