ADVERTISING ARM-CHAIR.

SPECIFICATION forming part of Letters Patent No. 576,054, dated January 26, 1897. Application filed March 14, 1896. Renewed December 31, 1896. Serial No. 617,675. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS T. HAGAN, a citizen of the United States, residing at -Winchester, in the county of Clark and State of Ken- 5 tucky,have invented new and useful Improvements in Advertising Arm-Chairs, of which .the following is a specification.

This invention relates to that class of advertising mediums or devices which are designed to be arranged in the arms of chairs for the purpose of displaying or exhibiting advertisements placed on a movable carrier composed of a web of flexible material.

The chief object of the present invention I is to provide an advertising arm-chair with new and improved means for effectually dis playing cards, signs, or other advertising matter, the construction being such that the carrier bearing the advertisements is caused to travel whenever the chair-arm is depressed.

The invention also has for its object to provide a chair-arn1 with a web of advertisements which will be wound on a winding-roller and unwound from an unwinding-roll to successively display advertising cards or signs through a sight-opening in the chair-arm until a predetermined time, when the motion of the rollers is reversed and the web is intermittently rewound on the unwinding-roller and unwound from the winding-roller.

The invention also has for its object to provide a chair with a pivoted chair-arm containing a web of advertisements, cards, signs, or other advertisements and mechanism whereby an intermittent motion is imparted to the web by the depression of the pivoted chairarm.

The invention also has for its object to provide new and improved mechanism for reversing the motion of the advertising-web after it has been unwound from one roller and wound on another roller.

To accomplish all these objects, my invention involves the features of construction the combination or arrangement of parts, and the principles of operation hereinafter described and claimed, reference being made to the accompanying drawings, in Which- Figure 1 is a side elevation of an arm-chair provided with my invention. Fig. 2 is a dethe plane of section being on the line 4 4, Fig. 3.

tail plan view of the chair-arm, a portion of the chair-back being shown in section. Fig. 3 is a sectional view taken on the line 3 3, Fig. 4. l Fig. 4 is a horizontal sectional plan view,

Fig. 5 is a detail view of the gear-wheel, pinions, and pawl-tripping lever to more clearly illustratethe devices for reversing the motion of the advertising-web. Fig. 6 is a detail view showing the device for retaining the pawltripping lever in either position to which it is shifted for changing the direction of motion of the advertising-web, and Fig. 7 is a detail plan view of the pawl-trippinglever and the reversing-pinion.

In order to enable those skilled in the art tomake and use my invention, I will now describe the same in detail, referring to the accompanying drawings, wherein The numeral 1 indicates the seat of the armchair, 2 the chair-back, and 3 the front legframe or post, all of which parts may be of any ordinary or suitable construction, according to the style of chair desired, and therefore the chair illustrated in the drawings is only typical of many different constructions or forms of chair to which my invention may be applied.

The chair is provided with a chair-arm 4, which may be of any construction suitable for the purpose in hand and is pivoted at its rear end to the chair-back through the me dium of a suitable pivot-pin 5. The chairarm' is adapted to rise and fall in a vertical plane for the purpose of actuating the mechanism which causes the carrier bearing the advertising cards, signs, or other matter to travel whenever the chair-arm is depressed. The advertising-carrier and the operating mechanism therefor are designed to be arranged in the outer end portion of the chairarm, and for this purpose I prefer to provide a casing or housing 6, havinga sight-opening containing a glass or other transparent medium 7 and secured to or forming part of the chair-arm 4. The casing or housing renders it possible to operatively assemble the mechanism therein and to subsequently attach the same to the chair-arm, but for the purposes of my invention the casing may be regarded as ICO a part of the chair-arm, as obviously the chair-arm could be constructed in any suitable manner with a chamber or compartment in its outer end portion for receiving the carrier and its operatingmechanism, hereinafter explained.

The carrier on which the advertising-cards, signs, or other advertisements are placed is in the form of a web 8, of flexible material, having one end secured to the periphery of an unwinding-roller 9 and its other end sooured to the periphery of a winding-roller 10.

I term therollers 9 and 10, respectively, unwinding ant winding rollers to more clearly distinguish them and to enable the invention to be more clearly understood from the written description, as will hereinafter appear.

The unwinding-roller 9 is hollow or in the form of a tube and is rotatably mounted 011 a non-rotary shaft 12, having its ends secured in the walls of the casing or housing 6. The hollow or tubular roller contains a helical or spiral spring 13, which is attached at one end to the non-rotary shaft and at the other end to the roller for a purpose which will hereinafter appear.

The winding-roller 10 is mounted on a shaft 14,1'otatably mounted in the casing or housing.

The rollers 9 and 10 are of a length approximately coextensive with the width of the advertisingnveb 4E, and preferably the length of the rollers slightly exceeds the width of the web.

