CASH-REGISTER AND ATTACHMENT.

Specification of Letters Patent.

Patented June 25, 1907..

Application filed October 31, 1906. Serial dlfl lel To (0Z7- whom it may concern:

Be it known that I, HARRY T. WATsoN, a citizen of the United States,residing at Tacoma, iii-the county of Pierce and Statelof Washington, have invented certain new and useful Improvements in Cash-Registers and Attachments Therefor; and I do hereby 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 appertains to make and use the same.

The present invention relates to an attachment for cash registers or similar machines whereby an audible sound is produced when one of the keys is depressed, the said sound being of such a nature as to indicate the amount of money which should be placed in the drawer.

The object of the invention is to provide a device of this character which is extremely simple in its construction and operation and which will not in any manner interfere with the rest of the machine.

To this end the invention comprises essentially a series of bells, a hammer for each of the bells, the said hammers being mounted so as to have both a sliding and swinging movement enabling them to be swung against the bell and moved longitudinally into and out of engagement with the finger lever, and means whereby the hammers are operated through the agency of the keys.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings :Figur 1 is a top plan view of a series of keys and the sound attachment employed in connection therewith. Fig. 2 is a side elevation, the position of the key and hammer when the former is depressed being shown in dotted lines.

Ifig. 3 is a top plan view showing a modifica tlon.

In the embodiment of the invention shown in the accompanying drawings, the numeral 1 designates the keys which are pivotally mounted at their intermediate portions upon the fulcrum bar 2, the outer ends of the keys being provided with the ordinary finger pieces as indicated at 3, While the inner ends of the keys are formed with lateral projecting lugs or pins 4.

A frame 5 is located in the rear of thekeyboard and comprises the two end portions 6 connected b t the sides 7 and S, the inner side 7 being in the nature of a bar which serves as a rest for the hammers 9 to be hereinafter described. Extending longitudinally across the frame 5 is a rod 10 having a series of bells 11 mounted thereon, the said bells being' of such a nature as to give different rings, or rings which can be distinguished from one another. In the present instance this result is accomplished by employing different sizes of bells, the said bells gradually increasing in size from one end of the frame 5 to the opposite end. A second rod 12 extends lon gitudinally across the frame 5 and serves as a fulcrum upon which the hammers 9 are pivotally mounted. The outer ends of the hammers 9 are curved upwardly and provided withthe slappers 13 designed to strike against the bells 1 1. The inner ends of the hammers 9 are designed to engage withthe adjacent ends of corresponding levers 1, and to be elevated so as to carry theclapper 13 away from the bell when the finger piece 3 on the said lever is depressed.

In the preferred form of the invention shown in the drawings, the inner ends of the hammers 9 are operated through the medium of the lateral projecting pins 4 upon the finger levers 1. In order to enable the'hammore 9 to have a sliding as well as a swinging movement the same are formed with longitudinal slots 14 through which the fulcrum bar- 12 extends. Each of the hammers 9 is provided with a spring 15 which normally draws thesame inwardly so that the inner ends of the hammers lie in the path of the pins 4 upon the corresponding linger levers 1. The upper portion of the inner end: of each of the hammers 9 is beveled, as seen at 16, and the hammers are of such a length that when the finger lever is depressed a sufficient amount to operate the mechanism of the cash register the pins 4 will slip over the ends of the hammers 9 and permit the clapper 13 to be thrown against the bell. This latter movement is in the present instance due to the fact that the springs 15 have an inclined position and tend to pull the inner ends of the hammers downwardly as well as inwardly. When the finger levers 1 are brought back into normal position the lateral projecting pins 4 engage with the beveled ends 16 of the hammers 9 and cause the same to move longitudinally until the pins assume their mal position, as indicated infull lines in Fig. 2.

In the modification shovm in Fig. 3 an intcrmediate finger lever l is shown. as arranged between a uair of linger levers 1" which are similar in ccnstruction to those previously described, and operated in an identical manner to ring the bells 11 through the medium of the hammers 9. The hammer 9 corresponding to the linger lever 1. is not provided with a clapper, but has across-piece 17 secured thereto which engages with the hammers 9 on opposite sides thereof. It will thus be seen that when the intermediate lever 1 is depressed the hammer 9 will operate through the cross-bar 17 to ring the two bells ci'irresponding to the outer levers 1 In Fig. 1 will be observed that the finger lever 1 pro vidcd with. the linger piece 3 having marked thereon. is provded with a lat eral projecting pin 4 on each side thereof, each of which operates througl'i a corresponding hammer to ring a separate bell.

From the foregoing description it'will be apparent that the essentialleature of the in vention resides in the provision of a series of bells each of which has an individual sound, and is adapted to be rung by a certain finger lever. By the construction shown in Fig. 3 the number of bells can be very greatly decreased owing to the fact that he intermediate levers do not have a separate bell, but ring the two bells, on opposite sides thereon.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is r- 1. in a device of the character described, the combination of a finger lever, a sounding device, and a hammer operated by the finger lever an d having a pivotal movement enabling it to be swung against the sounding device, and also hav in a sliding movement enabling it to be brought into engagement with the linger lever.

2. in a device of the character described, the combination of a finger lever, a sounding device, a hammer operated by the finger le ver and having a pivotal movement enabling it to be swung against the sounding device, and alsohaving a sliding movement enabling it to be moved longitudinally into engage' ment with. the finger lever, and means for holding the hammer normally in operative position.

3. in a device of the character described, the combination of a finger lover, a sounding device, a hammer for operating the sounding device, the said hammer having a pivotal movement enabling it to be swung against the sounding device, and also having a sliding movement enabling one end thereof to be brought into engagement with the finger 1e ver, the said engaging end being beveled.

ssaaw 4. In a device of the character described, the combination of a finger lever, a sounding device, a fulcrum rod, a hammer operated by the linger lever and provided with a slot for the reception of the fulcrum red, the said hammer being thereby enabled to have a pivotal movement for being swung against the sounding device, and a sliding movement whereby it can be moved longitudinally into engagement with the finger lever.

5. In a device of the character described, the combination of a finger lever, a sounding device, a fulcrum rod, a hammer provided with a longitudinal slot through which the fulcrum rod passes, the said hammer being thereby enabled to have both a swinging and a sliding movement and being adapted to operate the sounding device, the free end of the hammer being engaged by the free end of the finger lever, and a spring operating to throw the hammer against the sounding device and to hold the hammer in position for engagement with the finger lever.

6. In a device of the character described, the combination of a sounding device, a hammer adapted to operate the sounding device and having both a sliding and a swinging movement the free end of the hammer being beveled, and a finger lever provided with a lateral projection engaging the free end oi the hammer and causing the hammer to have a sliding movement when brought into contact with the beveled surface.

7. in a device of the character described, the combination of a sounding device, a hammer for operating the sounding device, the said hammer having both a sliding and a swinging movement, a linger lover adapted to engage the free end of the hammer for operating the same, and a spring which serves the double function of causing the hammer to operate the sounding device and of holding the same normally in position to be engaged by the linger lever.

8. in a device of the character described, the combination of a pair of sounding devices, a pair of hammers for operating the sounding devices, a pair of linger levers for operating the before mentioned hammers, an intermediate finger lever, and a hammer engaging with the intermediate linger lever and provided with means for operating the two before mentioned hammers on opposite sides thereon.

Intestimony whereof ho aflixes his signature in presence of two witnesses.
