a corporation of Delaware Filed Dec. 10, 1965, Ser. No. 512,919 3 Claims. (Cl. 40104) ABSTRACT OF THE DISCLOSURE The device shown is a title page display unit for use in a remote selector or wall box for a coin-operated phonograph (juke box). In such wall boxes the available display area is small so that all available titles cannot be shown simultaneously. The titles are mounted on pages which can be turned successively under the control of a manually-operated knob. The knob actuates a gear train including a rack acting on successive sector gears, one on each page to be turned.

This invention relates to remote control selectors and more particularly to the title index mechanism for displaying titles of records available for selection therein.

In automatic phonograph or jukebox systems generally in use at the present time, there are available for selection up to 200 records. The titles to these recordings are generally coded into groups of ten or 20. In one approach currently in use, twenty letter groups are employed, with ten numbered record titles per group. In the main phonograph cabinet, the titles are grouped and displayed in a flat plane readily visible to the eye of the viewer. In remote selectors or wall boxes, the available viewing space is comparatively small, so that the title index must be broken up. In the usual form, the index is arrayed in book form with each code group forming a page. The pages are disposed on either side of a rigid panel. In one currently used mechanism, the panels each have an extension rising out of the cabinet, the extension being fitted through an arcuate opening in the cabinet top surface. The extension of a panel is grasped manually and turned through the arc of the opening to expose the other page of the panel being turned and one page of the adjacent panel. This approach has at least one major drawback in that an opening is exposed in the remote selector cabinet into which liquids and small objects may be placed by one bent on mischief.

In another form of remote selector cabinet now in use, half panels are mounted for rotation about a single horizontal axis. A shaft extends along this axis, the shaft being rotated by manually rotatable knobs on each opposed side of the housing. Axially and angularly spaced cams on this shaft are rotated to successively engage axially spaced cam followers on successive title pages to raise or lower the pages about the horizontal axis.

While this mechanism is acceptable, a considerable amount of friction must be generated within the apparatus to hold one or more panels in the raised position. This friction must be overcome to flip the panels in addition to the force of gravity which must also be acted against. The panels must be short in height such that two panels, one above the other, can be viewed at the same time.

The present invention overcomes these difliculties in a simple expedient manner. The title page panels are supported within a housing on individual mountings aligned successively along a horizontal line. Each panel is pivotal about its vertical mounting individually, as will be explained, and each panel once turned is firmly held in the new position.

A manual knob at the top of the housing rotates a driving gear co-axial to the knob; this gear meshes with an idler gear which drives a pinion causing gear rack to move horizontally. A pair of gear teeth are moved linearly by means of the rack to engage individual threetoothed sector gears on the successive pages and pivot the index panels to expose one page of the panel to the viewer. The panels are held in one position or another by both the configuration of the panel and rack structure and also by an overcenter spring holding the panels to their mounting structure. By the construction shown, two adjacent title pages are exposed with an angle slightly greater than between the reading surface to afford a good viewing surface on each title page.

It is, therefore, an object of the invention to provide a new and improved remote selector title index viewing mechanism.

It is a further object to provide a new and improved title page apparatus which exposes two adjacent pages in a wide angle viewing relationship.

The invention both as to its organization and principle of operation, together with further objects and advantages thereof will be best understood by reference to the following specification taken in connection with the drawings in which:

FIGURE 5 is an exploded view in perspective of the gear train and panel mounting structure of the invention;

FIGURE 7 is a front view in perspective of the title page backing plate used herein.

In a remote selector for a jukebox, or automatic phonograph, there is provided means for receiving coins, means for storing credit, means for indicating to the user the record titles available for selection and means for sending credit information to the main phonograph along with the selections made. In addition, such remote selectors may have a speaker or speakers with volume controls and the like. The selector must be sturdy enough to withstand attempts to pilfer the inserted coinage and to withstand minor acts of vandalism.

In FIGURE 1, there is shown a remote selector unit employing the present invention for an automatic phonograph or jukebox system. The remote unit has a housing 10 which may be considered as divided into three vertical sections of which the lowermost is the selection control and auxiliary control area 12 which may include speakers behind the side panels 14. Above the control area is a record title viewing section comprising a rectangular cabinet section 16 with a glass enclosure 18 covering the front and sides of the viewing section. Within the enclosure is visible the record index assembly 19. Surmo-nnted on the cabinet section is a vertically extending coin panel area 20 with various signal bearing indicia 22 at either side of a coin receiving slot 24.

