BEN SCHMIDT, 0F BIGSTONE CITY, SOUTH DAKOTA.

POWER-TRANSMISSION DEVICE.

Specification of Letters Patent.

Patented July 23, 1918.

Application filed September 25, 1917. Serial No. 193,154.

To all whom it may concern:

Be it known that 1, BEN SCHMI T, a citizen of the United States, residing at Bigstone City, in the county of Grant and State of South Dakota, have invented new and useful Improvements in Power-Transmission Devices, of which the following is a specification.

The invention is an attachment to be applied to motor vehicles and seeks to provide, as its principal object, a device to permit the power of the engine of such a vehicle to be utilized for purposes other than the driving of the machine.

Another object is to provide such a device which may be attached to various makes of motor vehicles without requiring radical modifications to be made.

Still another object is the provision of a device which will be enabled to accomplish its purpose without detracting from the general appearance of the vehicle to which it is attached.

Still another object is to provide a device of this kind which is simple in constriiction', which may be easily and cheaply made and which will effectively accomplish the purpose for which it is designed.

Other and further objects will appear in the detailed description of the device which follows.

In illustrating and describing the inven tion, a particular design has been adhered to, to which, however, the invention is to be in no wa restricted. The right is claimed to ma c any changes or alterations suggested by the demands of practice, pro vided such changes or alterations are comprehended in spirit by the subjoined claims.

In the accompanying drawings z Figure 1 is a view partly in section and partly in elevation, showing the forward end of a conventional form of auto-vehicle with the invention applied thereto.

Fig.2 is a plan view of the structure shown in Fig. 1. v

Fig. 3 is a collective view, partly in section, showing the ends of connectin shafts which form a part of the device.

Referring to the drawings, there is shown the front end of the conventional form of automobile, in which front end the engine 1 is mounted with its shaft 2 projecting forwardly therefrom, this shaft being provided at its end with a well'known clutch member 3. Engaging the clutch member 3 there is a mating clutch member 1 and this latter member isattached to the rear end of the shaft 5. This shaft 5 is that to which the starting crank would be attached, were not the present invention applied to this particular machine; and the shaft is equipped at its forward end with an integral extension 6 which is square in cross section and whose diagonal width is less than the diameter of the shaft. The shaft is provided with a. mnventional bearing 7 in the vehicle frame below the radiator S and is capable of longitudinal movement as well as rotary movement in this hea ring, so that, when the shaft 5 is used for starting the engine, it may move forward disconnecting the clutch members i and 8 after the engine has been started. This longitudinal movement of the shaft 5 is precluded, however, when the present device is attached, in order that the shaft 5 may act as a connecting link between the engine and the device.

The forward downwardly curved ends 9 of the vehicle tt'ran'le to which the forward ends of the springs 10 connect are intended to be utilized as a means for supporting the forward end of the device. An angle iron 11 is provided of slightly greater length than the distance between the outsides of the two forward ends 9 of the vehicle frame. This angle iron l'lhas attached to one of its flanges near the ends thereof and by means of suitable rivets 12 the curved plates 13 which extend at right angles to the length of the angle iron but which are curved to correspond to the curved ends 9 of the frame. These plates 13 are off-set with respect to the flange of the angle iron 11 to which they are attached, so that this flange may lie in a plane parallel with the plane of the shaft 5. The plates 13 are secured in position on the curved ends 9 of the frame by means of U-bolts 14 which straddle the curved ends 9 of the frame and receive over their free ends the plates 15 which lie against the upper face of the plates 13, nuts 16 being screwed onto the threaded ends of the U-bolts 14 and holding the plates 15 in place. The plates 13 and the angle iron 11 which they support are thus securely attached to the forward curved ends 9 of the vehicle frame.

At the longitudinal center of the angle plate 11 and on the upper face thereof, there is mounted a suitable bearing 17. A

shaft 18 is journaled in this hearing near its forward end and carries a collar 19' which is designed to abut this bearing on i the inner face, a set screw 20 being provided for securing the collar in place on the shaft.

Just in front of the radiator 8 and also connected between the forward ends ofthe vehicle frame, there is, asecond. angle-iron 21, so positioned that its under face will lie parallel with the shafts 5', and 18.. This position brings one flange of this angle iron into a horizontal plane and. the other flange 1 into a vertical plane, the vertical flange hav- 1 of the shaft 18 is journaled in this second hearing and this; shaft is provided on this rear end with a broached hole 25, square incross section and of proper dimensions to receive the square shaped extension 6 of the shaft 5. I

The shaft 18 is, equipped at its forward end on that part which projects fromcthe bearing 17 with pulleys '26and 27, the pulley 27 being fixed to the shaft and the pulley 26 being provided with a flange and loosely mounted on the shaft. 7

From the drawings and the foregoing description,'it will be easily understood how the device is attached and the embodiment disclosed shows how the device may be utilized without removing the shaft which receives the starting crank. -With the clutch members 3 and 4 in engagement, the shafts 5 and 18 coupled by means of the square extension 6 and the square hole25 and the collar 19 positioned against the inner face of the bearing 17, the longitudinal movement of the shafts5 and 18 is precluded and the rotary movement of the engine isthus transmitted to the pulley 27 from which a belt may be carried to any device which it is desired to operate by the engine. The loose pulley 28 provides means for stopping as desired, without stopping the engine, any

,flopies of thiapatent'may be obtained for Although the invention is illustrated as being applied without doing away with the starting-crank shaft, it is obvious" that this shaft (represented by shaft 5) may be removed, and the main shaft of the device (represented byshaft 18); may be extended through the bearing previously occupiedby the starting-crank shaft and receive on. its end a coupling 4 adapted to engage the coupling 3. If this arrangement is employed the angle iron 21 and the bearing which it supports will be unnecessary, since their place will be taken by the bearing previously occupied by the starting-crank shaft. The manner in which the angle iron 11 is supported and connected to the curved ends 9 of the vehicle frame enables the position of this angle iron and the bearing which it supports to be varied in position so as to bring this hearing in alinement with the bearing of the starting-crank shaft. Since the plates 13 are held frictionally on the curved ends 9 of the vehicle frame by the U-bolts 14, their positions, on these curved ends may be varied, so asto, raise or lower the angle iron 11 with its bearing 17 thus effecting; the alinement desired.

What is claimed'isz- In a device of the kind set forth, a shaft, a forward bearing therefor, a support for said bearing consisting of an angle iron for transverse positioning across the forward downwardly curved :ends of an auto vehicle frame, curved plates secured to the angle iron near the ends thereof and at right angles thereto, the plates corresponding to the curvature of the curved ends of the vehicle frame, U-bolts straddling the plates and the curved ends of the frame whereby the supportas awhole is secured frictionally to the frame to enable its positioning to aline the shaft with the vehicle engine shaft, means for coupling the shaft to the vehicle engine shaft, and tight and loose pulleys carried by the shaft.

In testimony whereof I affix my signature.

BEN SCHMIDT.
