I calname-MACHINE.
Specification. of Letters Patent.
` Patented April 9, 1907'.`
pullman and seminarie, 190e. sash rescates.
To all whom, it may concern,-n
Be it known that we, JOHN F. KINsTLn and JOHN M. PEox, citizens of the United States, residing at Warren, in the countyof Huntington and State of Indiana, have invented a new and useful Grinding-Machine,
is a specification.
This invention ates to machines for grinding valves; and its object is to provide a simple and inexpensive machine of this character which can be readily placed in enga ement with a valve for the purpose of rotating the same 4to grind it. Y
Another object is to provide a machine b e to meet various conditions.`
V ith the above and other objects in view the invention consists of justable standard to which a bar is pivotal] connected, said bar carrying a rotatable shaft and means for operating it. The yokel is adconnected to the bar, and the shaft is movab e therewith and provided with means for transmitting rotary motion to a chuck in which a valve-engaging'tool is adapted to be fastened. y
The invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims. the accompanying drawings is shown the preferred form of the invention.
in elevation and part In said drawings, Fivure 1 is a view, partly Iy in section, showing the apparatus in position for rinding a valve. Fig. 2 1s a detail View of thease and standar and Fig. 3 is a similar view of the valveengaging tool.
eferring to the figures by characters of reference,` 1 is a. longitudinally-slotted base having a tubular standard 2 integral therewith. A rod 3 is slidably mounted Within this standard and is adapted to be held in adjusted position by means of a set-screw 4 or 1n any other suitable manner. A head 5 is formed at the outer end of the rod 3 and is pivoted within one end of a bar 6 and .upon a set-screw 7, by means of which the bar may be held at any desired angle to the rod 3. ArmsSextend laterallyfrom the bar and constitute bearings for a guide-shaft 9, having a crank-ami 10 at one end and a gear 11 at its other end. This gear meshes with a gear 12, which. is feathered upon a shaft 13. This shaft 1s slidably mounted within the bar 6 and extends through a tubular arm 14, proa longitudinally-adupon the valve and valve-seat.
jecting laterally from the'bar. .A-sleeve 15t 1s slidably mounted on the arm 14 and is adapted to be locked in adjusted position` by means of a set-screw 16 or other suitable device. This sleeve extends laterally from a yoke 17, in which the shaft 13 is journaled,
at one end of shaft 20 and is adapted to ref ceive a tool 22, which j in by means of a set-screw 23 or in an `other preferred manner. A spring 24'is disposed upon the shaft 20vand bears at opposite ends against the yoke and the chuck, respectively, so that a longitudinal ressure may be exerted thereby upon the c luck during the operation of the machine. The free end of the tool 22 is flattened to produce an ed e 25, adapted to be inserted into a slot26, 4ormed in the valve 27 to 'be ground.
In using the machine herein described' base 1 is clamped in position in any preferred manner, as by placing a bolt within the slot of said base. The valve 27 is placed Within the valve-seat and the machine is adjusted so as to permit the insertion of the tool 22 into the valve-Casinor with .its edge 25 seated in the groove 26. n adjusting the machine to this position the spring 24 is partly compressed, so as to exert a constant longitudinal pressure upon the chuck. A vertical adjustment of thelmachine is permitted'by the may be fastened theremanner of assembling the rod 3 of the standard 2, an angular adjustment is permitted by reason of the pivotal connection between the rod 3 and bar 6, and a lateral adjustment is permitted by the arm 14 and sleeve 15. In view of these adjustments the tool 22 can be easily moved in various directions from the base l-in order that it may be brought into proper position upon a valve. After. the parts have been placed in the manner described the crank-arnilO is rotated and motion is transmitted through the various gears, shaft 20, and chuck 21, and the valve is therefore caused to rotate upon its seat, and a'smooth fit will therefore be produced. As the shaft 2O is movable longitudinally through the gear 19, the spring 24 will exert a constant pressure against the valve, so as to automatically take up the wear roduced by t le grind-l ing operation.
The machine is very simple and inexpensive in construction, and by disconnecting the adjustable portions thereof .it can be placed in ai compact bundle convenient for storage or transportation.
It will of course be understood that when desirable the crank 10' vmay be attached directly to the shaft 13 instead of to the shaft 9.
The preferred form of the invention has been set forth in the foregoing description; but We do not limit ourselves thereto, aswe are aware that oertainmodications may be made therein Without departing from the spirit or sacrificing the advantages thereof, and We therefore reserve the right to make such changesas fairly fall Within the scope of the claims.
What is claimed is- 1; In a machine of the character described the combination with a bar and supporting means therefor, said bar being pivotally mounted and adjustable longitudinally; of a yoke adjustably connected to the bar, a rotatable tool-engaging device carried by the yoke, actuating mechanism upon the bar, and means for transmitting motion from said mechanism .to the tool-engaging device.
2. In a machine of the character described 4 mounted Within the bar, means upon the bar.V
for rotating the shaft,v a yoke adjustablylconnected to the bar and constituting a hearing for the shaft, a shaft rotatablyr and slidably mounted Within the yoke, means'for transmittiiig rotary motion from one shaft tol the other, and a spring-pressed tool-engaging 'device upon the last-mentioned shaft.4 In testimony that We claim Athe foregoing as our oWn We have hereto afiiXedlour signatures in the presence of two Witnesses. 1
