memory so that he may speak uninterrupt-v i edly without fear of being en'ibarrassed by a loss of memory as to the text of his address. yThe invention seeks to provide a reminder mechanism which will be under control of thel speaker at all times and which will be so disposed as not to be visible to the audience. The invention also has for its object the provision of means whereby the device will be operated efficiently at all times and will not be apt to get out of order. The inventionresides in certain novel features` which will be hereinafter first fully described and then more particularly pointedr out in the appended claim.

In the drawings, which illustrate one embodiment ofthe invention,

Figure 1 is a vertical sectional elevation of a portion of an assembly hall having my invention included therein;

kFigl 2 is an ,enlarged detail perspective view showing the arrangement of the op-v erating parts of the invention;

Fig. 3 is an enlarged sectional elevation of the display cabinet with the door thereof in open position;

f Fig. 4 is a central longitudinal section through the cabinet with the door in closed position;

Fig. 5 is an enlarged detail section of part ofthe means for supporting the display strip or web, and

F ig. 6 is anenlarged detail view of a supporting bracket and portion of the gears carried thereby.

In the drawings, the reference numeral 1 indicates a platform or stage upon which a speaker will stand when delivering an address or lecture, a desk 2 being erected at the front of the platform and being equipped with a vertical rail 3 at its front side which projects above the top 4 thereof. Above the platform 1 is a roof 5 which may be a part of the roof of the building in which the platform is located, or may be the entire roof when the platform is located for open air speaking. The roof projects beyond the front of the platform, as shown at 6, whereby to overhang the desk 2, and at the front of the roof is a rail or other support 7 which is preferably at such height that it may be easily observed by the speaker upon the serieu No. 51,847.

platform 1 but will not attract the atten- "ion the audience seated or standing' in `ront of the platform. Secured to the rail ay, furthermore, constitute a part o the eaves of the roof 5, is a cabinet 8 luwing a swinging door 9 provided with a sight opening 10, the door being normally closed so that matter within the cabinet may be easily seen through the opening 10l by the speaker. rFhe platform and the desk may be illuminated in any desired manner and the greatest eiiiciency will be attained by providing lamps 11 upon the under side of kthe roof 5 immediately over the cabinet 8 "at the sight opening 10 thereof will be ectiy lighted and matter appearing back ci. 'the sight opening, therefore, easily read. iivithin the cabinet are supported

rollers

12 and 18 and carried by these rollers is a web 14 upon which has been previously printed notes of the lecture or address to be delivered, or, .if desired', the entire text of the address. These rollers are provided with longitudinal slits 15 in which the ends of the web are engaged so that, if the rollers be rotated, the length of the web will be wound thereon and, consequently, the ends will be held in the respective slits, it being understood, of course, that the web in practice is found upon one roller and then transferred from the same to the other roller as the delivery proceeds. The lower roller 13 initially carries the entire length of the web 14, except so much thereof as is needed to securely engage it with the upper roller 12, the intermediate portion of the web assing over a supporting plate 16 which isA disposed immediately adjacent the sight opening 10 and has its upper and lower edges made convex so 'that vthe web may pass smoothly an1 easily over the backing plate without liability of tearing.

rlhe rollers

12 and 13 are, of course, assembled so as to facilitate the placing of a web thereon or the removal of a, web therefrom and to support the lower roller in its proper position a stud 17 is secured upon one side of the cabinet to engage a soci-:et in the adjacent end of the roller, as will be understood upon reference tov Fig. 3. the opposite end of the roller, a resilient het 18 is secured in the cabinet to bear against the end of the roller yand hold itin engagement with the stud 17 while a pin or stud l) is engaged in the bore or socket in the roller and passes throughthe free end portieri of the said bracket 18, as shown Leiafrri clearly in Fig. 5. rhis pin or stud i9 has an enlarged socketed outer end 2O which is engaged by the inner end or stein 2l passing through the wall oit the cabinet and equipped at its outer end with head 22. Si spring 23 is coiled around the stein 2l between the side et the cabinet and the socket so as to hold the socket toward the l racket and thereby yieldably maintain the pin or stud 19 in en` gageinent with the roller. Tilhen it is desired to release the roller, an outward pull upon the head 22 will obviously withdraw the pin 19 and permit the roller to be disengaged troni the stud li' and withdrawn from the cabinet. 'llie upper roller l2 is supported at one end by a second stein 2l and stud 19 but the opposite end thereolI is termed with spaced sockets 2l to be engaged by spaced studs upon a head or disk which is disposed at the inner end of a hub 26 which passes through and is rotatably engaged in the side wall of the' cabinet. the outer end oi the hub is provided with a socket 2T having hat walls to be engaged by the tiat sided end 2S of an operating shaft 29.

