Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed April 20, 1908. Serial No. 428,065.

To all whom t may concern:

Be it known that I, CLAUD OATES F RICK,

a'citizen of the United States, and a resident of Fostoria, in the county of Seneca and State of Ohio, have invented a certain new and useful Station-Indicator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art` to which it appertains to make and use the same, reference being had to t-he accompanying drawings, and to the figures of-reference marked thereon, which form a part of this specification.

My invention relates to registers or indicators of the class particularly adapted for use on street cars or the like for successively indicating the names of streets or stations when reached, but is notrrestricted to such use, as it may be employed for advertising or other purposes in which a band or strip containing reading matter is intermittently moved to successively bring fresh parts of such matter into view.

The primary object -of my invention is the provision in an apparatus of this class of simple and eiiicient mechanism which is operative to positively rotate the master ribbon-roll and the take-up roll in unison at each operation and then to permit the takeup roll to automatically adjust itself to compensate for its gradually increasing size as the ribbon increases in quantity thereon.

Further objects of the invention as well as the operation, arrangement and construct-ion of the parts thereof will be apparent by reference to the followingspecitication, and a preferred embodiment thereof is illustrated in the accompanying drawings, in which,.

Figure 1 is a vertical section of the apparatus taken on the dotted line w x in Fig. 2, with a diagram of an electric operating means and portions of the parts disposed beyond said line also in section. Fig. 2 is a front elevation of one end portion of the apparatus with the front of the casing removed. Fig. 3 is an inner end view of the reversing parts. Fig.4 is an enlarged end view of a portion of the operating mechanism with the latter shown out of normal position. Fig. 5 is a section on the line w' in Fig. 4. Fig. 6 is an enlargedview of one end portion of one of the yieldingly mounted idler-rolls and its mounting, with the latter in longitudinal section. Fig. 7 is an enlarged end view of the master ribbon-roll and the coperating sets of pressure rolls, with the yielding connection of the latter, and Fig. 8 is an enlarged view of av switchpoint and a portion of the rail by which it is carried.

Referring to the drawings, 1 designates the casing or housing in which the mechanism comprising my invention is mounted, and' 2 the opening in the front thereof through which the matter on the ribbon is displayed. Disposed transversely of the casing immediately in rear of the opening 2 with its trunnions or shaft ends 3' suitably journaled in the casing sides is the master ribbon-roll 3 around a part of which the ribbon or belt 4 containing the matter to be displayed passes. The ribbon 4 has its ends attached to and is adapted to wind from one to the other of the rolls 5 and 5' which are mounted transversely of the casing in planes, respectively, above and below the masterroll 3 as shown. The ribbon on leaving, for instance, the upper roll 5, passes around the yieldingly mounted idler-roll 6, thence under the idler-roll 7 at the rear of the roll 3, after which it passes around the roll 3 and over the idler-roll 7', which is disposed at the rear of the roll 3 in contiguous position to the companion idler 7, thence around the yieldingly mounted idler-roll 6' and to the other ribbon-roll 5', as shown. Each idler 6, 6' has its trunnions journaled in blocks or cross-heads S, which are mounted in guides 9 for movement longitudinally thereof, the trunnionsworking through registering slots 10 therein for such purpose. The guides 9 are fixed to opposite sides of the casing and are preferably disposed so that the ribbon in passing around the idlers thereof is caused to make decided loops between the rolls 5, 7 and 5', 7', respectively, as shown. The block 8 in each guide is yieldingly held in extended position relative to its roll 5 or 5' by a compression-spring 11, which is mounted within the guide, as shown. The ribbon 4 is held closely to the master-roll 3 by the pressure-rolls 12, which are shown as being arranged in sets at the upper and lower sides of the roll 3. The rolls 12 of each set are transversely connected at their ends by yokes 13, which carry blocks '14 for working in slots or guide-ways 15 in the opposite endportions of the members 16. These members are disposed diametrically of the end.o

of the roll 3, being loosely carried by the trunnions thereof, and are provided with contraction-springs 17, which attach at their outer ends to the blocks 14 and act to yieldingly draw the rolls 12 to the roll 3. As the mechanisms for moving the ribbon in opposite directions are duplicates, only one will be described in detail, and it will be understood lthat like parts of the two are designated by like numerals except that the numerals of one have the prime mark added.

