RECORDING MECHANISM.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed July 2'7, 1908. Serial No. 445,637.

To all whom it may concern:

Be it known that I, CLYDEE. W. GARDNER, a citizen of the United States, and residing tain new and useful Improvements in Recording Mechanism, of which the following is a specification.

My invention relates to devices for recording numbers and items, and more especially to that class of recording mechanisms where a series of carriers su port each a plurality of numbered type an are brought by suitable means into proper relation to a platen to bring the desired type in printing line opposite said platen, and my invention consists in means whereby the printing of ciphers at the left of those type which are set to printfigures is prevented, and whereby the proper automatic printing of ciphers to the right of the carriers set to print figures may be effected. My invention further consists in means whereby to divide the series of carriers at will into two or more independently i operable sections, all as fully set forth hereinafter and as illustrated in the accompany ing drawing, in which:

Figure 1 is a side elevation of a recording mechanism embodying my improvements and showing parts of an adding machine; Fig. 2 an enlarged view illustrating the parts in different osition; Fig. 3 a rear view showing the re ation of the catches to each other; Fig. 4 a modification.

The recording means requires essentially a platen, a series of movable type carriers, each supporting a plurality of type, means for bringing the type in a printing line into ac-v tion upon the paper upon the platen, and means for operating the parts in proper time to effect the desired results. These parts but I have shown the same in connection with a construction of recording means substantially, in may respects, like that of Letters Patent ranted to W. H. Pike, J12, No. 763,692, am? wherein there is a cylindrical platen 880, a series of type carrying levers 403, swinging upon a shaft 420, and to each type carrier a series of keys 201, the stems of which may be set in position to be met by stops 430, upon strips 404, sliding horizon tally and pivoted at their rear ends to the lower ends of the type carrying levers, these parts being all so arranged that the depressing of any key will so limit the sliding movement of the strip 404 that the associated type carrier will move only to a position to bring into printing position the type that corresponds in value to the key depressed.

The type carriers are carried into printin positioh each by means of a spring 404 an are carried out of printing position by means of a cam 900, upon a working shaft 922, which cam bears upon the antifriction roll of the swinging frame 400, all as set forth in the aforesaid Letters Patent to Pike, and as the above particular construction and mode of operation are not essential to my improvement, and as the construction and mode .of

operation are fully set forth in the aforesaid Pike patent, it is not necessary here to go into more specific details, except to refer to the fact that at the beginning of each movement of the shaft 922 each carrier will swing to a position limited by a stop 430 contacting with a detent 205'to bring the type which prints a cipher into printing line.

In com ination with the movable type carriers and means for adjusting the same to different positions at the will of the operator, and-for automatically carrying them to position to print ciphers, I make use of reciprocating catches D, which engage shoulders or projections upon the carriers and serve to draw them back each one step to carry them out of printing position and avoid the printing of ciphers, and I provide means whereby each of said catches is prevented from so engaging and drawing back a carrier whenever the latter has been moved from the action of a key, or otherwise, to a sufficient extent to print a figure instead of a cipher. As shown the catches are all pivoted to a cross-bar 2, carried by a swingin frame G, and are provided with hooks or s oulders 3, for engaging lugs 4, upon the sides of the carriers, each catch having anextended horn 5, with a beveled face, and a cross-bar 6 of the fi nne G limiting the backward swing of the catches, These arts are so constructed and arranged that a ter a carrier has been set forward in position to print a cipher, the swinging of the rame G in the direction of its arrow, Fig. i, will bring the hook 3 of the catch into engagement with the lug 4, and as the frame continues its movement will draw back the carrier out of printing position. I f however a carrier has passed beyond the position req uired to printa cipher, to any of the posi- I engage the lug 4, but the horn 5 of the catch will rest upon this lug and no movement will be imparted to the carrier, while the catch is prevented from swingin backward.

From the above it will be'seen that when a carrier is set, as the result of depressing a key, in position to print a figure, no eifectzwill be produced upon the carrier by a movement of the catch, but all of those carriers that occupy positions to print ciplrers" will be in such re ation to the catches as to be engaged by the same and drawn forward out of printing position, and therefore no ciphers will be printed at the left of the figures which may be printed to indicate an item.

