HAT-POUNCING MACHINE.

SPECIFCATION forming part of Letters Patent No. 691,018, dated January 14, 1902. Application led September 10, 1901. Serial No. 74,931. (No model.)

To all whom it may concern.-

Be it known that I, CLEMENT MARIE T1- RARD, a citizen of the Republic of France, and a resident of 11 Rue Grange Batelire, Paris, France, (whose postolce address is as above,) have invented certain new and useful Improvements in Hat-Pouncing Machines, of which the following is a specification.

This invention relates to improvements in hat-pouncing machines, andhas for its object to provide improved mechanism for pumicing or glass-papering the same, commonly termed pouncing In theaccompanying drawings, Figure 1 is a plan view ot' the mechanism as a whole at the moment of the commencement of the operation of pouncing a hat. Fig. 2 is a front elevation of the mechanism at another phase in the operation. Fig. 3 is a corresponding plan view. Fig. et is a side elevation of the same mechanism at the termination ofthe pouncing operation. Fig. 5 is a corresponding plan view. Fig. 6 is a detail view ofthe pouncing member and of its operating mechanism, and Fig. 7 is a front elevation of this pouncing member.

My improved machine comprises, essentially, apouncing member operated by means of an appropriate motor imparting to it a movement adapted to suitably effect the friction upon the surface of the hat under conditions resembling those of handwerk, and this pouncing member, provided with its own driving mechanism, is guided by other mechanism, so that it passes over every point of the surface of the hat, to which a movement of rotation is imparted.

The hat 1 is mounted upon a finishing-form 2 in the manner usual in all hat-linishing machines, and this form 2 is rotated in such a manner that notwithstanding the shape of the hat this latter always rotates circularly with respect to the point at which it is in contact with the pouncing member. Brieliy, the operating device is similar to that employed in lathes forturning oval objects. With this object the nishing-form 2 is rigidly connected to a shaft et by means of suitable catches This shaft is rigidly connected to a slide 5, mounted in a slideway 6, fixed to the driving-shaft 7, by means of which the motive power is transmitted. The lateral edges of the slide' are in contact with a fixed circular way 8, mounted upon the general framework and which is eccentric with respect to the driving-shaft 7, which latter is operated by suitable transmission-gear 9.

The pouncing member consists of a support 10,upon which is arranged the sheet of pouncing material ll-such as glass, paper, or linen, for example-its surface being slightly convex. Between the sheet of pouncing material and its support 10 a sheet ot' felt or similar material is interposed. rlhe support 10 is rigidly connected with a plate 12, mounted upon two eccentrics 13 14, of which the aXes 15 16 are journaled in the wall17 of a box or frame 13. Upon the axes 15 and 16 are rigidly fixed two pinions 19 and 20, connected by means of an intermediate pinion 21. In addition to the pinion 2O the axis 16 carries a second pinion 22, meshing with the pinion 23 of a small electric motor 21. It follows from this arrangement that when the electric motor 24 is operative the pouncing member 10 assumes a movement such that each of its points describes a small circle owing to its eccentric driving. It should be noticed that the sheet of glass paper or the like 11 is mounted by means of a fiat spring 25, maintained in lugs 26, mounted upon the support 10. The whole device, constituted bythe pouncing member and its motor mounted upon the box-frame 18, is fitted into a fork 27, provided with a suitable handle 28. This fork 27'is rigidly connected to an aXis 29, running on ball-bearings in a sleeve 30, adjustably attached to a base 31, to which latter is pivoted a second fork 32, which is also journaled upon a shaft 33 and terminates in a handle 34. The fork 27 is mounted in its sleeve in such a manner as to render the point of attachment of the frame eccentric to the axis 29, and thus regulate the position of the frame by reason of its own weight. The second fork 32 is provided with a part 35, comprising two projections 36, serving for the reception of a shaft 37, to one of the extremities of which is fixed an arm 33, while its other extremity is provided with a pawl 39. Upon the said shaft 37 and between the two projections 36 is engaged a spiral spring 40. The part 35 is also provided upon its lower face with a ring 41, to which is attached a counterweight 4:2.

