ordinary camera B, or the camera in which the negative is placed. rl`his opening 12 intheforward end of the bellows A is reinforced by a gasket 14, the edge of which is unattached so as to facilitate the application of the heb lows A to the aforesaid lens 13. Adjacent.

the forward end of the bellows at the upper and lower side edges thereof, `rings 15 attached in any approved manner and these rings are adapted to be used in connection witha support for the forward end of the bellows, andI are. also serviceable in reducing 'the length of the bellows when necessary.

The rear er enlarged end of the bellows A is secured in any suitable or approved maiiner within a. box fra? ie. C of suitable size, the said box frame being preferably rectangular in general contour, as is illustrated. 'The bellows is 4attached to the forward portion of the box frame, but the rear portion of the said box frame is open, and an opening 16 is made in one side or end of the box frame (l, as is particularly shown in Fig. 1, and furtheri'uore in the construction of the said box frame an inwardly extending flange 17 is produced at the upper rear edge of the frame, and a similar flange 17LL is produced at the lower edge., the two anges 17 and 17'a incet-` ing amating iiange 17" that is at the closed end portion of the said box franic, as is alsoV shown in Fig. 1. '.lhe box fraiiie C is provided also with an interior rib 1G@L correspending tothe flanges 17 and 17a and 17h,

but the iib 16a is located at about the central portion of the box frame, asis illustrated iiil Fig. 2, and is carried from a point liush with the wall of the opening 16 along` thel top of the box frame, thence along the closed end and again along` the bottom,A terminating also flush with the said rear 'all of the opening 1G, forming thereby within the said box frame arear chamber C" that is adapted to receive a holder D for the sensitized papel' upon which the reproduction is to be pro.

duced. his holder D is removable from the box fraiiie and is provided at its forward portion with a slide 1S of the usual type, that travels in ways 19 iiitcrim'ly produced in the said holder, as is shown in Fig. 2, and at the rear portion of the said iiolder is a pane of ground glass that has bearing against the flangesk 17, 17, and 1,7". An opaque board `21 is adapted to normally lie against the forward face ol' the ground glass :20, andtliis opaque board in its turn is adapted as asupport for the sensitized papor-22` employed,

` clips 23 ot' any desired fin-mation within a recess 31 produced in the Q, metio camera support F this support is construct-.

the board 21 and paper 22 being held proper position within the holder by sp 'in enlarging base beingr best illustra-ted in Arbase E is provided for the camera, said Fig. 3. This base is in two tions, a .tor-- ward section e and a r ir section e. Th,

rearsection e is provided the rear end poi-tion'ofV its under face with a buckle 2li, and the section e is proif'ided at the l'orward end portion of its under ia e with a. strap 23 to be' received by the buckie. the use ol which will be hereinafter described. The rear section e of the ill is adapted as a support for the rear portieri of the iinlarjing camera. This rear section e ot die l' provided-upon its upper face adjacent each of its sides i yith a longitudinal lguide liar 24, said guide bars beingr in paralieiisin, a nd the guide bars stop short ot the ends ol the base. The inner faces ot' the guidel liars 24 are downwardly and inwardly inclined, as is shown at 25 in Fic. o, so as to provide slideways for the 'sliding i'rainc- E". l`liis sliding frame consists ol' parallel side ineinbers 26and end members 27, the side ineinbers Vbeing.beveled oorrespondinglf to the bevel surfaces 25 or" the guide bars 4, as also shown in Fig. o.