If no other provision than that above de scribed was made it would follow of course that all carriers at the right set in position to print ciphers would also be drawn forward and no ciphers would be printed at the right of the said figures, and to avoid this result I provide means whereby when any catch is eld up, as the result of the movement of the associated carriers to position to print a figure, all of the catches at the right thereof 1 I will also be held up so that none of them can act to draw forward the carriers which are in position to print ciphers and have not been acted upon as the result of setting the keys. '1 his result is secured by providing each catch D with an car it, which is bent to the right to such position as to obstruct the backward swing of the next catch on the right and thereby all of the catches on the right of any one of those held in forward position by a carrier, will be prevented from swinging backward and engaging the lugs of the associated carriers. Each of these ears maybe bent to the right to such an extent as to occupy a osition back of the rear edge of the next catc 1 as in Fig. 4, but in Fig. 3 I have shown an arrangement whereby instead of bearing upon the said edges one or more of the catches may be provided with a movable bearing in the shape of a pivoted arm F, which may be swung to such a position (and there held by friction) that its rear end will serve as an abutment for the ear of the next catch upon the left, with the same effect as if the said ear bore upon the edge of the catch itself, but with the advantage that by swinging this lever upward the next catch upon the left will have no bearing upon the catch provided with the lever, and as a result the said catch will be allowed to swing to the rear and engage and draw back the associated carrier and carry it out of printing position, and all of the other catches at the right of this catch will be capable of the same operation:

type carriers into two sections which practically act independently of each other and in each of which any desired item may be printed independently of the other. It will be evident that the catches may all be provided with the adjustable abutments or bearings, or that where the line of division is to be permanent (when the series is to be divided) the movable bearings may be only at one or more definite point 1 It will be understood that the arms F, in the construction of the machine corresponding to that of the aforesaid Pike patent, will be accessible so as to be shifted to different positions upon removing the casing of the machine.

While I have described the type carriers as consisting of oscillating levers it will be evident that they may be of any of the usual constructions, and that different means may be employed for imparting to them the desired movements and that the catches may be differently constructed and arranged to effect the results above set forth.

One means of imparting movement to the frame G is shown as embodying a rock-shaft 8, carrying an arm 9, which contacts with a roller 40 upon an arm 10 upon the shaft 12 of the frame G, the latter being swung in the desired direction when the shaft 8 rocks in the direction of its arrow, bringing the arm 9 in contact with the roller of the arm 10, the reverse movement being imparted to the frame G by a spring 13, and a stop 14 limiting this movement.

Any suitable means may be employed for operating upon the type 490, carried by the carriers, so that those in printing line will be caused to embrace the paper upon the laten, but I have shown strikers 501 whic i operate upon all the type in printing line, the latter being movable upon the carriers, as in the aforesaid Pike patent. As shown the strikers are carried against the type by the action of springs 580. The strikers are raised out of printing position by means of a restoring blade 17 carried by the shaft 8, the edge of which blade, as the shaft rocks in the reverse direction of its arrow, is brought against a tail 18 of each striker. As the reverse rocking of the shaft 8 cannot be so rapid as to pro )erly release the strikers, and as it is desirable to prevent the strikers from operating until after all of the carriers have been set to proper position, I combine with the strikers and restoring means a detent P, consisting as shown of a blade upon a rock-shaft 19, which is moved in one direction by a spring 20 against a stop and which has an arm 21, adapted to contact with a lug 22, projecting from the arm 9. These parts are so proportioned and arranged that the shaft 19 will not be rocked sufficiently to carry the blade or By this means 1 split or divide the series of i detent P away from the ends of the tails 18,

until the arm 9 has swung the shaft 12 sufficient to carry all of the catches with their associated type carriers forward out of printing position, when the detent will escape from the tail and the strikers will be brought against the type and make the desired impression.

In the illustrated construction and arrangement the parts are operated from the shaft 922, through the medium of a connecting rod 30, ivoted to an arm 31 upon the shaft, and a so to an arm 32 upon the shaft 8.
