SPECIFICATION forming part of Letters Patent NO. 543,164,'dated July 23, 1895. Application filed April 26,1853}. Serial No. 509,060. (No model.)

To all whom it may concern:

Be it knownthat I, CARL W. WEISS, of Brooklyn, inthe county of Kings and State of New York, have invented certain new and useful Improvements in Type-\Vriters; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, making a part of this specification.

This invention relates in general to that class of type-writing machines in which the 'type characters are supported by a carrier which is rotated or oscillated or vibrated to bring one or another of such type characters to the line of printgbut as the description of the preferred embodiment of the invention proceeds it will be seen that various features of the invention are applicable to other forms of machines.

The object of the invention is to produce a type-writing machine of low cost of manufacture, of easy and rapid action, and of great durability and efficiency. The bringing of the type characters to the line of print is controlled by pneumatic devices whereby the use of levers intermediate the keys and the type characters or type-carrier is dispensed with and the action of the machine made correspondingly lighter, and the construction simpler, cheaper, and less likely to be disarranged. The type characters are mounted upon a suitable carrier, and instead of requiring the paper to be brought against the type (with an interposed ink-ribbon) as is usual. in machines of this general character, the type characters are adapted to be moved individually against the paper.

In the particular machine for illustration of the several features of the invention the type characters are secured to light springs which are mounted abouta hub. The latter is impelled to rotate by a clock-spring or other suitable motor acting through simple gearing and the keys of the machine are adapted to operate corresponding plungers, which release the type-carrier for movement and determine the extent of such movement. It will be understood, however, that the several mechanical devices and their combination and arrangement may be varied without departing from the spirit of the invention.

In the accompanying drawings, Figure 1 is a front view of a type-writing machine which embodies the invention. Fig. 2is asection on the irregular plane-indicated by the line a; m of Fig. 1. Fig. 3 is a detail section through the keyboard. Fig. 4 is a partial section on the liney y of Fig.2, looking in the direction of the arrow. Fig. 5 is a plan view of the'es- .capement-plate, showing also the friction-dog with the driven shaft in section. Fig. 6 is a detail perspective view of the friction-dog shown in Fig. ,5. Fig. 7 is a detail view show ing the upper faceof the main gear with its hammer-actuating cams, the stem of the hammer-lever and the driven pinion and its shaft being shown in section. Fig. 8 is a detail I view ofthe under side of the same gear, showing the spacing-clutch or escapement. Fig.

.is a detail view of one of the spring type-bars removed from the carrier, also on the same scale as Fig. 9.

In the machine represented in the drawings the various working parts are supported bya frame or casing; 10, which may be of any desirable form, but is preferably so constructed and arranged as to support in an inclined position the front plate 11. A second plate 12 is held parallel with the front plate 11 by studs 13, and by these two plates most of the working parts are directly supported.

In a suitable bearing carried by the plate 11 is journaled a short shaft 14, which is impelled to rotate in one direction by any suitable motor, such as a clock-spring 15, and to which is connected 2. largegear 1b. The latter engages a pinion 17, mounted on and adapted to drive a shaft 18 to which the typecarrier is connected, the ratio of the gear and pinion being preferably as ten to one, where- 5 by the pinion receives a complete rotationfor every one-tenth of a rotation of the gear.

is substantially of ordinary construction, having a roller 22, mounted in suitable bearings 23, and a presser-roll 24, and being adaptedto slide to and fro in guides (preferably three in number) which are secured to the plate 11.

It 'is obvious that as the pinion 19 rotates under the influence of the spring 15 the carriage will be moved in the proper direction for printing the successive letters and words of a line, and that when the carriage is moved in the opposite direction by the hand of the operator the spring will be rewound. The pinion 17, of course, does not rotate continually, but its rotation is controlled by an escapement device which permits only a single rotation-of the pinion for each operation of the escapement. A block 27 is held frictionally upon the shaft 18 by spring-clamps 28 (see Figs. 2, 5, and 6) and has an aperture 29 parallel with the axis of the shaft, which is engaged by a pin 30 fixed to the hub of the pinion 17, the latter being mounted loosely on the shaft 18, and having a sleeve 31 with a flange 32 for engagement with a roller 33 carried by a bracket 34 fixed to the plate 11, whereby the pinion is permitted to rotate independently of the shaft under certain circumstances and is held from longitudinal movement thereon. The block 27 also is provided with a fingerw35 which is adapted to be engaged by a stop-pin 36 fixed to a swinging plate 37. The latter is hung upon suitable brackets 38 secured to the upper portion of the plate 11, and is arranged to be moved very easily. A guard-pin 39 is also fixed to the plate 37 to insure the proper action of the escapement device.

