PORTABLE PHOTOGRAPHIC GALLERY.

To all whom, it may concern.-

Beit known that I, SAMUEL WEAvEn, of Gettysburg, in the county of Adams, in the State of Pennsylvania, have invented a new and useful Improvement in Portable Daguerrean Galleries or Houses; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

Figure l is a transverse vertical section of the gallery, as indicated by the red line 3 4 in the top view ot' Fig. 4, showing the sides extended out, giving a view of the horizontal elongated sliding bars at the top and bottom ofthe movable sides, to which the ends are attached, sliding in friction roller boxes secured to the upper and lower portions of the framework ofthe gallery, showing the positions of the movable part of the root' hinged immediateiy underneath the eaves of the stationary root on each side, showing the detached or movable iiooring and ends and legs for supporting the gallery, having` horizontal arms joined to the top ends of each, secured to the sides of the bottom beams of the frame-work when in use, the arms supporting the extension part, the extension ot' which is facilitated by the sides having friction-rollers at or near the bottoms on the outside, thereby relieving the straining and exertion which they would otherwise be subjected to in the pulling out of the movable sides. Fig. 2 is a longitudinal vertical section through the gallery, as indicated by the red line l 2 in top view of Fig. 4, showing the ends of the horizontal elon gated bars, as they appear through and between the friction-rollers in the boxes at the top and bottom. Fig. 3 is a side view of the gallery, showing the friction-rollers immediately above and on the horizontal arms, (to which the legs are attached,) secured to the movable sides, and handles or rings for pulling them out. Fig. 5 is a detailed view showing the mode otA fastening the horizontal arms to the bottom joist or beam, and the manner of connecting the legs with the arms. Fig. 6 is a detailed View showing the position of the' frictionrollers at the bottoni of the movable sides on the horizontal arms. Fig. 7 is a detailed view showing the end of the horizontal elongated bar as it appears through and between the friction-rollers in the box, and a bar wit-h its end turned, forming a shoulder to prevent it from slipping through when drawn out.

My improvement has reference to a mode of enlarging portable daguerrean galleries or houses, when desired, in as convenient and simple manner as possible, with comparative ease and'very little exertion and expense. For instance, if the operator should find himself crowded from want of space in the gallery, and wishes to obtain more room for his operations, he is unable to do so unless he has providedfor this contingency, and then considerable aid and manual labor is required in the enlargement or extension ofthe gallery, in adjusting the sides, ends, ooring, and framework to their proper places, which is very inconvenient in the present mode of doing it, and sometimes difficult when the parts become warped from wear and tear in the usage. It' provision has not been made, the operator may tind himself in a locality where probably material is not convenient and accessible to. lf otherwise, considerable delay and expense must be incurred before the same can be got ready. My improvement, which is intended to obviate this difticulty and inconvenience, is as follows: ln the construction ofthe gallery I make thel movable sides whole. or in one piece, as it were, having three horizontal elongated bars attached to the bottom of each side and near the ends, sliding through and between friction-rollers in boxes secured to a joist underneath the flooring. At the top and about the center ot' the movable sides are two elongated bars attached to each side, passing underneath the ceiling joists in friction-roller boxes. Then the gallery is to be extended, by catching hold of the rings or handles on the outside of the movable sides and pulling they are brought out to the extent ofthe length ot' the bars, being prevented from slipping through the boxes by a shoulder, (l, on the end ot' each, consequently the hinged roofs under the eaves of the gallery, which were vertical, hanging in a lapping position over the movable sides, are raised up to a position parallel with the slope of the stationary roof. The movable ends and iiooring are then placed in their proper places, and the whole is then as complete and substantial as it' the gallery had Anot been enlarged, which is an advantage over those not having this arrangement, as the whole is constructed and provided beforehand.

To enable others skilled in the art to make and use my invention, I will proceed to de-A scribe its construction and operation.

I construct my gallery A ot' an ordinary house-like form, the framing, sides, ends, Hooring, and rooting to be of light material as possible, having a suitable number of windows and doors, with skylightopenings on the roof. The movable sides g are framed and made whole or in piece, as it were, independent of the gallery. The movable ends i and looringj are made inthe same manner. The sides g, when drawn in or closed up, may be held securely to the ends of the gallery by a hasp or hook, or any suitable mechanical means most convenient, the same as when drawn out and movable end pieces, z', and looringj are put in their proper places. The dimensions of the gallery are not limited to any particular size, but to be optional with the director in the construction of them, the extent to which the sides are drawn out the same. The movable end pieces i' have two small pins, It kf lc 7c', on the edges Z Z, which lit in holes m, made to receive them on the edge l ot' the ends of the galery, so as to keep them in place when joined on for enlargement. h are the movable rool's, hinged immediately'under the eaves of the gallery, and, when the sides g are closed up, hang down in a vertical position against the sides, and when extended out they are r iised up to a position parallel with the slope ot the stationary roof. C are the elongated `sliding bars, two of which are connected in a substantial manner to each movable side g at the bottom near the ends, passing underneath the looring between thejoists, through and between friction-rollers in boxes D, fastened on the side ot' the joist about one-third ofthe width from the edge ofthe gallery. Each end fthe bars C has a shoulder, which prevents them from slipping through the boxes, as seen more clearly in Figs. 2 and 6, when the sides g are extended out. At the top and about the center of the sides g, only one sliding bar is necessary, which extends immediately underneath the eeiling-joists through friction-boxes, the same as below.

B are the legs which support the gallery, having horizontal arms B projecting out a little beyond the extent to which the sides are drawn out, with metal plates on each side, forming a shoulder at the ends and fastened to the side ofthe bottom joist of the framing by means of screw-bolts, as seen in Fig. 5. The arms B are mortised out 'on the sides near the ends to receive the legs B, which are doubleitenoned on the top to t them, so as-to be slipped on and oii' as occasion may require, the legs being planted firmly in the ground. It' there is danger of the gallery swagging down or it is not steady enough by reason ofits weight straining the arms too much, the arms may be of one piece, extending from leg to leg, and bolted underneath to the bottom joist of the framing. The arms are placed immediately under and opposite the friction-rollers E, attached to the movable sides g, forming a bearing and support, and enabling the sides to be drawn out without straining or much labor. fare the handles or rings secured to the sides for the purpose of pulling them out when desired.

Like letters indicate correspondin g parts in all figures of the drawings.

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

The enlargement of a portable daguerrean' gallery or house by means of the elongated sliding bars C, friction-roller boxes D, movable sides g, and friction-rollers E, as arranged and operating substantially in the manner herein specified.
