Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed September 26, 1904. Serial No. 226,065.

To all whom it may concern:

Be it known that I, PETER'MANUELWISE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Continuous Writing- Tablets; and I 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 appertains to,

make and use the same.

This mvention relates to certain new and useful improvements in mechanisms for feeding a sheet or strip of material automatically upon a writing-surface.

The object of the invention is to construct a simple automatic sheet-feeding mechanism which is efficient in operation, as well as durable in construction. Said mechanism'may be attached to any. existing writing-surface, such as a desk or battery-box, to permit of the paper to be fed thereupon.

Another object of the invention is to improve the construction of adevice which is adapted to automatically feed'a sheet of paper upon a hard surface.

A still further object of the invention is to construct a spring-actuated mechanism, which is manually controlled, for the purpose of supplyinga sheet of material continuously upon a suitable writing-surface. With these and other objects in viewthe invention consists in certain novel constructions.

combinations, and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a view in side elevation of a mechanism constructed in accordance with the present invention. Fig. 2 is an elevated fragmentary front view of the mechanism depicted in Fig. 1.

In carrying out the present invention I have constructed a mechanism which is adapted for the purpose offeedi-ng paper more particularly to the small desk over the battery-box of the usual telephone outfit; but this invention is applicable to any desk, counter, or any place where paper is used for memoranda.

This mechanism is also adapted to be employed as a toilet-paper holder.

Referring to the drawings, 1 designates a casing which comprises in its construction par- '20. The roll 7 is in mounted the gearing mechanism for controlling movement of rolls 5, 6, and 7, which are mounted on the inner vertical plates 3 of the casing 1.

The gearing or spring-motor mechanism comprlses 1n 1ts construction ashaft 8, which "is journaled in plates 2 and 3. Mounted upon shaft 8 is a gear-wheel 9, to which is secured at one of its ends a power-spring 10. The opposite end of the power-spring 10 is secured to shaft 8. An inclosing housing 11 is secured to gear-wheel 9 for the purpose of forming a protecting-casing for spring 10. A shaft 12, upon which is mounted roll '6, is journaled in the parallel plates 2 and 3 above shaft 8 and is provided with a pinion 13, which meshes with cog-wheel 9. A cam 14 is keyed upon shaft 12 adjacent to plate 3 within the compartment 4. A releasekey or dog 15 is journaled upon plate 3 within the compartment4 and is normally held in engagement with cam 14 by means of a spring 16, which is secured at '17 to plate 3 within the compartment 4. The

spring 16 normally engages the upper edge of member 15. The pawl 15 is provided with a toothed or hooked end 18, which is adapted to engage the stop formed upon cam 14' for the prevention of rotary movement thereof.

A largepaper-roll 5 is journaled upon the lowest portion of plates 3 of the casing at 19.

the casing 1, thereby permitting of the inser- The paper-roll 5 is d etachably mounted upon tion of a newroll when the supply of paper 5 has been consumed upon that which is in po sition upon the casing 1. The rubber-coated feed-roll 6 is mounted upon thepaper-roll 5, but is not normally in engagement with the same. A notch 20 is formed upon the upper edge of each plate 3, providing sockets or receiving means for the spindles 21 of the auxiliary feed-r0117. The roll 7 is detachably mounted upon the casing within the sockets frictional engagement with roll 6.

The plates 2 and 3 are provided'with rightangular integral extensions or flanges 22, which are adapted to be secured to the supporting-surface of a desk, battery-box, table, or any similar object. upon which it is desired to feed the paper from roll 5.

A cover, which is shownby dotted lines 24, i

is adapted to be positioned on the casing 1 for entirely closing the rolls of the gearing mechanism. If the cover is positioned .upon the casing 1, it will be necessary to provide-suit- IIO able apertures through which the sheet of,

material which is passed between the rolls 6 and 7 is adapted to be discharged. An aperture also must be formed upon the cover, through which the outer projection of the releasing-key 15 will be permitted to project, so that the operation of the driving mechanism may be controlled from the outside of the casing 1.

When the mechanism is in the position shown in Fig. 1, the same is locked against If it is desired to discharge the sheet from the roll 5 between rolls 6 and 7 and upon the writing-surface, it will be necessary to cause movement of the finger-engaging portion 25, which is threaded at 26 upon the pawl 15, thereby moving said pawl or member 15 upon its pivot, raising the hooked end 18 from engagement with cam 14, permitting of the potential energy stored in the power-spring to be exerted upon the gearwheel 9, consequently causing rotary movement of pinion 13, which is keyed to shaft 12. When rotary movement is imparted to shaft 12, similar movement is also imparted to rolls 6 and 7, respectively. If a sheet of paper is supplied to rolls 6 and 7 and fed between the same, the roll 7, which is in frictional contact with the roll 6', will cause the paper to be fed onto the writing-surface as movement is imparted to shaft 12. As soon as a sufiicient amount of paper has been fed through the rolls 6 and 7 upon a writing-surface or the like to lock the mechanism it will be necessary to release pawl 15, the hooked end 18 of which will be caused 'to move into engagement with cam member 14 and to positively lock shaft 12 against rotary movement as soon as the hooked end 18 comes in contact with the shouldered or projecting portion of cam 14. The locking of the shaft 12 against rotary movement also prevents similar movement of gear-wheel 9, and consequently prevents the exertion of the powerspring to cause movement of the rolls.

When it is desired to wind the spring, it will be necessary to apply at the squared portion 27 of shaft 8 a key or the like for imparting rotary 'movement to the shaft 8. Keyed upon an extension of shaft 8' and between the plate 3 and the paper-roll 5 is a pinion 28, which is normally engaged by the pawl 29. The pawl 29 is pivotally mounted upon the plate 3. Owing to the construction of the pinion 28 and pawl 29, rotary movement is only imparted to shaft 8 in one direction, such movement being manually imparted to shaft 8 by a key or the like.

While I have described in the foregoing description and depicted in the accompanying drawings the preferred construction of my invention, it will be obvious to one versed in the art to which this invention relates that certain alterations, modifications, and changes may be made, and I therefore reserve the right to make such alterations, modifications,

and changes as shall fairly fall within the spirit and scope of the present invention.
