IMPROVEMENT IN TYPE-WRITING MACHINES.

Specification forming part of Letters Patent No. 206,160, dated July 23, 1878 ,1 application filed April16, 1677.

To all whom it may concern:

Be it known that I, BENJAMIN Fnamnv BELLOWS, of Weeping Water, county of Cass, and State of Nebraska, have invented certain new and useful Improvements in Type-Writers, of which the following is a specification:

Reference is had to the accompanying drawings, which are madea part hereof, and on which similar letters and figures indicate simi lar parts. I

The object of my invention is to provide an efiicient means of writing with type or printing a singlecopy in cases where it has been usual to produce the writing desired with a pen.

This is accomplished by a machine constructed for the purpose, and which is generally known as a type-writer.

Figure l is a front view of my invention.

Fig. 2 is a perspective view of one of the keys.

Fig. 3 is a view of attachment ]3 for holding cards. Fig. 4 is a side view of the type and the type-holder M... Fig. .5 is a sectional plan drawn for the most part through the dotted line 0 0, but varied from said line inplaees in orderto illustrate'as much as possible of the invention when looking into the machine from the right-hand side. Fig. 6 is a front plan of spacing contrivance G. vFig. 7 is a view of the inside of the front part of the machine when viewed from a point corresponding with the dotted line 0 c inFig. 5. Fig. Sis a view of the parts immediately in the rear of those.

shown in Fig. 7, as shown when looking rearwardly from the same dotted line e c. This line is varied from at the top of the figure, in

order to get a front view of the type-holder M. Fig. 9 is a view of propelling and holding catch E, and the various levers and attachments near to or connected with it when looked at from a point shown by thedotted line f f. This figure also gives a view of key 30 and the levers attached thereto. Fig. 10 is a view of key 30 with its connections, and of the spacing contrivance G.

In the drawings, the numerals l to 30, inclusive, represent the keys, which are arranged to work as follows:

1, if struck alone, causes the hammer to strike on the small or lower-case letter a, and

thus makes that impression on the paper. If

struck in combination with 6, and whilefi is yet down, its operation 'is changed to the capital letter A, while in combination with 5 the numeral .9 is formed. 2 in the same manner, alone makes b; with 6, B; with 5, 3 alone makes 0; with 6, G; with 5, 4 alone makes d,- with 6, D; with 5,, 7; 5, when used in connection with the working keys, makes the numerals and various stops and marks. 6,

when used in connection with the workingkeys, changes the letters from lower-case to cagital letters.

he operation of these two keys 5 and 6 is hereinafter more particularly described.

Keys 7,8 9,10, 12,13, 14,15,16,"17, 18,19, 20, 21, 22, 23, 24, 25, 26, 27, 2s, and 29 operate in a similar manner to keys 1, 2, 3, and.4, and complete the entire list of 'seventy-eight characters now used with this machine, including letters, both, lower case 11nd capital, and the stops and numerals.

Key 11 is used in combination with the elbow-lever H, having thebeveled head It on its upright portion to raise the bed-plate I, which,

in turn, raises the paper-holding apparatus a sufficient distance so that the dash-mark can be used as an underscoring attachment.

Key 30, through the levers p and 4, moves the spacer G so as to engage it with the gearwheel 0 on theend of roller 0 and which, in

turn, engages with gea -wl1'eei 'c on end of roller 0, and thus turns said rollers while they are being run back, so asto give the necessary space between the lines of writing on the pa per. This space can be made wide or narrow at pleasure by setting the incline a; at a greater or less angle. The incline a is held in its place by the set-screw d, which runs through the slot in the carrier-bar b.

The type are closely arranged in the typeholder M, so that the hammer A can reach each one without danger of missing by reason of a too great movement of the type-holder M.

The handle of the hammer A is provided with a screw-thread, on which runs the weight D. This weight enables the operator to give a lighter or heavier stroke on the type at will by simply running the weightfarther from or nearer to the point of the hammer, the hammei, of course, striking heaviest when the weight is nearest the point.

' oted to the plate V, and

The type are arranged in three perpendicular sections of three rows each. The righthand section is capitals, the central section is small or lower-case letters, and the left-hand section is the stops, marks, and numerals.

If the working-keys alone are used, the central or lower-case section is under the operation of the hammer. If thecapitals are wanted, in addition to the working-keys, use operatingkey 6. It stops, marks, or numerals are wanted, use in connection with the working-keys the operating-key 5.

Key 5 pulls down lever K, which is jointed to plate L, which is, in turn, jointed to the front part of the machine. The plate L has an inclined slot, which runs over pin m in plate W, and which draws said plate \V, wit-h its companion-plate V, to the right, and with them the type-holder M, whereby the left section of type is brought under the operation of the hammer A.

Key 6 pnllsdown the lever N, which is jointed to the plate 0, which is, in turn, jointed to the front part of the machine. The plate 0 has an inclined slot, which runs over the pin a in plate \V, and which draws plates \V and V to the left, whereby the right section of type is brought under the operation of the hammer'A.

