FRANK ANDERSON, OF FEEKSKILL, YORK, ASSIGNOR TO THE AMERI- CAN RAPID TELEGRAPH COMPANY, OF CONNECTICUT.
TRANSMITTER FOR AUTOMATIC TELEGRAPHS.
SPECIFICATION forming part of Letters Patent No. 265,212, dated September 26, 1882,
Application tiled January 13, 1882. (No model.)
To all whom it may conoerm' Bc it known that I, FRANK ANDERSON, of Peekskill, in the county of Westchester and State of New York, have invented a new and useful Improvement in Transmitters; andI lo hereby declare that the following is a full, clear, and exact description of the same.
My invention relates to automatic telegraphy, and more particularlyY to that part of the transmitting apparatus in an automatic tele- 'graph which carries the circuit-controlling tilto move slightly faster than the contact-wheel,
for purposes hereinafter explained.
The second part consists of an automatic belt-loosener, by means of which the belt connecting the winding-drum to the shaft of the carrying-wheel is made to slip when increased strain is put upon the fillet.
The third part consists of an improved fo of the reel.
Figure 1 is a side elevation. Fig. 2 is an end elevation. y Fig. 3 is the same as Fig. l with parts in an open position. Fig. 4: is a side sectional view of the reel shown in Fig. 1.
A A represent the general frame of the machine, which may be of a solid block of wood or amore open frame of metal.
B is the carrying-wheel, which may be covered with rubber, or more durably with leather, that it may take a rmer hold of the paper. This wheel is placed on a shaft, b, which extends to rear of machine, and which is provided with a drivin g-pulley, G; or, if much speed is not required, a crank on prolongation of shaft may be used.
C is a pressure-roller, mounted on lever c, which is pivotcd at o', and is kept in-contact with B by spring c.
l) is the contact-wheel, covered on its pcriphery with platinum or other suitable metal, mounted on a shaft, d, which extends to the back of machine.
H is the contact-brush, held in place in one end of the arm H by the screw I. The arm is pivoted at h by a pin which runs through to back of machine.
Either the wheel D or the brush must be iu- 6o sulated from the rest of the machine; or, if desirable, both may be insulated, connection from brush being taken 0E at the spring i, Fig. 2, and from the wheel D at d. If a double contact -wheel is used, the two connections ot' 65 wheel may be taken off at d d.
The wheels D and B are preferably made without ilanges to guide the paper, the frame of the instrument on one side and the stationary plate F F on the other serving much 7o better to keep the paper in place.
Paper is supplied by the roll W, passing thence under Y, then over D to B, between B and C to the winding-reel.
It will be seen that the motion of the paper imparted by B will tend to revolve the contactwheel D with it; but as such a result would not be the most favorable for good contact at high speed, on account of the presence of dust., libers,&c. Iprovidethe shaftdofwheelDwith So apulley, E, and the shaft f with the smaller pulley, E, and connect the two with a belt, e e, as shown in Figs. l and 2, or, in lieu of pulleys and bolts, toothed wheels and an intermediate, the action of which is to cause the contactwheel to move slower than the paper, the result being that the paper is caused to hug tightly the part of the wheel it touches, and the wheel is also kept bright and clean by the sliding paper. These two objects might be ac- 9o complished by making the wheel D entirely stationary; but in such a case the contact with brush would be made in one spot, which would soon become unfit for a good contact, (the latter requiring a rubbing of surfaces,) while by 9 5 giving the wheel a slower motion than thepaper all these points are secured.
To provide for the winding of the paper fillet as it is delivered by the carrying-wheel, the reel R R is .placed in line with carrying- 1o@ wheel, and has on its spindle a pulley, N, around which passes a belt, O, which also passes loosely on the spindle n.
in the disk T.
around pulley B on main shaft. The reel is provided near its center with a series of pins, r r, forming a core on which to wind the paper.
It is evident that if the reel runs at a uniform speed it will require more and more paper at each succeeding revolution on account of the increasing diameter of the roll, and it' the wheel B runs at a uniform rate the paper will either be broken as the size of the roll increases or it will cause the belt O to slip; but it' the belt is tight enough to drive'the reel as it should the paper would generally be broken. To remedy this the lever Q is pivoted preferably on the spindle N of the reel. On the longer arm of this lever is the idle-roller q, and on the short arnnp, is the idler P. The lever Q may be Weighted or held by a spring in about the position shown. Then the idler P rests on and takes up the slack of the belt O, the' spring beingjust strong enough to cause the belt to drive P. The paper llet, as `it leaves B, passes Linder the idler q on its way to the reel, as shown. Owing to the leverage ofthe long arm Q, the paper is amply strong enough to overcome the spring and lift g whenever strain is brought upon it.
It will be seen that so long as the paper is not Wound up faster than it is supplied the lever Q, will remain quiet in position, as shown 5 but as soon as by the increase of the roll an undue strain is brought on the paper the idler q will be lifted, carrying also the idler P, until the tension ot` the belt islessened, so as to carry the reel only as fast as the paper is supplied.
In fast telegraphy the delay occasioned by the time consumed in manipulating instruments is an important element to get rid of.
To save time in'detaching the paper from reel, the following device is used: The hub S of the reel-flange R is made large and hollow, as shown in Fig. et. This hub is made fast to the spindle a, by which the reel is driven. Within the chamber s is loosely fitted the disk T, which has a sleeve projecting through the liange R, this sleeve and disk being supported The pins r r pass loosely through the flange, and are secured A spiral spring on the sleeve bears against the liange R at one end and against a collar on sleeve at the other, and tends to keep sleeve, pins, and disk in position shown. Pressure on the end of the sleeve forces the disk T backward, withdrawing the pins from the paper roll, leaving the latter free to be removed.
To further save time in manipulation of the instrument, la lever or crank, K, is pivoted to the frame at 7c. A link,j, connects the brusharm H with the crank at l, and a link, L, connects the point l of crank with the sliding bar M at in. The farther end of the bar M abuts against lever o of pressure-roller C, as shown in Fig. l, when the crank is in its closedor upward position. Fig. 3 shows the position of parts when the crank is turned down about ninety degrees, or to its open7 position. In the lat-ter position, it will be seen, the brush is thrown up and the pressure-roller C backa position in which everything is in readiness for matter.
Having thus described my invention, what I claim isl. In a transmitter for automatic telegraphs,
a contact-wheel, a separate carrying-wheel, suitable pulleys, and a connecting belt or gearing, substantially as described, adapted to give the contact-wheel slightly slower motion than that otl the carrying-wheel.
2. In combination with a transmitter, a winding-reel, R, geared to the transmitter by belt or friction device, and the lever Q and idlers q and P, all operating as snown.
3. A reel for winding the llet, consisting ot' the ange R, shaft n, hollow hub S, disk T,
, carrying pins i", projecting through holes in R,
said disk having also the sleeve and spring, the parts being constructed, and connected to the carrying-wheel, all substantially as described.
In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
FRANK ANDERSON.
