Patented Nov. 28, 1916.
Application filed April 22, 1915. Serial No. 23,073.
To all whom it may concern:
Be it known that I, CHARLES lVALns, a citizen of the United States, residing at New Haven county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a full, clear, and exact description.
My invention relates to calculating machines and has for its object to provide a machine which can be operated either by hand or by electric power, with means whereby the handle can be moved into and out of its normal operating position, and also with means whereby when the handle is in normal position the power circuit will be open.
It also has for its object to provide means for closing the power circuit when the handle is in its other position.
It also has for its object to provide a visual signal which shall indicate when the power circuit is open.
It also has for its object to provide means whereby the clutch-operating member is mechanically cut out'of action when the motor circuit is open.
It also has for its object to provide means for holding the handle onto its shaft.
The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which,
Figure 1 is a side elevation of a calculating machine embodying my invention. Fig. 2 is an enlarged view of the handle upon the end of the shaft which it operates, and in normal operating position, looking from the rear (Fig. 1). Fig. 3 is a side view of Fig. 2. Fig. 4 is a detail of an abutment plate carried by the shaft on which the handle is placed. Fig. 5 is a perspective view of'the inner end of the barrel of the handle.
Referring more particularly to the drawings, 1 is the near side frame of the operating mechanism of a calculating machine.
2 is the far side of the same.
3 is an electric motor mounted at the rear end of the machine, and having a shaft 1 eX- tending between the frames 1 and 2 to suitable connections (not shown) for actuating the crank shaft 5.
6 is an abutment plate secured to the shaft 5. This plate is provided with an abutment face 7 with which the handle engages.
8 is the handle having a hollow barrel the shaft 5.
9 which passes over the end of the shaft 5. It is provided on its inner end with jection 10 which, when the handle is in position, engages the lower face 7 of the abutment on the plate 6. With the parts in thisposition when the handle is pulled forward the plate 6 and shaft 5 are rotated in a counter clockwise direction. A handle is provided with a cutaway portion or recess 11 and with a groove or socket 12 in line with the inner part thereof. It is also provided with a recess 13 having a square face for purposes hereinafter set forth.
Mounted on the abutment is a spring pawl or detent consisting of a lever 14 carrying a detent Wheel 15 having a flange 16 which fits the groove or socket 12 in the handle barrel. A spring 17 is connected to the lever 1 1 and the abutment plate 6, drawing'the detent wheel 15 toward the shaft 5 and causing it to engage the groove or socket 12 in the handle barrel when the handle is in normal position. This holds the handle against endwise movement so that it cannot be removed while in normal position. I It also yields when the handle is thrown parting a shock to the mechanism through If, however, the handle is moved to the position shown in Fig. 1 the backward so as to prevent such backward throw from ima proflange 16 of the detent 15 rides up out of the socket or recess 12 whereupon the handle can be pulledoii'. In order to make it easy to put the handle on the recess or cutaway portion 11 is provided. This is opposite the detent 15 when the handle is in the position shown in Fig. 1 being angularly in front of the groove or socket 12. In order to put the handle on it is held in the position shown in Fig. 1 and slipped on the shaft 5. Thereafter, when it is moved to normal position (Figs. 2 and 3) the detent wheel 15 is caused to rise up until it reaches and falls into its socket 12, at which time the projection 10 engages the abutment 7. In order to prevent any undue strain from bending the detent plate 14 I provide a strain-resisting stud 18 which is secured to the lever 14: and passed through a slot 19 in the abutment plate 6. This stud is provided with an enlarged head which engages the inner surface ofthe abutment plate 6 and aids the lever 14 in resisting any strain due to an attempt to remove the handle while in normal position.
- In .order to control the motor circuit through the handle I provide a switch 20 from which lead the motor circuits 21, 22.
23 is the actuating lever of the'switch havarm 29 fixed on the rock shaft-29 at its 4 farther end. On the near end of this shaft 29 and in the same angular position on the shaft is also pivoted a rock arm 29 of same shape and'size as 29. To the arm 29 is connected the rod 30 whose forward end rests on the barrel 9 of the handle and rides thereon, its length being such that when the handle is in normal position the end of the rod falls into the recess 13. When the handle is moved backward to the' position shown in full lines in Fig. 1 the straight face of the notch forces the rod 30 and with it the rock arms 29 29 backward. This results in pulling the rod 27 to the position shown in Fig. "1 and moves the switch lever fas 23 and switch to on position. The rock arm 29 is provided with a retracting spring 31 the forward end of which is connected to the stationary frame of the -machine.
When the handle is moved upward to nor-- mal position this spring moves the rock arms 29 29' and rod 27 forward so as to throw the switch lever to ofi' position. When the handle is in normal position with the machine at rest the handle is in the position shown in dotted lines. In this position it is clearly visible and constitutes a visual signal or indicator showing that the motor circuit is open. When it is not in this position the fact that the motor circuit is closed can be perceived at a distance. This visual indicator reduces the liability of having the power circuit closed when the machine is not in use and inasmuch as motors in'this type of machine run continuously during the whole period when the machine is in use as a power driven machine, and until out out by a voluntary movement of the attendant, this visual indication results in considerable saving of expense and wearing of the parts.
32 is a plate on the keyboard the depression of which operatively connects the motor shaft to the operating mechanism of the machine. This connecting mechanism is .described in my pending application, Serial No. 874,975, filed December 1, 1914, and is actuated by the lever 41, so that when that lever is depressed the motor shaft drives the calculating mechanism. The plate 32 is provided with a depending arm the lower end of which is normally at a point just above the end 34 of a rod 35 connected to the rock arm 29. This end is provided with a cam the control of the-handle, the front end of the rod, thanks to the cam slot 36, moves to the lower position shown in dots in Fig. 1 so as to be out of the path of the arm 33 when. actuated by the plate 32. From this it results that the motor cannot be coupled by depressing the plate 32 if the handle of the machine is in normal position relative to its shaft 5, but can be if the handle is thrown back so as to throw the switch lever 23 to"on position. I
As will be evident, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.
What I claim is:
1. In a computing machine, the combination of a calculating mechanism, a motor and a handle for operating the same at different times, a switch controlling said motor and controlled by said handle so as to be in 011 position when said handle is in normal position.
