BENJAMIN LIVERMORE, OF HARTLAND, VERMONT.

DEVICE FOR, H AND-PRINTlNG.

Specification forming part of Letters Patent No. 39.296, dated July 21, 1863.

To all whom it may concern:

Be it known that I, BENJAMIN LIvERMoRE, of Hartland, in the county of Windsor and State of Vermont, have invented a new and improved Hand-Printing Device or Mechanical Typographer; and I do hereby declare that the following is. a full, clear, and exact description of the same, reference being had to enlarged face view of the combination-type;

Fig. 5, a view of the alphabet, as formed by the combination-type.

Similar letters of reference indicate corresponding parts in the several figures.

' The object of this invention is to obtain a portable device which may be held in the hand .and operated with the greatest facility for printing direct upon paper or other suitable material.

To this end the invention consists in the employment or use of a combination-typethat is to say, a type composed of several sections, arranged andcombined in such a manner that .any oneof the sections may be used separately, and certain parts used combined, in order to form the dii'erent letters ofthe alphabet, as hereinafter set forth. 4

The invention also consists in the employ ment or use of finger pieces or keys, arranged in a novel way withlevers, for the purpose of operating the several parts of the type, and also in a certain means employed for causing the type to traverse or move so that proper v spaces may be allowed between the impressions, and the type allowed to adjust itself properly "at the termina-tion of each line for the printing of a succeeding one.

The invention further consists in a means employed for moving or feeding the paper. along at the termination of each line as it is printed.

To enable those skilled in the art to fully' understand,.construct, and use my invention, l will proceed to describe it.

A represents-a metal case, in which the working parts 1 of the device are fitted. This caseat one' end, a, is -of semi-cylindrical form,

and within 'said part a a cylinder, b,is placed,

on which the paper c,to be printed upon, is wound as it is -printed upon. (See Figs. 1 and 2.)- f

B is a plate, which is placedon'the bottom of the case A, and is secured thereto, at its outer end, by a rivet, d, on which the plate B is allowed to work freely.

C is a curved rack-bar,which is permanently secured to the bottolm of the caseA, and underneath which the plate Bis allowed to work freely, the bar C having its rank on its concave edge. On the plate B there is securedl by a fulcrum-pin, e, a bent lever, D, which is acted upon by a spring, j', and has a pawl,E, attached to it by a pivot, g. 4This pawl has two prongs, h'h/,ne of which,h, engages with the rack-bar C. The use of the other prong, h', will be presently shown.

F is a holding-pawl,whichengages with the rack-bar G and'is provided with au arm, i, which has a projection, j, nearjts outer end, as shown in Fig. 1. The pawl E is actedupon by a spring, k, whichkeeps it engaged .with the rack-bari), and the holdingpawl Fis acted upon by a spring, l, which performs a like oce.

From the above description it will be seen that by forcing or pressing the longer arm of 'the lever D. inward or toward the cylinder b,

that the pawl E will be raised and'slipovera tooth of the bar C, and when Asaid leveris relieved of the pressure the spring f will throw the lever D back to its original position, and the inner end of the plate B will be raised in consequence of the pawl E catching intothe rack-bar. The inper end of theplate B is thus elevated from the lower to the upper edge of the case A, the latter, when tbe device is in use, being held-in an inclined position in the hand of the operator. When the plate B has reached the upper, end of the ease A, the

prong h, which vifs the pawl E proper, passes over a projecting part, m, on the rack-.bar and causes the prong 71.' to act against. the projection 7 on the arm 1', and throntthe holdingpa'wl Font from the rack-bar (l, and admit of the plate B falling, by its own gravity, to the levers, l1, are fitted on a conunon fulcrumpin, tm'. lhe form ot these levers is clearly shown in Fig'. 2.-

l represents what l term a "combination type. It is formed of six diti'erent. parts, designated by l 1', 2 2', and 3 3'. as shown in Fig. 4. '.lbepartsl l' and 2 2' i'orm a hollow square, while the parts 3',3', are ot' V form and within said square, 3' beingl inverted andha-ving its angle adjoining the angle ot'3, as shown clearly in Fig. 4. By means ot' these six parts the alphabet is formed, as shown in Fig'. 5. 1`hepart 3' when pressed against the paper forms the letter A. 3', 3.',`and 2 form the letter 1%; 3, 2,and 1',the1etterb; 3",1', and 2', the letter-l.) 1, 1', and 2, the. letter E; 2 and ],.the letter F; 3', 2,`and l, thc letter G; 3 and 2, the letter l1; 2, the letter l; 1.l and 2', the letter J; 3, 3', and 2, the letter K; 2 and 1 the letter L; 3, 2, and 2', the letter M; l, 2, and 2', the letter N; l, l' 2, and 2', the letter 0; 3, 1. and-2, the letter P; 3, 1, and 2', the let- 'errQ; 3 and 2, the letter lt.; 1, 2', and 3', the

