C is a tubular support, of brass or other suitable material, having a smooth exterior surface. This tube serves as a support for `a tubular blank upon which the lines are printed circuinferentially around the said blank, the blank being fed or moved circumferentially and axially for the purpose. The blank itself is a sheet formed into a paper tube by cementing the edges together by any The formed tube is slid end-A rlhe lattubes at the saine time, one of such tubes y being that upon which the printing is being done, while the other is arranged in close proximity thereto, so as' to be capable of being slipped quickly into position when or about when the first paper tube is filled.
In the drawings, Fig. 26, two tubes are indicated, that one at the right being the one upon which the characters are being printed and that at the left the one which is in position to slide beneath the type-wheel as soon as the last line on the first one has been printed. The end of the supporting-tube is made slightly conical, as shown, to aid inthe ready application of the formed paper tube. Suliicient space should be left at the right-hand end of the tube C', from which end it is supported, to permit the blank when printed to be quickly slipped to one side and a fresh blank to take its place. After the latter has been moved into position for printing the first i-s removed from the tube by opening it on the line where the edges of the sheet are IIO Fig. 26, this being the axial movement of the paper tube corresponding to the feed which is necessary to make the vertical space be- -tween lines on the printed page.V
The press-pad p works through an opening lin the supporting-tube C beneath the type-wheel W. long arm of a bell-crank lever' which/is'pivoted in a bracket or frame c7, fastened within the supporting-tube C', as shown in Fig. 7, and has its short arm connected with the armature-lever o9 of the press-magnet c by a rod or wire 010 extending outside the tube C through the end thereof at which it is supported on the frame of the apparatus. The magnet is operated in any suitable manner as soon as the letter is brought into position for printing, but by preference through the action of a circuit-controller which causes said magnet to be energized once for each cycle of changes produced by a sunflower or distributer that governs the operation ofthe adjusting devices by which the type-wheel is fed into the desired positions, and as will be described farther on. The press-lever is retracted by a spring a8 applied directly thereto, instead of tothe armature-lever.
By connecting the press-pad and magnet in the mannerdescribed, the use ofa magnet of considerable size is rendered expedient and the adjusting devices for the saine rendered accessible. This would not be the case if' the attempt were made to support thepressmagnet within the tube near to the press-pad, since in practice the dimensions of the tube are limited and a magnet of considerable size would not be permissible if the same were placed within the tube. The press-magnet is mounted on a pivoted frame c5 provided with adjusting-screws c6 whereby the positions of the magnet may be changed to take up slack in the wire c10 and adjust the throw of the press-lever. The armature of the press-magnet is also provided with a suitable' contact'- spring 73, whereby when the magnet is not energized'it may close the circuit by a con'- tact-post 74, and when the magnet is enercircuit.
the paper will take'place when the press-pad moves back after making the impression.
At its lower end the armature-lever o9 is shown provided with an extra contact-spring and stop, whereby, if so desired, the said le- This pad is supported on the ver may be Vmade to close 'a local-circuit when the magnet is excited. I
Mounted on the frame of the instrument is an insulating-block g5, carrying the set of contact-springs 97, insulated from one another and adapted to be engaged by contact-pins, (indicated in dotted lines at g, Fig. 10,) 'the Ylatter being carried by the frame of the magnet c', and being connected with the two terlninalsV of the magnet and with the post 74 and armature-lever or, frame. The springs Q7 being connected to the local circuit in any desired manner, said circuits will be completed through the contacts and through the coils of the magnet when the magnet is placed in position upon the frame of the instrument. The pins g6 at the extreme right and left may be connected with the terminals ofthe coils of c', and the two pins next to them may be connected'one with the post 74 and the other be an electrical connection with the frame c5. The middle spring g7 is adapted for engagement by a projection from the contact-post beneath the magnet c', as clearly shown in Figs. 7 and 10.
To produce the circumferential feed of the paper tube it is preferable to employ afriction device directly engaging with the paper tube. This device is also, by preference, a wheel which remains in engagement with the paper during the printing of a line and is turned'intermittently to produce the letter and word spaces.
The axial feed is produced bya device which is normally disengaged and is brought into .operative engagement at the end of a line and before the beginning of the next line, the circumferential feed device being automatically withdrawn during such axial feed operation. The axial feed device also, by preference, engages directly with the paper and consists of a friction-pad made -to reciprocate after the manner of a pawl and in a line parallel'to the axis' of the paper tube.
B is the circumferential feed-wheel mounted on a shaft d whose bearings are in any suitable support adapted to withdraw the feedlwheel from engagement with the paper. This support is herein shown as consisting of the rocking frame E, which for convenience is Y D3 in the train of wheels between the feedwheel B and the devices, by which its intermittent motion is produced. To insure the proper feeding of the paper tube, an idler friction-wheel B6 may bemounted within the tubular support C with its edge arranged to rotate in an opening in said tube opposite feed-.wheel B. The paper is grasped between the wheels B and B6.- A spring dg, connected to a cross-bar at the rear of frame'E, causes the feed-wheel to grasp the paper tube with a yielding pressure. By adjusting the tension-spring and thus varying the pressure the extent of feed at each of the intermittent movements of the wheel may be varied. With a lighter pressure a longer feed will be produced,
