ings, so that the same will conform closely to the contour of the inside of the hat or bonnet, thus obviating the necessity for cutting and stitching the material from which the lining is formed and shaping the same by hand to fit the hat.

The invention consists incertain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and embodied in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a machine constructed in.

accordance with the present invention. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged side elevation of the rotatable holder upon which the lining material is placed and held while subjected to the action .of the crimping-rolls. Fig. & is a longitudinal sec tion through the same. Fig. 5 is a detail perspective view of the plate upon which the lining is placed. 'Fig'. 6 is a similar view of the opposingplate, which overlies thelining material. Fig. 7 is a detail perspective view of the eccentrically-movable head upon which the supporting-plate is mounted. Fig. 8 is a plan view of the stationary disk about which the head moves, and Fig. 9' is a perspective view of the hat-lining after the same has been crimped by the improved machine.

ends in bearings 5, located at the upper and lower ends of said guides.

6 designates a cross-head which has its ends reduced and slidingly fitted in the grooves of the guides 3, so that it may move up and down therein, said cross-head being adjusted by turning the rods or shafts at, which have a threaded engagement with the ends of the cross-head or with sleeves or ferrules fitted thereon. The cross-head 6 is provided at or near its center with a cross sleeve or socket 7, through which passes an inclined or oblique shaft 8, having movably fitted upon its lower end one of the crimping-rolls 9, which is preferably convex on its outer surface and milled or provided with corrugations, as indicated at 10, said corrugations meshing with corresponding ribs or corrugations 11 on a concave crimping-roll 12, movably fitted on the end of a horizontal shaft 13. A tension-spring 14 is interposed between a collar 15, fitting loosely around the shaft 8 and seated in an annular groove therein, and

one of the guides 3 or a cross-bar connecting saidguides, as may be most convenient, the tension of said spring being exerted to preserve the proper engagement between the crimping-rolls, while the corrugations of said rolls may be adjusted into proper mesh with each other by raising or lowering the crosshead 6.

. 14 indicates a pendent rod which connects pivotally with the upper end of the shaft 8 and at its lower end with a lever fulcrumed on one of the standards 2.. By rocking said lever the upper roll 9 may be lifted out of contact with the lower roll for introducing or removing the lining material. The'shaft 13 is hollow and the rear end of said shaft receives the discharge end of a Siamese pipe 16, which conveys gas and air to said shaft and through the same into the crimping-roll 11, which is hollow and forms a combustion-chamber in which the gas is ignited for heating said roll to the desired temperature. The lining material is sized with any suitable agent upon one surface, and when subjected to the action of the crimping-rolls the flutes or crimps made therein are rendered more permanent than would be the case were such material simply passed between cold rolls. The rolls 9 and 12 are provided at their inner and outer edges, either or both, with matching annular beads 17 and grooves 18, whereby the lining material is beaded at the inner or outer portions of the crimps or at both ends, thereof as may be preferred.

l9 designates the supporting-plate for the lining material, said plate being substantially elliptical in plan View and provided with depressed sockets 20, in which are fitted pieces of cork or other soft material to receive the depending points or spurs 21 of an upper opposing elliptical plate 22, adapted to be placed on the lining material, so that the pins or spurs will pass therethrough into the lower plate, the upper plate being provided with a finger-hold or handle by means of which it may be removed and replaced. Secured to the under side of the supporting-plate 19 is a head El, having spaced arms 25, by which it is secured to the plate 19, and having spaced depending flanges 26, the purpose of which will appear. 27 represents a stationary disk upon which said head is mounted, and this disk is provided with a radial slot 28, up through which projects a pin or stud 29, fast on one end of aslide-bar 30, mounted in a grooved guide 31, secured to and supported upon the bed-plate in any convenient manner. The pin or stud projects above the upper surface of the disk 27 and enters a slot 32 in the body portion of the head, said slot 32 extending transversely of the elliptical supporting-plate 19.

33 designates a pair of keeper-plates which are secured to the bottom of the depending flanges of the bearing-head, said plates being extended under the stationary disk and serving to prevent the displacement of the bearing-head from said disk as the supportingplate is revolved.

By means of the construction just described the supporting-plate 19 when revolved will have an eccentric motion, so that the edge which lies adjacent to the crimping-rolls will be maintained at the same distance therefrom, thus enabling the crimping-rolls to operate upon and flute the projecting edge of the lining material in an elliptical path. This eccentric motion is caused by the cooperation of the stud 29 with the slot in the bearing-head. \Vhere it is desired to substitute a supporting-plate 19 of different size or shape, the said stud may be adjusted lengthwise of the slot in the stationary disk by moving the slidebar 30. The outer end of the slide-bar is provided with a longitudinal slot 35, through which passes a screw 36, said screw entering the guide in which the slot is mounted.

37 designates a washer which is interposed between the head of the screw and the slidebar, and which is provided with a depending portion 38, entering the slot in the slide-bar, and also with an upturned portion 39 at the opposite end of the head of the screw. By loosening this screw the slide may be adjusted for changing the position of the pin or stud at the opposite end of said bar.

The piece of material from which the hatlining is to be formed is engaged between the elliptical plates above described, and the upper crimping-roll is lifted to admit the marginal edge of the lining between the rolls. The machine is now actuated either by hand or some suitable motor, thus causing the crimping-rolls to grip the lining material, and as the material feeds between the rolls the supporting-plate is revolved, and by reason of its eccentric movement the edge of the supporting-plate is kept at a uniform distance from the rolls, thus crimping the lining material in elliptical form, as shown in the drawings. This rolls the marginal edge of the lining over, as shown in the drawings, and adapts it to conform closely to the inside contour of the hat. Any desired fabric or soft material may be employed in the manufacture of the hat-lining and will be crimped with uniform success by the machine above described.

It will be understood that several parts of the machine are susceptible of changes in the form, proportion, and minor details of construction, which may accordingly be resorted to without departing from the spirit or sacrificin g any of the advantages of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is
