. .UNITED STATES PATENT OFFICE.
VFRANKLIN vSHEL'LEY, OF MUNCIE, INDIANA.
IMPRovEM ENT `IN HEAD- BLOCKS Fo'R SAW-MILLS.
Specificationforming part of Letters Patent No. 107,966, dated October 4, 1870.
To all whom t may concern.- i
y `Be it known that l, FRANKLIN W. SHELLEY,
of Muncie, in the county of Delaware and State of Indiana, have invented a new and Improved Head-Block for Saw-Mills; and Ido hereby i declare that thefollowing is a full, clear, and
are operated by a pair of sliding bars, so as to. impart the necessary intermittent forwardmotion to the block. ,1
A in the drawings represents `theheadblock. B is the frame on which the same-- slides. i y
` G C are twoparallel horizontal bars, pivoted at` their rear ends to bellcranks a a., which are connectedwith each other and with a lever, D,'by means of a jointed rod, b. By oscillating the lever `D the bars() C will be moved longitudinally backward and forward in opposite directions. The bars C C rest in the front and back ends of the frame B, and are in the same always guided parallel. y
To an ear, d, which projects from the under side of the head-block,iare`pivoted two jointed levers, E E,y whose lower members are perforated to embrace the bars G C, respectively.
Some springs, e, Iwhich proj ectdownward from [the head-block, hold the lower membersof the levers E forward in an, inclined position,
so that the upper back edges of their aper/ tures bite against the rods C. Whenever a rod, G', is moved forward it will be locked, together'withts levers E, to carry the headblock forward with it, while during the backward motion of each'bar C the same slides loose through the apertures of E without afi fecting the position of the head-block. Thus,
during every motion of the lever D the forward-moving bar C will feed the head-block forward.`
F is a sliding wedge suspended from a lever, G, which is pivoted to the head-block. When the lever G is swung down, the wedge will force the outer members of the levers E back, to cause them to release the bars C. The head-block can then be moved backward. The joint in each lever E allows the same to adjust themselves to inequalities of the bars C.
Having thus described my invention, I claim as new and desire to secure by Letters Patenty v 1. The reciprocating bars C C, operated by I the lever D, and combined with the perforated levers E E and head-block A, for feeding the latter, as set forth.
2. The levers E, combined with the springs e, and jointed, as described, for the purpose of communicating forward motion to the headblock from the reciprocating bars C, as set forth. i
3. The wedge .F and lever G, arranged on the head-block for the purpose of throwing the levers Eout of gear, as set forth.
FRANKLIN w. sHELLEY.
