. Y Application tiled January 16, 1897. Serial No. 619,452. (No model.)

To all whom it may concern:

Be it known that I, ADoLPHUs PnrnRsoN, a citizen of the United States, residing at Lansdowne, in the county of Delaware and State of Pennsylvania, have invented a certain new and useful Improvement in Auto matic Polyscopes, of which the following is a specification.

My present invention relates to a new and useful improvement in automatic exhibitors for carpet, wall-paper, and the like, and is what I am pleased to term an automatic polyscope, and has for its object to provide positive and effective means whereby a series of samples may be automatically exhibited one after the other and when so exhibited will give a realistic appearance to a surface of indefinite extent, being covered with a material of a design or a pattern; and a further object is to cause the patterns or samples to dwell through a sufficient space of time to permit a careful inspection thereof, after which they are to move one step, bringing the next pattern into position, which will then dwell for a similar purpose, and so on throughout the entire series of samples.

Vith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and` operation will now be described in detail, referring to the accompanying drawvsecured or formed the worms M and M', which ings, forming a part of this specification, in which- Figure l is a longitudinal section of an apparatus built in accordance with my improvement and adapted to exhibit samples carried by a traveling belt wound upon two reels; Fig. 2, a plan View thereof.

In carrying out my invention as embodied in the drawings I provide a mirror-box A, which may be of any suitable design, such as rectangular, having the entire surface of its walls covered by suitable mirrors, and this box may be either rigid or collapsible, as best suits the requirements or fancy of the user. This box is mounted upon a base B, from which the belt C, carrying samples, is arranged to travel, as will be hereinafter set forth.

Two reels D and E are suitably journaled veither in a portion of the framework of the d belt, so that when these wheels revolve in one direction or the other the belt will be caused to travel in the corresponding direction and will therefore be drawn from one ofthe reels and permit the opposite reel to wind the same thereon. The sprocket-wheels are mounted upon suitable shafts, on which are secured pinions H and I-I', with which the segmental gearsI and I' are adapted to mesh when being rotated, and these segmental gears are rotated through the worm-gears .I and J', which latter are secured upon the sameshaft as the segmental gears.

A' longitudinal shaft K is so journaled in suitable hangers L, depending from the under side of 'the apparatus, as not only to revolve therein, but also to have a free longitudinal sliding movement when occasion requires and for the purpose next explained.

Upon the ends of the longitudinal shaft are are adapted to mesh, respectively, with the worm-gears .I and J', and the length of this shaft is such that but one of these worms may remain in mesh with its worm-gear at the same time, and therefore but one of the segmental gears will be revolved at one time, the segment I revolving in the direction of the arrow marked thereon, while the segment I' revolves in the opposite direction, as indicated by the arrow marked thereon Thus when the segmental gear I' is revolved the belt will be caused to travel in the direction of the arrow marked adjacent thereto, while when the opposite segment'is revolved the belt will be revolved in the opposite direction. The shaft IOO K being revolved by means of a suitable belt running upon the pulley N may be forced longitudinally, as before set forth, in one direction or the other, and when so forced one or the other of the worms M and M' will be carried into engagement with its Worm-gear, and this longitudinal movement of the shaft K is brought about by means of the cams O and O', which are secured upon said shaft and adapted to act upon the lower ends of the pins P and P', respectively, when one or the other of said pins are sutliciently depressed to lie in the plane of action of its cam. By this arrangement it will be seen that when the belt is traveling in the direction of the arrow, as shown in Fig. l, the worm M' being in mesh with and revolving the worm-gear J', it will be only necessary to drop the pin P into the eld of action of the cam O, when the latter, during its revolution, will come in contact therewith and riding thereon force the shaft K longitudinally in the direction of the arrow l, thus drawing the worm M' out of engagement with the worm-gear J', while carrying the worm M into engagement with the wormgear J, and as one of these two worms is righthanded, while the other is left-handed, it follows that the worm-gear J will be revolved in the opposite direction from that of the wormgear J', thereby carrying the segment I in the direction indicated by the arrow marked thereon, which will reverse the travel of the belt, causing the 'same to be unwound from the reel E and wound upon the reel D. Now to bring about this reverse movement of the belt by the dropping of one or the other of the pins P and P', I provide the levers Q and Q', which are suitably pivoted at R and have i j ournaled therein the rolls S and S', which are adapted to bear upon the upper surface of the belt and the samples and carpet carried thereon, so that so long as the samples are passing beneath either of these rolls the levers will be held in an elevated position ,while when the samples pass through fromA above a difference in the thicknesses will cause the rolls to drop, and with them their levers, thereafter said rolls bearing upon the belt. The inner ends of these levers are connected together by cross-bars T, having pivoted thereto the pins P and P', as clearly shown in Fig. l, said pins being guided in suitable housings, so as to withstand the force ot' the cam action thereon. It will therefore be obvious that so long as the samples continue to pass beneath either of the rolls S or S' the pins will remain in an elevated position out of the field of action of the cams; but immediately upon the passage of the last sample wound in that direction the roll, dropping therefrom to the level of the belt, will depress its pin, which will immediat-ely be acted upon by the cams, bringing about a longitudinal movement of the shaft K, as before described, thereby reversing the travel of the belt. The object of this is to cause all of the samples iirst to pass beneath the mirror-box for exhibition, and when reaching their limit to bring about the reverse movement of the belt, so as to rexhibit the samples thus continuously so long as power is applied to the pulley N, thereby obviating the necessity of an attendant to care for the machine.