Above the top wall 30 of the cabinet section 16, there is mounted a horizontally disposed, manually rotatable knob 32 for controlling the movement of the panels of the record index assembly 19. Knob 32 is spaced above an embossing 36 which forms a decorative part of top wall 30. The knob is spaced above the embossing 36 and partially hidden beneath the coin panel 20, so that it is freely rotatable but cannot be removed without removal of the panel or dismantling of housing 10. The knob 32 is a thin disc which preferably could be fabricated of clear plastic with spaced finger indentations depressed in an annular pattern in the upper knob surface. In addition, the knob periphery may be serrated, both the serrations and indentations allowing the knob to be easily grasped and rotated.

The knob 32 on rotation selectively exposes successive pages of the record index assembly 19 thereby showing the record titles available for selection and the selection code applicable.

The record index assembly 19 is positioned at the front of the cabinet section 16 within the glass enclosure 18. This record index is positioned to cover the conventional credit indicating mechanism and selection transmission mechanism (both not shown). The record index assembly is mounted on support structure which includes a flat backing plate 42 with side plates 44 extending obliquely from the backing plate. The side plates are disposed with individual included angles of slightly more than 155 between each side and the backing plate. Thus, the included angle between the two side plates at the front of the index is slightly greater than 130. At the bottom edge of backing plate 42 is a panel mounting flange 46 which extends horizontally normal to the backing plate. The backing plate 42, side plates 44, and flange 46 may be formed as an integral unit of suitable sheet metal, as shown in FIG- URE 7.

Fastened to the top edge of the flat backing plate 42 is a top panel mounting plate 50 which is secured to the backing plate through a triangular shaped reinforcing bracket (not shown). Aligned adjacent the front of the panel mounting flange 46 are a series of ten equally spaced bearing holes 54. Similarly aligned along the front of the top panel mounting plate 50 is a like set of bearing holes 56. These bearing mounting holes are used to position and mount therein the individual title hearing panels 60, which combine to form the record index.

Each title bearing panel is fabricated of a flat sheet of material such as sheet metal or formed plastic resin. Each panel has similarly configured title pages on each of its side surfaces. Each of the pages, as employed within the embodiment of the invention shown, has five vertically spaced title card mounts. Each title card mount is bordered on the top, bottom, and inner edge by a bordering frame 62 which may be recessed to support slideably therein a title card as indicated in FIGURE 4 by title card 63. Each of the cards preferably would have an upper and lower title thereon. Suitable indicia is permanently or semi-permanently located on the inner edge frame adjacent each title to indicate the selection code designation representing that title position. T o facilitate the insertion and removal of title cards, the panel 60 may be slotted at the center of bearing area 64. At its outer edge 66, each title bearing area 64 may be notched, as indicated by the reference character 68. In addition, a slide blocking ridge may extend from the bordering frame at the upper and lower extremes of the outer edge 66. Adjacent the ridges 70, the bordering frame 62 may be incised as indicated by numeral 72 to additionally facilitate insertion and removal of title cards.

Along its inner rim 80, each title page is reinforced throughout its title area by the side edge of the bordering frame 62. At both its lower and upper edges along the inner rim 80, the title panel terminates in opposed vertically extending spindles 82. These spindles are sized to fit within opposed bearing holes 54 and holes 56. In this way, a panel 60 will be held vertically upright within the opposed horizontal mounts comprised of the flange 46 and plate 50. Co-axially disposed beneath the upper spindle, each title panel has a three-toothed sector gear 84. The teeth cover approximately 120 of the gear periphery which would have a total of six teeth if complete. Of the three teeth in the sector, the central tooth 86 extends planarly from the title panel with the flanking teeth 88 4 angularly spaced approximately 60 from the central tooth.

Arising from the upper surface of each title panel forwardly of the sector gear 84 is a spring mounting tab 90 of substantially triangular shape with its spring recesses 92 positioned above the upper surface of top mounting plate 50. Each of spring mounting tabs 90 holds the forward end of a tension spring individual to that title panel. The opposed or rearward end of each of these tension springs is aflixed to a dowel pin 102. The individual dowel pins upstand from the mounting plate 50 and each dowel pin is directly behind the bearing hole 56 for its respective panel 60. Since the spring mounting tabs are disposed along the top of the title panel spaced from the upper panel spindles 82, the springs 100 tend to hold the panels individually in an oblique position in an overcenter condition. The panels thus are either held in a first position canted toward one side plate 44 or in a second position canted toward the other side plate.

