TATES UNITED CHARLES SPIRO, on NEW YORK, N. Y.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 543,1 11, dated July 23, 1895.
Application filed January 6, 1894. Serial No. 495,999. (No model.)
To all whom it may concern:
Be itknown that I, CHARLES SPIRO, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
- This invention relates to an improvement in type-writing machines; and it has for its principal object the provision of means for varying the feed of the paper-carrier so as to cause impressions to be made upon the paper at variously-separated points in a line instantly in contradistinction to the determination of the points in a line at which impressions shall be made by a repeated depression of the usual space bar or key of the machine.
In printing upon a type-writer tabular matter and matter in columns, such as statements of account, the time required to operate the space bar or key successively to bring the paper so as to make the impression in one of a series of columns or in more than one is a material matter and the strict attention required of an operator to print this class of work is exacting and fatiguing.
By my invention the work is simplified to a great degree, is expedited, and accuracy is the more easily attainable than Without the said invention.
Other objects and advantages of the'invention will hereinafter appear and the novel features thereof will be. specifically defined by the appended claims. I
In the drawings, Figure 1 is a plan of such of the principal parts of a type-writing ma chine with my improvement applied thereto as are necessary for a clear understanding of said improvement. Fig. 2 is a side elevation of the key-lever and its connections coupled with a substantially central vertical transverse section of the remaining parts appearing in Fig. 1. Fig. 3 is a sample of the work which my invention is intended to perform. Fig. 4 is a diagrammatic perspective of the separate devices comprised in my improvement, each being shown in its relative position with the others. Fig. 5 is a modification of one of the parts of the improvement.
Like letters of reference indicate like parts throughout the several views.
.A is the carriage, which is of usual construction and is provided with a projection 13 on vers the ordinary step-by-step movement of the carriage is produced in the usual manner.
From the bed or table D of the machine there projects upwardly a bearing E, in which is pivoted a lever F, one end of which passes beneath the pin O'of the pawl. The opposite endof the lever F extends toward the side of the machine and is connected by a link F to a column-printing key-leverG, having a key G occurring at any convenient point in the keyboard of the machineas, for example, at the-right-hand side thereof. The key-bar G is pivoted on a rod G2 and is connected by a spring G with a fixed part of the machine.
From the bed of the machine a riser H is formed and one end of a special rack-bar I is pivotally mounted therein, while the opposite end of said bar is'pivotally mounted in a similar riser H, which in this instance is an extension of the riser B in'which the carriage guide-rod B is mounted. The special rack-bar I may be provided with a series of teeth I, either formed integrally therewith at desired distances from each other, or the teeth- I' may be removable and adjustable upon or along the bar by any desirable construction.
different from thatof the path of the projection B on the carriage-lug A, so that it will not interfere with the ordinary step-bystep movement of the carriage unless when otherwise intentionally disposed. The plane of the rack-bar may either be below or above that of the projection B. In the present instance it is held normally above said projection by means of alever J pivoted at one end to a fixed part J of the bed of the machine, while its opposite end comes in contact with the special rack-bar in such a manner as to lift the same above the plane of the projection B. This bar-lifting lever is connected with the key-bar G in such a manner and by the link J that the free end of the lever J is maintained in an elevated position by reason of the normal position of the key-bar. The link J forms a sufficient rigid connection between the key-bar and lever to permit of the latter being normally held in its uppermost position by the normal position of the keylever assisted by the spring shown in Fig. 4, attached to the key-lever near its pivot and of usual construction and operation. The special rack-bar I is held in its elevated position by the engagement of the free end of the upturned portion of the lever J with the pin J While the bar J may impinge directly against the under surface of the special rackbar, I have instead thereof provided the latter with a pin J projecting from the edge of the special bar to serve as the connection therewith of the lever J. A coiled spring J serves as a yielding connection between the lever J and the special bar I. The purpose of this yielding connection is to permit a tooth of the bar to come into contact with and directly upon the lug or projection B on the lug A without interferingwith the proper operation of the special bar, as whenever such contact occurs the next depression of the key or of the space-bar of the machine which releases the dog from the ordinary carriage'feed rack moves the carriage and the projection B beyond the tooth of the special bar, so that the purpose of the invention is not evaded.
It is apparent that if the connection of the bar J with the special rack-bar I were nonyielding-as, for example, by a link-then when the special rack-barI, or rather a tooth thereof, isbrought to bear upon the top of the lug or projection B on the lug A'of the carriage the carriage would be held against movement, first, by the pressure of the tooth on the projection, and, second, because the key, whether spacing or letter key, could not be sufficiently depressed to relieve or remove the feed-dog from the ordinary feed-rack of the carriage. This action of the parts is hereinafter further explained.
To summarize the operation of the'invention reference is made to Fig. 3, where it will be noticed that the writing on each line is practically continuous through the first two columns, while the first character in the third column would be imprinted in its proper place when the projection B is in contact with the first tooth from the side of the machine shown in Fig. 1 of the special rack-bar. There being no entries in the sixth and seventh, tenth and eleventh, fourteenth, fifteenth, and sixteenth columns,the remaining teeth of the special bar are located so that the carriage may be continuously moved instead of step by step,
so as to carry the next required impression over these unoccupied columns and into those which are to be occupied by printed characters. In this jumping of the carriage the ordinary step-bystep feeding devices are temporarily thrown out of use, and this by the same means which temporarily brings in the special rack-bar for use. It will be noted that when the key G is depressed the lever F is depressed at its outer end simultaneously with the depression of the lever J, and this latter lever, through the medium of the yielding connection J, brings the specialbar into the plane of the projection l3 on the carriage; The depression of the key being continued, the pawl C is subsequently thrown out of mesh with the rack-bar G which frees the carriage. Under the influence of the usual carriagefeeding motor or spring the carriage moves until the next tooth of the special rack-bar stops it by contact with the projection B on the carriage. Now the key G is released from pressure and its lever rises to its normal position, and in doing so permits the pawl C to again mesh with the carriage rack-bar for ordinary step-by-step carriage-feeding, and at the same time the special rack-bar is lifted out of the plane of the projection B and ordinary printing continues until the work requires another jump by the carriage. It will be seen that a single depression of one key accomplishes what would require a multiplicity of depressions of a spacing bar or key to accomplish, and furthermore no watchfulness is required to determine at What point in the movement of the carriage to cease depressing a spacing-key, and, finally, a perfect alignment of letters or numerals vertically in the column is assured, thus facilitating the computation of totals.
I believe I am the first to produce a device for obviating the necessity of a continuous operation of the ordinary spacing devices of a type-writing machine to produce a blank space of greater length than required in or dinary solid printed matter, which obviates subjecting the ordinary carriage escapement or feeding devices to the injurious shock and wear occurring in the skip movements of the carriage, and I have shown one form of mechanism for accomplishing this purpose. Other forms will readily suggest themselves to those skilled in the construction of machines of this class upon an examination of the form disclosed herein, and I therefore do not limit my invention to the specific construction of the parts which I employ to embody the same in a practical form. I have shown my invention in connection with a particular jection independent of the rack-bar thereon,