It is very desirable for certain classes of exhibitions that each sample shall dwell a certain length of time after being brought beneath the mirror-box in order that a person may observe the effect thereof while at rest, and then after this given time for this sample to quickly pass from the mirror-box and another take its place, and so on throughont the entire series of samples, and this is accomplished by one or the other of the segmental gears I and I' first passing into mesh with the pinions II or II' and bringing about the revolving-of one of the sprocket-wheels, which will cause the belt to travel in the desired direction,and thereafter passing out of mesh with said pinion, which will permit the sprocket-wheel to dwell, during which time the belt will likewise remain at rest, and this is so timed relative to the width of the samples that iirst one sample will be carried within the mirror-box in proper position and after dwelling the desired length of time will be drawn from said box and another take its place.

Then the belt is being drawn in one direction, the reel upon which it is being wound must of necessity be revolved, but by such means that it may travel at varying speeds on account of the increase in the diameter ot' the reel or belt as it winds thereon, and this speed of necessity must be controlled by the belt itself,as will be readily understood. I accomplish this result by placing a suitable pulley U upon each of the sprocket-wheel shafts and leading a belt therefrom over a suitable pulley V upon each of the reels and so arranging these belts as to provide for a certain amount of slippage upon their pulleys, it being noted that the belts are to drive the reels at a rate of speed which will take up the sample-belt as fast as it is fed by the sprocketwheels when the reel is of smallest diameter by reason of just beginning to wind the sample-belt thereon. From this it may be seen that as either of the reels continues to increase in diameter bythe accumulation of the sample-belt Vthereon this tendency to draw said belt faster will be resisted by the hold that the sprocket-wheels have upon said belt, and this hold being sufficient to overcome the pull of the belts upon the pulleys U and V will permit the last-named belts to slip in proportion as they have a tendency to overfeed the reel, or, if found more desirable, a spring or Weight may be attached to the reels for the winding on of the sample-belt.

From this description it will be obvious that so long as power is applied to the shaft K the apparatus will continue to operate to successively bring in place sample after sample for the inspection of the prospective customer,

and when the customer looks into the mirrorboX a realistic eect is had of an unlimited surface being covered by the sample then at rest in said box.

5 An apparatus of this description will answer nearly al1 the purposes of a salesman, since samples of the entire stock of an establishment maybe exhibited one after the other withv all the effect of having an indefinite 1o length of the material spread upon a floor or wall, as t-he case may be, for the inspection of the prospective customer.
