the Scheuls refenedto in these Letters Patent and making' peut otthename.

I, THOMAS Filo-ATE, of Cincinnati, Hamilton county, Ohio, have invented new and 'useful Improvements -in Box-Stereoscopes, of which the following is a specification. A

Nature and Object of the Iiweatm.l

.This invention relates to the class of box'fi-nstruments which contains a series of stereoscopic'views that are capable of being elevated one byrone, so as to be brought within the t'ocu's of a pair of lenses, or of two pairs, situatedat opposite 'ends' of said instrument; and v v The first part ot' my improvements relates to' a'peculiar arrangement of devices, whereby a single view vorI slide is lifted from a. suitable Vcarriage or' conveyer,

and, after being inspected for any desired 'length of time, -isrcturned to the conveyor, and another one taken up;y it' being nnderstoodthat said -conveyeris caused to advance a proper distance after one 'view is deposited in it,aud before'the succeeding one is ele'- i'ated therefrom.

. My invention also relates to an `improved'device for holding the carriage.

I General I {cscriptfiou with Reference to the-lmv'iny.

Figure 4 is a'perspective view of the conveyor that contains the views;

Figure 5 is lan enlarged section, taken through one end of a view-frame; f

Figure 6, is a side elevation oi'a portion of the conveyor, with a number of view-frames in position;

Figure 7 is a'perspeotive representation of a viewfia'ine; and

Figure 8 is a rear elevati Figure `9 is a perspective view, showing a modifica'-l tion of the carriage, and also of the devices for ele.- vating the views.

In the modilication shown in fig. 9, the carriage H is represented as mounted upon wheels 2, whichrun upon the tracks I I', and said tracks may be united to bars 3 and 4, one of which is furnished with apertures 5, so as to'permit of the tracks being attached to lthe ends of box A.

.Slots 6, in the other bar, 4, enable the proper adjustment of tracks I I', so as to bring them to a. horizontal position, thereby facilitating the movement of carriage H.

In order t o prevent any accidental displacement of B', whose under sides are provide of' the devices for sbift'- l ing the lenses. y

tb-e can-iage H, vit is provided wit-h spring-clips 7,

which embrace `the rails I Iin the manner shown.

In" this illustration vthe cranks F', instead `of sup" porting the lower member o f the gate S', is shown as having a ptman, 8, attached to it, whose upper end is secured toa reciprocatingiblock,l9, from which projects thc lifter R.

The reciprocating block 9 is confined to' a vertical path by a guide-bar, 10; but, if preferred, said block may siide'witbina suitable under-cut groove in vthe sides of box A. A represent-s the box of the instrument, which .is open at top, and has hinged toit, it a c', tbe-lidsB d with mirrors, or

otherwise arranged vto reflect light upon the'views.

These lids,`wheu opened, are maintained at the desired angle by means of, tongues C C', that are secured tothe ends of the box A, and 'which bear against the hinged edges of the lids with sufficient force .fo

prevent them falling.

f J ou'rualed within the. sides of y the box is a rotating shaft, D, which is provided with au externaiwinch or with ara-ck, G, that is secured tothe under sideof a carriage, H.

The carriage H slides upon twotguide-bais or tracks,l

I I','.tbat extend from end to end of the-box, and at a proper height above the bottom of the same', and ac-` cidental displacement-of said carriageis prevented by the spring or springs J ,f that bear against the sides of said tracks. g Secured to the carriage H,by screws h, is the viewreceptacle or conveyer K,-wh0s'e sides are provided with al seriesof vertical project-ions, k, which correspond iu number witlrthe teeth of theraek-bar' G, andv said projections are for the reception/and rctention, l in their proper positions,l of the view-frames'njhici are constructed in the following manner:

The upper member of each frame is composed of a piece of sheet metal, L, whose sides are recurved,.as

shown atl l', thereby forming a trough between them.v

Projecting downwardly from the top member L, and at a proper distance from the .ends thereof, are

two other recur-ved piecesof sheet metal, N N', whose lower extremities are united by a wire. O. having at its mid-length two clips, o o.

