TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 504,897, dated September 12, 1893.

Application filed December 3, 1892. Serial No. 453,957. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE B. WEBB, a cit-izen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writ ing Machines, of which the following is a specification.

My invention relates more particularly to carriage raising and releasing means and to that class of devices for performing column or tabulated work made the subject of an appllcation filed by me December 2, 1891, Serial No. 413,756, and consists in the various features of construction and combinations of devlces hereinafter more fully described and particularly pointed out in the appended claims. I

In the accompanying drawings, Figure 1 is a plan view of the paper-carriage of a Remington type writing machine, (stripped of its platen, platen-carrier, paper-feeding mechanism, &c.,) the guide and hinge rail, and the usual shift-rail for the platen frame or carrier, and showing also my present improvements. Fig. 2 is an elevation of the same taken at the left hand end of the machine with the top-plate added. Fig. 3 is a front elevation of the same. Fig. 4 is a vertical cross-section taken at the line a: a; of Fig. 1. Fig. 5 is a rear, detail elevation, or a view looking in the direction of the arrow at Fig. 4, and Fig. 6 is a rear elevation, showing a pivoted dog.

In the several views the same parts will be found designated by the same numerals of reference.

1 designates the posts or pillars, and 2 the top-plate of a Remington machine.

3 is the main carriage hinged by eyes 4 upon the guide-rail 5, and provided with grooved wheels 6, which run uponsaid rail. A frame 7 is also hinged to swing about said rail, and is provided with afeed-rack 8, which oo-operates as usual with the letter-spacing dog 9. Attached to said hinged frame 7is an arm 10, which is bent to pass over the rail 5 and extended forward to terminate contiguous to the rear end of the left hand side bar of the carriage. In bearings 11 on the outer Side of said side bar is mounted a rock-shaft 12, which at its rear end is bent inwardly under the said side bar, and rests at its free end upon the forwardly extending arm 10. At the free end of the rock-shaft is secured a fingerpiece or key 13, which projects upwardly and inwardly over the said side bar of the carrlage.

On the front bar of the carriage at the left hand side is fastened, by screws 14, a bracket 15, which at each end is provided with a forwardly-extending eye or bearing 16. The bracket between said eyes or bearings is cutaway or open and between the ends of said bracket immediately over the front rail a space or opening 17 is left for the passage of the rear arm 18 of a lever 19, a portion of the front arm 20 of said lever fitting in the space formed between the eyes or bearings 16, the remainder of the forward arm of said lever 19 being formed or provided with a handle 21. The said lever 19 is attached, by a screw 22 to a bar 23, which is seated or fulcrumed in the eyes or bearings 16 at one end, (thus forming a pivot for the lever,) and which at its opposite end is bent at right angles and rearwardly to extend over and lie adjacent to the finger-key 13.

Attached to or formed integral with the arm 18 is a depending lug or stop 24, and attached to the bracket 15, by one of the screws 14., is a spring 25, which is bent to bear upon the top of the arm 18 and hold the lever 19 down against the upper side of the front bar of the carriage, as shown clearly at Fig. 4.

Mounted upon the top-plate 2, or some other stationary part of the machine, and preferably by detachable brackets 26,-is a rod 27, arranged parallel with the pivot of the lever 19, and having aseries of perforations 28 into which may be fitted one or more stops or pins 29. The perforations or holes 28 are arranged apart or graduated to correspond with the divisions of the machine scale 30. Preferably, however, there is only one hole to every five figures of the scale, as this arrangement has been found in practice to be ample. The

holes are preferably numbered as shown to aid in facilitating the work.

At Fig. 3 of the drawings, two pins or stops 29 are shown, one at the hole 20, and the other at the hole 40 of the said rod 27. The

' arrived at 30 on the machine scale.

lower end of the projection, lug, or dog 24 stands in aplane in front of the line of holes or pins in the normal position of the arm or lever 19, so that in doing ordinary work the dog 24 may pass freely by the said stops or pins. By depressing the said arm or lever 19 at its handle-end 21 the dog may, however, engage with said pins upon arriving thereat, and by such engagement or contact arrest the carriage. The pointer 31 attached at the axis of the front supporting roller 32 of the carriage shows at Fig. 3 that the carriage has If it be desired now to have the carriage moved quickly to the point 40 on the scale (so that a column of figures may be commenced, for example) the dog 24 is swung rearwardly bybe'aring down upon the handle portion of thelever 19. By this movement the bar 23 isrocked in its bearings, and itsrea-rwardlyprojecting portion caused to rise and bear upon or against the finger-piece-of the rock shaft and operate to turn said rock-shaftand causeitsinner portion to depress the arm 10 of the hinged frame, and lift the rack-bar 8 from engagement with the spacing-dog. As soon as this is accomplished, a spring-drum or power 33, (which may be of any known or suitable construction) actsto propel or pull the carriage rapidly toward the left until the dogi24 strikesor abuts against the stop or pin 29 at the hole 40. The pressure upon the handle 21 may be then released and the lever contrivance 19 will be returned to its normal positionby the spring 25. After'the carriage has been arrested, and the dog permitted to return w its normal position, the writing may bepro'ceeded with to the full limit of travel of the carriage, as in the'arrangement exhibited there is no pin or stop in place beyond that at the hole numbered 40. When the thelev'er is released the rackand the rockshaft are restored to their normal positions by reason of the superior weight of thehinged frame,- wh-ich is sufficient through the rockshaft, to return the lever 19 to its first posttion without the'aid of the spring 25, which is employed principally to keep the dog 24 out of the plane of the pins when the rockshaft alone is actuated in ordinary work.