The box frame of the enlarging camera is removably secured to the rear end portion ofthe sliding frame E by means ol' setserews 28, or their equivalents. that are passedthrough the bottoni portion oi thex box l'rainiy at the front, and into the side incinlicrs 2G of the sliding traine, as is illustrated in Figs; 2 and 3. Thus the enlarging camera has ample adjustment upon its base and the sliding frame E is held in adjusted position by means of any improved type of latch. in the'drawings the iatch 3l is in the l'orni of a cani adapted for engagement with an outer side edge of the inner side incinbers 'olI the said frame, thc said latch. being' located upper face of one ,of the Tuide bars 24. :it the forward end of the` aso section if', a transverse recess 28 is produced in the under faces of tho cuide bars 24, as best shoun in Fig. 1f? flhis base section c also carries a s ring.)r clip .,EU- that secured about centraiiy to its upper faire adjacent ils forward edfe, as is illustrated in Fig. 53.

l-,telativcly to the l'ornard base section w;

1t is provided with longitudinal guide lia rs 552 that correspond to the guide bars 2li oll the section c', being of like construction, andl these guide bars $32 iornrslide-ways for anl other slidingr l'raine liz, which consists olV side bars and ond liars H4, and this siiflingl frame E5 is held in adjusted position means ol'gga cani hitch 30 mounted in the recessed poi-lion Sil ol' one i ol the guido bars .32. 'lflic sliding haine lCi' is adapted to carry a coinbin 'l nd l for example,

by i

ed bctows a Yol' said nienibcrs, as is ed as follows: Standards 35 are pivoted attheir lower ends to the inner faces of the side members 33 of the frame E2 at their rear ends, and the said standards are connected at their bottoni portion by a cross bar 36, and at their free aids or upper portions, by a corresponding bar 37, as is best shown in Fig. 2. When the standards and their connecting members are in use they have an upright po- 7 siiion, as is illustrated in Fig. 2, and may be crniod a'supportiingr traine since the parts named constitute a traino adapted as a support for the bellows A of the enlarging camera, but when the said supporting niechanisin i" is not in usc, thc supporting' l'raine just referred to is 'folded down into the space between the side inoinbers of the sliding traine E2.

Two pairs oi" links are employed .as braces ior the standards these links are located it cach side of the slidiiri; l'ranie and are designated, one as 258 and the other as 39. The links Sie are pivoted at one of their ends to the inner face ol lhesido members 38 of the idinrV l'raine E! adjacent the forward ends Iillustrated in Figs. l and 2, the links 39 are pivotally connected with the other ends ofthe links 38, and the links 39 terminate at their free ends in hooks 40, and these hooks are adapted to receive any one of adjacent rings 35, thus to support the 'forward end of the bellows A, and by havin (hr the rings 15 in series any one of the soi'ics ol' rings may be engaged by the hooks 40, and in this nianner the bellows may be drawn out and supported its full length, or inay, be shortened up as occasion ina require. Each link 39 adjacent its termina 40, is provided with a slot 41 of abayonet type, and this slot 4l whcnthe said supporting; incch anisin F is inset up position receivespins 42 that extend l'roin the outer side laces ol' the standards 35 at their upper ends.

'lhc standards 3.3 also serve to support a lablc '13, best vshown iii Fi f. 3, and the Isinaller cainera .B is adapteri to rest upon said table. This table is adjust-able for dillercnt sized canlieras, and is usually inadc ol iliin shcct inetal and provided with downwardly catcndinpr side llaiiges 44, and the said flanges are carried beyond the 'rear end ol` thc lrcd ol' thc table to lorin oars 45, and thesicars are provided with slots 46, through which slots set screws 47 pass into the said standards 35. 'lhe table 43 extends rearward bei wccn the lbrace links 3S and 39, as is shown particularly in Figi l, and the flanges tl ai the forward :1nd portion of the said table 4:; are lient horizontally outward to l'orin stops 18, which sto )s when the table is attached lo lliciaiidards 35 and is in horizontal position eng-age with the forward edges olV the links 3.8, as is shown in Fig. l, and in lliis nianncrlhc forward rnd ol' tifo The gui e bars 32 on the base section e are vprovided at their rear end's with transverse recesses 281km thelr under faces, corresponding toy the recesses 28" l'in' the guide bars for tlie base section e. The table 43 is rovided with a slot 49 through which a suita le screw may be assed to secure the'srnaller camera B to sai table.- `About centrally at the rear end.` of the forward base section e a spring lclip 5() is secured, corresponding to the clip 29 on the rear base'sectione, and when the device is set up the two base sections e and e 'are eoupledtogether b a'coupling bar 51,

" that is laced-beneath the spring clips 29and 50, an the saidl coupling bar 51 vis provided at each of its ends with an ucpwardly extending'lan 52, but I desire it to be understood that Idar; not confine myself'to any particu- I.lar means for uniting the base sections, or any particular means for holding the sliding frames E Vand E2 in adjustment.