As shown in Fig. 4, the bottom wall of the casing is constructed with a pendent tubular extension 15, slidably arranged over the upper end of an arm or lug 16, mounted on the upper end of the leg-frame or front post 3 of the chair in such manner that the outer end portion of the chair-arm can rise and fall to a limited extent on the arm or lug, so that when the chair-arm is depressed the arm or lug will actuate a lever 17, which is geared with and serves to transmit motion to the windingroller 10 for the purpose of winding the advertising-web thereupon and unwinding it from the roller 9. The lever 17 is approximately semicircular in outline and is constructed with a tailpiece, which overhangs the upper end of the arm or lug 16, and with a curved toothed portion, which constitutes a segmental gear 18. The actuating-lever is mounted at or near its center upon a shaft or stud 17*, extending from one wall of the casing or housing 6, and the segmental gear 18 meshes with the teeth of a pinion 19, mounted on a shaft or stud 20.

The pinion 19 is attached to or forms part of a disk 21, provided with a pivoted pawl 22, having a tailpiece 23 and an acting end 21 to engage the teeth of a ratchet-wheel 25, attached to 01.- forming part of a spur-gear or gear-wheel 26, mounted on the shaft or stud 20. The gear-wheel 26 engages the teeth of a pinion 27, keyed or otherwise secured to the shaft 14 of the winding-roller 10, so that if 'rotary motion is imparted to this pinion the shaft and roller will likewise be rotated. The pinion 27 is arranged on the shaft 14 at some distance from one end of the roller 10, as will be seen by reference to Fig. at.

It will be obvious that when the chair-arm is depressed the tail end of the lever 17 is elevated by the action of the arm or lug 16, the pinion 19 and disk 21 are rotated in the direction of the arrow, Fig. 5, and the pawl 22, carried by the disk 21, rotates the ratchetwheel 25 and gear-wheel 26, which latter turns the pinion 27 in the direction of the arrow, Fig. 5, thereby correspondingly turning the roller 10, so that the advertising-web 4 is wound on this roller and unwound from the unwinding-roller 9.

\Vhen the pressure on the chain-arm is re leased, so that it can rise, a spring 28 will act to restore the actuating-lever 17 to its normal position, Fig. 3, and at the same time raise the chair-arm. Owing to the presence of the ratchet-wheel 25 and pawl 22 the movement of the actuating-lever to normal position is rendered possible without imparting rotary motion to the roller 10. This roller is, however, positively prevented from turning backward, except as hereinafter explained with reference to the reversing mechanism, through the medium of a pawl 29, mounted at one end on a pivot-pin 30, and having its other end adapted to lie in the path of a pin 31, secured to and extending from one end of the roller 10. hen this pawl 2 9 is in its normal position, as shown in Fig. 3, its free extremity lies behind the pin 31, and obviously the roller 10 cannot turn backward.

The individual advertising cards or signs on the web are each approximately equal to the circumference of the winding-roller10, so that each revolution of this roller moves the web the distance required to place a card or sign under the sight-opening containing the glass or other transparent medium '7, through which the card or sign is visible and can be read by the person occupying the chair.

These remarks apply under the presumption that different advertising cards or signs are placed upon the web, but obviously a single continuous advertisement can be placed upon the web or upon a portion thereof, and the chair-arm operated to move the web, so that by repeated operations of the chair-arm the entire advertisement can be caused to travel under the glass or other transparent medium through which the advertisement may be read.

7 hen the web is nearly or entirely unwound from the unwinding-roller 9 and wound upon the winding-roller 10, the traversing motion of the web should be reversed, so that it will then be unwound from the winding rollerand wound on the unwinding-roller. This is accomplished through the medium of reverswhen the latter will be stopped at the time it completes a revolution.

The device for tripping the pawl is composed of a duplex armed or bifurcated tripping-lever 32, havingan elastic or spring-tailpiece 33, and its two arms or members 34 and 35, preferably made of unequal length, the arm 35 being the longest and constructed or provided at its extremity with a lateral stud 36, preferably formed by bending or turning the extremity of the arm 35 in a direction laterally toward one end of the roller 10, as best seen in Fig. 4, so that the stud is adapted to be acted upon, as hereinafter explained, by a pin 37, extending from a reversing pinion 38, which is mounted on a stud-shaft 38".

- The arms or members of the tripping-lever 5 are provided, respectively, with trippinglugs or-teeth 34 and 35 for tripping the pawl 22 into and out of engagement with the ratchetwheel 25, as hereinafter explained.

The pinion 27 is provided with a lateral pin 39, which at the completion of each revolution of the pinion engages one of the teeth of the reversing-pinion 38, so that for every revolution of the pinion 27 the pinion 38 advances one step or the space of one tooth.

