JONATHAN D. HARVEY AND HENRY L. GOODWIN, OF MINNEAPOLIS, MINNESOTA.

STREET OR STATION INDICATOR.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed May 19, 1913. Serial No. 768,462.

To all whom it may concern.

Be it known that we JONATHAN D. HAR- V131 and HENRY L. GOODWIN, citizens of the United States, residing at Minneapolis, in; the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Street or Station Indicators; and we 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 apper- 12 affords means for limiting the extreme tains to make and use the same.

Our lnvention has for its obgect to provide a simple and highly efficient street and Y statlon' indicator, and to such ends, gen-Q orally stated, the invention conslsts of the novel devices and combinations of devices hereinafter described and defined 1n the claims.

dicate like parts throughout the severalf views.

Referring to the drawings :Figures 1 and 2 are similar views in side elevation showing the improved indicator, some parts being broken away and illustrating the different positions of certain of the parts; Fig.

3 isa.horizontal section taken on the line 00 m on Fig. 5; Fig. 4 is a vertical section taken approximately on the line w m on Fig. 5, some parts being broken away; Fig. 5 is a front elevation of the device with some parts broken away; Fig. 6 is a vertical section taken on the line w w on Fig. 5; Fig. 7 is a section taken on the line m w on Fig. 5; and Fig. 8 is a section taken on the line a a on Fig. 5.

Nearly all of the parts of the mechanism are located within a suitable casing made up, as shown, of a box-like body section 1 and removable section 2. The box section 1 is provided with parallel longitudinally extended inside bearing flanges 3, in which the shafts of four rollers 4, 5, 6 and T are journaled. The roller 4 is the feed roller proper and its shaft 4 is provided with a rigidly secured ratchet wheel 8, preferably having square notches. The roller 5 is a relatively small idle or presser roller, and its shaft 5 is journaled in a bearing fork 9 and in longitudinally extended guide strips 10, which latter are rigidly secured on the bearing flanges 3, so that the said roller 5 is free to move toward and from the feed roller 4. Both of the rollers 4 and 5 are preferably provided with pliable facings, preferably of rubber to give the same better driving friction on the wide faced indicator ribbon 11, which is arranged to run between the same. The yoke 9 is provided with a stem 12, which, as shown, works through a suitable bushing 13 set into one wall of the. case 1. A coiled spring 14 on the stem 12 yieldingly presses the roller 5 toward the roller 4 and against the ribbon 11. A nut 15 on the outer end of the stem inward movement of the roller 5.

The ln'dlcator ribbon 11, upon which the names of the streets or stations are to be printed in a manner well understood, is attached at one end to the'roller 7, and at its other end to the roller 6., The shaft 6 of the roller 6 and the shaft '7 of the roller 7 at In the accompanying drawings which j illustrate the invention, like characters in:

opposite sides of the case, are provided with spur pinions 16 that mesh with spur gears 17, which latter are loose on spindles 18 rigidly anchored to the adjacent bearing flanges 3 and sides of the case 1. Helical springs 19 of the clock spring type, are anchored at their inner ends to the fixed spindles 18, and at their outer ends are attached to studs or lateral projections 20 on the respective loose gears 17. One of the springs 19 exerts a force in the direction tending to cause the roller 6 to wind up the indicator ribbon 11 thereon, and the other spring 19 exerts a force in a reverse direction tending to cause the roller 7 to wind up the said indicator ribbon thereon. The said springs 19, therefore, yieldingly oppose each other and take up slack in the indicator ribbon and keep as much ribbon wound on the one roller or the other, as permitted by movements of the feed roller 4. The said feed roller 4, therefore, may have a constant or unvarying step by step movement, so that the street or station indications on the ribbon may be evenly spaced and will not be afiected by the varying diameter of the ribbon rolls on the rollers 6 and 7 Also, these clock springs may be made long enough to take up and let out a ribbon long enough for the longest route traveled by any ordinary street car or train.

