HENRICH HBSGEER, OF NEW YURK, N. Y., ASSIGNOR 0F ONE-HALF TO E. C. N EELSEN, 0F

. NEW YORK, N. Y.

rneroennrnrc nrrannrns.

To all `whom it may concern:

Be it known that l, HEINRICH Hnsor-nrn, a subject of the Emperor of Germany, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Photographic Apparatus, of which the following is a specification.

The object of my invention is to provide a portable camera attachment of very small size which can be conveniently carried about and attached to any ordinary camera, and set and timed to operate automatically in connection with an adjustable time-exposure mechanism, whereby the photograp may take either an instantaneous or timeex osure picture of himself or other objects.

l, ith these ends in view my invention consists in the peculiar features and combinations of ,parts more fully described Ahereinafter and pointed out in the claims.

In the accompanying drawings, Figure 1 is a general view of my invention as a lied to the shutter of an ordinary camera; ig. 2, a front view of my complete device ready for action; Fig. 3, a side elevation of the plate carrying the alarm and time-exposure mechanisms; Fig. 4 is a front elevation of In complete invention with lthe `face remove the mechanism being set for taking a picture; Fig. 5 is the face on which are located the winders, dials and pointers. Fig. 6 is a front elevation, with the face removed, showing the power mechanism sprung and in action and the position of the parts resulting therefrom. Dotted lines show the closin mechanism released to cl se the shutter; ig. 7, a view showing the po itions of the winders and dials in relat1on to the adjustments shown in the receding view; Fig. `8, a side elevation, partliy in section,.showing most of the parts on the left-hand side of my device; Fig. 9, a detail vie'w of the clutch mechanism yfor throwing the shutter closing mechanism, and Fig. 10, a side elevation, partly in section, showing most ofthe parts on the right-hand side of my device.

This apparatus comprehends three princial organismswhich co crate for performing the three o erations 1n the following order: rst, the tune-mechanism adapted to be set to work for any number of minutes, from 1 to 4, in order to allow am le time forthe photographer to leave the instrument and pose; second, the alarm mechanism which sounds a warning just. before the shutter Speoication of Letters Patent.

o ens and continues during the exposure; t ird, the shutter closing mechanismwinch closes the shutter and stops the alarm.

The clock-work mechanism of my device is mounted on two circular plates la and 1b inclosed within a circular case 1 like that of an ordinary alarm clock. To condense the several mechanisms above described within the space of a small alarm-clock having the form of a short cylinder closed at the ends, is regarded as a ver important feature of my invention,vfor witii device would be too cumbersome and unwieldy for the work of amateurs and others in practicing outdoor or indoor photography. On one side is a face which is provided with the winding handles, dials and pointers.

40 and 41 indicate the handles, and 42 and 43, the dials.

The alarm mechanism, as seen in Fig. 3, consists of a spring actuated gear 2 carryin a pawl and ratchet 2a on a shaft'2b revolve by a coiled fiat spring 2C meshing with pinion 3 iixed to gear 4 which in turn mehses with a pinion 5 on a tripping wheel 6, the radiating arms of which trip the projections 7 and 8 on a hammer 9 which plays upon a large sounder 10. The means for releasing the alarm just before the shutter opens, Figs. 4 and 5,con-

of which have inwardly projecting points 17 .a

and 17 bearing on the cam wheel, the lever 14 serves to release or stop the alarm hammer 9. The trigger 18 releases a compressing arm 22 for compressing a bulb, and transmitting pneumatic power to the shutter of a camera, as shown in Fig. 1. The power transmit-ting mechanism remains idle momentaril while the cam wheel is advancing until t e projection 17 on the tail of the pawl-trigger 18 1s' forced into the cam notch 16 by sprin 19, and releases the pawl 29 of trigger 18 om any one of a series of notches 20 on wheel 21 fixed on transverse shaft 21a carrying the compressing arm 22. This arm 22 projects out of the casing and is impelled by a s iral spring 23 encircling .the shaft 21a on W 'ch out doing so the whole i' wound by a handle 41.

the compressing arm is mounted. A. compressing cup 23 is hin ed to the edge of a ollow all-shaped bulb older 24 located outside above the top of the case 1. This compressing cu or thimble rests by gravity upon the free en of the compressing arm in osition to be pushed into the open side o the bulb holder.

