GOLLAPSIBLE CAMERA.

Application filed February This invention relates to cameras in genzral but is more specifically designed to produce a collapsible form of camera which, when extended for use, will have a considerable focal length, but, when collapsed, will form a neat, compact package cable of being carriedin an ordinary pocket of the users clothing. To this end the preferred embodiment of the invention hereinafter described more in detail comprises a rectangular main casing of relatively small depth, a section telescoping sidewise into said casing and carrying lenses mounted on a sliding carriage and a collapsed bellows extension, or hood for the same, and a front panel or flap hinged to said telescoping section and adapted, when swung outward and downward, to serve as a support for the carriage and lenses when the latter are pulled out into operative position and said hood extended.

The best form of apparatus at presentknown to me embodying my invention is illustrated in the accompanying drawings in which,

Fig. 1 is a side elevation, with parts broken away or in section, showing the camera in position fortaking a photograph.

Fig. .2 is a detail axial section showinfi the bellows extension collapsed.

Fig. 3 is a front elevation of the. bellows extension and lens in operative position.

li ig. 4 is .a longitudinal section on line 44 of Fig. 3, with parts br ken away.

Fig. 5 is a similar section on line 5- fi of Fig.

Fig. 6 is a plan view with parts broken away and others shown in section on line 6-6 of Fig. 1. I

Fig. 7 is a detail horizontal section on line 7-7 of Fig. 4,

Fig. 8 is a detailsection on line 8--8 Fig. 2, and Fig. 9 is a section on line 9 9 of Fig. 8, showingthe parts in positions assumed while carriage 1.6 is beingdrawn outward.

Throughout the drawings like reference characters indicate like parts. 1 is the main casing enclosing the plate or him holder, shutter and related parts of any proper construction (not shown) and having a front opening 1 in which is mounted the telescoping section 2. This telescoping section has a "narrow rear flange 3 with a narrow groove 4 located immediately in front of 1, 1926. Serial No. 85,127.

said flange, and also a front flange 5 with a similar groove 6 just back of it. 7, 7, are vertically movable plate springs each rigidly mounted at one end in the main casing 1 on a cutaway block 7 and carrying at its other, free end a block 7 having a beveled upper face adapted to bear against the lower edge of flange 3 when the telescoping sect-ion 2 is pulled out, as shown in Fig. 1, and against the under surface of said section 2 when the latter is pushed in, as indicated in dotted lines in Fig. 1. As a result of this construction, when the telescoping section is pulled out the upper portion of the front plate 1 of the main frame engages groove 4, the telescoping section 2 being forced up against it by springs 7, 7; and when said section 2 is forced inward, the front groove 6 similarly is engaged by plate 1". Conse quently the telescoping section 2 is thereby elasticallylocked in either its inner or outer position.

8 isa flap or panel hinged at 8 along one edge to section 2 and adapted to fill the front opening of Said section when said plate is swung up into vertical position, being held in this vertical position by the spring latch 9, then engaging its upper edge. hen this plate or apron 8 is swung down into horizontal position, as shown in Figs. 1, 4 and 5, it. is locked in said position by laterally extending latching pins 13, 13, carried by flexible side extensions l0, 10, on said plate and engaging sockets 14, 14 (see Fig. 7), formed in the inner surface of the front portion of section 2. The springs 11. '11, pii'oted or otherwise fastened to the side pieces 10, 10, at 12, 12, are flexed between the inner snrface of plate 8 and the bottom of section 2, when plate 8 is thrown up into vertical position as indicated in dotted lines in Fig. 4. a result of this last described construction, when the operator presses upward the slightly projecting end of spring latch 9, the plate 8 will be released and the springs 11, 11, will throw it down into horizontal position, pins 13, 13, thereupon snapping into sockets 14, 14, and elastically locking it in said horizontal position. To return the plate 8 .to vertical position, the operator presses the elastic side pieces 10, it), slightly inward to free pins 13, 13, from sockets 14, 14, and swings plate 8 upward until it is again cau ht and held by latch 9. As clearly shown in Figs. 1 to Ind 5, the flange 5 is part of a rectangular frame 5 which is held .in telescoping section 2 by screws 5". The hinged flap or panel 8 and its associated parts are mounted on this ring 5*. By taking out screws 5 all these parts may be removed as a unit from telescoping section 2. 1

15 represents generally any standard form of adjustable objective lens carried by carriage 16 which is supported by base plate 16 (see Figure 3), which is adapted to engage grooves along the inner faces of parallel rail sections 17, 17, carried by plate 8 or the shorter GXl (%l"iSl()]l rail sections 17,

17 mounted on the bottom of section Buttons 18, 18, are connected to springpressed friction locks, one of which is shown at 18 (see Fig. 8), which. are adapted to hold carriage 16 in any position of adjust.- ment on rails 17 or 17" and particularly to engage notches l8 in rails 17, 17, Fig. 9) to lock the lens carriage 16 in its outer position of adjustment. A bellows extension or hood 19 connectslenses 1.5 with the rear of telescoping section 2. Preferably said member 19 is formed of a tapering tubular section of flexible fabric, such as felt, which has its larger end fastened to casing section 2 and can be crumpled up behind and around the lens carriage 15 as shown in Fig. 2 when the camera is closed for transportation or storage.

In operating this portion of the invention to shut up the camera the user presses buttons 18, 18, inward, between thumb and forefinger, to release the locks 18* then engaging rail sections 17, 17, and pushes the carriage 16 back into section 2 before swinging plate up to close the camera and allowing latch 9 to engage and hold it. Conversely, on opening the camera,after releasing latch 9 and permitting springs 11, 11, to swing plate 8 down, the operator releases the carriage from'rail sections 17*, 17, by pressingimvard buttons 18, 18, and pulls the carriage out into operative position shown in Fig. 5, and then, by releasing buttons 18, 18, looks the carriage and the lenses in this operative position.

The general method of operating the -amera, therefore, is as follows: Assuming the camera to be in collapsible condition for transportation, when it is to be used the operator first trips latch 9 with his thumb nail and allows springs 11', 11,- to swing plate 8 down into the position shown in Figs. 1, 8, at and F. He then pushes telescoping section 2 downward to free groove 6 from front plate 1, (thereby flexing springs7, 7,) and pulls it out into the position shown in Fig. 1 and, rasping carriage 16 by buttons 18, 18, pulls out the lenses, extending the bellows hood 19 usually to the full extent as shown in Fig. although he may leave it in an intermediate position it he so desires. He then adjusts the focus of the lenses, usually by rotating one member of the lens holder so as to bring it out into dotted line position shown in Fig. l, and proceeds to lake the photograph. To prepare the camera for transp irtation, again, he reverses the above described series of steps and reduces the camera to the compact condition generally indicated in Fig. (1, in which it can be easily placed in any ordinary pocket of the clothing.