The teeth of the pinion 38 are engaged by the free extremity of a leaf-spring 40, which permits the pinion to be forcibly rotated, but prevents it from being accidentally moved. The pinion 38 is constructed with a number of teeth, the same as the number of the advertising cards or signs or card-spaces provided on the web 8.

The engagement of the pin 37 on the pinion 38 with the stud 36 of the tripping-lever 32 is designed to occur at the time that the web reaches the end of its travel in either direction. It will be obvious that when the pinion 38 is rotated in the direction of the arrow thereupon in Fig. 3, and the pin 37 strikes the stud 36 of the tripping-lever, the long arm 35 of the latter will be elevated and the lug or tooth 34 on the short arm 34 will be raised out of the path of the tail 23 of the pawl 22, while the lug or tooth 35'" on the arm 35 of the trip-lever will bemoved into the path' of the tail of the pawl, in consequence of which the pawl will be tripped and thrown out of engagement with the ratchet-wheel 25. It is now possible for the motion of the roller 10 to be reversed for the purpose of reversing the motion of the advertising-web.

WVhen the arm 35 of the tripping-lever is elevated by the pin 37 of the pinion 38, as above explained, the elastic tailpiece 33 of the lever lies in engagement with the trip-lever-retaining block 41, which is secured in a fixed position to one of the walls of the easing or housing. This retaining-block 41 is constructed with two reversely-inclined surfaces '42 and 43. When the tripping-lever is in the position shown in Fig. 5, the tailpiece 33 engages the upper inclined surface 42, and when the trip-lever is operated on by the pin 37 to lift the arm 35 of the lever the tailpiece 33 engages the inclined surface 43 of the re-' taining-block. By this means the trippinglever is retained in either position to which shifted; but at the same time it can be operated by the action of the pin 37 on the stud 36.

The reversing-pawl 22 is acted upon by the free extremity of a leaf-spring 44, so conthis lever will act against the under side of the pawl 29 and raise its free end out of thepath of the pin 31 on-the end of the roller 10. At this instant the helical orspiral spring 13 rotates the roller 9, and a stop-finger 46, eX- tending from the pawl 29, is moved into the path of the pin 31, so that when the roller 10 has made a complete revolution the pin 31 will strike the stop-finger 4G and arrest the roller. The stop-finger 46 will hold the pin 31 so long as the chair'arm is held depressed, but when the chair-arm is released the pawl 29 will fall by gravity, and the pin 3l will pass over the extremity of the finger 46 and strike the extremity of the pawl 29. The parts are now in position for a subsequent operation, which is carried int-o effect by depressing the chair-arm, whereupon the operation last above described is repeated, so

that by repeatedly depressing and releasing the chair-arm the advertising-web 8 is unwound from the winding-roller 10 and wound upon the unwinding-roller 9, and when the web is nearly or entirely unwound from the roller 10 the pin 37 of the pinion 38 strikes the stud 36 on the long arm of the trippinglever, thereby depressing this arm 35 and causing the lug or tooth 34 on the arm 34 to move into the path of the tail 23 of the pawl 22, so that the acting end of the latter is i thrown into engagement with the ratchetwheel 25, in consequence of which the reverse motion of the advertising-web is provided for,

and the depressions of the chair-arm will time to depress the arm 35 of the tripping lever and at another time will elevate this arm of the tripping-lever, so that the lugs or teeth 34 and 35 on the arms 34 and 35 of the lever are alternately thrown into and out of the path of the tailpiece on the pawl which is designed to engage and disengage the ratchet-wheel of the spur-wheel or gearwheel which meshes into the pinion on the shaft of the winding-roller.

In the operation of the mechanism the pin 37 of the reversing-pinion 38 never actually passes by the stud 36 on the arm 35 of the tripping lever; but, on the contrary, the pinion 38 immediately reverses its direction of motion after the pin 37 presses against the stud 36 sufficiently to move the same the distance required to throw either of the lugs or teeth 34: and 35 into or out of the path of the tail 011 the pawl of the ratchet-Wheel.

The mechanism described is novel, simple, and efficient, and enables the advertisingweb to be moved in one direction a predetermined time and then automatically reversed to move in the opposite direction, so that the advertisements provided on the web can be repeatedly exposed to view through the glass or sight opening in the upper side of the chair-arm.

It is desirable that the individual cards or signs provided on the web be placed somewhat farther apart toward the end portions of the web in order to compensate for the increasing circumference of the rollers as the web winds upon either one of them, for the purpose of causing all of the cards or signs to be properly presented to view through the glass or sight opening.

The helical or spiral spring 13 tends to rotate the roller 9 in the direction to wind the web on this roller, and when the roller 10 is rotated to wind the web thereupon the draft of the web rotates the roller 9 in opposition to the force of the spring 13, thereby winding the spring and placing it under the required tension for the subsequent rewinding of the web on the roller 9 when the reversing mechanism operates to permit the reverse motion of the parts.
