AUTOMATIC MYRIOSCOPE.

SPECIFICATION forming part of Letters Patent No. 676,445, dated June 18, 1901.

Application nea November 7, 1900. serial No. 35,727. (No man.)

To all whom it may concern:

Be it known that I, ADoLPHUs PETERSON, a citizen of the United States, residing at Lansdowne, county of Delaware, and State of Pennsylvania, have invented a certain new and useful Improvement in Automatic Myricscopes, 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 prefer to term an automatic myrioscope, and has for its object to improve upon the construction shown in United States Patents Nos. 606,236 and 607,073, granted to me June 2S, 1898, and July 12, 1898, respectively. With these ends in view this invention consists in the details of construction and coinbination 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 drawings, forming a part of this specification, in which@ Figure 1 is a side elevation of a machine made in accordance with my present improvement; Fig. 2, a plan view thereof; Fig. 3, an enlarged longitudinal section showing the mechanism for feeding the material to be displayed looking from the side opposite to that shown in Fig. 1; Fig. 4, a section at the line of Fig. 2; Fig. 5, a plan View7 of one end of the machine, showing the trip mechanism for stopping the feeding of the material, so as to permit the samples to dwell for observation; Fig. 6, a detail view showing the clutch and cam mechanism for bringing about the automat-ic movements of the machine and Fig. 7, an enlarged longitudinal. section similar to Fig. 2, showing a slightly-modified form of mechanism for reversing the travel of the sample-belt.

In carrying out my invention as here embodied, A represents the framework of the machine, which may be of any convenient design for supporting the various parts, and on this frame is supported the display-box B, whichk latter is rectangular, its inner walls being composed of suitable mirrors C. This display-box is so arranged that the tra'veling sample-belt D passes thereunder, and when said belt dwells, as hereinafter described, the samples will be in a position to be reflected and multiplied in the mirrors C, thus giving a realistic appearance of a surface of indefinite extent covered with a material of the sample. Two feed-rolls E and E' are jour- ,naled in the frame and are provided with the flanges F and F', respectively, said iianges havingslots or openings G cut therein, in which the rods H are set, so as to move to and fro, and'to these rods are secured the ends of the display-belt D for the purpose hereinafter set forth. Gear-wheels I and I are secured to these rolls and alternately receive motion from the actuating mechanism, as follows: The right-angle lever .I is pivoted concentric with the 'roll E and has a pinion K journaled upon one arm thereof, so as to always remain in mesh with the gearwheel I, while the opposite arm of this rightangle lever has'journaled thereon the pinion K', which always meshes with the gear-wheel l', so that to transmit motion tovone or the carry one or the otherof the pinions K or K' into engagement with the driving-gear L, which is accomplished by swinging the rightangle lever for that purpose in the manner hereinafter set forth.

The driving-gearv L is journaled loosely upon the power-shaft M, and this shaft in turn receives its motion from suitable pulleys N, secured upon its outer end and adapted vother gear-wheels it is only necessary to to receive the belt, leading from a suitable source of power.

A hollow shaft O is mounted upon the dri ving-shaft M and carries a spiral cam P, which is free to Aslide longitudinally of the powershaft within certain limits and is normally held in one direction by the spring Q, inclosed in a suitable housing and bearing upon the outer end of the pin R, which in turn bears against the key R', set in the hollow shaft and sliding in the groove R2 in the powershaft. l

The driving-gear L has the pins Z upon its inner face, which constitutes one member of a clutch. The cam P has upon its outer face holes 2', corresponding to the pins l, and these represent the other member of the clutch.

IOS

S is a lever which is located upon one side of the machine and is pivotedat the point s to the frame of the machine. The inner end of this lever carries a tooth S', and this tooth is directly over and adapted to come into cngagement with the cam-wheel P. The outer end of the lever S carries a small roller S2. This roller S2 bears downward against the hub T, which is journaled loosely upon the counter-shaft U. This hub T has upon its periphery a depression T'. A spring S2 is connected near the outer end of the lever S, and the other end of the spring being connected to some portion of the frame of the machine furnishes the means of always holding the outer end of the lever S against the hub T. The counter-shaft U is adapted to' constantly revolve and receives its motion through the sprocket-wheel U', which is secured to the outer end ofv this counter-shaft and the chain U2, which passes around a sprocket-wheel U3, this sprocket-wheel U3 being journaled upon a shaft U1.

U5 is a large gear-wheel secured to the shaft U4, and this gear-wheel U5 meshes with a small gear-wheel U6, which is secured to the power-shaft M. v Thus by reason of the difference in the relative sizes of the gears U6 and U5 the counter-shaft U will receive a correspondingly slow motion.