From the foregoing it will be understood that at each operation of the eseapement device the pinion 17 makes a complete rotation while the shaft 18, being carried frictionally with the pinion 17, may also make a complete rotation or may be stopped at any point in such rotation.

The means whereby "the rotation of the shaft 18 is checked at any point which may be necessary to bring the type-carrier to rest with the desired type character thereon at the line of print will presently be described. Such means comprise, in the machine represented in the drawings, a series of movable stops which are arranged in a circle about the axis of the shaft 18 and are adapted to be moved, at the election of the operator, to strike the plate 37 for the purpose of releasing the-escapement, and also to stand in the path of an arm 40 which is carried by theshaft 18, whereby the rotation of the shaft will-be checked at a point determined by the particular stop which is operated.

As represented in Figs. 2 and 4, the arm 40 is forked to embrace the shaft 18 and is held thereto by a pin 41 which passes through the shaft, whereby the arm is free to swing more or less in a plane passing through the axis of the shaft.

As hereinbefore stated, the movements of the type-carrier are controlled by pneumatic devices, whereby the usual finger-keys and the several type bearers or levers are dispensed with. Accordingly the movable stops before referred to are formed as pistons 42, which are arranged to move through cylinders 43, secured to the plate 12. Each cylinder is connected by a suitable tube 44 to its respective air-compressor, which constitutes the finger-key. As represented in the drawings, each tube 44 is connected to a corresponding nipple 45, which is secured to the under side of the plate 11, while a small rubber bulb 46 is secured upon the outer side of the plate 11 over the orifice through each nipple 45. As shown clearly in Figs. 1 and .3, all of the air-compressing bulbs or finger-keys 46 may be conveniently secured in place by a single plate 47, which has apertures for the several bulbs and is adapted to be screwed down to clamp the flanges of the bulbs firmly to the plate 11. Whenever any one of the bulbs 46 is struck by the finger of the operator the air, or whatever other fluid may be employed, is compressed sufficiently to drive out the corresponding plunger 42, and to cause it to strike the plate 37, thereby releasing the escapement and permitting the pinion 17 and shaft 18 to rotate together. The pinion will complete its rotation at every operation, being stopped only by the contact of the finger 35 with the stop-pin 36 at the end of its revolution. The shaft 18, however, will be checked by the contact of the arm 40 with the particular plunger which has been thrown out, the plate 37 being set at some distance from the plate 12, so that the plunger thrown out, whatever may be its position in the circle with reference to the former position of the arm 40, shall not have time to fall back out of the path of'the arm before it is struck by the same. The elasticity of the fluid medium employed, together with the elasticity of the the containers, will be sufficient to allow the plunger to be held out by the contact of the arm 40 therewith until the printing operation has been completed, or at least until the pinion 17 has been brought to rest by the escapement device.

It will be'seen that whenever one of the plungers 42 is thrown out the type-carrier will be moved, and, as willappear more clearly hereinafter, the printing-hammer will also be actuated. f

It further becomes necessary, or at least desirab1e,'to provide independent means for permitting movement of the paper-carriage independently of the mechanism just referred to for the purpose of spacing. Accordingly the gear 16 is not fixed to the shaft 14, but is connected thereto through a clutch or escapement device which can be operated by the spacing-key to permit a movement of the shaft 14 sufficient to advance the paper-carriage one space. The gear 16 is mounted loosely upon the shaft 14 and bears upon its IOC shapedin order to combine rigidity with lightness. Between one end of. the escapementbar 51 and its support is fixed a light spring 52,- which is sufficient to keep the longer arm 'of the bar normally away from the gear 16 and beyond the path of the cam-lugs 48, while the other end of the bar rests against the vertical face of one of the cam-lugs. In line with the shaft 14 a piston 53 moves in a cylinder 54,

