Letters Patent No. 65,926, dated. June 18, 1867.

IMPROVEMENT IN 4liliAClINl POR GOATING HATS.

TO ALL WHOM'IT MAY CONCERN:

Be it known that we, JULES Fnnrvcors Marinas and Diisrn: MATHURIN Lncar, of Paris, France, have invented a new and improved Machine for Manufacturing Sham Beaver Hats, and similar articles, and which we call a Pulvi-Feltering Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification,

This invention relates to a cert-ain machine for coating` hats or hat-frames with a powder of fur, wool, or other substance. The hat or frame to bc'coated is laid on an elastic support, and coated, powdered, and dried on both sides without its being necessary to lay hands on its surface u ntil nished. We take a certain number of hat-frames previously coated withsome glutinous substance, place them on suitable frames, and secure them to a shaft of peculiar form passing horizontally through a closed chamber. This shaft rotates and recprocates, and thus imparts to the framesa slow rotary mot-ion, and at the same time a rapid rocking or reciprocating motion, so that the inner and outer' surfaces of the hat-frames will be presented to the action of a strong continuous current of foltering powder, in order to be, by a single operation, completely and appropriately coated. The continuous current of feltering powder is produced by special fan, provided with screws, moving in the closed chamber.

The annexed drawings, and a description of all the parts constituting our machine, will make our invention better understood. Figure 1 is a vertical longitudinal sectional view of our machine through :v fig. L

AFigure 2 is a cross-sectional view of the same.

Similar letters of reference indicate like parts.

A is a chamber in which are placed the hat-frames tov ber isitted with panels, which will be hereinafter described, some of' which are stationary and others movable at will. The two extremeends of the framing are intended to hold the bearing and moving pieces. B is a fan for exhausting the felteringpowder from' the lower part of the chamber A, in order to force it immediately towards the upper part, so as to form a strong endless current in the interior of said chamber. C are screws with equal threads, but inversely inclined on the fan-shaft and each `side of the wings, so as to bring the feltering powder from Vthe lower part of the chamber A tothe inside of the fan-drum, placed partly' inside of the said chamber, and communicating therewith through the two openings formed laterally and opposite to the screws. D is'the shaft of the fan or ventilator and its screws. l E and E are pulleys fixed on sa'rdshaft D for receiving and imparting motions. F is the force-condnit of the fan, and G the swan-neck establishing communication between the conduit F and the chamber A, and terminates in a long slot, r, through which cornes with great rapidity the feltering powder forced in by the fan. H is a horizontal and I a counter-shaft imparting, by means of pinion M on I, and L on H, rotary motion to shaft H, and consequently tc the hollow shaftfK, which carries the hat-holders. The shaft, KV surrounds the shaft H, and is held concentrically with that shaft by means of springs R, which are secured to projectionsS on H, and S on K, and in such manner that the shaft K will rotate with the shaft I. i N is a spur-wheel, forming part of a sleeve, pb, which turns loose outheend of shaft H, being actuated by a pinion, O, on shaft d. P is a beating gea-r formed of two toothed couplingboxes p andy', one of which, ip', formed with the spur-wheel N, is loose on the central shaft H, and the other, lo, moves only in a longi tudinal direction ou 'said shaft, so that as theipart 1o is revolved, p will be thrown against the end of lche shaft K, and then moved back by a spring, Q,which continually brings thecoupling-box p /in contact with p. T represents one of three arms-affixed to the coupling-boxp of the beater P, so `as to communicate the shocks of the i latter to the hollow shaft K in hitting the projection t formed on the end of said hollow shaft. The intensity of the shocks may be regulated by compressing more or less the spring Q, between the end of shaft K and the coupling-box p of the beater. U are screw-handles serving to fix the arms T-cn the coupling-box p, and to cause the central shaft to turn with the hollow one for more readily fixing thereto or withdrawing therefrom the hats, all the straps being on the locse'pulley's. V and V are pulleys xed on the countereshaft I for receiving and imparting motion. X and X' arepulleys fixed on the counter-shaft T for receiving and imparting motion. Y

be coated. The framing forming the sides of the cham-l are supports for shafts I'and J. Z are flexible' three-branched supports, terminating in fixed points for fixing thereto the hat-framesiand secured in loops ct fixed on the hollow shaft, as shown. b is a movable panel, forming a door, hinged on its lower edge. c e are panels, that may be taken out to facilitate access to the chamber. e-is a partition-valve, oscillating around its axis o for directing the current of feltering powder through the swan-neck conduit on the hats, or into the passagef, in order to expel the powder from the chamber when the colors are to be changed, said valve bcingopened or closed by a rod, lr. At the end ot' the passage f is hung a bag, which allows the air to pass through it, but retains the powder as'it is driven through the passage from the chamber. The openings formed in the partitions or panels for the passage of the shafts are provided with leather washers, rubbing against the shafts so as to prevent leakage.

I will now describe the'working of the machine.

The operator will fix the hat-bodies on the hollow shaft K by introducing the lower paint of each support Z into the projections il, providedwith set-screws for that purpose. He will shut the door b-after throwing into the lower part of the chamber some handfuls of the foltering powder of the desired hue to serve for the whole or part of the days work. He will bring the straps (moving on the loose pulleys) on the fixed pulleys, and the operation of foltering is then going on. The operator then' brings down the straps on the loose pulleys in order to stop the movement of the machine. vHe opens the door b, undoes the screws from the projections i, and withdraws the hats,- care being taken to touch but the supports of the articles, which are then conveyedv to the drying-room, from whence they are taken out for use. The hats may be transferred from the machine to the drying-room by being fixed through said supportsvon a perforated rod, by means of which they are carried. One person is required to work the machine, and two more, either women or boys, for coating the hats which are to feed it. The change of colors is obtained 'by taking from ont the machine the felteririg powder contained therein, and substituting another therefor. To remove the powder -in* the machine it is necessary 'only to fasten a bag at the end of the passage f, and turn the valve to the position shown in red in lig. 1; then set the fan in operation, and the powder will be blown through the passage and into the bag. `It is only when the fan has nothing more to expel that all things are set again in their original state, and that the feltered powder of the desired color is fed into the chamber. i

By this new process hats will be obtained of a notable finish, as the foltering powder, `projected in a regular manner on their surface by a strong continuous current of air, will'impart to them a brightness and suppleness which will, in our opinion, match the true and most genuine beavers.

Having thus described our invention what we claim as new, and desire' to secure by Letters Patent, is 1. A machine for feltering hats, made and operating substantially as herein shown and described. '2. The hollow shaftK, combined and connecting with the sha-ft H by meansof springs R R, substantiallyas herein showa'd described.`

3. The beating apparatus P, in combina-tion with thespring Q, substantially as herein shown andpdescribed. 4. The arrangement of the valve and passage or conduit f, in combination with the channel Fand face B, all made and operating substantially as herein shown and described. I
