My invention relates to the means whereby the crank handle, or otherypowerele ment, is connected 4 with I the calculating mechanism-to actuate the latter after :the same has been preliminarily set, and the object of the invention .is. to provide such a, connectionas willvbe simple in construction and in operation-for the purpose of prevent ing any undue strainfrom beingkimposedc upon the calculating mechanism. Accord ing to my invention, if the calculatin mechanism does. not' yield to a norma amount of force, a portion of my connecting means will move. with the handle and leave the calculating mechanism umn ured.
And my inventionconsists in'the parts and combinations thereof, for such purposes, hereinafter set forth and claimed.
With such objects inview'as well as other advantages WhlGll may the incident to the use of the improvements, the invention consists in the parts andicombinationsthereof hereinafter set forth and claimed, with the understanding that the several necessary elements constituting the same may be varied in proportions and arrangement without departing from the nature and scope of theinvention.
In order to make the invention more clearly understood there are .shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, intheir useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration. In said drawingsf p I Fig. 1 is a side elevation of the actuating and power-controlling mechanism of a calculating machine, showing the embodiment of my invention in its preferred form, the parts being in normal position before the actuation of the same. i a J Fig; 2'is a plan view of the same.

from the others. U
Referring to the drawings, 1 is 'a portion of the frame of anadding machine, and 2 the main power shaft mounted in suitable bearings (not shown) on the framefto turn forwardand backward therein in a known manner forthe o eration of the machine. 3. is a crankv hand e havingahub 4, which fits on the shaft 2, but-may turn relative to the shaft. The shaft is. formed with a roove5 intov which fits a spring-pressed all or other keeper enclosed in a housing 6 fixed on the handle, this arrangement leaving the handle free for turning on the shaft but holding it from endwise displacement.
her, for, actuating the shaft.
7 isthe full stroke torfixed on the shaft 2, with which sector cooperate in a known manner pawl devicesshown at 8 to compel the full stroke to be made after it has begun. 9 is adash pot or governor fixed to the machine frame and having. its rotaryor other iston or mo able element connected by a ink 10 with the sector to retard the return or backward movement of the mechanism. llis a stud fixed on the sector with which is connected an-arm 12 mounted loosely on the shaft'2, This connection is preferably efor other driving appliance, a known man-f to the arm '12 and bears against the stud 11. -15 is a spring which is connected at one end with the hub of thearm l2 and at its other end with the end of =the paw1 and causes the 100 the arm 12 moves forward the sector and 105 shaft 2-make a corresponding partial rotation.
16 is'a link of triangular shape, or having three pivotal points, which is pivoted a r one of said points 17 to the arm 12, said pivot up For said handlemaybe substituted a motor I fected by a pawl 13 which is pivotedfat 14 being a projecting stud. Another of said pivotal points 18 is connected by it link 19 with the main retracting spring 20, the other end of said sprin being attached at 21 to the dash pot or ot er fixed part of the machine frame. The third pivotal point 22 of the link 16 is connected by a link 23 with a finger 24. This finger has a hub-portion 25 which fits loosely around the shaft 2 and is formed with radial a ertures 26 (Fig. 7 in which fit lu s 27 ig. 2) formed on the hub of the ban le. Consequently the handle and finger turn together, either with the shaft 2, or relative thereto when the sector resists turning. As shown in Fig. 1 the'han- -dle isin its rearmost or normal position of 1, if the andle be pulled v means of the link rest, the turning of the handle and finger being arrested by the pivot stud 17 against which the hook or end 28 of the finger is engaged. Various means may beuse to effect this stoppa e Without departure from my invention. 11 this position all of the parts, includi'ngthe link system, are stabilized under the stress of the main retracting spring 20, because turning in any direction woul increase the stress in the sring. The sector is provided with an in ependent means to arrest its backward movement consisting of the stud 29 fixed in the machine frame, in order that the sector and shaft may come to normal position organize the adding mechanism with which the shaft is connected.
-The stabilization of the parts at rest as above described results from their combination and the arrangement of their various centers of motion or pivots, as shown, but it will be understood that my invention extends to various equivalent combinations.
Startin from the position shown in Fig. forward, and the sector be not held by any catch in the addin mechanism or otherwise, the finger 24 wi l accom any the handle and pul upward by lin 23 on a line near the main pivot 17 of the triangular link, so that it is easier for the pivot 17 and the arm 12 to follow the finger and handle than for the trimgular link 16 to turn on said pivoqsuch turning being resisted b the spring which tends to turn the link 16 own anti-clockwise rather than up. In this movement the stud 17 remains in contact with the finger, and the arm 12 carries forward with it the stud 11, sector 7 and shaft 2. (Fig. 10.)
But if the sector be held stationary, by any accident, obstruction, or imperfection, the finger 24 will leave the'stud 17 and by 23 will turn the link 16 u ward and backward (to the right in Fig. 1 the link s stem will or can 0 en out to the sition s own in Fig. 3, and the bandle will perform its inefiective" movement without injury to the adding mechanism.
When the handle is released or moved backwhich is conveniently ble under t accurately, and not dis-- ward the spring 20 will restore the parts to the position shown in Fig. 1. The handle need not be turned to the full extent shown in Fig. 3, which shows tie. full capacity of the mechanism in that respect.
In order to properly control the link 19 in this movement and keep it between the pivots 17 and 22 I arrange a stop for it, a lateral lug 30 formed on the link 16 and engaging with the rear edge of the link 19 (Figs, 2 and 3). When the sector moves with the handle this stop will disengage from the link.
I have thus what may be best described as a folding s stem .of links which is extensilie pull of the handle, in case of obstruction to the operation of the adding mechanism, and is contractible under the pull of the main spring 20, the links which ave such folding function being in this instance the links 16 and 23.
31, 32 are stops on the lower part of the finger 24 adapted to engage respectively with the front or rear side of a stud 33 which is fixed to the machine frame, whereby the forward and backward movements of the handle are limited.
In the ordinary operation of the machine, when the sector turns, the spring 20 will not be extended so much as is shown in Fig. 3.
It will be apparent that the mechanism which connects the handle with the shaft is such that the same de ree of movement of the handle gives to the main spring two different extensions-a. lesser extension when the shaft turns with the handle and greater extension when the handle turns and the shaft remains stationary; and from this it results that the mechanism will operate in the manner which retiuires the less extension of the spring un ess some obstruction necessitates the greater extension.
It may also to be connected are the handle and the shaft. I use the'sector as a convenient agency in the connection but the connection could be made without the use of the sector for that purpose.
