J. B'. BLAIR, OF PHILADELPHIA, PENNSYLVANIA.

PHOTOGPtAPHlC-CAPLD PRESS.

Specification forming part of Letters Patent No. 43,083. datc(lJ\.ne14, 18045 antcdatcd May 24, 1564.

To all whom it may concern,.-

Beit known that l, J. B. BLAIR, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Photograph-Gard Presses 5 and Ido hereby l declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view, and Fig. 2 a vertical transverse section, of one of the said improved presses.

Like letters of reference indicate the same" parts when in both figures.

The nature of my invention consists, substantially as hereinafter described and specined, rst, in the employment, in a photographcard press, ot' a polish ed-metal roller of a small or reduced diameter between two smooth-metal rollers of much larger diameters in such a manner that while the small polishing-roller is in contact with the card under operation, one of the two larger rollers supports the said card, and the other prevents the small roller from springing, for the purpose of polishing the cards in a more perfect and expeditious manner and with the expenditure of much less motive power 5 second, in the application to photograph-card presses of a deiiector constructed to operate substantially as hereinafter described, for the purpose of reducing the curve or straightening cord, flattening the card as the same is delivered by the rollers; third, in sustaining in a self-adjusting manner the supporter of the pillow-blocks of the journals of the card-supporting roller by resting its center brought to an edge or point for the purpose upon an adjustable base, so that it will vibrate thereon, for the purpose of producing anti-keeping up parallelism of the rollers in relation to each other in a more expeditious and perfect manner5 and, fourth, in the employment of a hand-wheel upon the journal of the cardsuppoiting roller, as hereinafter described and specied, for the purpose of dispensing with the use of the gear-wheels heretofore required in roller-presses to compel the card to enter between the rollers.

In the drawings, A B is the frame of the press5 C, the small polishing roller 5 D, the card-supporting roller 5 E, the roller which ,l supports the polishing-roller during the passage of a card beneath it; Il', the deticctor5 Gr, the self-adjusting pillow-block supporter; G', an adjustable base for the saine, and H the hand-whcel.

The frame A B consists ot two slotted castiron standards, a a', provided with feet, and bolted together permanently, so as to be parallel with each other. The rollers I) -and E are smoothly-turned cylinders of castiron, each being aboutv an inch and a quarter in diameter, (more or less,) and having a suitable'journal at each of their ends. The polishingroller C is a smoothly-polished cylinder of steel, about halt' an inch in diameter, and provided with suitable journals, onel of which, c, projects sufficiently far through the frame A B to receive upon it a suitable crank-handle. (Not shown in the drawings.) rlhe upper roller, E, in this instance is not adjustable, while the card-supporting roller D rests in pillowbloclrs g2 g2 which are attached to the selfadjusting cast-iron supporterG. The under side of this supporter G is inthe form ot' an obtuse angular edge, g, and in this instance rests with its said edge directly upon the base-piece G, the latter bethe vertical thumbscrews I I. The polishingroller C rests with its face upon the face of the card-supporting roller l), its pillowblocks c2 c2 being titted to slide up and down freely and accurately in the slots of the standards c c of the frame A B. The detiector F is made of metal, in the form of a square frame, and supported by and so as to vibrate freely upon the journals of the polishing'- roller C. The side upon which the cards are placed to enter between the rollers has a platform,]", for the purpose, while the under and inner portions of its opposite side are rounded and smoothed opposite to the surface of the roller D, (seef, Fig. 2,) so that as the card is discharged on that side by the said rollers it will pass in contact with the said rounded, smooth edge or side f3 of the same, substantially as indicated by the faint line in the same figure. This detiector F is adjusted in height by means ofthe downward pressure of a vertical thumb-screw, f4, (sec Fig. 1,) and the platform f', being the heavier side of the frame, the lat-ter can be instantly fixed bythe ing supported adjustably upon the ends of screw f1l so as to give any degree of counter curvevv to the card as the latter passes under it that may be required.` The handwheel H is iXed upon one of the journals of the cardsnpporting roller D,- (see Fig. 1,) and therefore a slight rotary movement can be given to the latter thereby for the purpose of compel' ling the card to enter between the rollers C and D. The hand-wheel may be placed upon one of the journals of the polishing-roller C, (as lrepresented in Fig. 2,) thus dispensing with the crank-handle and using gear-wheels to connect the rollers; but the lirst-described arrangement is cheaper and produces a more uniform or ,even polish upon the card.

Operation: The rollers C and D having been adjusted for the reception and pressure ot' the card between them by means of one or both of the thumb-screws I I, and the detlector F also adjusted so that the card will be compelled to pass out in contact with the smooth, rounded under edge, f3, of the same, the operator gives motion to the roller C by means of the crank-handle, places the card on the platform of the deflector F, and, pushing it up close between the rollers C and D on that side, he then gives a slight opposite rotary movement tothe roller D, and thus causes the card to be instantly taken in between the said rollers, and, passing onward, it comes in contact with and is bent downward by the rounded edge f3 of the deflector, and if the latter has been properly adjusted, the degree of counter delection produced thereby will exactly correct the upward curve, (sce dotted faint lille in Fig. 2,) which the small polishing-roller C tends to produce in the card, and thus deliver the card, evenly polished, in a perfectly straight or dat state.

It will readily be seen that as the polishingioller G is quite small in comparison with the card-supporting roller D the hand-power necessary to be applied to the crank-handle to produce the requisitely-strong pressure upon the card will be very slight; that the operation of polishing or pressing can therefore be effected with greater ease, facility, and perfection, and without any liability of the ypolishing-rollers springing away from the card; that the cards will be delivered by the machine in a perfectly-flat state; that the required parallelism of the rollers will always be maintained during the operation ot' the machine, and that gear-wheels are entirely dispensed with by the application ofthe handwheel to the card-roller, as described, and shown in Fig. 1.

I wish it to be understood that I do not desire to confine myself to the use of only one small polishing-roller, G, as it is obvious that two such rollers may be supported together for receiving the cards between them, theyl being, of course, sustained by the larger rollers, D and E 5 but I nd a single small roller, C, quite sufficient for the purpose.

Having thus fully described my improvement and pointed ont its utility, what I claim as new therein, of my invention, and desire to secure by Letters Patents, is-

1. The employment, in a` photograph-card press, of a small polishing-roller, (l, between two larger sustaining-rollers, D and E, the three being arranged so as to operate together substantially in the manner described, for the purposes specied. v

2. The application to a photograph -card press of the adjustable deflector F, the same being constructed and applied so as to operate upon the cards substantially in the manner set forth and described, for the purpose specified. Y v

3. Sustaining the pillow-blocks of the rollers of a photographcard press by means of an angular supporter, G, constructed and applied so as to rest with its angular bottoni edge, g3, only upon an adjustable base of any suitable kind, which will permit it to vibrate thereon, so as to adapt itself to the rollers, as

vdescribed and set forth, for the purpose specitied.

4. The employment of a handwheel, H, applied to the card-supporting roller, as described, and shown in Fig. 1, for the purposeJ specified.