U7 is one member of a clutch secured to the counter-shaft U and adapted to constantly revolve therewith. The hub T has upon its outer face teeth to correspond with the teeth on the clutch U7, and thus constitutes the second member of the clutch. The hub T has formed with it the ange T2. This ange has upon its outer face the cam projection T3, while the hub is in engagement with the clutch member U7 and is revolved therewith. The cam projection T3 is adapted to come in engagement with the screw T4, which is secured in the frame of the machine, and thus will throw the hub T out of engagement with the clutch member U7. The depression T in the hub T is placed so that the roller S2 will drop within this depression at the same moment as the hub T is thrown out of engagement with the clutch member U7. When this roller drops withinthe depression T', the tooth S' upon the other end ot' the lever will be raised above the surface of the cam-wheel P, and this will allow the cam-wheel to slide longitudinally by reason 0f the pressure of the spring Q, and thus will bring it into engagement with the driving-gear L. This drivinggear L will then be caused to revolve and will iu turn revolve either the gear-wheels K or K', whichever happens to be thrown into engagement with the driving-gear L at the time, l

sired. These buttons are placed on the edge of the belt opposite to the mechanism before At the junction ot' the samdescribed. XVy is a lever which is pivoted or, as I have shown it, secured to a spring XV', this spring being in turn secured rigidly to the frame of the machine. This lever is so placed that it will bear against the sample-belt as it passes over the idle roll X, which is journaled loosely upon the shaft U, and this lever Wis directly in the path of travel of the projections V, so that when one of these projections V strikes the lever it will press it outward, as shown in dotted lines in Fig. 2. The upper end of this lever WV passes through the outer end of a horizontal lever Z, and this lever is pivoted at the point Z' to the cross-bar Z2, which extends across from and is secured to the two side frames of the machine. This lever Z is shown in its normal position in Fig. 2, and when the lever W is pressed outward by one of the projections V it will communicate the motion to the lever Z, which will then assume the posit-ion shown in Fig. 5. The other end of this lever Z bears against a pin af, which is secured in the lever ct', and this lever is pivoted at the point cto the top of the outer end of the lever S. This pivot d2 passes through the lever S and has secured to it underneath the small cam a2. Vhen the lever Z is forced into the position shown in Fig. 5 by means of the projections V, it will cause the lever d and cam d3 to assume the position shown in Fig. 5, and the point 'of this cam d3 bears against the inner face of the ange T2 upon the hub T, and thus will force the hub into j engagement with the other member of the clutch U7. Vhen this occurs, the hub T will be caused to revolve with the shaft U, and this will force the small roller S2 upward ont of the depression T' and cause it to travel around the periphery of the hub. When this end of the lever is so raised, the tooth S upon its other end will drop within one of the -threads of the cam or worm wheel P, and this worm, traveling in the direction of the arrow shown in Fig. 4, will force itself out of engagement with the pins Z upon the driving-gear L, and thus break the connection between the train of gears which drives the belt. The belt will then be stationary, so as to be viewed, until the hub T hasmade a full revolution and .the cam projection 'l`3 again comes in contact with the screw T4 and forces the said hub out of engagement with the clutch U7, when the roller will drop in the depression, as before described, and raise the tooth S', so as to allow the cam-wheel P to engage the drivinggear L. Thus the length of time that the belt of samples' is stationary and exposed to view will depend upon the relative size of the gears UG and U5 and the chain-wheels U' and U3.

b is an idle roll journaled at the opposite end of the machine to the idle roller X, and the belt is adapted to pass over the roller b, over the table c and under the mirror-box, and over the idle roller X to the roller E.,

W'hen the belt of samples is entirely wound IOO IIO

upon one of the rolls, I desire to reverse the mechanism automatically, and this I accomplish as follows: In Fig. 3 I have shownthe belt of samples wound entirely upon the roll E', and the machine in operating will continue to wind the belt upon the roll E', and thus pull the rod H to the outer end of the slots Gr in the iiange F of the roll E. This rod H ext-ends through the iiange and in revolving will come into engagement with the lever d. This lever d is pivoted at the point d to the frame ofthe machine. The upper end of this lever is adapted to come in contact with the upper end of the upright member of the bellcrank lever J. This will rock the bell-crank lever .I and force the gear-wheel K into engagement with the driving-gear L and disengage the gear-Wheel K' from the gear L. This will then reverse the movements by communicating the motion to the gear-Wheel I of the roll E and render the roll E simply an idle roll. When the belt is entirely wound upon the roll E, this operation will be reversed by the rod H being drawn to the outer end of its slot in the fiange F and coming in contact with the lever c, which is pivoted at e to the -main frame, and the upper end of this lever e bears against and is adapted to rock the lever f. This lever f is pivoted concentric with the roll E. This leverf is connected to the upper end or upright member of the bellcrank lever J by means of the spring-linkje upon the outside of the side frame of the machine. This link is connected to the two levers by means of the screws f2, which pass through slots f3 in the frame of the machine and are secured in the two levers. This link f is of spring metal and is adapted to bear against the frame of the machine, so as to cause a certain amount of friction therebetween, which will tend to hold the levers in whichever position they are forced. This Will make the machine entirely automatic, for when the belt has reached its limit in one direction it will reverse the mechanism and cause the belt to travel in the opposite direction, and so on as long as it is desired to opcrate the machine.

