WILLIAM T. MGGRAW, OF DETROIT, MICHIGAN.

CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 519,922, dated May 15, 1894.

Serial No. 487,278. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM T. MOGRAW, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Cash-Registers; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to cash registers, and has for its object improvements pertaining to the registering mechanism employed in connection with what are known as tablet machines. The registering devicein machines of this kind is intended to enable the user of the machine to know, from an inspection of the register, how many times any particular part of the machine has been operated, how many times any particular tablet key has been used and its tablet exposed, and how much money ought to be found in the drawer connected with the machine to correspond with the indicating operations that have been performed on the machine.

The apparatus devised by me to produce this result consists primarily of a screw on which are a number of threaded ratchet wheels or burrs, having peripheral ratchet teeth that run on the threads of the screw, a forward motion to the ratchet wheel being produced at each indicating operation of the key in connection with which it operates. The periphery of the ratchet wheel is divided into numbers corresponding to the number upon the indicating tablet operated in connection with the same key, and at each revolution of the ratchet wheel, it advances along a scale bar which lies parallel with the axis of the screw, and indicates to the user at a glance how many times the ratchet wheel revolved on its own axis, the scale on the ratchet wheel itself indicating what part of a revo lution on its own axis theratchet wheel has made in addition to the number of complete revolutions indicated on the scale bar. There is thus at once indicated on the scale bar and the ratchet wheel the number of strokes that have been given to the key and the number of times that the indicating tablet operating in connection with that key has been exposed to view, and the operator or examiner knows what amount of money he should find in the cash drawer to correspond with the indications on the register mechanism.

Other improvements will be described and pointed out in the specification and claims.

In the drawings, Figure 1 shows in perspective a cash register with my registering device inclosed therein, a part of the front case being broken away to show the interior work. Fig. 2 is a sectional elevation showing the action of a single key on the registering ratchet wheel and the readj usting device by which the keys are released from the ratchet. Fig. 3 is an enlarged detail View of the screw ratchet wheel and readjusting bar. Fig. 4 is a sectional elevation, showinga ratchet wheel and its connection with the other parts of the register, and showing the readjusting lever by means of which the ratchet wheels are released from all holding pawls to enable the operator to turn them backward and readjust them at the zero point.

A indicates the case or shell of a register, of which the key-board (or protruding ends of the keys) is at B, and-the slot for the inspection of tablets that have been lifted for purposes of inspection is at C. I prefer to use a tablet key made in a single piece in the form of a bell crank lever having a pro= truding finger piece end 1, an interior tablet carrying end 3, and a depending register actuating end 4. These are journaled on a bar 2, which extends across the frame from end to end. The depending register actuating arm 4 extends radially from the shaft 2, and terminates at its extremity with the hardened plate 5 that travels in a circular are partially around the center of the bar 2, in an are which interferes with the line of travel of a ratchet wheel 6 mounted on a screw 10. The face piece 5 has a length parallel with the axis of the screw 10 sufficient to enable it to continue to engage the teeth ofthe ratchet wheel 6 while the ratchet is traversing the screw 10 by turning along the screw and several revolutions around it. The screw 10 itself is journaled in an auxiliary frame, of which the two end pieces are indicated at 9 and 9 (The end piece 9 is shown in Fig. 4, and the end piece 9 is shown in Fig. 2.) The two (No Model.) f 2 Sheets-Sheet 2.

ORGAN.

Q SPECIFICATION forming part of Letters Patent No. 519,925, dated May 15, 1894.

A plication filed duly 29,1893. Serial No. 481,843. (No model.)

To aZZ whom it may concern:

Be it known that I, J ERZY POLUKANIS, of Bloomfield, in the county of Essex and State of New Jersey, have invented a new and Improved Organ,of which the following is a full, clear, and exact description.

The invention relates to organs such as shown and described in'the Letters Patent of the United States No. 499,036, granted to me on June 6, 1893.

The object of the present invention is to provide certain new and useful improvements in organs, whereby the pipes can be quickly sounded to permit the performer to execute any desired passage of music in the proper time.

The invention consists of certain parts and details, and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is a transverse section of the same on the line 2-2 of Fig. 1. Fig. 3 is a sectional plan view of the same on the line 38 of Fig. 1. Fig. 4: is a sectional side elevation of the improvement as arranged for an organ of different construction. Fig. 5 is a similar view of the improvement as applied to another form of organ; and Fig. 6 is a similar view of the improvement as applied to another form of organ.

In my patent above referred to I employ a pneumatic valve having a casing and a sliding leak piston, but I find that a swinging leak piston in a casing, of which part can be adjusted to increase or decrease the leaking capacity, is more advantageous.

The improvement consists principally in a self-acting pneumatic valve provided with a swinging leak piston Apivoted in a casing B attached to the wind box 0, containing the pallets D connecting the wind box with the wind chest E connected in the usual manner with the pipes to be sounded. Into the wind box 0 discharges the trunk leading from the bellows in the usual manner. One end of the valve casing B connects by a pipe F with an exhaust valve adapted to be actuated from the keys, so as to permit air to escape from the pipe F and the pneumatic valve for actuating the leak piston A in the manner hereinafter more fully described.