The shalt 29 is supported in suitable bearing brackets 'upon the rail oi' beam 7 and ei:- tends to the side or the arch or proscenium opening in trent or the platform, a beveled pinion 30 being secured upon the outer end of the said shalt to mesa with a similar beveled pinion 3l upon the front end ot ashatt 32 which entends along the side et the arch to a point in the vertical plane of the desk 2, being` equipped at its rear enti with a beveled pinion corresponding to the pinions 8O and 3l and meshing with a beveled pinion 3st upon the upper end et a shalt 35 which is disposed vertically the side et the prosceniuni opening and entends downwardly to a point just above the desk, as shown. rl"he lower end or the shaft 35 carries a beveled pinion 3G meshing with a beveled pinion 3T secured upon the end by a roller or hand-controlled shaft. 88 which extends across the top of the desk 2 behind the rail 3 thereof so that it will be hidden from the audience by the said rail, Bearing brackets, such as 39, ar secured upon the side oi the arch immediately adjacent the roof so as to support the adjacent ends et the

shafts

29, 32 ano 35, and these brackets also provide the bearings in which the ends of said shafts will revolve. fit the lower end ot the shaft 35 and the adjacent end ot the controlling` roller 3S, a bracket- Ll0 is secured upon the desk and this bracket has an upstanding resilient end ineaber Lil which supports the end oit the roller 38, and an outwardly turned overhanging lip the upper end of the upstanding member, the said lip furnishing bearing and support lor the lower end of the shaft r4Ehe form of brackets employed serve to maintain the meshing pinions in their operative relation while at the saine time they are very simple and inexpensive and may be very easily secured iu place.

To maintain the web taut between the rollers l2 and i3 and prevent excessive .wound from said roller the controlling roller or shalt 238 is rotated, this movement wiil be arrested and it will be held taut and smooth upon 'the siipporting plate l5 instantly when the action ot the controlling` roller stops.

hroin the foregoing description, taken in connection with thc accon'ipanying drawings, it is thought the manner or using my apparatus and the advantages of the saine will be readily understood and api eciated 'D 'lic speakers are t.' ntiy embarrassed because, in the course o't their remarks, they depart more or less troni the pre-arranged text and upon returning to the original theme lind that they have forgo-tten the prepared text immediately itollowing that which preceded the digiession. litany lecturers or public speakers are enabled to :t'ollow the pre-arranged argument by reference to short nieniorantia or notes, but other speakers are obliged to closely tolle i the original tent in order to maintain the sequence et their discourse. lily invention provides means whereby a speaker may have at hand means entirely under his control whereby proper reminders oit the tent will be constantly betore him and embarrassing interruptions in delivery will be avoided. Prior to the opening et the lecture hall the web, having the address printed or written thereon, is placed in the cabinet and mounted upon the rollers l2 and 13 in such position that the text may be easily read by the speaker through the sight opening lO while, et course, the audience will not be able to see the cabinet nor any ot the motion transmitting shafts, inasinuch as the decorations oia the platform and the opening through which the audience views the plattorin and the speakers thereon may be so arranged to completely hide all et the working parts. The speaker will, of course, be delivering the greater portion of his address immediately behind the desk and' may rotate the shaft or roller 38 by one hand as he needs to consult the prepared tex. Should he digress from the pre-arranged matter, the controlling roller 38 will be pern initted to remain stationary during the impromptu remarks, and when it is desired to resume the original discourse, a glance at the cabinet will show the speaker how and where to proceed.

My apparatus is exceedingly simple and compact and may be easily installed in any place intended for public assemblies. It will be understood. that the Asight opening in the cabinet will be glazed in order to protect the text carrying web, and, preferably, a magnifying glass will be employed for this purpose in order that distance between the speaker and the cabinet will not prevent the ready reading of the matter appearing upon the web.

Having thus described the invention, I claim:

Means for prompting a speaker comprising in combination with a desk, and a roof overhanging the desk and having a depending portion forwardlyfof the desk, of a cabinet mounted upon the depending portion of the roof and having a sight opening in its rear side, a prompting web, rollers within the cabinet above and below the sight opening thereof, one of the rollers having the said web Wound thereon, a shafting connected with the other roller and having a p0rtion extending along `the said desk for rotation by the speaker to unwind the web from Vone roller and wind it upon the other roller.

In testimony whereof I ailix my signature.
