PRINTING-TELEGRAPH.
SPECIFICATION forming part of Letters Patent No. 332,649, dated December 15, 1885.
Application filed September 10, 1885. Serial No. 176,658. (No model.)
To aZZ whom it may concern.-
E is the escapement controlling electro- Be it known that I, RICHARD N. DYER, of magnet acting upon a polarized armature, F,
New York city, in the county and State of New York, have invented a certain new and useful Improvement in Printing-Telegraphs, of which the following is a specification.
My invention relates to that class of stockquotation printers employing two typewheels on independent shafts, either of which typewheels can be moved to position and printed from while the other is at unison, such wheels being revolved in the same direction by independent motors which exert a constant tendency to turn them, and being controlled by escapements and by the unison-stops. An instrument of the class referred to is shown in Patent No. 290,557.
The object of my invention is to produce a more simple and efficient mechanism than heretofore employed for controlling the movements of the type-wheels from one magnetarmature.
By my invention I employ a single scapewheel and pallet, the latter connected directly with the magnet-armature and vibrated thereby. The scape-wheel is not connected rigidly to either type-wheel shaft, but is coupled with them by pawls and ratehets. The scape-wheel is turned by both shafts when both type-wheels are revolving; but when one type-wheel is stopped at its blank space or unison the shaft of the other type-wheel turns the scape-wheel alone, the pawl-and-ratchet connections permitting this to be done.
In the accompanying drawings, forming a part hereof, Figure 1 is an elevation and partial section of the mechanism; Fig. 2, a section through the scape-wheel and ratchet on enlarged scale; Fig. 3, a cross-section of a type-wheel shaft, showing escapement in elevation; Fig. 4, a section through one of the ratchets with pawl in elevation, and Fig. 5 a view showing unison-stops.
A and B are the type-wheels arranged side by side and fixed on the ends of two shafts, O and D. Shaft G is a sleeve surrounding shaft D, as shown, and Ois of less length than D. These shafts are revolved in the same direction by separate motors, (not shown,) as weight or spring trains terminating at the shafts in the pinions a b.
and serving to vibrate such armature. Armature F is carried by pallet G,which engages scape-wheel H. scape-wheel H is mounted loosely on shaft D against or close to the end of shaft 0. This scape-wheel has made in one piece with it, or rigidly attached thereto on its opposite sides, two ratchet-wheels, I K, (,0 with teeth turned in the same direction. With these ratchet-wheels engage pawls c d, carried by disks L M, secured rigidly to the shafts O D. The teeth of the ratchets are preferably the same in number as those of the scape- 6 5 wheel, and the parts are constructed and adjusted to work together, so that the pawl of a type-wheel shaft at rest will drop into a tooth at each movement of the scape-wheel. The shafts O DQare provided with radial stop-arms e f, which are intercepted alternately by dogs 5/ h on a rockshaft, N. When the rock-shaft N is turned one way, one dog is thrown into the path of travel of a stop-arm, and by the same movement the other dog is moved clear 7 5 of the stop-arm for the other type-wheel shaft, always leaving one type-wheel shaft free to turn under control of the escapement. The type-wheels have each a blank space, at which point no impression upon the paper strip will be made. The dogs 9 h are arranged to stop the type-wheels at these points.
The mechanism described is mounted in a suitable frame with the other parts of the instrument, which may be a two-wire instrument, such as described in Patent No. 290,557, with a printing-magnet supplying power to lift the platen and rock the shaft N and a neutral magnet in the type-wheel circuit with the magnet E directing the application of the 0 platen movement to the rock-shaft in one direction or the other; or my invention may be applied to any other suitable form of stockquotation printer where it is desired to control two type-wheels by one magnet.
It will be seen that since the shafts revolve in the same direction and apply their power to the scape-wheel, (instead of receiving power from it,) the stopping of either shaft does not prevent the other shaft from moving. If 100 both typewheels are at unison, the vibration of the pallet allows but one of them to turn wheels,

, and a single vibrating magnet-armature, to: :3

down to catch and stop the shaft that has been moving when it reaches unison. Both wheels then revolve together, their pawls acting jointly to move the scape-wheel, until one reaches unison,where it is stopped by the dog on the rock-shaft, while the other continues its movement to the letter or figure it is desired to print, alone turning the scape-wheel during this last period; or each type-wheel may in turn be run to unison before the rock- 1.
