PATENT FFICE ALBERT B. DICK, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE A. B. DICK COMPANY, OF SAME PLACE. I
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 545,403, dated August 27, 1895.
Application filed August 30, 1893.
To all whom it may concern;
Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Type -Vtriting Machines, of which the following is a specification.
The object of my invention is to secure a type-writing machine of low cost which shall be capable of doing work as good, or nearly so, as any of the type-writing machines now on the market, and which shall be capable of manifolding and be especially adaptable for operation in connection with the production of stencils by the well-known mimeograph process of producing type-writer stencils.
My invention consists in the devices and combinations of devices,hereinafter described and claimed.
In the-accompanying drawings, forming a part of this specification, Figure l is a front elevation with certain of the parts broken away to better reveal details. Fig. 2 isaplan view thereof with the platen and connected mechanism removed. Fig, 3 is a plan view of the frame of the machine. Fig. 4 isa side elevation thereof, partly in section. Fig. 5 is a plan view of the platen-holdin g frame. Fig. 6 is a sectional elevation through the typewheel with some of the operating parts therefor. Fig. 7 is a detail of the paper-shelf and platen. Fig. 8 is a plan view of the typewheel, gear, and sector. Fig. 9 is a detail of the lever. movement for operating the feedpawl, alignment-tooth, and hammer. Fig. 10 is a detail side view of the carriagefeed pawl and rack.
The frame of the machtne is secured on any suitable table A, and comprises a base B, from which rise at the rear end thereof a vertical plate 0, and from near the front thereof, atthe sides, two posts D. The rear plate C is cast with split sleeves E for receiving the rack-rod of the carriage-feed, and has projecting from it toward the front of the machine two extensions F G, in the upper of which extensions atf is stepped the spindle for the type-wheel, and between which extensions, at points f 9, passes the spindle carrying the mechanism for rotating the type- Serial No. 484,355. (lilo model.)
wheel. Two lugs H also extend from the back plate of the machine, and these logs serve to receive the pivot for the lever movement operating the feed. A post H for the bell also projects from said back plate. At each side of the plate F extend two shouldersl I, which receive a plate in which the upper end of the type-spindle has its bearing and on which also swings the bell-hammer. The posts D D are connected by a plate J, which plate has upward projections K K for receiving the rock-shaft, hereinafter to be described, and outward and downward projections L L, which receives another rock-shaft for operating the hammer. Still other upward projections M M receive the front scale, and another downward and outward projection N receives the movable piece, which is struck by the hammer and operates the type; also, rising from the front plate are two short posts 0 0, connected by a raised rib P. Upon said short posts is supported the operating-board of the machine with an index-lever having a hearing upon the said rib P.
- It is to be understood that the parts of the frame just described can be of cast metal, and that by this construction simplicityand economy in manufacture are attained.
The operative parts of the machine may be best described by describing separately the type-wheel, the feed mechanism, the operating-board and index, and the printing mechanism.
The type-wheel is preferably constructed of two separate plates of metal 1 2, the upper and lower plates both being provided with a series of teeth 3, forming slots for the reception of the loose type 4, which type are shouldered, as shown, so as to prevent dropping through the said slots, and provided with a stem or spindle X, which projects below the lower edge of the lower plate 2. Said plates are connected together by a band 5, of metal or other suitable material, which passes into a groove on the lower side of the upper plate 1 and a corresponding groove on the upper side of the lower plate 2. By this construe tion it will be seen that the type wheel is adapted to receive any kind of type, and that the type can be readily inserted in place and ICO as readily removed, either for the purpose of changing the font or to replace worn-out characters.
The operating-board and index comprise a slotted sector-shaped piece 6 and an operating-lever 7. Said slotted sector is supported from the frame of the machine, and has arranged on it in any desired order the letters and characters corresponding to the type on the type-wheel and arranged in the same order. The index-lever at its rear end is rigidly secured to the spindle of the toothed sector 8, which of course turns with the movement of the lever and operates the gear 9 on the spindle of the type-wheel, whereby movement is communicated to the type-wheel in any desired direction. Of course it will be understood that the number of teeth on the gear and sector, respectively, are so calculated with respect to the number of type on the type-wheel that for a given movement of the index-lever a number of characters on the typewvheel will move past the printing-point in correspondence with the number of characters on the operatingboard, past which the index-lever has moved. The index-lever passes underneath the operating-board 6 and has three projections 10, 11, and 12, the center one of which 11 enters into the arc-shaped slot in the operating-board and the other two of which are adjacent to the outer edges of the said board, as shown. These projections are provided with index-lines and with a term designating the character of printing effected. by their operation-as, for instance, the middle projection may contain the word Caps, while the other two projections contain, respectively, Figures, Characters, and Small. This index-lever is preferably provided with a pivoted handle 13, which permits the free and easy operation of said index-lever.
The platen 14 is carried in the frame 15, which is preferably of cast metal, which frame is carried by the rack-rod 16, whichin turn is supported in the split sleeves E E. The platen-may be of the usual construction found in standard machines, such as the Remington and Caligraph, and is provided at one end with a ratchet-wheel 17, controlled by a pawl 18, pivoted in said frame 15. A milled wheel 19 is also provided to facilitate the turning of the platen by hand for linespacing. The paper-shelf 20 of the carriage is of the usualgconstruction and extends for nearly the full length of the platen and is pivoted at each end in the side of the frame 15, as shown at 21, Figs. 5 and 7. At each end of the spindle 21 a spring 22, one end of which is coiled around the spindle 21 and the other end of which is fastened to the side of the paper-shelf, exerts pressure on the lower end of the paper-shelf, so as to throw that end against the platen. A roller 22 is carried at this end byithe paper-shelf, and hence an even pressure is exerted upon the paper in the machine, and the same is kept from slipping, while at the same time it may be easily removed by'pressing the upper end of the paper-shelf toward the platen.
