Application filed November 20, 1924. Serial No. Yo 1,023.
T (ill whom it may concern:
Be it known that I, FRANK T. "COPE, a citizen ofthe United States, residing at Salem, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Heating Furnaces, of'which the following is a specification.
This invention relates to furnaces for heating small articles such as machine parts of irregular shape which cannot be easily handled in a furnace of usual construction.
- The objects of the improvement are to pro vide a heating furnace in which small machine parts such as bushings and the like may be easily and readily heated in large quantities, and in which the articles ,to be treated are continuously passed through the furnace at the desired speed.
An embodiment of the invention is illustrated in the accompanying drawings, formingrpart hereof, in whichi igure 1 is a longitudinal,-vertical section of the furnace;
Fig. 2', an elevation of the discharge end of the furnace; and
Fig. 3, an elevation of the charging end of the furnace.
Similar numerals refer to similar parts throughout the drawings. The furnace proper is illustrated at 1, and is preferably spaced from the floor by the adjustable legs 2, and provided with the elongated heating chamber 3 which may be heated electrically or'otherwise and is provided with the reduced charging and dis-- charging openings 4 and 5 respectively.
The hearth of the furnace comprises a metal plate 6 extending entirely through the heatin chamber and protruding for a considera le distance beyond the charging end thereof, and adapted to receive a combined reciprocating and oscillating motion.
For this purpose a longitudinally movable, pivotal connection is provided at the forward or discharge end of thehearth and may comprise the balls 7 retained in .the depend-,
in channel 8. Y a
11 order to produce this 'uli'ar motion, a rocker shaft 9 is mounte in bearings v1O located, beneath the rear or chargmg endportion of the heart-h. A air of rocker arms 11 are mounted upon t e shaft 9 and provided with the forwardly, disposed, upper end portions 12 pivotally connected to operator.
depending ears 13 upon the under side of the hearth. I
An upright 14 is spaced from each end of the rocker shaft 9 andconnected near their upper ends with a cross bar 15, pull springs 16 being vconnected to said cross bar and to the rocker arms 11, to normally hold the same in engagement with the transverse bumper 17 carried upon an I-beam 18, sup ported between the uprights 14.
The rocker arms 11 are in the form of bell cranks, the forwardly disposed arms 19 thereof converging and being connected to the block 20, which isnormally held in engagement with the cam 21, by means of the springs 16, said cam being mounted upon the shaft 22 arranged to be continuously driven from any suitable source of power in the direction of the arrow, shown in Fig. 1.
In operating the furnace to heat small articles such as machine parts of an irregular shape or the like, the articles to be treated are piled .upon the protruding rear end of the hearth, and as the same is continuously reciprocated and oscillated, ending each movement with a quick forward motion and sudden stop, the parts are quickly scattered and spread out evenly over the surface of the hearth, the contral, longitudinal depression therein and the side flanges 23 assisting in properly spreading the articles and preventing the same from being jolted off of the hearth.
With each sudden jolting movement of the hearth, the articles are moved forward a slight distance and as they reach the forward or discharge end of the hearth, the upturned flange 24 prevents them frombeing "acci- I dentally thrown out of the furnace, holding them in position to be easily removed by the From the above, it will be evident that the v herein described furnace provides means for easily a-ndreadilyhandling small, irregular shaped articles in large quantities, and permits of their being passed through the furnace and properly treated in a short space of time. p
Iclaimz- A '1.A heating furnace including a heating chamber, a hearth located therein, anti friction means supporting the forward end of the hearth, a bell crank pivotally con nected to the rear of the hearth, a bumper adjacent to the bell crank, a spring urging the bell crank toward the bumper, and a. cam for moving the bell crank away from the bumper and releasing the same.
2. A heating furnace including aiheating chamber, a hearth located therein, antifrict-ion means supporting the forward end of the hearth, a lever pivotally connected to the rear of the hearth, a bumper adjacent to the lever, means normally urging the lever toward the bumper and means for moving the lever away from the bumper and releasing the same. 1
3. A heating furnace including a heating chamber, a hearth located therein, antifriction means supporting the forward end of the hearth. a lever pivotally connected to the rear of the hearth, a bumper adjacent to the lever, spring means normally urging the lever toward the bumper and means for moving the lever away from the bumper and releasing the same. 4. A heating furnace including a heating chamber, a hearth located therein and means for reciprocating the hearth, said reciprocation comprising a slow, backward movement, and a rapid forward movement, ending in a sudden stop whereby" articles upon the hearth are caused to slide forwardly thereon with each operation of the hearth.
5. A heating furnace including a heating chamber, a hearth located therein and thereon.
6. A heating furnace including a heating chamber, a hearth located thereon, balls supporting the forward end of the hearth, a bell crank pivotally connected to the rear of the hearth, a. stationary bumper adjacent to the bell crank, a spring urging the bell crank toward the bumper and a cam for moving the bell crank away from the bumper and releasing the same.
In testimony that I claim the above, I have hereunto subscribed my name.
FRANK T. COPE.
