CAMERA.

Application filed .Tu 1y 29, 1916.

To all 107mm it may concern.'

.lie it known that ne, (laut llonNMaNN and ,lil/,im (nl. (linnn, both citizens ot the United States, and both 'residents of the city of Binghamton, county ot Broome, and State ot New York, have, invented certain new and useful lnilirovements in (lameras, of which the following is a specification reference beurer had drawings.

This invention is an improvement upon that tor which we liled application t'or `lietfters Patent ot the United States December 1i', 1915, Serial No. 137,31-l, to which we reter for a more complete disclosure ot' the details ot etnstruction and operation of the mechanism other than that immediately involved in this invention.

The purpose of this 7 to the aeeoniiunrving present invention, the

saine as that oi.' the former one, is tofprof vide a camera with means whereby the teeding` of the iih'n :t'or making successive exposures may be automatic and yet under the perfect control o1 the operator, whereby great speed in the making oi exposures is possible; and our former apparatus was provided, among other'things, with an indicator which disclosel the number otl exposures that had been Inadeon any given lihn and`eonsequently the amount of unexposed lm yet available to the operator for additional exposures; but that. index was operated solely by the motor and only when it effected the inoven'ient of the lilm, so that if the operator at any time desired to make an exposure by hand, then inasmuch as the indicator wasl only operated when the motor was used, there was of course no record produced oi such hand made eX- posure; consequently if the operator forgot to advance the4 indicator correspondingly with the number ot his hand made expo sures, then the indicator instead ot being,r a guide correctly notifying the operator of the condition of his apparatus, might become ail'irn'iatively misleading, resulting in faulty, it not valueless exposures.

lt. is the purpose oi' this present invention therefore to equip an apparatus ot the classl statedwith parts soconstructcd and Patented Feb. 20, 191.?. serial No. 111,981.

associated together that the' indicator will properly recordl any exposure, whether efieeted through the instrumentalit)r of the motor or b v hand, thus under all cireumstances serving' as a safe guide to the operator.

bReferring; to the drawings, Figure 1 is an elevation Qt the side ot a. folding camera embodyingk our invention` the cover plate which wiltordinaril7 protect the mechanism being;` removed; Fig. i is a vertical sectional view, soi-ne ot'the parts being` shown in elevation, taken on the line 1`-1 of Fig. 1; Fig. 3 is a longitudinal detail partly in elevation showing the parts more immediately involved in this invention.

.ln the drawings, l. represents the body of the camera, 2 the removable back, 3 one ol the supports tor the usual carrying handle, at the windingl spool, 5 the deliveryspool, the spindle for the wintling` spool, 7 the knurled thunibnut on the end of the spindle 6 whereby it may be conveniently turned by hand, 8 the motor, in this Case a spring', as fully explained in said application. t) the shaft tor the motor, 10 the pinion on the end ot' the shaft, it being,r the main driving;` rear of the apparatus, 11 the trip piner lever whereby the motor is released and stopped. 12 the ehain ot gearing, 13 the. escapemeut. Il the vibrator. 'l`hese last two parts ditl'er slightly troni the construction shown in said pending' application but their functions are the upon which we ot gearing'.

ln our said previous invention the indicator plate ,was placed at the lower end of the chain of gearing und was actuated step by step by a pawl connected with and oper ated by the level 11, so that it that lever was not moved, which would be the case it' the winding spool was actuated by hand instead ot' by the motor, then there would be no movement of the indicator disk, hefiee one or more exposures .wonld have been. made without any record thereinv Under this present construction therefore we trans pose the indicator trom the lower or tail end of the chain ot' gearing to or near t0 the same. 1ro-is the base plate preter to support the chain i opposite end and supplement it by added parts which will now lows: i 4

As stated above, 6 is the center for the winding spool. lts construction and method of operation are now so well understood as not to require explanation. 7 is the knurled thumbnut on its exposed outer end whereby it may be turned by hand. 1G is a. small pinion mounted on and which turns with the spindle 6, and it gears into a larger gear 17, which is loosely mounted on the axis 1S of the larger gear 19, which is driven by the pinion 20, which latter is preferably integral lwith it, by the main driving gear 10 on the motor shaft. The axis 18 is pre. ierably supported upon the base plate by the threaded extension Q1 thereof.

22 and 23 are mere spacing washers lo cated between the gears. 24 is a gear on` the center 6 whereby, as explained in said application, the take-up spool is rotated when the motor is employed. 25 is the index plate. 1t is provided, as seen best in Fig. l, with a series of numerals, in the present instance y1 to 12. Other designations and of any desired number may be employed.

The index plate be described, as foly upon the outer surface f the gear 17in located between the gear motor 'is used motor is usedfall such manner that it may be turned thereon. We prefer to employ spring fingers 26 17 and the dial plate and so arranged in any known way that'the dial plate'will be frictionally held on the gear. "We also provide the dial plate with a raised'web or linger plate 27 whereby it may be conveniently turned. The spring friction iingers 26 may, if desired, be attached to the gear 17 and so shaped that they wiil take i the necessary frictional bearing 28 is a washer or equivalent device which holds the gear 1G in The operation is obvious. "When the its driving pinion l0 will rotate the pinion 2.0 and tbc lai-gc gear 19, which integral with the latter, and it in turn will rotate the gear 2li and through it 'the spindle of the take-up spool, to which it is connected, in the manner explained in said pending application, whereby the spindle may be rotated by hand without rotating 'she chain rolia gearing, so that when the two gearsi and Q4 will likewise rotate, that is to say; the washers Q2 and 23, the gears 16 and 1 7, the dial plate and the knurl'ed tbumbnutfl, will all simultaneously rotatev tov the extent that they are driven by the,`

n'iotor. lNhen, however, it is desired to turn tnewinding spool, either for the purpose of making an eA )sure or otherwise, thenby ump ue-6 and-tbe winding spool.

Apeculiar 25 is suitably supported parts associated with these ii'ion of the knurled thumbconnected with it. will be rotated in the G5 same direction as before, but owing to the connection between the gear Q4 and the spindle there will be no rotation ol' the chain of gearing. but the gear lli. which is rast upon the spindle (i, and through it the F gear 17 carrying the dial plate 25 with it, because oic the frictionalconnection between the two, will be rotated, so that the dial plate will properly register the number oi expolsures made, whether the take-np spool has been operated by the motor or by hand, and

thus a correct record will be made whereby the operator may know with assurance the position oil` his libn.

It will be. obvious to those who are familiar with such mat-ters that modifications may be made in the details of construction and to' some extent their method o'l combination and yet the essentials of the inventionv be retained. le therefore do not limit ourselves to that which we have herein dcs'cribed and illustrated which shows one form only in which our invention may be constructed. i i
