UNITED STATES PATENT OFFICE.
HENRY MAHNKEN, OF NEW YORK, N. Y.
PRINTING-TELEGRAPH.
SPECIFICATION forming part of Letters Patent No. 665,027, dated January 1, 1901.
Application filed. March 8, 1900. Serial No. 7,809. (No model.)
To all whom it may concern:
Be it known that I, HENRY MAHNKEN, a citizen of the United States, residing in the borough of B ronx, city and State of New York, have invented certain new and useful Improvements in Printing-Telegraphs, of which the following is a specification.
My invention relates to new and useful improvements in printing-telegraphs,and the invention relates particularly to the motor and escapement mechanisms for the type-wheel shaft of printing-telegraph receiving instruments.
The object of the invention is to provide a simple and effective motor mechanism for actuating the shaft and by which clock trains and weights will be dispensed with, whereby the improved instrument will be much more compact, it will be cheaper, the type-wheel shaft will at all times be subjected to an approximately uniform driving stress,.and it will require no attention in use.
In order that the invention may be better understood, attention is directed to the accompanying drawings, forminga part of this specification, and in which- Figure 1 is a side view of the type-wheel shaft of an ordinary printing-telegraph receiver, showing my present improvements applied thereto in their preferred construction; Fig. 2, a section on the line 2 2 of Fig. 1, and Fig. 3 asection on the line 3 3 of Fig. 1.
In all of the above views corresponding parts are represented by the same numerals of reference.
1 represents the type-wheel shaft of an ordinary printing-telegraph receiver mounted in bearings 2 2 and carrying the type-wheels 3 3.
4 is the escapement-wheel, which is rigidly secured to the shaft, and which is provided with a number of teeth, dependent, of course, upon the characters on the type-Wheels. Ordinarily the type-wheels are each provided with thirty characters and the escapementwheel with fifteen teeth.
5 represents a ratchet-wheel loosely mounted on the shaft 1 and which works against the collar 6 thereon.
7is aspring making one or two turns around the shaft 1 and connecting the ratchet-wheel 5 with said shaft, whereby the ratchet-wheel may move a limited distance with respect to the shaft. Instead of employing a coiled spring, as shown, any other form of elastic connection may be employed between the ratchet-whee1 5 and the escapement-wheel 4.
8 is a pawl-carrying yoke carried by an iron oscillating armature 9, pivoted on a pin 10, which projects from one of the poles,as shown, ofa G -shaped magnet 11, the other pole of said magnet carrying the two coils 12 12, which are connected in the line, whereby an, alternating current transmitted over the line in the usual Way will result in the oscillation of the armature 9, as is common, the arms of the yoke 8, carrying springs 13, each being provided witha feed-tooth 14, engaging with the teeth of the ratchet-wheel 5. The throw of the yoke 8 is so proportioned as to allow the alternately-operating feed-teeth 14 to feed the ratchet-wheel 5 at each stroke of each feedtooth a distance of one-half of a complete tooth on the ratchet-wheel. Assuming, therefore, that the ratchet-wheel 5 were connected directly to the shaft 1, fifteen complete oscillations of the armature 9 would be required to advance the shaft 1 a complete turn. In the preferred construction the arms of the yoke 8 carry pallets 15, which cooperate with the escapement-wheel 4, as shown, so that each complete oscillation of the yoke will allow the ratchet-wheel 5 to be moved the distance of a complete tooth.
The operation will be as follows: An alternating current being transmitted over the line in the desired number of impulses to advance the type-wheel shaft the proper distance to bring the required character to printing position the first impulse will cause the armature 9 to be rocked or oscillated in the opposite direction to that shown. This movement will cause one of the feed-teeth 14 to engage one of the teeth of the ratchet-wheel and to turn the latter a distance equal to onehalf of the distance between any two of its teeth, thereby placing the spring 7 under tension and exerting a stress on the type-wheel shaft. Immediately after this feed movement commences one of the pallets 15 will release the escapement-wheel, which will therefore be turned to a distance equal to one-half of the distance between any of its teeth under the stress of the spring 7, thereby advancing the type-wheel shaft to the suclCO ceeding character. Each impulse transmitted over the line therefore will result in the turning of the type-Wheel shaft to the successive characters until the desired character is reached.
By mounting the iron armature 9 pivotally upon a suitable bearing carried by one of the poles of the magnet 11 a very powerful mag-- net attraction will be secured upon the armature, and it is possible for this reason to employ only a single magnet for eifecting both the feed and the control of the type-wheel shaft. Obviously such a construction is simpler and better than when more than one magnet is employed for effecting these ends; but it will nevertheless be understood that the magnet 11 may be employed only for the purpose of effecting the feed movements of the ratchet-wheel 5 and that a separate escapement-magnet may be used, connected, preferably, in series with the coils 12 for effooting the feed of the escapement at.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:
1. In a printing telegraph receiver, the combination with a type-wheel shaft, an escapement-wheel connected thereto, a ratchet- Wheel loosely mounted on the shaft, a spring connecting the ratchet-wheel to said shaft, an oscillating yoke, fcedteeth carried by the arms of said yoke and engaging the ratchetwheel, an oscillating armature connected to said yoke, and means operating in substantial unison with the oscillations of the yoke for permitting feed movements of the escapement-Wheel to take place, substantially as I set forth.
2. In a printing-telegraph receiver, the combination with a type-wheel shaft, an escapement-wheel connected to said shaft, a
