To all 'whomit may 'concern-f Be it k' own that I, -ARCHIE N. JOHNSON, a citizen of the United States, and a resident of Kansas City, in the.. county of Jackson and State of Missouri, have invented a new and Improved Moving Sign, of whlch the following is a full, clear, and. exact descrlp- This invention relates to advertisin devices or `signs such as used in public p aces.

More particularly, the invention relates to an advertising device tobe used in street cars, and the object of the invention is to provide an arrangement whereby a number of advertising cards may be displayed on an endless web. These cards are advanced intermittently so that they move progressively along a frame. In this wa made to have periods of rest in successive frames. After a complete cycle all of the advertising cards on the web will have been presented to view.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. I

Reference is vto be had to the accompanying drawings formingv a part of this specification, in which similar characters .of reference'indicate corresponding parts in all the figures.

Figure 1 isa perspective of the device partly broken away and illustrating by dotted lines the manner in which it is mounted in the street cars; Fig. 2 is a vert-ical cross section throu h the device taken substan: tially on thelr and the arrangement for adjusting the position of the advertising frame; Fig. 3 is a front elevation of the advertising evice, a portion of the mechanism vbeing broken away and shown in cross section on the line 3 3 of Fig. 4, this view further illustratin the driving mechanism; Fi 4 is a vertic'a section on the line 4-4 of Fig. 3 an`d further illustrating the driving mechanism; and Fig. 5 is a ldetail showing a portion of the mechanism in plan and illustratin especially the means for holding one of t e rollers in position. a

Referring more particularly tothe parts,v

1 re resents the case of the machine, which is a apted to be mounted in the u per part of a ca'r and near oneend thereo as indithe cards are ine 2-2 of Fig. 1, and illusouter end of the case 1, a frame trating particularly the driving mechanism cated in Fig. '1. AAs shown in Figs. 2 to 4, within this case there is provided a bracket 2 having a" horizontal pivot pin 3, upon which a worm wheel 4 is rotatably mounted. The pin 3 projects beyond the worm wheel 4, and the projecting end is provided with an adjusting bracket 5 mounted A loosely thereupon, as shown. This adjusting bracket 5 has an arm which extends downwardly and presents a laterally projecting quadrant 6. This quadrant is provided with adjusting openings 7 which enable the adjusting frame to be held in any desired position by means of a removable pin 8, mounted in the lower `part of the bracket- 2, as shown in Figs. 3 and 4. The lower part of the adjusting bracket 5 is provided with a vhorizontally projecting arm 9. The up r end of the adjusting bracket 5 is providid with a horizontally projecting arm 10 which is substantially parallel with the arm 9, andl this arm is doubled vback uponitself so as4 wheel 12 is rotatably mounted, said gear.

Wheel being frmed integrally with a bevel gear wheel 13. On the face of the worm wheel 4, adjacent to the gear 12, a bevel gear segment 14 is formed which meshes with the bevel gear 13, as shown. In the'ends ofthe arms 9, 10, and 11, the spindle 15 of a roller 16 is rotatably mounted, said spindle being provided at its upper end with ay inion 17 which meshes with the aforesai gear wheel 12.

Extending longitudinally of the car at the 18 is provided, and in the end of this frame remote from the case 1, -a roller 19 is rotatably.

mounted, the spindle 21 of thesaid roller 19 lbeing mounted in brackets 20 attached to the outerside .of the frame, as shown. The spindles 15 and 21 are providedu respectively with sprocket wheels, 22 and 23, and `over these sprocket wheels a sprocket. chain 24 passes, as shown. The rollers 16v and 19 are connected by a web or endless belt 25, and this belt is divided into advertising cards or spaces upon which advertising literature is printed. The frame 18 is open on its forward side, lbut presents vertically disposed bars 26 which divide the entirev length of the frame into spaces corresponding to the lengths of the advertising spaces or cards of the web. The rear side'of the case 1 is prare presented in turn to view.

engages the bevel gear vof the'frame'will be determined upon and vided with adoor 27 which is mounted on hin es 28 so that it maybe opened when deslre y 4 The upper end of theV spindle 15 does not pass through simple openings 1n the arms 10 and 11, but instead of openings at this point I provide deeplnotches 29, as indicated in Fig. 5, and the notch in the upper arm11 is provided with a transverse locking pin 30 which holds the spindle inposition, as indicated.

In the forward part ofthe case 1, a motor, such as an electric motor 31. is mounted, as' shown. The shaft 32 of this motor extends transversely under the Worm Wheel 4, and is provided with a worm 33 which meshes with the worm wheel, as' indicated. This motor 31 may be driven from a shunt from the 'trolley current, or it may be driven if de' sired from an independent source of current. In the operation of the device the motor 31 runs continuously and operates to drive the worm wheel 4 continuously. At each revolution of the worm wheel 4, the segment 14 13 and rotates the pinion 17 and the spindle 15; this rotates the .roller 16 and advances the web through one advertising space,vthat is, the card displayed in the firstadvertising space will be advanced to the neit advertislng space. The motion im arted to the web 1s just suffi* cient to a vance each card from one space to the next, and during the periods that the se ment 14 is not in mesh with the gear w eel 13, the web is left at rest. In this Way the advertisements are presented in successionV in the small frames ofthe large frame, andl the advertisements on the Vback ofthe web The quadrant 6 enables the angle or incli-` nation ofthe 'web to be adjusted as desired; the limit of its inclination is. indicated in 2. In practice the desired inclination the frame 18 will then be constructed and Aattached toV the case 1 with a'corresponding inclination: A l

' Having thus. 'described myinvention I claim as new and desire secure by Letters Patent,-`-