The street or station indications on the ribbon 11 are, in succession, presented in front of asight opening 21 in the front case, which sight opening is preferably covered by glass, to keep the case dust tight,

may be imparted to the feed roller l either automatically, or at will, by a motorman, conductor, or other person. The means shown is designed to be operated by the latter noted way and comprises a vibratory lever 22 pivotally mounted on the shaft r of the feed roller, and provided with a double acting reversible driving pawl 23 for engagement with the ratchet wheel 8.

The numeral 24: indicates a shittable anchor or base of re-action for coiled springs and 26 on the one side, and springs 25 and 26 on the other side. The springs 25 and 25 are attached to the slide at and to the lever 22 while the springs 26 and 26 are attached to said slide and to the revcrsible pawl 23. This slide 24: is, as shown, provided with a long slot that works on pins 27 in one side of the case section 1. A link 28 connects one end of the slide 2% to a reversing lever 29, which is pivotally inounted on the outside of the case, the case being provided with a slot through which the said link 28 is adapted to be set into engagement with either of two notches 30 formed in a latch plate 31, secured on one side of the case, as best shown in Fig. 5. The free end of the pawl-equipped lever 22 through a segmental slot 32 in the case (se particularly Figs. 3, l and 7). The free outer end of said lever 2 is attached to one end of a cord or operating cable 33 which is passed between guide sheaves 34 on one end, and over a guide sheave 35 on the other end of a shifting lever 36 that is intermediately pivoted to the case and is connected by a link 37 to the reversing lever 29. When the reversing lever 29, shifting guide lever 36 and spring anchor 24 are adjusted, as best shown in Figs. 2 and 7, and the operating cable 33 is then pulled and released, the feed roller 4 will be positively rotated in the direction of the arrow marked on the ratchet wheel 8 in Fig. 7 At this time, it will be noted that the springs 25 and 26 are slack, and hence, thrown out of action, while the spring 25 tends to pull the lever 22 toward the left and the spring 26 yieldingly holds the right hand end of the dog 23 in action on the ratchet wheel 8. When the reverse lever 29 is moved to the right and set into engagement with the other notch 30 of the latch plate 31, the spring anchor or slide 24 will be moved toward the right and thereby throw the springs 25 and 26 into action, and give slack to the springs 25 and 26, and thereby throw the latter out of action. Under this reversecondition, a pull and release of the operating cable 33 will cause the feed roller 4 to be rotated in just the reverse direction from that indicated by the arrow marked on Fig. 7. This same shifting movement of the reversing lever 29 throws the shifting guide lever 36 from the position shown in Fig. 2 into the position.

works I shown in Fig. 1, so that under both conditions or adjustments above described, the said cable will always pull the lever 22 against the tension of the spring 25 or 25, as the case may be. Obviously, the spring 26 when under tension, renders operative the right hand end of the reversible pawl 23, while the spring 26 when put under ten sion, throws the left hand end of said pawl into action on the ratchet wheel 8. It should be here noted that the friction produced by the pressure of the roller 5 against or toward the feed roller 4-. and against the indicator ribbon 11, is sufficient to hold the said ribbon in any position in which it may be setagainst the tension of the opposing springs 19. Hence, movements of the said indicator ribbon are dependent entirely upon movements of the said feed roller.

Fig. 4t indicates a gong which is automatically operated to indicate each complete step of movement of the feed roller 4. This gong comprises a small bell 38 secured to a suitable standard 39 on the case 1, and subject to a hammer 4-0 pivoted to a rock shaft 4L1 suitably mounted on the case and provided with an arm 42 that works on the pe riphery of the ratchet wheel 8. The hammer 4L0 will strike the bell 38 whenever the free end of the arm 42 falls into one of the notches of the said ratchet wheel 8, which action takes place at the completion of the full movement of the said feed roller. Hence, anything short of a complete or proper full movement of the feed roller will not operate the gong.