The operation of the intermediate motion for displaying the samples is as follows: We will begin and suppose that the sample-belt D is stationary and a sample 'is being displayed. Then roller S2 will be resting upon the periphery of the hub T and the tooth S will be holding the cam-wheel P out of engagement with the driving-gear L, so that the` will raise the tooth S from engagement with the cam-wheel P and allow this cam-Wheel P to spring into engagement with the pins Zon the driving-gear L, and as the cam-wheel P is constantly revolving this will cause the driving-gearL to revolve therewith and communicate to the gear K, and therethrough to the gear l, which has secured to it the roll E-that is, when the gears are in the position shown in Fig. 3. When they are in the position shown in Fig. 7, the motion willbe communicated to the gear K and therethrough to the gear I', which has the roll E secured thereto. This will cause either one or the other roll which is being operated upon to wind the belt thereupon, and this winding will continue until another sample is brought beneath the mirror-box C, and then one of the projectionsV will pass underneath the lever W and force the same outward, and by doing so will communicate the motion to the horizontal lever vZ, which will cause it to assume the position shown in Fig. 5, and this will cause the cam a3 to bear against the iiange T2 upon the'hub T and press the teeth upon the outer face of the hub T into engagement with the teeth upon the clutch member U7, and this clutch member being constantly revolved will ccmmunicate motion to the hub T and cause it to revolve therewith, which will force the roll S? upward out of the recess T and cause the lever S to again assume the position shown in Fig. 3, and the tooth S will thus be forced Within the threads of the cam-wheel P, and this cam-wheel being revolved and being of the nature of a worm will force itself out of engagement with the pins Z upon the drivinggear L, and thus the movement of the gear will be arrested and the sample-belt will be caused to remain stationary until the shaft T has again madea revolution and forced itself out of engagement with the clutch member U'7 and the roller S2 has again dropped within the recess T', when movement would be again commenced, as before described.

In Fig. 7 I have shown a slight modification of the manner of reversing the movement of the sample-belt. edge of the sample-belt from that whereon is fastened the projections V, I secure at each end of the sample-belt a projection g, and upon each side oi' the machine and in the line of travel of these projections I secure the levers h. These leversv are similar to the -lever W, which I use for arresting the movement of the sample-belt. One of'these levers is connected to the lever d by means of the link t', and the other lever h is connected to the lever e by means of the link j. Thus when one of the projections g passes'behind the leverh, as shown in Fig. 7, it will cause the lever e to be rocked, and thus rock the lever f and cause the gear K to mesh with the driving-gear L, as before described, and when the projection g comes behind the other lever h it will cause the leverl d to be rocked, and

Upon the oppositeA IOO IIO

thus force the gear K into mesh with the driving-gear L, and thus again reverse the movement. As will be observed, in the iirstdescribed method of reversing the samplebelt the sample-belt could not be reversed until it had been entirely wound or unwound from either of the rollers; but in the method last described the projections g could be set at any place upon the belt, and whenever they strike the levers h the belt will be reversed. This would be very convenient, as at times certain samples upon the belt might be soiled, so as not to be presentable, or for other reasons it might not be desirable to show them. 'I hese two methods that I have described for reversing the sample-belt might be used in a machine which was Vnot automatic as to the stopping and starting of.the belt-that is to say, a machine that is adapted tobe turned by hand and the belt stopped and started at will.

rollers would be one continuous strip, and the samples would be secured to this belt by being buttoned upon the same or in any other similar manner, so that they could be con veniently removed and others substituted.

Of course this machine need not necessarily be horizontal, as it could be used in any position, either horizontal, oblique, or perpendicular, without causing any change at all in the mechanical construction.

0f course I do not wish to be limited to the exact construction here shown, as slight modiiications could be made without departing rfrom the spirit ot` my invention.