Fixed to the roll 5 at one end thereof is the spur-gear 18, which meshes with the larger gear 19 that is carried by the stubshaft 20 and has the ratchet-wheel 21 fixed to one side thereof, said stub-shaft having one end j ournaled in the casingd side and its other end journaled in a bracket 22 projecting from the casing, as shown.

23 designates a reciprocatory rod, which has its forward end working through a suitable bearing in the casing front and its rear end portion preferably provided with a piston and working through a dash-pot 24, which tends to retard the movements of the rod in either direction. The dash-pot 24 is carried at the upper end of the vertical yoke 25, which is fixed to the casing side by brackets 26, or in any other suitable manner, and carries the dash-pot 24 of the other mechanism at its lower end, as shown. rFhe rod 23 is normally retained at its limit of forward movement by the action thereon of a compression-spring 27, which is mounted within the dash-pot 24, and has rearward movements imparted thereto by the means hereinafter described or in any other suitable manner. Secured to theV forward end portion of the rod and adapted to coact with the casing front to limit the forward movement of the rod is the cross-piece 28, which pivotally carries the rearwardly projecting arms 29 and 30 at its oppo-site ends. These arms are normally held in contracted relation by the contraction-spring 31 and carry the peripherally grooved wheels 32 and 33, respectively, at their free ends.

Fixed below the ratchet-wheel 21 are the two spaced rails or tracks 34 and 35, which are curved to stand in concentric relation to each other and to the axis of the ratchetwheel. The inner rail 35 has its ends terminating short of the ends of the rail 34, and is provided at its forward end with a pivotal switch-point 36, which is normally infiuenced by a spring 37, or in any other suitable manner, to stand with its point in yielding Contact with the inner face of the rail 34 short of its forward end, as shown. Disposed above a ratchet-wheel 38, which is carried at an end of the roll 3 on the shaft therewith, is a similar arrangement of rails or tracks 39 and 40, which are spaced relative to each other and stand in concentric relation to the axis Vof the ratchet-wheel.

The inner or shorter one of these rails is provided at its forward end with a pivotal switch-point 41, which is influenced to normally have contact at its point with the track 39 near its forward end, as shown.

When the rod 23 is in its normal :1t-rest position the wheels 32 and 33 engage the inner curved faces of the rails 34 and 39, respectively, in advance of the associated switch-points 36 and 41, as shown in Fig. 1, being yieldingly held thereto by the action of the spring 31. On a rearward movement of the rod 23 the wheels 32 and 33 come in contact with and are guided by the switchpoints 3G and 41 to the inner rails35 and 40, respectively. As the wheels 32 and 33 move into engagement with their respective rails 35 and 40 a pawl 42, carried at the free end of the arm 29, engages a. tooth on the ratchet-wheel 21 while a pawl 43 at the free end of the arm 30 engages a tooth in the ratchet-wheel 38, thus importing partial rotation to both said ratchet-wheels during the period of movement of the wheels 32 and 33 on the inner rails 35 and 40, respectively. When the rod 23 has reached its limit of rearward movement the wheels 32 and 33 leave the rear ends of the rails 35 and 40 and are drawn by the action of the contraction spring 31 into contact with the projected rear ends of the outer rails 34 and 39 by which they are guided to return to their normal positions on the forward movement of the rod 23, with their pawls free from contact with the two ratchets. As the wheels on their return movements come in contact with the switch-points 36 and 41 said points move inwardly against. the tension of their springs to permit the wheels to pass in advance thereof in readiness to be again directed to the rails and 40 when the rod is next moved to the rear.