The rock-shaft orlever is usually designated a release key, and this release-key may be operated independently of the key or lever 19, for releasing the carriage in ordinary work, and when so operated the key or lever 19remainsin its normal position, shown in full lines at Fig; 4. As the release key may be operated independently of the-lever or columnstop key the pins or stops 29 need not be re'mo'ved from their holes in the bar or support when the operator is engaged in doi-ng ordinary'work. WVhileI have shown only two pins or steps, there may be used as many as the work may demand.

It will be observed that the lever or columnstop=key is connected to the carriage, and that when actuated to move the dog 24 to working position, serves to operate the carriage releasing devices. It will be further observed that when the dog 24 is vibrated and the carriage released the hand isupon the column stop key (or the carriage), and hence the movement of the carriage toward the left under the force of its driving spring, maybe so regulated or controlled as that the carriage may be stopped easily, without shock, when the dog comes into contact with the pin. My invention is of course also adapted to that 'class of machines wherein a spring-drum or driving power is dispensed with, and the carriage moved step-by-step by positive means actuated through the movement of the keylevers. While I prefer to combine the release key with the column stop key, so far as-some of the features of my improvements are concerned the release key may be omitted.

Referring to the construction shown at Fig. 6, the vertical portion ofthearm1 8 of the lever is prolonged and the dog 24 pivoted-there to at 34, for a purpose which will presently appear. With the construction shown-'at'Fig. 4', it will be seen that it, while the handle is depressed and the dog isswung rearwardly to the dotted-line position shown, it be attempted to return the carriage totheright for the beginning of a new line or column, the dog 24 would strike against any pin I arranged on theright hand s-idethereofandan rest the carriage, which would necessitatea releasement of the lever 19. The construction shown at Fig. 6 is intended to obviate this releasement, and by the same it will be seenthat (in returning the carriage to the right While thedog is held in the plane of the stops by the depression of the handle portion 21) when said dog encounters the-pingit will turn about its pivot 34 and ride over said pin, and after passing the same drop to substantially avertical position. In order to prevent such tilting or vibration of the dog when the carriage ismoving to the left a'pi-n 35 is provided on the arm 18 One of the main objectsof my'inventi'on is to combine in one device a forwardly-projecting handle, by which the carriage maybe liftedto expose the line of print with means for doing column work. Heretoforethe'Remington machine h'asbeen provided at theleft hand side with atix'ed handle extending toward the operator to facilitate the raising of the carriage, which handle is also sometimes used to return the carriage toward the right when it may not be desired to use either the release-key or the line-spacing lever. In the other application filed by me'and above referred to is shown a key or lever, which performs only the function of a column stop key or lever, and which is neither intended nor well adapted to be used as a lifting means for the carriage. It being desirableto reduce the number of parts in the machine as much as possible, I have, therefore so constructed and arranged the column stop; key as that it may bereadily employed as a carriage lifter.

When used as a carriage'lifter, the handle 21 is of course caught underneath, and the dogbearing arm 18 abutting against the upper surface of the front bar of the carriage prevents any independent vibration of said lever during the turning up of the carriage about the hinge-rod 5 as a center of motion. If in turning down the carriage said lever should be vibrated it is immaterial, since upon releasing the same the spring 25 will restore the dog to its normal position out of the plane of the pins or stops.

Another main object of my invention is to combine a carriage-lifter with a carriage releasing means, so that either the lifting or the releasing of the carriage may be effected by the operation of a single device. When the handle 21 is raised the carriage is lifted and when said handle is depressed the carriage is released. Thus the combined lifting and releasing means is a most desirable construction independently of the column-stop devices, which, therefore, may be dispensed with, as may also the finger-piece of the release key so far as this part of my invention is concerned.

Another main object of my invention is to so combine the combined lifter and columnstop key with the release-key as that the release-key may be operated independently of the combined lifter and column-stop key when the pins or colurnn-stops are in place, so that the carriage may be released and moved toward the left to the desired point without interruption by the column-stops.

I do not wishto limit myself to the employment of pins and holes, as any known or suitable form of column stopsmay be employed in lieu thereof, and without departing from my invention any known or suitable form of release-key and carriage feeding mechanism may be used in place of the special constructions which I have elected to show.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a type writing machine, the combination with a paper-carriage and its feeding mechanism, of a releasing mechanism, independent of the line spacing mechanism and a carriage-lifter operatively-connected to said releasing mechanism, whereby the carriage may be either released or elevated at pleasure by the application of the hand to said lifter alone and without movinglhe paper in line space direction.
