PIPE AND SHAFT COUPLING.

SPECIFICATION forming part of Letters Patent No. 462,894, dated November 10, 1891.

Application led April 22,1891. Serial No. 389,949. (No model.)

To @ZZ whom it may concern: recess l2, in whichis seated the annular flange Be it known that I, ROBERT DINSMORE, a 9 of the sleeve 8. The disk 10 is provided at citizen of the United States, residing at Wesintervals with key-hole slots 13, the large porton, in the county of Lewis and State of Vest tions of which are adapted to receive the heads 55 5 Virginia, have invented a new and useful of the pins or studs (5, and said studs are Pipe and Shaft Coupling, of which the followsomewhat shorter than the slots, so that they ing is a specification. do not extend completely through the same This invention relates to improvements in when entered therein.

However, by withdrawing the pin and employing a Wrench or other means, the disks may loe rotated so as to bring the heads of the studs to thelarge ends of the key-hole slots, and thus a separation may be effected.

It will be understood that this invention may loe advantageously employed in oouplin g shafts as Well as pipes.

Having described my invention, what I claim is- The combination, with the opposite pipe or shaft sections, of the disk 4, threaded on the same back of the end thereof and provided with threaded studs arranged in an annular series, at one side ot' one of which is formed the slot 16, the sleeve 8, having the flange 9 mounted upon the opposite pipe-section and and through the opening lo of the disk 4, substantially as specified.

In testimony that I claim the foregoing as lny own I have hereto affixed my signature in presence of two Witnesses.