After the device has been set-up and attached to the camera as has been stated, the operation is, practically as follows: The ground glass is removed from the small camera .B and the negative introduced in its place, the opaque board 21 is new removed from the ground glass in the holder D of the enlarging camera and the bellows A vthereof is adjusted until the subject of the negative appears in required 'size on-the' said ground glass 20, whereupon the bellows of the lsmaller camera B i's adjusted until the said subject is in perfect focus on the said round glass. The holder D is now removed from the box frame and the opaque b'oard 21 is againintrodueed in said holder accompanied by the sensitized paper; adapted to re,- ceive the re resentatiortof the object. Vlhenv the holder` i3 has, been pro erly loaded it is ,replaced in the box frame and the slide 18 is removed'from the holder D, the light passing through thenegative and through the,

lens reprpducing the subject in the desired increased size upon the sensitized paper in the said holder.

When the device-is to be knocked down it is removed from engagement with the camera B. The box frame (.3 is detached from the base section e' by removing the se't screws 28, then the table/ 43 is disconnected from the standards35, the bellows Al is unhookcd from the links'39, and the said linksnf) are disengaged from the pins 42 on said standards. 'lhe links 89 are now folded inward upon or -cngagedby the links 38, andl the links in their folded position are carried/ down into the space surrounded by the members of the'sliding frame E2, thenthe standards .S5/and acsaid. space etween the folded links. I Thus Patent,-

eompanyin parts are folded down also in the a Hat section of the device is obtained. The

bellows is then vfolded within the box frame and the table43 is' laid upon the foldedi'bellows, then the section e is made to-cover that face of the box frame, for example,y from which the bellows extends and the recesses 28V in the guide -bars 32 of said section are made to receive flanges 17C formed' at the front marginal portion of thetsaid box frame,

as is shown in Fig. 4. This base section e thus constitutes a cover for the'front of the box frame C, and the seetion e is then made to serve as a cover for the rear s'ide of the said box frame, the recesses 28a of its guide barsreceiving the flange 17b at the rear portion of the box frame, as isalso shown in Fig. 4.` The two sections e and e adapted as the sides vfor the package formed as stated, are pressed to place and will rest smoothly-upon the back and front surfaces of the box frame,` as is shown in Fig. 5, and then the strap 23 is earriedto anI engagement with the buckle 23 Y holding the parts in their assembled position,

and since the box frame is provided with a suitable handle d, at its top portion, the pack-` age formed as'described can be, readily earried from place to place.

Having thus described my invention, I claim as new and desire to secure by Letters 1,'In an enlarging camera, the combination with the support, ofa bellows having' one end fitted for adjustme lt to a lens, a frame at the rear of the bellows, a holder in the frame provided with, a ground glass panel, and a removable cover, a folding'frame at' the front of the bellows, said frame comprising a basefhaving standardspivoted thereto at one end, a table for supporting thel camera.y adjustable on the standards, and folding braces connecting the free ends of the stand-' ards and the base, the ends of the braces connected with the standards bei-ng extended to form hooks foixsupporting the bars. v

2. [n an enlarging camera, tlie'combina'- tion of an extensible base, a camera supported by the base, standards pivoted to the base, folding braces connected with the standards, the free vends of the baseb'eing extended beyond the standards to form hooks for supporting the camera bellows, and a table connected with the standards for supporting a smaller camera.
