NITED STATES PATENT @rrroa PRINTING-TELEGRAPH RECEIVER.
SPECIFICATION forming part of Letters Patent No.
Application filed February 9, 1885. Serial No.155,328.
T 0 all 2071,0172 it may concern.-
Be it known that 1, WILLIAM J. MoOAUs- LAND, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Printing- Telegraphs, of which the following is a specification.
My invention has reference to printingtelegraphs; and it consists in certain improvements for driving the type-wheel in which a wormwheel rotated by a mechanical motor revolves a worm-wheel fixed on the type-wheel shaft; further, in a unison controlled by the same electric current which operates the press-armature, the side unison being separate and distinct from the type-wheel or its shaft or the printing mechanism, and in many details of construction, all of which are fully set forth in the following specification and shown in the accompanying drawings, which form part thereof.
The object of my invention is to construct a positively and quicker mechanism for controlling and actuating the type-wheel of a printing-telegraph receiver, and is an improvement upon Letters Patent granted to me June 3, 1884:, and numbered 299,664.
Figure 1 is a side elevation of a printingtelegraph receiver embodying my improvements. Fig. 2 is a front elevation of same. Fig. 3 is a perspective view of the electric motor which operates or rotates the motorshaft.
A is a type-wheel shaft, A is the typewheel, 13 is a worm-wheel, (J is the printingarmature, and D is the press-magnet which are operated by an electric battery, X, from which the current is transmitted over the linewire V, and the pulsations controlled by the key VJ or other suitable device. 1
F is the motor-shaft, and is provided with the worms E O, the former gearing with the worm-wheel B on the type-wheel shaft, and the latter gearing with the auxiliary wormwheel 1?, having an independent shaft or bearing. The shaft F is provided with a crank, G, to which is pivoted or journaled the pitman H, hinged at its upper end to a pivoted bar, I, journaled at 2', which bar is vibrated by a rod, K, and armature K,actuatcd by the elec- 339,31Z, dated April 6, 1886.
(No model.)
trio magnet L. The spring J acts upon the bar I to draw the armature K away from the electric magnets L and keep the crank Gto the upper side of the shaft F.
To prevent the shaft F from stopping on dead centeiyit is furnished with the lugs M M, against which the pallets or arms N N press, being drawn against them by springs 92- a. The pallets an and logs M M insure the crank G passing sufficiently over the dead-centers that,when the armature K is drawn down by the electric magnets or is caused to rise by the action of the spring J, the rotation of said crank and its shaft F will always be in the same direction. This mechanism for driving the shaft F is embodied in the patent hereinbefore referred to, and also in a pending application filed by me June 28, 1884. Therefore I do not claim this said construction in the application, and I would here remark that while I prefer this motor for rotating the drive-shaft F, I wish it to be understood that it is immaterial to my invention how or in what manner the said shaft is rotated. The
worm-wheel P has a finger, Q, which, as the wornrwheel rot-ates, sweeps a given circle and makes one revolution with every revolution ofthe type-wheel, the worms 0 E and the worm-wheels I B being so proportioned that this result is attained.
R is a unison and armature-lever, and is actuated by an electro-magnet, U, located in the printing-magnet circuit V, so that every time the press-magnet is magnetized the unisonmagnet is also magnetized. The upper end of the armature-lever R is provided with a pivoted Lshaped piece, S, and pivoted to r and provided with the feet S, to allow of slight play in either direction, in the plane of the worm-wheel I, and normally is thrown forward toward the approaching finger Q by a small spring, T.
Ois apivoted paper clamp-lever, and has its bottom roughened and its upper part provided with lugs 0, between which the pin or lug c on the press-lever G works, which in its up ward movement rocks said lever C, so that its bottom is raised from off the paper D. Now, as the press-lever O descends it forces the paper under the lever G, and just before coming to rest the pin 0 strikes the other lug, O and presses the bottom of the lever 0 down tight upon the paper, the said lever being held by friction or otherwise in either position it may be made to assume. The paper being now .held by said clamping-lever O, the next upward movement of the lever 0 causes more paper to be drawn off the reel and afresh surface presented to the type-wheel.
The operation is as follows: As the shaft F is rotated it rotates the worm-wheels B P with uniform velocity, and may be so constructed that a seini-revolution or a complete revolution will cause the type-wheel to present a new letter on the printing-pad. In the unison which operates by the finger Q rotating around until it is arrested by the stop S, which it presses forward until the foot S arrests it, then a further attempt at rotating the shaft F is prevented, thereby insuring the type-wheel to be brought to unison. Upon actuating the press-arm atu re the armature-lever R will also be actuated, which action raises the piece S until it clears the finger Q, at which time the spring T forces it back tothe rear of said finger Q, so that when the lever B is allowed to fall it no longer obstructs the movements of the finger Q, and hence the rotation of the typewheel itself. It is self-evident that this unison might be used upon the machine in which the type-wheel shaft is driven by a spur-wheel and pinion, or both worm-wheels B I? may be rotated by the same worm E directly, or indirectly by gearing the said worm wheels together, therefore I do not limit myselfto the details of the construction.

1. A type-wheel provided with a wormwheel secured thereto, in combination with a worm adapted to rotate said worm wheel, substantially as and for the purpose specified.
