HENRY A. House, or BRIDGEPORT, coNNEcTioUT.
Letters Patent No. 109,619, dated November 29, 1870.
IMPROVEMENT IN ADDI'NGAND SUBTRACTING-REGiSTERS.
The. B'cliednlo referred to in thany Lenten Patent and making part of the umn.
To all when: it may conce-rn'.-
lie it known that LHmmY A. Hoc-sn, of Bridgeport, in'the county of Fairfield and State of' Connecticut, have invented a. new and improved Calculating Device; and I do hereby declare that the following is a... full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in'which-- y Figure 1, plate 1, is a' view of the toothed disk and toothed rings, as' seen by removing the back ofthe case and the inside cam-disk.
Figure 2, plate 1, is adiametrical section through the device.v
Figure 3, plate 1, is a front view of the device complete.
Figure 4, plate 1,is a Aperspective view ot' the vibratingarm and its pawl,.`
Figure ,5, plate 2, is a view of the front sides of thc toothed disk audits toothed rings, showing the'manner of arranging numbers thereon.,
Figure 6, plate 2, is. a view of the eamfface ot"l thc cam-disk.
Figures 7 and 8, plate 2, are diametrical sections through the toothed rings.
Figure 9,1)late 2, is 'a dia-metlieal section through the setting-wheel.
' Figure l0, plate' 2, plate'.
Similar letters ot' reference indicate.corresponding parts in the several figures.V
'lhc object of my'inveution is toniinprove portable or pocket calcnlating-machines, so that t-heycan be more easily manipulated, and at'the same time made very simple, accurate, and complete.
is an edge view of the camj lhe ijnprovement which I have made on the pocket` register or calculator, which is 'composed pfl a' series ot' concentric rings, numbered with decimsvnnnning in regular order from 0't o t), consists in combining with the mechanism which will move the rings forward, a mechanism which will move them back again for com mencing the calculation with any given nninber orl figure- Ilhe following description will enable others skilled in the art to'undeistand luy-invention.
-'.ll.r ,-.\casc which contains thev toothed wheels, their cams and pawls, consists ol' two parts, A and B. p
'lhe part Alhas'a radial slot, 1'-, through it, for exposing to view the numbers which are marked on Vthe upper sides of the wheel G and concentric rings L J, as these numbers are successively moved opposite this opening. U v
A long slot,-s, isalso made through th; rim ot' the part A, for a pawlarm, 1),.-to vibrate.
Within this case a wheel, G, is centrally applied and fastened to the stem of a knob, G', by means ot' which this wheel can be'turned iieely, and between the wheel G and the rim ot' the caso are tw'o concentric rings, L J, .which can be turned about-the axis ot thewheel- G, as will be hereinafter explained.
. .The wheel Ghas teeth -m'ade radially on its back :riphery ot' the ring J, which, when this ring is turned as above stated, will engage with one or the other ot' the notches p made into theinner edge oithe ring L, andcause this ring 'to move around with the wheel G and ring J.
On the frontside of each one ot' the rings LJ are three dec-ilus, each deciin ruiming in rcg'nlarmimerica-l `ordcr from Oto 9, and on the front. side ofthe wheel Gunmbers are made, running in a eonccntriccirclc, from) to 29. v v
There are thirty characters on eachone ofthe rings, and a corresponding number on tho wheel G,so arrangedthat, when all the numbers on the rings representing' the same value arc opposite cach other, these rings will be engaged with each other by the paw] a5, and when the cipher on the wheel G is opposite either one of' the corresponding marks on the ring'J, the pawl will engage the latter with the former; consequently, by turning vthe wheel (l in the direction indicated by the arrow in iig. 1, three ci pliers can be brought in line with each other opposite the opening e', through the front of the case.
There are thirty ratchet-teeth ou.the back ot' each one eti-the ringsL J, sg spaced that, when the rings are adjusted, as shown inftig. 1 their teeth will bein lines coinciding with the teeth on the back of wheel G.
The teeth on the ring L are acted upon by a spring-` pawl, f, cna vibrating arm, D.
rlhe teeth on ltire .ring J are acted upon by a hooked springpawl, o, and the teeth on wheel G are acted on by a hooked spring-paw'l, o'. l y
lhe springs pp', which are applied in groove-sin the rings, press against a disk,"C, and keep the rings in close contact'with the t'ront plate of the case.
rlhe pawl-arin fl) vibrates freely about a shorthuh, which is centrally formed on the back of the disk O, and oli-thc exposed end of this arnl a knob, e,- is secured, having a pointer, c', formed on it, which latter /is directed toward the center of the case` and is`in' tended to point atiigures "which are lnarled'on the front of tho case ou opposite sides of the slot i, as shown in tig. 3. These figures run fronrO to 9.
By vibrating the a1-m1) the ring Lis moved by pawl.
f engaging with the teeth on this ring.
'lhe ring J- is moved a distance equal tothe spaces I between its numbers or characters, bymeans of the hooked-pawl o, which, at certain times, is pressed up- The instrument is then held in the leftl hond;
on by 'one of' threecnms, c, on the face oi' disk C; and
the wheel G is in like manner moved by the pztwl 0','
:is the latter posses by one of said cams c."
The arm D is connected to the hub of the disk C by means of a screw, el.
The disk C is secured fast to the rim of the case, and the buck plate B of the case isfsecuredto the disk in any suitable manner.
' Screw a may be used to secure the buck B to the 'en-se.
Before using,r the instrument to czivleulnte, the knob G is turned until the ciphcrs on the wheel G, the ring J, and ring L are brought in line opposite the slot fi. with the fingers of the left hand or right handthe arm D is vibratcd, and its pointer c moved opposite' the reiuircd number marked cn'the time of the onse, each time moving the arm back ns far as it will go.
The first ring L will indicate tens, and theV third wlicel indicates hundreds und thousands.
By means of' the wheel G, and its external knob Gr', the rings ezin be quickly turned buck to the ciphers, or to anyrequired numbers.
Having described my invention,
What -I claim as new, and desire to secure by Letters Patent, is
1. The combination, with one or more concentric rings, which nre numbered, toothed, und notched, and' scribed.