25 is an ordinary rubber bulb, bellows or air holder from which a tube 26 leads to the camera shutter in the old-and well known way, as seen in Fig. 1. This bulb is held in place by means of an open slot 27 and hook 28. When the trigger 18 is tripped by the cam wheel 11, the pawl carried onL the trigger is pulled back with it by a luv-30 through the force of spring 19, thereby releasing the compressing arm, forcing the cu 23 into the bulb and transmitting power to t e shutter.

The time-exposure mechanism is located on the right ofthe alarm mechanism, as seen in Fig. 3, and it consists of a large gear 35 carrylng a pawl and ratchet 35a, and connected with a train of gears 36, 37, 38, and 39, terminating in a fan-wheel governor 40, andbeing actuated by a main-spring 35? v After the shutter has first been 'opened by the power mechanism, itis allowed to close when the power is withdrawn from it, in the manner now to be described. The bulb-holder 24 is secured to the free end of a rock-arm 50 on a rock-shaft 51 encircled by a coil spring 52, and the arin is rigidly held to the action of the compress-A ing arm 22 by a ratchet 53 on shaft 51, in con-4 junction with a spring-actuated pawl 54 on a pawl-trigger 55, the pawl being released. by a spring 57 and a lug 56 on the short end of the trig er. This spring 57 holds the long arm of t e trigger to the action of a tripping cam 58, the latter beingactuated by a main spring 35b and train of gears 5,9, 60, 61, and

62", (Fig. 4). The cam 58 is fixed to turn hard with its center within the gear 61, like the other tripping cam 11 for the pur ose of adjusting it with the ointer 43b of 'al 43, the pointer being fixe to the cam, wqhereby it may be setto operate earlier or later. During the reliminary running of the timing mechanism, that is to say, before the alarm is set oli, and before the compressing arm is tri ped, the shutter-closing mechanism, whic is held out of action'through the medium of an arm 62 loosely pinned to the long arm of triI ger 18, has u on its righthand end a wege 63a which- 'es beneath a thin exible clutch-thrower 64, the free end of which passes astride the hub of trip ing cam 58, and throws the clutch teeth 65 ig. 9) on the underside of cam 58 in engagement with similar teeth upon the upper part. of gear 61. When the. trigger 18 is tripped, the wedge is pushed out from under said clutch-thrower 64. This movement locks closes,

through the action of an extension 68 on the tail of the trigger 55 which extension lifts one end of a rock-arm 69 causing its opposite end to press down upon a similar extension 70 on the alarm controlling lever 14. This lever 14 stops the alarm by moving its upper inturned end inward in the way of teeth 9a on a crown-wheel 9. The inturned end of the lever 14 projects through a slot 9b in the plate la, as seen more clearly in Fig. 8.

The whole machinery is thrown in and out of action by a stop 71 shown in Figs. 6 and 10, vwhich stop is rojected in and out of the 'way of the fan w eel 40 by a hinged arm 72 extending `out of an arc-shaped slot 74. When this arm 72 is swung to the left it presses the stop 71 back out of the path of the fan-wheel and allows the machinery to work. A reverse movement will Stop the machinery.

Thus constructed the operation of m device may be brieily summed up as fo ows: The alarm and time exposure mechanisms should iirst be wound by the handles 40 and 41. The pointer or dial42 should now be moved around to any one of the figures from 1 to 5 which indicate the number of minutes which will ela se before vthe shutter will Work. This give the photo rapher time to leave the instrument and ta e a picture of himself in any desired position, such as running, jumping, swimmin etc. If a time exposure 1s desired, it can e had by setting the pointer 43h of dial 43 at any one of the divislons from 0 to 60, re resenting the number of seconds that be allowed. The apparatus may now be laced upon the ground near the camera, an the compressing arm pulled back byhand until the triger holds it. The bulb holder is also brou ht orward by hand into set position. starting and stopping arm 72 should be thrown from right to left to start the machinery golng. I t will continue to go until the alarm releasing lever operates, then the alarm begins to sound and continues while the photograph is being taken. The further revo ution of the cam wheel 11 trips the compress' arm and works the shutter. .When the bu b holder drops back, the shutter taken.

scares Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. ln a portable camera attachment, an automatic time-mechanism and an automatic alarm-mechanism, in 'combination with a time-exposure mechanism, means for graduating the time eX osure mechanism, a casing within which a of said mechanisms are housed, an exterior bulb-holder, and means for compressing a' bulb within the holder.