which is secured to the plate 12 and is connected by a tube 55 with the spacing key or compressor indicated at 46 in Fig. 1. The operation of the spacing-key causes the piston 53 to be thrown up to strike the escapemeutbar 51 with su'lficient force to disengage its shorter arm from the lug 48 with which it was in engagement, and accordingly to release the shaft 14 from the gear 16, which is held from rotation by the escapelnent devices 35 36, as

concerns the mechanism already described the type-carrier might be of any usual form and arrangement, and that the paper might be moved against the type to produce the impression by a hammer, or that the impression might be produced in any other usual and The particular form of.

well-known way. type-carrier which I prefer to employ, how

ever, is that shown in Figs. 1 and 2, andon a larger scale and in detail in Figs. 9, 10, and This type-carrier comprises a hub or sleeve 56, having at one end a disk 57 with stepped notches 58 about its circumference and a flange 59 outside of the notches 58,and

a second disk 60 with a series of radial notches 61 near'the circumference thereof and corresponding to the notches 58.

The type characters (indicated at 62 in Fig. 9), are formed upon or secured to narrow strips of spring metal 63, each strip bearing in a longitudinal seriesa lower-case letter, an upper-case letter, and a numeral or punctuationmark, or other desired character. The other extremity of the strip is notched, as at 64, and is provided near the notch with a head or rib. 65. In assembling the parts of the type-carrier each strip 63 is slipped through the proper slot 61 and into the stepped notch 58 corresponding therewith, the head or rib 65 hearing upon the inner sideof the flange 59 and forcing the notched portion of the'strip into engagement with the narrow'portion of the notch 58. The strips will then rest normally against the inner ends of the slots 61 in the upper disk 60, and may be moved from within outwardly toward the paper by a suitable hammer which moves within the circle of strips. The type-carrier stands normally in such position as to bring the lower-case letters opposite the line of print, and in order that the upper-case letters or the numerals and punctuation-marks may bebrought to the line of print the carrier is made to move 1ongitudinally with "the shaft 18 as well as to turn therewith. For this purpose a sleeve 66 is fixed to the shaft 18 by a pin 67. At the outer end of the'sleeve 66 is an arm or preferably a disk 68, to which is fixed a pin 69 which passes through a hole in the disk 57 of the type-carrier. The sleeve 66 rotates always with the shaft 18 and moves longitudinally therewith and is therefore adapted to lift the type-carrier or to move'the same outwardly. The type-carrier might be fixed to the shaft '18; but in order to permit of its re:

block 18 which is carried by the shaft 18,

provision being made topermit of rotation of the block and shaft with respect to thelink 72.

The means for producing an imprint, after the type-carrier has been set, comprise a hammer and devices for actuating the same after the typeearrier has come to rest. The hammer proper 73 is bent substantially as repre-- sented in Fig. 2 and is pivotaily mounted upon the outer end of a hammer-lever 74, pivoted on the front plate 11, the hammer having a lug 73? which rests upon a stop-pin 74 fixed to the lever 74, whereby the hammer is carried toward the paper by the movement of the hammer-lever, but may be turned back .out of'the way whenever the type-carrier is to arranged that they will successively lift the end. of the hammer-lever against the pressure of a spring 76, which'is arranged to bear upon IIO said lever and to allow it to slip off just as the gear and pinion come to rest, thereby causing the hammer-head to be moved sharply against the inside of the particular letterstrip which may be in line with it, and to cause the same to strike the paper or the interposed ribbon. The spring 76 is held in place by a thumb-screw 77 and nut 78, whereby the pressure of said spring upon the hammer-lever may be adjusted to regulate the force of the blow of the hammer as required.

In order thatthe machine may be represented in a complete form, the drawings show in Figs. 1 and 2 an ink-ribbon 79, which is carried by

spools

80 and 81 mounted upon

standards

82 and 83, and is guided between the type-carrier and the paper-roller 22 by a suitable plate 84.

It is obvious that the'features of the invention might be embodiedeither severally or conjointly in other arrangements than the particular one shown and it is to be understood accordingly that the structure herein shown and described is not essential to the application of the invention, but is merely one embodiment thereof.