A portionof each ofthe end pieces N N' cut away, as shown at n a', so as to permity of the views being slipped within said end pieces, and shoved up into the recess M, after .which they arel allowed to drop as fast as necessary, and to'be retained by the clips o o'.

v ject beyond the pieces N N' Projecting from the bottom of the end pieces N N are points l?, which prevent the frames becoming entirely dislodged from their conveyor K, whenever the views am elevated for the purpose of inspection.

, The end pieces N N" it snugly within the sides of the conveyer K, and their recess d portieri M restsv upon the projection k, asshown in lig. 6.

The two ends of the upper members L, that proand the sides of the con- 4veyer K la, are intended for the reception of studs or spurs It R', that are'. attached to two verticali rocating slides or gates, S S'.

These reciprocating gates are located at opposite sidesofthe box A, and are conlned within guides T T', which are secured to said sides by screws s.-

lhese gates are simply dropped in lo :thc grooves 't of said guides, andallowed to rest upon the cranks F these gates ascend and descend.

plied to drawers V V', thatV are capable of being slid out or in, so as to obtain the proper focus for pictures.

slots v and screws or studs v'.

` The tnbes U U project through and l'play `freely within slots not' the drawer, and the inner ends of said tubes are attached to two shiflableblocks, W' W', which arrangement permits of the lenses' being ad- `v usted toward or from achotheiyso as to be exactly suited to the eyes of different spectators.

rlhe middle of the rotating shaft D may be jonrnaled within a support, X', that projects from-the hot.

',lhe slot Y, in one side of thc box, through which the crank-shaft is inserted, is concealed by a plate, y.

Theentrance of'lght is prevented, when the drawers V are opened, by plates Z, which extend completely acrossl the topsl of said drawers, as shown in tig. 1.

Operation. Y

The operation of my instrument will he understood by referring to iig. 1, fromjwhichit will be seen that V,the rotation of the shaft I) clevates the gates S S', through the rriedinm of cranks I F', and, in so doing,

, the spurs R R engage under the ends of the frames L,\vhich project beyond the conveyor K, and thereby lift said frame, with its accompanying views, out of the conveyer.

When. the cranks have reached the vertical position 'shown in iig, 2, the frame has been completely elevated, and the picture brought directly in line with lenses, which elevated position of the picture can be maintained as long as the spectator desires.

, By completingtbe revolution' ofthe crank, so as to 'y-recipso that,- at everyentire revolution of said cranks,

^ guided in a propel' path bring itto its lowermost position, the frame is vdepos- 'ously been elevated. V While the cranks F F' are passing their lower dead-points, the tooth l is engaging with, the rack G, in suoli a manner .that,.by time said. cranks are about to elevate the gates, the carriage H has been moved a .suiiicient distance to causo the spins It R' to engage with a frame next to the one' which had just been deposited in the conveyer, that is, lifted out and returned to the receptacle, in the' manner previously described.

y'.Lhis operation is repeated until every view in the linstrument has been inspected, and the carriageH moved'along its ways until it strikesV the end of the box A, after which the rotation ofthe crank-shaft must be 4reversed, sofastoexhibitthe pictures, by ruiming the carriage in an opposite direction. f

' For thepurpose of more readily distinguishing the "parts, the elevated frame in fig. 2 is represented, as being lifted entir'ely ont ofthe conveyer K; but 4in A .actuaipractice this lwould not be'thc case, the inten- `These drawers are-confined to a proper path by the tion being that the points P at 4the bottom 'of said -frames shall always remain within the conveyor` The reciprocating gate S is shown as composed of an op may be a simple. block or slide, or the cranksof the 4,rotating shaft may have pitmen to them, whose -upper curls could carry the liite'rsR, the ptmen being by verticalgrooves in the sides ofthe box. 4

. I am aware that a stereoscope has been construct? ed in which a circular holder .is made to revoli'e by the actionof a tooth and rack, the pictures being 'liftf ed from the holder by cranks, in a manner somewhat similar. to mne,.as in the patent of S. Perry, 'Zth'ot hand.