IOS

The connection between the pouncing device and the driving-shaft is effected in the following manner: The shaft 35 is mounted in a fork 43, rigidly connected with a plate .44, carrying a socket 45. Upon this plate 44 is fixed another plate 46, to which is attached a connecting-rod 47, which is journaled upon a toothed wheel 48. This latter is mounted loose upon a cylindrical hub 49, carrying a shaft 50, which is journaled upon the general framework. The point upon which the 'toothed wheel 48 is mounted is eccentric with respect to the shaft 50. To the hub 49 is fixed a handle 5l, by means of which it may be rotated. Upon the framework of the machine and beneath the handle 5l is arranged a flat spring 52 in the form of the arc of a circle, which comprises a stop-notch 53, serving to maintain the said handle 51 in a predetermined position. The gear-wheel 48 is provided upon its lower face with a projection 54, adapted to come into contact with the spring 52. In addition to the handle 51 the hub49 is provided with an arm 55, to which is attached a counterweight 56. The connecting-rod 47 carries a stud 57, adapted to act upon a sector 58, mounted upon an axis 59, the extremity of which is adapted to come in contact with the arm 38. The gearwheel 48 is in engagement with a pinion 6l, rigidly connected with a pinion 62, which meshes with a gear-wheel 63, xed to a shaft 64, driven from the shaft' by means ofscrew transmission 65.

The operation of this mechanism is as follows: In the first place it should be remembered that the pouncing member receives from its electric motor a movement which, as above stated, reproduces that of hand-pouncing, but which ismore uniform. It is therefore necessary to cause this member to pass over all points in the surface of the hat, and this is what the mechanism above described effects. It has also been pointed out that lthere is imparted to the hat a movement of rotation such that notwithstanding its oval shape it always rotates circularly with respect to the, pouncing member. The pouncing member as a-whole is balanced by means of a counterweight 42, whereby the pressure of this part upon the hat may be regulated as desired. The operation of the pouncing member upon the hat consists, independently of the movement imparted to the part itself by means of its electric motor, of a travel over the surface of the hat, comprising a forward travel and a return travel. When the hat has been placed upon the form, the pouncingfmember is engaged by means of the handle 28 with the part 35 by the intermediary of the pawl 39. The eccentric hub 49 is then displaced by means of the handle 51, so as to cause the gear-wheel 48 to engage with the pinion 6l, and consequently with the driving-shaft 7. Fig. l represents the apparatus in this condition. The machine having been started, the pouncing member is displaced slowly in the direction of the arrow along a generating line of the hat. The pouncing member is thusbrought to the brim of the hat, Fig. 3. Then owing to the movement of the connecting-rod 47, actuated by the gear-wheel 48, the pouncing member returns in the direction of the arrow y, but passes beyond the point from which it started and proceeds to the axis of the hat. The object of this peculiar operation is that the pouncing member may not pass more than once over the top of the hat. This peculiarity is only due to special adjustment, and it is of course possible by adjustment of the connecting-rod 47 and of the plate 46 to cause the pouncing member to start from any desired point of the hat. IVhen the pouncing member has completed its return travel, the connection with the driving-shaft is interrupted and the pouncing member is separated from the hat, while at the same moment the electric motor stops. This cessation of the operation is effected in the following manner: Shortly before the complete revolution of the gear-wheel 48 the stud 57 of the connecting-rod 47 acts upon'one end of a pivoted lever 58, pivotcd to the plate 46 at 59. (See Fig. 5.) The other end of this lever 58 has a hooked end 60, which bears against the arm 38 below its point of pivot to the shaft 35, and thus throws its upper end, with its shaft 37 and catch 39, out, disengaging the catch from the part 31 and allowing the pouncing apparatus to fall backward into the position shown in Fig. 4 by its own Weight. The spring 40 returns the catch to its normal position when the lever 58 is released. Figs. 6 and 7 best illustrate the catch mechanism detached from the forks 43,which by reason of the overhang of this group of parts causes the device to separate from the hat and assume the position represented in Figs. 4 and 5. The projection 54 of the gearwheel 48 then acts upon the spring 52, re-v leases the handle 5l and the hub 49 by reason. of its eccentricity with respect to the gear-wheel 48 and of the rotation of this latter, and rotates until this gear-wheel 48 is disengaged from the pinion 6l, whereupon the operation ceases. The treatment of the hat is then completed. The duration of this operation may be regulated at will by the ratio of the pinions 6i and 63. At the same time that the operation of the device ceases the electric motor stops. In order to produce this result, there is arranged at a suitable point upon the machine an interrupter,which automatically closes the circuit when the machine is started and opens itwhen the machine is stopped.

I may of course introduce into my machine many constructional modifications whereby its essential characteristics are not altered. As regards the pouncing member I would point out that I do not wish to confine myself to its operation by means of an electric motor. I have indicated this method of actua- IOO IIO

tion because it is the most practical; but it is obvious that other methods may be employed-such, for example, as a small compressed-airmachine. I would also state that this pouncing member may be employed with any kind of mechanism other than that above described which is adapted to causeit topass over the entire surface of a hat.
