CLINKER EXTRACTOR Filed May 9, 1955 Snnentor Richafd P C'OIWI'II Patented Nov. 3, 1936 UNITED STATES P TENT OFFICE 2,059,439 CLINKER. EXTRAGTOR" Richard P. Colwill,10maha,Nebr. Application May 9, 1935, Serial No. 20,597
Claims.
This invention relates to a clinker extractor, and has for its objects to provide a device which will be convenient in use for gripping and removing cinders from a furnace, will be durable, and will consist of few and simple parts which may be conveniently assembled and may be manufactured at a limited cost.
The invention relates to an improvement in that class of clinker extractors which employ longitudinally reciprocating clamping-bars, and in the present instance the improvement consists in the use of few parts of such construction and arrangement that friction of the slidable extractor will be reduced to a minimum and lateral swinging movements thereof avoided.
With the foregoing objects in view the invention presents a new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawing, wherein,-
Fig. 1 is a side view in longitudinal section of the front end-portion of a clinker extractor embodying the invention, and Fig. 2 is a similar view of the rear end-portion thereof.
Fig. 3 is a view in transverse section through the tubular holder, semicircular slidable operating-bar and semicircular bearing-block on lines 3-3 of Fig. 1 and Fig. 2. Fig. 4 is a top plan view of a combined bearing-block and prong.
Referring now to the drawing for a more particular description, in which like characters indicate like or similar parts, the clinker extractor consists, of a rectilinear, tubular holder 5 having a diameter convenient to be controlled by a hand of an operator.
Numeral 6 indicates a bearing-block, semicircular in cross-section, disposed in the front end of the tubular holder, said block being provided with apertures l and having a forwardly projecting, downwardly inclined, rectilinear prong 8 with a convergent sharp terminal 9 of fork-shape, each tine of the fork preferably having a fiat bottom ll) shown in Fig. 1 of the drawing.
Numeral ll indicates a second bearing-block disposed in the rear end of the tubular holder and provided with apertures l2, and at I 3 are indicated rivets or similar keepers, each disposed in an aperture of a bearing-block and traversing the wall of the tubular holder, and having a head countersunk in the fiat surface of a bearingblock, the spacing of said blocks providing a recess or chamber in said holder.
Numeral l4 indicates an operating-bar semicircular in cross-section disposed in the upper half of the tubular holder with its fiat surface engaging the fiat sides of the bearing-blocks 6 and II, and adapted to be reciprocated longitudinally by use of the handle I5, the bar l4 being bent to an obtuse angle to provide said handle.
The forward end-portion of the operating-bar movements, lateral movements will be prevented,
thehook I6 being of such proportions that its terminal ll will be disposed in a plane below or outwardly of the forked end of the rectilinear prong 8, this feature being of advantage to permit the hook to pass over a clinker effectively before moving to gripped position.
In the operation of gripping an object, the bar I4 may, of course, be moved rearwardly or the tubular holder 5 may be moved forwardly, but in all instances when the hook l6 moves over a clinker, the prong 8 should not be obtrusive, and therefore should project downwardly a lesser distance than that of the hook.
I claim as my invention,
1. In a clinker extractor, a tubular holder, an apertured semicircular bearing-block in the front end of the holder having a forwardly projecting downwardly inclined rectilinear part with a divergent terminal, an apertured semicircular bearing-block in the rear end of said holder, keepers in. the apertures and having countersunk heads in the flat sides of the bearing-blocks for securing said blocks to the lower side of the tubular holder, a semicircular operating-bar disposed in the tubular holder with its flat side engaging the flat sides of the bearing-blocks and having a downwardly and rearwardly curved grippinghook with a convergent terminal and adapted to be reciprocated to dispose its hook nearer to or farther from the inclined rectilinear part of said bearing-block, the spacing of said blocks providing a chamber in said holder beneath the operating-bar.
2. In a clinker extractor, a rectilinear, tubular holder, a rectilinear prong inclined downwardly and forwardly to the tubular holder and having a terminal, apertured, semicircular bearing-block disposed in the end of the tubular holder, an apertured, semicircular bearing-block in the other end of the tubular holder, keepers in the apertures traversing the wall of the tubular holder, an operating-bar semicircular in crosssection movably disposed in said holder with its fiat side engaging the flat sides of the bearingblocks and having a gripping-hook curved downwardly and rearwardly at the front of said prong, the spacing of said blocks providing a chamber in the tubular holder beneath the movable operating-bar.
3. In a clinker extractor, a tubular holder, a bearing-block semicircular in cross-section within the front end and having a rectilinear prong projecting downwardly and forwardly therefrom at an angle approximately of degrees, a second bearing-block of semicircular form in cross section in the rear end of said holder and providing a chamber between said blocks, means on the holder for securing the bearing-blocks thereto, and an operating-bar semicircular in crosssection within said holder slidably engaging said bearing-blocks, the front end of said operatingbar providing a single gripping-hook of approximately semicircular form having a terminal part disposed ina plane below the end of said prong.
4. In a clinker extractor, a tubular holder, a rectilinear prong having a, divergent terminal part with a fiat bottom and projecting downwardly and forwardly to the front end and provided with a bearing-block of semicircular form in cross-section disposed in said handle, a bearing-block of semicircular form in cross-section disposed in the rear end of said holder, means on said holder for securing the bearing-blocks thereto, and an operating-bar semicircular in cross-section within said holder slidably engaging said bearing-blocks, the front end of said operating-bar providing a single gripping-hook of approximately semicircular form having a terminal part disposed in a plane below the fiat bottom of the terminal part of said prong, the proportion of parts in said tubular holder providing a uniform unobstructed chamber therein between said bearing-blocks.
5. In a clinker extractor, a rectilinear tubular holder, a semicircular bearing-block in the front end of the tubular holder having a prong projecting forwardly and downwardly therefrom and provided with outwardly divergent terminal fingers, a semicircular bearing-block in the rear end of the tubular holder, and a rectilinear operating-bar within the tubular holder slidably engaging the bearing-blocks and provided with a semicircular prong, the proportion of parts being such that an unobstructed chamber of uniform area in cross-section will be formed in said tubular holder between said bearing-blocks.