44 designates a rock-shaft, which has one end journaled in the center of the yoke 25 and its other end journaled in the rear of the casing 1. Feathered for movement longitudinally of this shaft intermediate its bearings is the sleeve 45, which is provided at its forward end with the two oppositely extending arms 4G, 4G', one of which is adapted to coact with the forward side of a button 47 on the rear end of the rod 23 and the other with a button 47 on the rear end of the rod 23', as shown. The .arms 4G, 4G are slightly angled relative to each other, as shown in Fig. 3, to enable both to be placed in neutral positions relative to the buttons 47 and 47 or either arm moved into position to engage its button by a rocking of the shaft 44 in the proper direction, so that rearward movement may be communicated to either rod 23, 23 when the sleeve is reciprocated. The rocking adjustment of the shaft 44 is controlled by an arm 48, which is fixed to the shaft end without the casing and carries a snap-pin 49 at its free end forengaging holes or depressions in the casing to retain the arm in set position.

A simple and etlicient means for imparting intermittent reciprocatory movements to the sleeve 45 and connected parts consists in providing a solenoid 50 within the casing, the core of which is connected to the sleeve 45 through the medium of the link 51, lever 52 and link 53, said lever being fulcrumed to a stud projecting from the casing side, as at y54. One terminal of the solenoid coil may be grounded through a wire 55, which may have a switch 56 in circuit therewith, while the other terminal connects through a wire 57 with a contact-linger or brush 58, which is carried by the trolley-pole 59 in position to have contact with contact-pieces 60 arranged at suitable points along the side of the trolley-wire 61. It is thus apparent that when the switch 56 is closed andthe brush 58 makes contact with a contact-piece 60 a circuit to the solenoid is closed, thereby energizing it and imparting the requisite movement to its core and attached parts to move the sleeve 45 and rod 23 or 23 with which it has engagement to the rear, which position is maintained until the brush breaks contact with the piece 60.

The operation of my invention is as follows On a rearward movement of the rod 23, when the solenoid is energized and the arm 46 of the sleeve 45 is in contact rwith the button 47 of such rod, the wheels 32 and 33 carried by the arms 29 and 30, respectively, are directed by the switch-points 36 and 41 to the inner rails 35 and 40 so that the `pawls 42 and 43, carried, respectively by said arms, engage the teeth on the ratchetwheels 21 and 38 and impart equal movements thereto in opposite directions of rotation. The meshing ofthe gear 19, which is fixed to the side of theratchet-wheel, with the smaller gear 18 at the end of the ribbonroll 5, causes said roll to rotate at a greater speed than the master-roll 3 to partially compensate for the diierence in size of said rolls. As the ribbon winds on theroll 5 thegradually increasing-diameter of said roll causes the speed of movement of the ribbon to increase in the same proportion, thus causing a constantly changing variance between the speed at which the ribbon is wound on the roll 5 and that at which it` is paid out by theV master-roll. This dierence in speed of the rolls 3 and 5l is compensated for, so as to prevent a slipping of theribbon on the former, by the permissible shortening of the loop in the ribbon which is formed by passing the ribbon over the yieldingly mounted idler-roll 6. When the wheels 32 and 33, substantially reach their limits of rearward movements they pass around the rear ends of the respective rails 35 and 40 into engagement with the rails 34 and 39 on which they return to their normal positions. As the wheels thus pass from one rail to the other at their limits of rearward movements the pawls 42 and 43 move out of engagement with the ratchet 21 and gear 38, respectively, thus permitting the roll 5, which, together with the meshing gears 18 and 1S) and ratchet 21, is now free to turn, to unwind suiiiciently to allow the idler-roll 6, under the influence of the springs 1l, to return to normal position. It is thus apparent that both the master-roll 3 and take-up roll 5 have positive rotation imparted to them at each rearward movement of the rod 23, and that the variations in the winding of the ribbon on the roll 5 is compensated for by the yielding tendency of the idler 6, thereby preventing a slippingof the ribbon on the masterroll and insuring a positive registering of each name or other matter on the ribbon with the display opening 2 in the casing front in either direction of movement of the ribbon. When the end of the line is reached the direction of movement of the ribbon is reversed by simply moving the arm 48 so as to rock the shaft 44 to throw the arm 46 out of engagement with its button on the rod 23 and the arm 46 into engagementwith its button on the rod 23, thus throwing the lower instead of the upper operating mechanism into commission.