To turn the panels by means of the manually manipulatable knob 32, there is provided a multiple gear train. Within the gear train there is provided a driving gear co-axially positioned with respect to the knob on a tubular support 112. The knob 32 is spaced from the driving gear 110 by a thrust washer 113 and two annular compression washers 114. A retaining washer 116 holds the driving gear compression washers and knob in a unitary assembly. Within this assembly, the knob and driving gear are normally coupled together in a coupling which can be overridden by rotative force. Thus, this assembly 120, in effect, is productive of a slip clutch effect. The driving gear assembly 120 rides demountably on a vertical stationary pintle 122. The pintle is internally threaded to receive a lock screw which holds the assembly together. The pintle 122 upstands from a horizontal seating plate 124, which, in turn, is spaced above and suitably fastened to the mounting plate 50 by a series of spacer members 126. Thus, the driving gear assembly rides, above the seating plate 124, on pintle 122 which rotatably retains tubular support 112.

In mesh with drive gear 120 is an idler gear 130. The speed ratio of the driver to idler preferably should be approximately at a ratio of 1 to 2.5. The idler gear is affixed to a vertical shaft 132 which extends through both seating plate 124 and top plate 50 and is rotatable within bearing in both plates. Beneath top plate 50, the shaft 132 has aflixed to it a pinion 134 of approximately the same gear pitch diameter as idler gear 130. By this construction, rotation of idler gear causes direct rotation of pinion 134.

Mounted below the line of dowel pins 102, the pinion 134 meshes with a gear rack 143 on a horizontally elongated rack member 140. This rack member is mounted for rectilinear transverse motion, under the effect of the gear train. Rack member is supported within opposed straddle brackets 142. These brackets are suitably aflixed to the outermost edges of mounting plate 50 and depend therefrom to support rack member 140 for rectilinear transverse motion. Along the rear side of member 140 the transverse rack gear 143 extends for about two thirds of the length of member 140. At the transverse center of the opposed or front face of rack member 140, there is a two-toothed partial gear 144. This gear is aligned with and successively engageable with the three-toothed sector gear 84 on each title panel.

Through the previously described gear train, rotation of the knob 32 will elfect rotation of driving gear 110 through their common mounting on shaft 112. Drive gear 110 will mesh with idler gear 130 and rotate it. On rotation of idler gear 130, pinion 134 rotates and meshes with rack 143 of rack member 140 to move it and its partial gear 144 transversely across the line of panel mountings.

Rack member 140 rests and rides within slots 141 in straddle brackets 142. These brackets are inverted, L shaped, and overlap a portion of the panel mounting plate 50 at each of the transverse plate ends and are secured thereto by :a screw 146 in a suitable threaded opening. Since only one screw holds each bracket 142, the bracket is adjustable to position the rack member 140 in a forward-to-rear-sense.

The rack member 140 is in effect a thin rail member extending laterally in the assembly 19 and which has a horizontally reinforcing rib 145 extending rearwardly below the gear rack 143. The rib provides a strengthening member and a bearing surface for travel in horizontal step 150 of slot 141. Above this rib 145, the rack is configured with the line of gear teeth 143 ending a few inches from either transverse end of the member 140. On the front of the member 140 there is a forwardly extending rib 147 extending transversely for the extent of the member 140 to provide support and a bearing surface for travel within a suitable horizontal leg 152 of slot 141 in bracket 142. At the center of the member 140, rib 147 is recessed for approximately in a transverse direction as indicated by reference character 148. Above the recess, a reinforcing block 149 extends for approximately one inch transversely on the member 140. This reinforcing block has mounted thereon symmetrically the two-toothed partial gear 144 which meshes with the successive panel sector gears.

The recess 148 in front rib 147 must be long enough to provide clearance for the inner rim of one title panel as it is being turned. When the recess 148 has been moved transversely from behind the one panel, its inner rim will interfere with the rim edges, if turning of the one panel is attempted. Thus, all panels are locked by front rib 147 and only one panel at a time is allowed clearance to turn, a condition occurring only when that panel is located in front of recess 148.

