ATTACm-NT non Annme-mcmnns.
Specification of Letters Patent.
Patented June '30, 1908.
Application filed May 23,, 1907. Serial No. 375,880.
Be it known that I, Cant L. BECKER, a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented certain new and useful Improvements in Attachments for Adding-Machines, of which the following is a specification, reference being had therein to t e accompanying drawing,
-My invention relates to adding machines and especially tothat type ofadding machines which use a printing lever for bringing the digit wheels into recording position and for printing the total on the recording tape. Heretofore these printing levers have been operated by hand, and where the operator had to use one hand for turnin checks'or other papers and the other hand or pressing the digit buttons, it was very inconvenient to operate the rinting lever and necessarily caused consi erable loss of time in a days work. It is the object of my invention to obviate these difficulties and to provide a simple and inexpensive device which may be removably secured to the printing lever and supporting frame of any standard machine, whereby both hands may be used in turning papers and in punching the buttons and the printing lever may be operated Without loss of time.
Briefly stated, the invention consists in providing a detachable bell crank lever which may be removably secured u on the shaft of and tothe printing lever an which may be controlled by a foot lever pivoted removably on the frame. 4 A My invention is illustrated in the accompanying drawings, in which 7 Fi ure 1 is a side elevation of a supportin stan with an adding machine mounte thereon and my attachment applied thereto, and, Fig. 2 is a detail perspective of the bell crank leverand its operating rod. v
Referring to the drawings, 1 represents an adding -machine which, in this mstance, is seated upon a base 2 carried on the usual supporting frame which comprises legs 3 connected together by crossing tie bars 4. The adding machine is shown to be of the usual Burroughs type with its printing shaft 5 projecting out from the side thereof and having secured to it the printing lever 6. The frame comprising the legs 3 and the tie rods 4 is of the common type and is provided with a projecting stud 7 upon which is pivoted the cot lever 8 in this instance slotted at 9, so as to removably engage the pivot post. This. lever extends outwardly toward the front of the machine and is provided at its forward endwith a foot piece 10 by which it may be operated. Intermediate the pivot stud 7 and the foot piece 10, and nearly adjacent the latter, the lever 8 is provided with an aperture through which the lower hooked end of a connecting link 11 is passed, the upper end thereof being secured to a laterally projecting lug 12 on the bell crank lever 13 in a similar manner. This bell crank lever 13 comprises a triangular iece of sheet metal stamped out as a who e from a single sheet of material and having one of its corners bent into an a ertured lug 12 to receive the hooked end of the connectin link 11. Upon the side opposite from the ug 11 two projecting ears 14 and 15 are bent over so as to engage the printing lever 6 and below these ears the bell crank lever isiiotched'or perforated at 16 so as to enga e the shaft 5. The printin levers of all of t ese machines are returne to normal by a s ring within the casing (not shown) and the 1 lustration indicates the operating device in normal position with the lever retracted When it is desired to throw the lever to its forward position to accomplish the function of that member it is only-necessary to depress the lever 8 by pressure u on the foot piece 10 and thereby, throug the connectmg link .11, operating tiiefbell crank lever to revolve the printing s a t.
I have shown the connecting link between the bell crank lever 13 and the foot lever 8 as a single integral rod with hooked ends to en gage the hole in the foot lever 8- and the aperture in the lug 12 of the bell crank lever 13, but in practice I preferably use a two part rod joined together by a turn-buckle by which the length of the rod may be adjusted. This enables me to secure the pro er throw or length of travelfor the printing ever. 1
In the ordinary supporting frame there is no stud 7 upon which to pivot the foot lever. I therefore pivot this lever directly upon the connecting bar which runs between the lower end of the legs.
From the foregoing descri tion it is thought that the operation nee not be further described and that it will be well .understood by those versed in the art. It will also be seen that while I have described and illustrated a splecific and simple form with which way limited to the disclosure-made as many In a device of theclass described, a sup porting frame, a tie rod thereon, an adding machine mounted on said support, a shaft projecting therefrom, a handle on said shaft at right angles thereto, a rigid foot lever having an opening to engage said tie rod at the rear of the frame, and a projecting front end, a triangular member punched from sheet metal bent over at one point and, perforated for the reception of the connecting rod, provided with a semi-circular hearing at its apex adapted to fit upon this shaft, and provided with a pair of projections or lugs on the edge opposite the bent-over point, sald lugs being returned upon themselves so as to form hooks to engage the aforesaid-handle, and a rigid metal tie rod'passing through a transverse opening in the foot lever at its lower end, at its upper end provided with a hook en aging an o ening in the bent-over point of t 16 triangu ar member, all of said parts forming a unitary whole adapted for instant and ready removal to and from the adding machine without the aid of tools, substantially as described. p
In testimony whereof I aflix my signature in presence of two Witnesses.