letter S; 1 and 3", the letter 1; 2, 2', and 1', the letter U; 3,theletter V; 3',2, and 2', the letter W; 3 and 3', the letter X.; 3 and 1',the letter Y; 1, 1', and 2', the letter 7. 'l`he levers H are connected one to each ofthe parts ot' the type, as shown at ln, in lfig. 2. and each lever H at its lowervcnd is provided with a pin, o, said pins projecting laterally from one lside ofthe levers. The position of these pins ted over the pins o of the levers H, and the inner notches, 1', arettted in the notchedledge q. The notchesr are made sniiieiently wide to admit of the arms K having acertain degree ot' play on the ledge q, as will be seen by referring to Fig. 2. rllhe. outer ends of the narms Kl are connected by pivots s to levers t,

which have their fulcra u at opposite sides of the case A, there heilig a. lever, t, for each. arm K, and each lever t has a key or finger-piece, L, attached 'to it, each of which is marked corresponding to the part of the typewith which it is connected through the `...edinm ot' the le-A ver AThe pivots s of -the levers t are about in line with the pivot or rivet d ot' the plate i. -ly pressing` inward any one of the keys or iinger-pieces l1,the part ot' the type. l which is connected with it will be raised, andinst pre.- vioustothis, by theback ward movement of the key, the plate B was raised one notch in the barC, to admit. ota propel-space beingI between .th-e letters or impressions on the paper. lhe paper c to be printed upon passes over the type I upon the cylinder b i'rom a roller, M, which basa spring, r, bearing upon it to prevent iti'rom casually turning. A

Nrepresents a pad, which is saturated with -ink or coloring material. A piece oi' paper havingainixture ot coloring matter and grease rubbed over it will answer. r1`his pad or paper is secured by springs if, to the under side ofthe lid t) ot' thccase. The impression is given by the parts ot the type. pressing' the paper in contacty with the pad N. 'lhe keys 0r. linger-pieces Il may ,bc readily oymrated, either singly or two ormoreat aV time, so as to form the several letters. The lines, it will .be seen, are printed on the paper in curved form, owing to the curved path the lplate B describes in its upward n'iovement, and at the termination ot' each line the plate 'l5 drops, owing to the throwing` out of the holdingpawl, and thc paper c is moved. a. triiie upon the cylinder b at the first upward movement ot' the plate B, so as to cause a proper space between the lines. This movement of the paper c is eii'ected as follows: As the lever D is pressed` inward at its first movement in commencing.,r a. line, the. end a. otl its longest arm comes in contact with a 'sliding pawl, l,

which engages with a ratchet, b', on one end" of the cylinder b. 'liiis pawl l is at the lower side of the case. A, and connected thereto by a swinging plate, ai', and it, is provided at its frontend with a barb, c', which catches over aprojection, d', ou a pawl, which works on a pivot, e', and which lalso eng-ages with the ratchet b'.

'R is a spring', which bears or acts 'against both pawls l? Q, and has a tendency to keep both paw'ls engage with the. ratchctb when theA pawl l is shoved forward, and also to throw the pawl l back from the ratchet. The pawl Q is a holding,` one, and prevents the cylinder b f'om casually turning while the pawl P is thrown back 'by the sprinf. By pressing down the back end of the pawl Q, both pawls will be disengaged from the ratchet b' and thc paper c adjusted as desired.

l would remark thatnumerals may be formed by the combined type I, the several parts being used singlyand Icoi'nbiue-d so as to approximate as nearly as possible to the known form of the same.

Raving thus described my invention, what I`claim as new, and'desire lto secure by Let ters Patent, is-

1. The combination-type I, formed ot' a. se-

-of the type.

3. The plate '3rackbar C, and lever D, the latter being provided with the pawls E F,

' provided, respectively, with prongs 'or arms h' fi', for the purpose of feeding 'or moving the type across the paper, as set forth.

4. Counecring the arms K with the leverD '0, as set forth.

of plate E through the medium of the bar or arm J, lfor the purpose of moving the type across the paper simultaneously with the giving of the impression, or just; before the im.

pression is given, as set forth.

5. The two pawls P Q, arranged, as shown, in connection with the ratchet b and the leverD o f the plate B, -for moving the paper B EN J AMIN LIVE RMORE.
