COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 428,700, dated 'May 27, 1890.

Application iiled February 25, 1890. Serial No. 341333. (No model.) I

T all whom it may concern:

Beit known that we, JAMES W. SNYDER and GUsTAvE H. GRABE, citizens of the United States, residing at Coudersport, in the county of Potter and State of Pennsylvania, .have invented a new and useful Copy-Holder, of which the following is a specification.

rlhis invention has relation to copy-holders, and among the objects in view are to provide a simple and efficient copy-holder adapted to be operated line by line as copied, the holder being operated by a convenient key located at one side of the same.

A further object of the invention is to provide an efficient and convenient means of introducing the manuscript between the feedrolls of the holder, and to avoid any breaking or bending of the same.

With the above objects in view the invention consists in certain features of construction hereinafter specified, and particularly l pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a copy-holder constructed in accordance with our invention. Fig. 2 is a transverse vertical section. Fig. Sis an end elevation. Fig. 4. is a detail in transverse section looking toward the ratchet.

Like numerals of reference indicate like parts in all the figures of the drawings.

l represents any suitable base or standard, and from the opposite ends of the saine there rise slightly-inclined standards 21 which, near their upper ends, are provided with elongated slots 3, and journaled in the same is a roller 4, the trunnions 5 of which rest in the elongated slots and are pressed upon by a bearing-block 6, between which and the upper end of the slot there is interposed a coiled spring 7.

Below the roller/i there is located the feedroller 8, the shaft of which is j-pijojected beyond the standards 2 and at one side provided with a crank 9. The opposite end of the shaft is provided with a ratchet-wheel 10, and said wheel is rigid and moves with the shaft. Beyond said wheel the shaft vis provided with an oscillating disk 1l, said disk being independent of the shaft and provided upon its inner face with a feed-pawl 12, pivoted as at 13, and having its free end engaging the ratchet and maintained in such engagement by means of a curved spring 14 secured to the disk. At one side of the disk there is pivoted to the base, as at l5, a keylever 1G, which near its free end is straddled bya keeper i7, and between the key-lever and 'base there is interposed a iiat spring 1S. A pitinan i9 connects the oscillating disk with the key-lever, and bydepression of said lever the disk is oscillated in one direction, and by the fiat spring under the lever'returned or oscillated in the opposite direction.

It will be apparent from the foregoing description that by a depressionof the key-lever the pawl will serve to rotate the ratchetwheel and the shaft upon which it is mounted one tooth to the rear, which distance agrees with that between the lines of the manuscript, so that for every depression of the keylever the manuscript is fed one line farther to the rear.

20 represents a feed-passage, the rearend of which is provided with laterally-progecting feet 21, secured to the base by screws 22. The feed-passage is open at opposite ends, and the edges at the rear end are iiared, as at 23, so as to receive the manuscript readily. The passage projects forwardly under the rolls, and is curved upwardly, as at 24, forming the letter J in cross-section, the mouth of the same terminating at a point nearly opposite the point of contact of the rolls, so that manuscript introduced into the passage may be pushed forward and will have its upper end guided between the rolls.

By operating the crank the manuscript Amay be fed any distance between the rolls, or byl successive depressions of the key, as before described, the same is fed lineby line.

Having thus described our invention, what we claim is- 1. In a copy-holder, the combination, with opposite standards and opposite rolls, the upper one of which is spring-pressed upon the lower, of a ratchet mounted rigidly upon the shaft of the lower roll, an oscillating disk mounted upon said shaft at one side of the ratchet, a pivoted pawl secured to the disk and meshing with the ratchet, a spring for maintaining the saine in contact with the ratchet, a pivoted key-lever secured to the IOO hase@ Sprngfor raising the sinne, :ind a pitman connecting the key-lever with the oseillating disk, substantially as specified.

2. In a eopy-holder, the combination, with two rolls, the upper one of which is maintained in yielding Contact; with the lower, and means for operating` the rolls, of a :mannseript-passage secured to the hase between the rolls, having si rear flared month and its forward end "upwardly curved in front of the rolls and termina-ting in L point between the Sinne, substantially as specified.

In :L copy-holder, the standards mounted upon the base and carrying the rolls, one of which is spring-pressed, combined with the key-leverpivoted to the base and spring-supportethns shown, ratchet on one of the rolls, and :t disk located upon and rigid with the shaft :md :it one side of the ratchet, and :L

pnwl pivoted to the diek and engaging the rate]iet-connections between the lever and the disk, as Set forth.

Llv. In L oopyholder, the combination, with the two rolls between which the eopy is passed, of the inminseript-pzt5sage in the forni of the letter .I in eross-Seetion, having its base seenred to the base of the copy-holder and its front end curving,- upwardly and terminating at :L point nearly opposite the point of eontaet of the rolls, :is set forth.

In testimony that we claim the foregoing as our own we have hereto aixed our signatures in presence of two witnesses.
