OSCAR GRIMWOOD, OF OWENSVILLE, INDIANA.

LOADER AND UNLOADER ATTACHMENT.

To all whom it may concern:

Be it known that I, OSCAR GniMWooD, a citizen of the United States, residing at Owensville, in the county of Gibson and tate of Indiana, have invented a new and useful Loader and Unloader Attachment; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as "will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improved means for loading and un oading ears, vehicles and the like.

'I he present invention is herein shown applied to a car.

In the drawings, Figure 1 is a side elevation of my device showing the same applied to a car door. Fig. 2 is a plan vie of the same. Fig. 3 is a side elevation sho mg the device in the act of being applied to the door nay of a car. Fig. A is a longitudinal sectional View of the same.

Referring to the drawings, 1 and 2 designate the main body members of my invention. The member 2 is provided with a longitudinal recess 5 in which is adjustably inserted member 6. The member 6 is provided with a series of perforations 7 which are adapted to register with perforations 8 of the member 2. A pin 9 is provided which engages the aforesaid perforations as clearly shot-in in the drawings. T he pin 9 holds the

members

2 and 6 at the desired adjustments. 'I he end of the pin 9 is provided with a pivoted member 10 which is designed to lock said pin against accidental displacement. slot 11 is formed in the

members

2 and 6 through which a pin 12 is inserted, on the upper end of nieh a U-shaped frame 18 pivotally mounted, having a roller 14 mounted in the upper POTtiOIi'tliQTGOi'. it will be seen that the pm. 12 can be mo ed to any position within the slot 1 1 as convenience may require.

The members 1 and 6 are provided with metallic teeth or pins 4 adapted to be inserted in the sides oi the car door.

The members of this device may be made of wood, metal or other suitable material.

In practice, the device is placed in the car door in the position shown in Fig. 3, when the members 1 and 2 are pressed downward until the device assumes the position shown in Fig. 1. The members 1 and 2 are hinged Specification of Letters Patent.

The operation of the device is as follows: One end of the lumber is placed upon the roller 14 whereby the said lumber can be easily moved in or out of said car.

It will be seen that my invention is simple, efficient and durable and that the same can be readily applied to the door of a car or large vehicle in a very simple and convenient manner.
