BASKET-BALL BACK STOP.
Application filed July 28, 192-3.
To (ZZZ en/mm it may concern:
Be it known that I, ALBERT E. THORNLEY,
a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in- Basket-Ball Back Stops, of which the following is a specification.
This invention relates to certain new and useful improvements in basket ball back stops such as are commonly employed in gymnasiums and the primary object of the invention is to provide a device of this kind which is not only portable but which also is collapsible to permit of movement and storage beneath the gallery or other convenient and suitable place in the gymnasium.
A further object of the invention is to provide a back stop which is capable of being easily and quickly collapsed as well as extended into operative position, and which also eliminates the use of screws, gears, cranks and the like in collapsing and extension of the structure.
A still further object of the invention is to provide a collapsible back stop which utilizes the inclined-plane principle and one which also is of simple, economical and compact assemblage, embodying a minimum of no parts.
Other and still further objects will later appear and be manifested in the course of the following description.
In the drawings Figure 1, is a perspective invention showing the parts position.
Figure 2, is a similar view parts in collapsed position, and
Figure 3, is a detail view of the latch.
In proceeding in accordance with the present invention a base frame is employed which includes side rails 1, having brackets 2 secured to the ends thereof, the brackets 2 being connected by end rods 3, the whole forming a horizontal structure. The brackets 2 afford mountings for casters 4 so as to enable the entire device to be easily moved from one place to another.
A pair of vertical front standards or posts 5 are carried by the horizontal portion of the base frame and are braced by a pair of rearwardly and downwardly inclined trackforming bars 6. The posts 5 are braced and connected by a cross-rod 7, while the view of the in extended showing the Serial N0. GMAIB.
bars 6 are similarly braced andconnected by a cross-rod 8.
The back stop proper or board 9 has brackets 10 connected to a cross-rod 11 secured to the upper ends of the inclined bars 12 of a sliding frame. The bars 12 slide on the upper faces of the bars 6 of the base frame and are connected and braced by cross-rods 13 and 14 secured at their ends to the bars 12.
An upper and a lower pair of guides 15 and 16 are secured to the inclined bars 6 of the base frame and are provided with antifriction rollers 17 which permit of easy sliding of the sliding frame on the base frame.
The inclined bars 6 of the base frame are further provided with pulleys 18 over which wire cables or ropes 19 are trained, the cables having weights 20 on one end and having their opposite ends connected to the crossrod 14 of the sliding frame. The cross-rod 11, at the upper end of the sliding frame is connected to a downwardly inclined bar 21 secured to the board 9.
For the purpose of holding the sliding frame and the back stop proper in either collapsed or extended position, a pair of latches 22, shown in detail in Figure 3 are employed the latches embodying housings 23 with sliding bars 24 having handles 25, the bars engaging in keepers 26 carried by the bars 6 of the base frame.
Fro-m the foregoing it will be apparent that in order to extend or collapse the structure it is merely necessary to release the latches and to then slide the movable frame along the tracks 6, which may be easily effected by the operator grasping the crossrod 14, the movement of the sliding frame being along an inclined plane which enables same to be easily moved and with the expenditure of comparatively slight force or exertion.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a basket ball back stop, a base frame lnving a horizontal portion provided with casters and having vertical front posts and inclined rear bars connected to the vertical posts and to the horizontal portion, a back stop board, a sliding frame carrying said board and including inclined bars slidable on the inclined bars of the base frame,
guides carried by the inclined bars of the base frame and engaging the inclined bars of the sliding frame, pulleys carried by the inclined bars of the base frame, cables having weights connected to the inclined bars of the sliding frame and trained over the pulleys, and means to latch the sliding frame vin extended and collapsed positions.
2. In a basket ball back stop, a base frame having inclined guides, a movable frame having a back stop board and having inclined parts engaging said inclined guides, and Weighted cables connected to the movable frame and to the base frame to counterbalance the movable frame.
3. In a basket ball back stop, a base frame having inclined guides, a movable frame having a back st-op board and having inclined parts engaging said inclined guides,
- and counterbalancing means for the sliding iclined parts engaging said inclined guides,
counter-balancing means for thesliding frame, and means to latch the sliding frame in both extended and collapsed positions.
5. In a basket ball back stop, a portable base frame having inclined guides, and a.
movable frame having a back stop board and slidable on said guides.
6. In a basket ball back stop, a portable base frame having inclined guides, a frame having a back stop board slidable on the guides, and counter-balancing means for the slidable frame. 7 V
7. In a basket ballback stop, a portable base frame, a frame having a back stop board slidably carried by the base frame, and counterbalancing means for the'sliding frame.
In testimony whereof I have signed my name to this specification in the presence 0 two subscribing Witnesses.
