IMPROVEMENT IN TUMBLlNG-SHAFTS FOR CONNECTING POWER WITH MACHINERY.

Specification forming part of Lette-rs Patent N o. 82,447, dated September 22, 1868.

To all whom it may concern:

Be it known that I, DANIEL SNELL, of Springfield, in the county of Clarke and State of Ohio, have invented a new and useful Improvement in Tumbling-Shafts for Transmitting Power to Machinery by a rotary or revolving motion; and I do declare that the following is afull, clear, and exact description thereof', reference being had to the accompanying drawings, making a part of this specification, in which- Figure I is a perspective view of my inven-v tion. Fig. II is alongitudinal section thereof. Fig. 3 is a transverse section. Fig. 4is a perspective view of the bearing-collar C.'

Similar letters of reference indicate corresponding parts in the several figures.

The object of this invention is to allow the machine to which power is transmitted by a revolving tumbler-shaft to be removed farther from or nearer to such power, without the necessity of uncoupling the shaft for the purpose of introducing separate Vpieces to lengthen it or taking out any part of the same to shorten it, as in applying my invention to a wood-sawing machine, to obviate the necessity of using a truck or drag to bring the consecutive portions of the uncut log up to the saw, by the use of a revolving tumblingthe line of its length, one part so constructed as to admit of the other part sliding within or upon it in such line, for the purpose of rei moving the sawing-machine along thebody of the tree to saw it up into sections, without moving the power or uncouph'ng the ends of the shaft 5 or, in a thrashing-machine, for the purpose of allowing it to be removed farther in thrashing grain from the stack, thereby saving repeated handling of the sheaves by permitting the machine to be removed from the power to each stack by simply extending the shaft or contracting it, as'may be required, without the necessity of uncoupling it, the shaft being so constructed as to admit of such extension or contraction by the combination of' parts that slide within or upon each other, and yet so closely fitted in its sliding parts as to prevent any vibratory or undulatory movement, and to secure sufficient stiffness and resents a tumbling-shaft for transmitting`` power by a rotary or revolving motion, A

being the outer or guide part, and B the inner or sliding part, of the same. The parts e e represent the ordinary coupling ends or knuckle attachments.

Fig. II represents a longitudinal section of the shaft, showing the relative position of the several parts when the shaft is partly extended or lengthene'd. A represents the outerpart,with the guide or groove D, into which the rod B slides. b represents the block end or head portion of the rod B, and is clearly fitted to the groove or guide D, so that it remains at any point in position during the motion of the shaft, moving only in the direct line of the length of the shaft when it is required to be extended or contracted to alter the distance between the power and the.

machine. C represents a collar upon the end of the guide part A of the shaft, through which the rod part B passes, and which operates as one of the bearingpoints of the( saine. The collar C also acts as a cap to prevent the rod-shaft B from being entirely withdrawn and detached from the part A when the shaft is fully extended.

Fig. 3 represents a transverse section of the part A of the shaft, showing the groove or guide through the same.

I disclaim, in my invention, a groove or guide with a slide working in the same, in a pitman-rod or other connection, workingwitha lateral, reciprocating, undulatory, or oscillating motion, or when the same is attached by a pin, bolt, or other fastening, about which said motion is produced 5 but What I claim as new, and desire to secur by Letters Patent, is-

The combination of the collar C with its interior bearing c and the block end b of the rod-shaft B, sliding iu the groove D of the part A, for retaining the -shaft in position at any point in the line of its extension or confor transmitting ypower bye rotary or revolvtraction, as applied in a. tumbling-shaft, for ing motion this 17th day of August, A.D. transmission of power by a rotary or revolv- 1868.

ing motion, the whole constructed substantielly as described, as and for the purpose DANIEL SNELL specified. Witnesses Witness my hand to my application for a Enwnv F. HILL, patent on my improvement in tumbling-shafts B. C. CONVERSE.