The plate V has a projection, V, to which the type-holder M is connected by means of the connecting-rod M, and by means of which the type-holder is made to follow the motion of the plates. The type are also arranged in nine horizontal rows, and each row is raised to position to be struck by the arrangement of levers shown in Fig. 8.

The pivot k on the bottom of the stem of the type-holder rests in the slot J. When the pivot k is at the bottom of the slot, the first or top row of type is in position to be struck, and the keys for this row do not pass through the loops of any of the levers; but when the second row is to be struck the keys run through the loop of lever S, then the third through the loop of S, and so on, the lever S raising the type-carrier, until the bottom or ninth row of type is in position for use.

Inside the front part of the machine are arran god the three slides 1, Q, and B, through which the stems of the keys run, and which, when struck by the keys, draw down the pin i in hammer-shaft j, and thus strike the hammer A against the rear end of the proper type. They also, by means of various connect-ions, shift the type-holder M a single space, so that the right and left hand rows of the sections may be used.

The slide P is not connected with either of the plates, and, consequently, when keys are struck which rest on this slide alone the plates are not moved, and the hammer A strikes the central row of whichever one of the perpendicular sections is being used.

The slide Q is connected with the plate T by means of the lever Q. The plate T is pivhas an inclined slot,

,the parts fastened thereto which runs over pin a in plate W,whereby the plate V, which carries the type-holder M, is carried one space to the left, and the righthand row of any section is brought under the operation of the hammer A.

The slide R is connected to the plate U by the lever B. The plate U is pivoted to the plate V, and has an inclined slot, which runs over the pin m in plate W, whereby the plate V and type-holder M are carried one space to the right, and the left-hand row of any section of type is brought into use.

Immediately in the rear of the levers S to S is the propelling and holding catch E. This catch is composed of the upright standard '1' and pivoted jaw s, and is driven by means of the lever 1. Shown in Fig. 9.) This key fits closely into t to small slot 0, (shown in Fig. ,7,) and thereby closely follows every movement of the slide 1?, and as the slide I is worked by every o'ne of the working keys the standard r is, of course, pulled downward by each stroke on any of them. Whenever the catch is pulled down and disengaged, the jaw s flies upward and backward, and engages atooth in the rack-bar to the right. of the one disengaged, and, as the catch rises, the jaw 8 comes forward and downward, and pushes the rack-bar F a space farther to the left, thus giving room for another letter on the paper. The stationary jaw on the upper end of the standard 1' engages the opposite side of the tooth which is being pressed against by the jaw s, and thus holds the rack-bar and all of firmly in position while the type is making its stroke.

The paper-holding attachment is composed of the three rolls 0, C, and C, which are held in place by the arrangement of levers and springs shown in Fig. 5, and is propelled in the proper direction and to proper distances by the action of the spacer ti and catch 1' described above.

The roll 0 is held in place by the pivoted lever o, and the roll 0 by the pivoted lever :1.

0n the rod 3 is the spring 2, which is fastened at the other end to the bed-piece I. This spring z presses the roll 0 downward, and with it the roll 0, as the roll 0 is on top; otherwise a second spring would be needed.

The levers 0 and t and the spring :2 are duplicated at the opposite ends of the rolls, and are connected together by the. rods w and y.

The paper-holding attachment runs on a slide or carriage composed of the rod X and partly-open tube Z, so arranged that it will slide from either end of the machine without difficulty, and can be replaced at pleasure.

The main roll 0 has an attachment, B, for

holding postal or other cards, or pieces of paper too small to, reach under the smaller rolls. It consists of two flat pieces hinged together, and the inner end is pressc upon the roll 0 by means of a spring in the outer end,

In Fig. 9 is shown the lever Y. This lever has a projection, 11,

in standard 1', and is pivoted 'to the lever q,

which engages the pin 1" so that when the key 30 is pulled down it also pulls down the catch E, and thereby relieves the rack-bar 1* from all. interference while being run back. I

The operation of my machine is to speedily and easily write any matter that may be desired, in either lowerease or capital letters, with all numerals and necessary stops and marks. One of its most marked advantages is that it makes nearly twice the number of char-, actors that have been made by machines heretofore invented with a much less number of keys. I use only twenty-six working and four operating keys, making thirty in all, and make seventy-eight character's, while others have generally used over forty keys, each capable .of making only a single character.

I disclaim, however, all that part of this invention which relates to the combination of the combined hinge and guide-rail with the paper-carriage, by which said carriage is enabled to be moved along and over the machine and up and'ofi' from the same. I also disclaim the combination of a ratchetrbar with such a device, and also the combination of a hinge and guide-rail on one sideand a travelingwheel on the other with such a carriage; but,

' Having thus fully described my said invention, what I do claim as new, and desire to secure by Letters Patent, is-
