This invention relates to improvements in telegraph transmitters and particularly to the construction of a transmitting machine provided with a key board with the characters on the keys arranged in any predetermined manner to permit of the convenient operation thereof in the transmission of signals. y
An object of the. invention resides in providing a telegraph transmitter having va housing in which is mounted a transmitting mechanism composed of a pluralityof independently operated disk members adapted to step by step movement and in said movement to send a signal impulse by telegraph,v
a suitable keyboard mechanismV comprising a plurality of independently operable keys similar' to the keys of the'typewriterbeing provided for'moving the disk independently through a separate movement upon depression of the keys in order to send a signal` indicating a telegraph.
A further object of the invention includes the provision of a telegraphic transmitter by which code signals may be sent by Atele-` graph through the operationk of suitable keys forming a keyboard of the instrument predetermined character by so that it is not necessary for the operator* to be familiar with code transmission order to senda message,k and in addition signals may be sent more rapidly and uni? formly than by the manual operation, of a" spinning key. y
The invention comprehends numerous other objects and improvements residing in the details of construction and the relation of the parts which are more particularly pointed out in the following detailed description directed to a preferred form of' construction, it being understood, however, that various changes may be made in the size, shape and arrangement of the parts for carrying out the invention, without departing from the spirit or scope of the same as herein set forth.
In the drawings forming part of this application Figure l is a side elevation of the im-V proved transmitter construction forming the subject matter of this ,invention showing portions broken away and in section.
Fig. 2 is a plan view of the improved i transmitter showing portions broken away and in section.
Fig. 3 is a detailperspective view of one of the circuit makers carried bythe disk members operable for sending signal im-v pulses in the rotation ofthe disk member.
Fig. 4 1s a diagrammatic view illustrating mi a complete telegraph circuit inthe manner in which the disk member operated through one step of movement cooperates with a stationary member for sending acodey signal operating a receiving instrument in accord ance therewith.
A housing is indica-ted at l which isv pro.- videdwith a plurality of successively stepped portions as indicated at 2 associated with each stepped portion are a row of keys 3. This construction of the housing and the mounting of the keys places the keys in diskV member for each key 3. A plurality of horizontal partition walls Gare mounted in the housing in a predetermined spacedV relation `under Aeach of the shafts 4 andon each /of .these partition walls within the plane of the disk 5 are mounted a plurality of supporting plates 7 of suitable insulating material. These plates are also securedto the inside walls of the-housing. All of the' plates'f? are formed with substantially semi-` circular recesses 8 vwhi'chlie in concentric relation with the periphery of the disk 5, and in the central portion are adapted to receive and support the contact members 9, 100
which are provided with common circuit `connection through the rod members l0 extending from end to end in the housing and in spaced parallel relation to respective shafts 4 of the row of disks with whichthey 105 are associated. Y
A plurality of curved or arcuate contact springs 11 are mounted on the periphery of y the disks 5 in equal spaced relation and intermediate the mounting. for the'i contact 110 sa 'Y members 5 mounted thereon, there being. one
lil
springs 11 the periphery of the disk is formed with notches 12 in which the pawls 13 carried on the under side of each key 3 is adapted to seat so that in the depression of each key 3, the disk associated therewith will be rotated one step which will move one of the contactsprings 11 over the stationary Contact spring 9 of one end to the other thereof for making the circuit control byV 3 so that the operation of the lever Vor keys from one end of the slot tothe other forms one step of movement for the disk 5 in order u to producean operation for sending in code the signal impulse for a certain-character.
f The reverse rotation of the disk 5 is prevented through the cooperation of the contact springs 11 with the surface 8 of the insulating platey members 7.
The stationary contact plates 9 are formed with recesses 16 in the contact face thereof adapted to cooperate with the contact springs 11 so as to divide the contact face into a plurality of projections of varying lengths for representing dots and dashes of the telegraph code. It will thus be appreuciated that the operation of one of the disks 5 through'one step of movement will move one of the contact springs 11 over all of the contact portions of the stationary contact pla-tesv 9 associated ,therewith and thus send a series of dots and dashes over the telegraph line representing the code signal for the character of the key depressed for operating the relay 17 illustrated in the diagrammatic view in Fig. 1in accordance Y with the impulses sent over the line 18.
The sounder or relay 17 may be replaced by any other suitable mechanism such as is at present used in the art for receiving and recording messages in a well known manner.
With a transmitter of this character, it will be seen that inexperienced operators who maybe familiar with the key-board are able to send a telegraphed message in a quick and e'liicient manner which will operate a suitable reproducing or recording mechanism at a receiving station where the message is recorded. As shown in Fig. 1, the rods 1() are all Vconnected at one side of the circuit,`\vhile the shafts 4L are connected in the opposite side of the circuit so that the disk 5 and co-related stationary contact 'mem.
bers independently control energization of the circuit in the operation of the recording mechanism therein.
Having thus described my invention, what I` claim as new is A telegraph transmitter, comprising a housing having a stepped front wall portion, a plurality of shafts mounted in predetermined relation in the end walls of said housing, a plurality ofjgroups of lever keys pivotally mounted` at one end in spaced relation on said shafts and projecting through slots formed in the stepped fr'ont Wall of said housing adapted to limit the operation thereof, said lever keys being independently operable,-means for normally holding said lever keys in aV predetermined position, a plurality of disk members'v mounted on said shafts for relatively independent rotation, one of said -disk members being associated with each lever key, ratehetmeans carried by each lever key for engagementwith its respective disk members Vfor rotating said Vdisk member in a step of movement in one operation of the key, a plurality of insulating plates mounted in predetermined relation in said housing and corresponding in number to said disk members, stationary contact plates mounted on said insulating' plate members, said stationary contact plates being formed in a predetermined manner to Y represent code signals of predetermined characters, and contact springs mounted on said disk members in a predetermined manner for engagement with said stationary plate members and operable in one step of movement to engage all of the contact portions of said stationary plate members` for energizing a telegraph circuit in a predetermined manner to send the code signal lfor the character represented thereby.
In testimony whereof I aflix my signature.