The cylinder-scale 23 is held in position by the metal strips 24 25, the front end of which is secured to the front of the frame 15, as shown in Fig.1, and the rear end of which rests, as shown in Figs. 5 and 7,on the spindle 21 of the paper-shelf. The envelope-holder is formed from astrip 26,bent partially around the cylinder, the front end of which is secured to the frame 15, and which is tapered to a point and runs along on the upper edge of the front scale 30.
27 is an indicator, which projects downwardly over the front scale 30.
28 29 are sheaves journaled to the frame 15 and supporting the front of the carriage upon the upper edge of said scale.
The feed mechanism is operated from the plate 31, pivoted on the base B at one side of the machine. This pivoted plate is connected by a series of straight and elbow levers 32, 33, 34, 35, 36, and 37 to the feed-dog 38, said feed-dog engaging with the teeth on the rack 16. It will be obvious that by a downward movement of the plate 81 the system of levers connected therewith will be so operated as to withdraw the dog from one tooth and insert it in the next, and through the action of the spring 39, one end of which is connected with the elbow-lever 35 and the other end with the frame of the machine, the rack and connected mechanism will be fed forward one tooth, the dog being held up to the rack by the spring 38*.
The printing movement is effected through a plate 40, which is pivoted at 41 on the post D at the same side of the machine as is pivoted the feed-operating plate. Attached to the rear end of the said platform is a lever 42, which is connected with the crank 43 of a rock-shaft 44, which rock-shaft at one end carries the hammer 45. It will be obvious that by pressing the plate 40 the crankarm 44 will be moved and the hammer 45, which is rigidly connected therewith, will swing. In the path of the hammer is a movable anvil 46, in the form of a plate of metal, r
with two pins or extensions 47 47, which prevent it from dropping through the slot in the projecting end of the main frame. The movable anvil is directly beneath the printing position of the type, and is in line therewith, so that when it is struck by the swing ing hammer it will be projected upward against the bottom surface of the type, and hence will force the type from their pockets or sockets against the paper, and thus effect the printing. By causing the hammer to contact with the anvil instead of directly with the ends of the type I am able to use a hammer of any suitable shape. The anvil is of such width that it will contact with butone of the type at a time, whereas if the hammer struck directly against the type more than one of them might be impelled upwardly against the platen.
lIO
The alignment of the machine is secured by providing a finger 48 on a rock-shaft 4.9, which is shown as secured to said rock-shaft by a sleeve 'and set-screw 50. Said rockshaft is operated from the platform 40 through lever 42 and link 51, which connects the rocker-arm 52 with the rocker-arm 44, whereby, by the movement of the platform 40 for the purpose of eifecting the printing, the finger 48 will be moved into the teeth of the lower plate 2 of the type-wheel, and as the spaces between these teeth correspond to the type it is obvious that the wheel will be locked in the printing position during the moment of printing and that the finger entering from beneath can enter between said teeth and thus efiect true registration.
The ink-ribbon 59 is wound upon two spools 54 55-one on each post Dof the machine. The spool 55 is provided with a winding-arm 56, and the other spool 54 is provided with ratchet-teeth 57, with which engages a pivoted pawl 58, resting upon a spring 58*, (shown partly in dotted lines in Fig. 2, said spring being for the main part beneath the platform 40,) whereby each movement of the platform to effect a printing operation effects a partial rotation of the spool, and hence a feed of the ribbon. A dog 60 prevents a backward movement of the spool, while two guide-plates 61 61, supported on the posts K K, one being located on each side of the type-wheel, guide and steady the ribbon. As shown, a projection 60 from the dog 60 rests upon the pawl 58, said pawl being provided with a finger-piece 58", whereby when the pawl is moved out of engagement with the ratchet-teeth the dog will be simultaneously moved out of engagement, thus by one movement freeing the spool, so that winding may begin. By providing a lip 62 on the plate 31, which lip enters beneath the bottom of the plate 40, I am enabled by the downward movement of said plate 40 to also move the plate 31, and hence during the printing operation I am enabled also by the same stroke to effect the carriage-feed, although I may, when desired, feed the carriage separately simply by operating 31 alone.
The bell 63 is suitably supported from a post cast on the back plate of the frame, and its hammer 64. is suspended from a plate 65, in which is supported the upper end of the spindle of the type-wheel. The bell-ringer 66 is adj ustably secured on the rack-rod 16 by a set-screw 67. From the plate extendsa light spring 68, which bears on two or three of the type at the printing-point, so as to return them and prevent them from jumping out at other points, the balance of the shieldplate 65, which extends over the rear extension of the type, preventing the same from being jarred out of the slots.
The operation of the machine will readily be understood from the foregoing description, it being necessary only to remark that the loose type are projected upward against a platen above the same,whereby an action analogous to the action of a standard machine, such as the Remington, is obtained-that is to say, by this arrangement a swinging platen may be used which can be handled in the same manner as is the platen on any ordinary machine. It will also be understood that I am not limited to the precise details of the mechanism for operating the parts shown by me, and especially may the anvil be dispensed with, the hammer being so arranged as to strike the type or a projection therefrom directly.