As mentioned previously, the rack member 140 on linear movement moves its partial gear 144. This linear movement drives the partial gear 144 along a lateral path successively past the panel sector gears to engage successive sector gears and to turn the successive gears and their appurtenant panels. Thus, the line-up of pages is successively changed as successive panels are turned from having their right page exposed to a condition in which their left page becomes exposed. During this movement, the left page of one panel A and the right page of the adjacent panel B are both exposed. Continued movement of gear train will turn the panel B listed above to a condition in which its left page is now exposed and the right page of the next panel C. The panels once turned are held in the new position by interference with the rib 147, as described, and by the action of springs 100.

When the panels 60 have all been turned to a condition in which the end panel is superimposed over the remaining panels within its outermost page exposed, block 149 will strike the inside of the straddle bracket 142 and prevent further lateral travel of the rack member 140. In this position, continued rotation of the knob 32 will cause the driving gear 110 to remain stationary with tubular support 112 rotating within it. Consequently, no rack movement or further panel motion can take place. In this way, the impression of an excessive amount of force on the knob will not cause damage to the mechanism due to this slip arrangement.

Now a description of some of the features of the invention as described, and the reasons for these features will be given. First, referring to the configuration of the gears, three teeth are provided on each sector gear 84 and two teeth are provided on the partial gear 144 on the rack member. When a panel is in one or the other of its stable positions and the panel is the next in line to be turned, the sliding partial gear 144 approaches the flanking tooth 88 which is facing toward the rack member 140. As viewed in FIGURE 6, as the rack member 140 moves in the direction of arrow 170, the leading tooth 162 of the partial gear 144 will first strike the flanking tooth in the space between it and the center tooth, will engage the flanking.

tooth and will begin to rotate the sector gear and its panel in the direction of arrow 172. The trailing tooth 160 of the partial gear will fall into the space between the center tooth 86 and the other flanking tooth and will continue turning of the panel. When the panel is fully turned to a position canted in the position opposite that shown in FIGURE 6, the trailing tooth 168 of the partial gear will leave the sector gear passing under the center tooth of the sector.

During the period of turning movement of a panel, its inner edge rotates in the recess 148 and can be turned. This panel will then be held in the turned condition by its spring and by interference of the front rib 147 which will not allow sulficient clearance for rotation of the inner panel rim. The partial gear on continued transverse movement approaches the sector gear of the adjacent panel and will turn it in the same manner. The panels will be turned successively from an oblique position in which one page is exposed and in which a panel is resting on the panels to one side of it to a position in which its opposite page is exposed and in which the panel is resting on the panels to the other side of it.

With embodiment of the invention shown, the major considerations were based on having the maximum viewing angle for minimum index width. To allow the titles to be readable, it was concluded that twenty titles, ten per page, should be visible at a time. To produce a mechanism which met these considerations, it was found that a sector gear which, if complete, would have six teeth with a diametral pitch of 18. The spacing between centers of the panel mounting spindles 82 are on the order of .4375 inch to maintain clearance between adjacent sector gears 84. The gear rack as used with the exemplary values above has thirty-three teeth extending over about five inches of the length of the rack. The values above are primarily listed to illustrate the comparative relationship of the parts found to be successful in the apparatus.

Another point to be noted is that the record index assembly 19 is mounted in the wall box as a unit and may be removed as such for replacement of panels, and for such other repairs as become necessary. The assembly as a unit includes as its main components the backing plate 42, top mounting plate 50, seating plate 124, rack member 140, panels 60, and bracing rod 164. This rod is secured to cross the entire assembly 19 forward of the mounting plate 50. This rod 164 is affixed to end tongues 166 of the backing plate side plates 44, and reinforces the assembly, allowing the assembly 19 to be handled readily as a unit. Further, this bracing rod may be used to mount the assembly in the housing 10.

When the entire remote control cabinet is mounted on a wall or the like, the viewing window or enclosure 18 is exposed. To gain access to the record index assembly, the outer housing must be removed and the mounting elements for the assembly 19 released. Thus, if desired, the entire assembly 19 could be replaced. For further disassembly, the knob assembly can be removed from pintle 122 by the removal of screw 125.