The casing B, as illustrated in Fig. 1, is provided with a channel B connecting the interior of the casing containing the piston A with the wind box 0, and a second channel B is also formed in the said casing B to connect with a pneumatic action G of any approved construction, and connected with the corresponding pallet D. By this arrangement the pneumatic action G opens or closes the corresponding pallet D so as to permit the wind to pass from the wind box 0 to the wind chest E, and the pipes to be sounded. Thus, when air is released from the pipe F and casing B, by the performer manipulating the keys or pedals, the said leakpiston A is actuated by'a preponderance of air pressure from the wind box 0, to connect the latter with the pneumatic action G or to connect the latter with the outer air so that the pneumatic action actuates the corresponding pallet D. The latter is thus opened and air from the wind box 0 passes to the wind chest E to sound the pipes.

The leak piston A may be of various constructions, some of the principal forms being illustrated in the drawings, the construction of the piston depending to a large extent on the special construction of the pneumatic action Gand its location, either inside or outside of the wind box 0.

As illustrated in Fig. 1, the leak piston A is pivoted at A within the casing B, and its free end is connected by a rod H with a valve I, adapted to open and close the channel B leading from the channel. 13 to the outside. This valve I is hinged on the outside of the casing B, as plainly illustrated in Figs. 1 and 2. The free end of the leak piston A, when in its normal position closes the channel B while the lower end of the channel B is open, and when the leak piston A swings upward on the reduction of air in the pipe F, then the valve I closes the channel B to permit air to pass from the wind box 0 into the channel B to the pneumatic action G, so as to cause the latter to open, whereby the corresponding pallet D is open and air can pass from the wind box 0 into the wind chest E,

and to the pipes to be sounded. As soon as the reduction of pressure in the pipe F ceases, the leak piston A again closes, so that the valve I opens,it being understood that a sufficient amount of air leaks past the piston A from the channel B and channel B to permit the said piston to seat itself and to close the upper end of channel B In order to increase or diminish the leakage between the piston A and the sides of the casing B in which the piston is located,Iprefer to make one of the parts of the casin g containing the piston adjustable, so as to move this part nearer to or farther from the corresponding edge of the piston A. As shownin Fig. 1, the movable part B of the casing B is held on a screw J, mounted to turn in a fixed portion of the casing B. The head of the screw extends to the outside of the casing, so as to permit the operator to conveniently apply a suitable tool such as a screw-driver to turn the screw in its bearings, to move the movable part B inward oroutward, nearer to or farther from the corresponding edge of the piston B, thus decreasing or increasing the leakage of the piston and the casing.

As illustrated in Fig. 4, the piston A is pivoted near its middle in the casing A, and the pipe F connects by a channel B with the under side of the free end of the said piston so that a reduction of pressure in the pipe F causes this endof the piston to swing downward,while the other end rises to uncover the channel B connected with the channel 13 leading to the pneumatic action L. At the same time, this end of the piston A causes a closing of the valve I on the lower end of the channel B leading to the channel B As soon as the reduction of pressure in the pipe F ceases, the piston A swings back to its normal position, thereby opening the valve I and closing the upper end of the channel 13 leading into the interior of the casing A, at the same time connecting the channel B with the lower and now open end of the channel B leading to the outside.

As illustrated in Fig. 5, the pneumatic action G is located within the wind box 0 and directly connected with the pallet D. In this case the valve 1' is of disk-form and, is adapted to be seated on seats B and 13 formed within the channel 13 at its junction with the channel B Now, when a reduction of air pressure takes place in the pipe F, one end of the piston A swings downward while the other end carrying the valve I swings upward to permit the valve 1 to seat itself on the seat 13, thus connecting the channel 13 with the channel B leading to the outside. Air within the action G now passes to the outside, owing to the preponderance of pressure of air in the wind box 0, so that the pallet D held on the pneumatic action is opened and air passes to the pipes.

As shown in Fig. 6, the pneumatic action is entirely dispensed with and the piston A is directly connected with the pallet D. Now when air is exhausted through pipe F, the piston swings downward thereby opening the pallet D to permit the wind to pass from the wind box 0, to the wind chest E and the pipes.

It will be seen that by this arrangement the pallets will respond instantaneously to the action of the air pressure on the manipulation of the keys, so that the pipes can be very quickly sounded and any desired passage of music can be executed in the proper time.

Having thus fully described my invention, Iclaim as new and desire to secure by Letters Patent 1. In an organ action, the combination with the pallet, D, opening downward, and the easing, B, of the swinging leak piston, A, which is separated by a narrow space, at one side, from the adjacent side of the casing, so that air may leak past said piston to permit it to seat automatically and thus close the communicating air passage, as and for the purpose specified.

2. An organ, provided with a pneumatic valve, comprising a casing having an adjustable part, and a leak piston mounted to swing within the said casing and arranged to permit air to leak between the adjustable part and one end of the piston, substantially as shown and described.
