, SPECIFICATION formingpart of Letters Patent No. 671,405, dated April 2', 1901.,
Application filed January 12, 1901. Serial No- 43,037. (No model.)
To all whom it may concern.-
Be it known that I, HARRY SHOEMAKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Telegraphs, of which the following is a specification.
This invention relates to improvements in telegraphs, and has a special reference to a type-writing telegraph which has for its main object the simplifying of the parts arid methods and dispensing with as many mechanical devices as possible by employing magnets to operate the type-wheehthe printing-bar, and the spacer.
Another object of my invention is the provision of a type-writing telegraph in which one set of batteries operate a commutator and also the type-wheel and a separate set of batteries operate the printing-bar and afterward the spacer, as will presently appear.
To attain the desired objects, the invention consists of a type-writing telegraph embodying novel features of construction and arrangements of parts,substantially as disclosed herein.
In the drawings, Figure 1 is a diagrammatical view of the entire telegraph. Fig. 2 is a side elevation of the commutator and operating-board. Fig. 3 is a detail view of a portion of the cylinder and one key. Fig. 4. is a detail view of the type-wheel and operating device. Fig. 5 is a detail view of the printing-bar and spacer and their electrical connections. i
Referring by numerals to the drawings, the numeral 1 designates the base, upon which is mounted the bearings 2, in which is journaled commutator 6.
the axle or shaft 3. Mounted upon one end of this shaft is a. driving-wheel 4, which may be driven by any well-known power, and located upon the shaft and revlu ble therewith between the bearings is the cylinder and composed of a series'of ringsor grooves 7, in each of which is mounted a stop-pin or projectibn 8. Suitably mounted below the cylinder are a series of key bars or levers 9, whose hooked ends are adaptedto engage its stop-pin on the cylinder to stopthe same at its proper place.
This cylinders surface is outer surface. of its periphery divided into equal parts to represent the difl'erent letters and numerals by means of brass teeth or con doctors 11, which are boundaries for-the insulated fiber blocks 12, fitted in the spaces between the teeth. Connected to the shaft is the wire 13, which is connected to the electromagnet 14, which is adapted to operate the pivoted spring-actuated pinion'or detent 15 to revolve the type-carrying wheel 16, journaled in bearings-17. To complete this circuit, however, a wire 18 is connected with the 'commutator br ush 19 and the batteries 20, another wire 21 'being connected to the batteries and an electromagnet 22, which has a wire 23 connecting it in circuit with the electromagnet 14. I
In type-writing telegraphs in general use a mechanical device is employed to operate the printing-bar; but I will proceed to describe the parts constituting my printing device. Pivoted so as to be operated by the electromagnet 22 is a pivoted lever 24, which is normally held against the magnet, as the impulses are so rapid and the spring 25 so weak, said coil -spring being connected to the lever. This lever is connected to the batteries 26 by a wire 27, and when released its outer end engages a post 28, having a wire 29 connected to it and the electromagnet 30, which in turn has a wire 31, connecting it with the batteries 26 and forminga circuit. When this circuit is formed, the electromagnet operates the pivoted printing bar or lever 32, which presses the paper 33 upward against the proper type, a spring 3. returning the bar to its normal position when released by the magnet. \Vhen this printing-bar is released, the spacer is operated, as the lever 2i is attracted by the magnet 22, causing .its outer end to engage the post 35, having a wire 36, connecting it with anelectromagnet 37, which has a wire 38, connecting it with the batteries 26, employing the wire 27 to complete the circuit; This magnet 37 operates a spring-actuated lever 39, provided with a (log or detent 40, which engages the ratchet-wheel l1, operatingthe spacing-roller 42,11 loose detent or dog itljipfeventing any back movement of ,theroll:
The commutator has the Fron1 description, taken in connection briefly stated it as follows:
"with the drawings, the operation of inytle graph is readily understood and its very nuand consequently the type-wheel, the type electrical upon thewheel synchronizing or registering with the type upon the key and an insulator of the commutator. At this point the electromagnet 22 releases the lever 24, whose spring 25 makes another circuit with the batteries 26 and magnet 30, which operates the printing-bar 32 and causes it to press the pa per directly against the proper type. When the typekey is released, the cylinder and commutator revolve as before, and the magnet 22 then operates the lever 24, which forms another circuit with the batteries 26'and,electromagnet 37, which operates the spacing device by moving the roll one space.
,It is evident that I provide a type-writing telegraph which is of very simple and inexpensive construction and also a very efficient and thoroughly-practical one.
