LAIPEING MACHINE.
Application filed January 15, 1924.
To all whom it may concern Be it known that we, lViLLijAM F. BOKU'M and J OHN H. SnMon, citizens of the United States, residing in Philadelphia, Penn-sylvania, have invented certain Improvements in Lapping Machines, of which the following is a specification.
This invention relates to certain improve-- ments in machines for making batts or soft felts for mattresses, comforts, upholstery, &C.
One object of the invention is to provide means for controlling the movement of the lapping carriage so that its movement can be increased, or diminished, without stopping the machine.
A further object of the invention is to provide means for increasing, or diminishing, the thickness of the lap during the operation of the machine.
In the accompanying drawings:
Fig. 1 is a plan view of a lapping machine illustrating our improvements, the apron being omitted;
Fig. 2 is a side view;
Fig. 3 is an end view;
Fig. 4 is an enlarged view of the ratchet gear mechanism; and
Fig. 5 is a sectional view of the gear box.
1 is the delivery end of a Garnett machine. 2 is a frame that projects from the Garnett machine. On this frame is mounted an endless apron 3, which carries the battfrom the Gra-rnett machine to the lapping carriage 4, which is reciprocated under the overhanging frame 2. Carried by the outer end of the frame 2 are rolls 5,
' which receive the bat't from the endless apron 3. and feed it onto the endless apron 6 that is mounted on the lapping carriage.
The apron 3 of the frame 2 and the apron 6 of the carriage 4 are arranged in a manner common to lapping machines. The lapping carriage 4 has wheels 7, which travel on rails 8 that form part of a supporting frame 9 for the carriage,
Mounted in bearings 10 at one side of the frame 9 is a shifter bar 12, which is connected to a bell crank lever 13 that is pivoted at 14 to a gear box 15. This lever 13 actuates the belt shifter 16. On the shifter bar 12 are two adjustable collars 17 and 18, which can be set at any point Serial No. 686,300.
on the bar to lengthen or to shorten themovement of the lapping carriage.
In order to cushion the blow when the carriage nears each end of its stroke, springs 19 are located in front of each collar 17 and 18 and loose collars 20 are located in front of the springs. On the carriage is an arm 21, which comes in contact with the collars 20 and moves the bar 12, causing it to shift the belt and to reverse the movement of the carriage.
In the gear box are shafts 40 and 41. The
As the carriage 4 reciprocates, it strikes one stop and shifts the bar 12, reversing the mechanism. l/Vhen it reaches the other stop, it again reverses the mechanism. The stops can be adjusted on the bar without stopping the machine.
It is desirable to increase or diminish the thickness of the batt while the machine is in operation. To accomplish this, a rail 25 is pivoted at 26 to the frame of the machine. This rail is made of two angle bars spaced apart to form a channel for a block 39. The rail can be adjusted on its pivot by a handle screw 27 on which is a nut 27 attached to the outer end of the rail 25. By turning the screw in one direction, the rail can be moved at a greater angle than that shown in the drawings. When the rail is turned in the opposite direction, it is moved at a less angle in respect to the carriage.
On one side of the carriage 4 is a shaft 28 having bevel gear wheels, which mesh with pinions on the shaft 29 and the drum 30. The shaft 29 has apron wheels 31 around which the apron 6 travels. The batt is rolled on a spindle that is mounted in vertical slots 32 in the frame of the carriage, as shown at w in Fig. 3. On the shaft 28 are two ratchet wheels 33 and 34. Loose on the shaft are pawl carriers and 36, respectively, which have pawls that engage the ratchet wheels. On each pawl carrier is a segment, which meshes with a gear wheel 37 on a vertical stud that is mounted on a bracket, which projects from the carriage frame. On the gear wheel 37 is an arm 38, which carries the block 39.
As the carriage moves in the direction of its arrow, the ratchet wheels turn the shaft 28 slowly so as to feed the batt from under the rollers 5. lVhen the carriage is moved in one direction, one pawl actuates the mechanism, and when the movement of the carriage is reversed, the other pawl actuates the mechanism. Consequently, the batt is moved slowly in one direction. By changing the angle of the rail 25, the thickness of the batt can be increased or diminished.
We claim:
1. The combination in a lapping machine for forming batts, of a base frame; a carriage thereon; an. apron on the carriage; means for reciprocating the carriage; means for feeding material from a Garnett machine to the apron; means for moving the apron in one direction; a pivoted rail controlling the speed of travel of the apron; means for manually shifting the rail; and adjustable means, at or near one side of the carriage, for controlling the length of movement of the carriage, both the control for the rail and the adjustable means controlling the movement of the carriage being accessible while the machine is in motion.
2. The combination in a lapping machine, of a frame; a carriage; means for reciprocating the carriage; an apron of the car riage; means for feeding material onto the apron to form abatt; a bar at the side of the carriage; stops on the bar; an arm on the carriage arranged to come in contact with the stops to shift the bar; and a belt shifter actuated by the bar to change the direction of movement of the carriage.
3. The combination in a lapping machine, of a base frame; a carriage mounted there on; an apron on the carriage on which the batt is formed; a Garnett machine; means for feeding the material as it comes from the Garnett machine to the carriage; a bar on the frame, said bar having yielding stops at each end; an arm on the carriage arranged to come in contact with the stops; a gear b x; a driven shaft for the machine located in the box; a hollow shaft having its bearings in the box and geared directly to the driven shaft; a shaft extending through the hollow shaft and indirectly geared to the driven shaft so as to reverse the movement; a fast pulley on the reverse shaft a loose pulley located between the two fast pulleys; and a belt shifter for shifting a belt on the pulleys, said shifter being connected to the bar.
4. The combination in a lapping machine, of a base frame; a carriage thereon; means for reciprocating the carriage; means for feeding material to the carriage to form a batt; an apron on the carriage; a shaft for driving the apron; a rail pivoted to the base frame; means for shifting the rail to alter its angle; a gear wheel on the carriage; an arm on the gear wheel; a block on. the arm arranged to travel on the rail; two pawl carriers loose on the driving shaft for the apron; pawls thereon; and ratchet wheels.
secured to said shaft so that, on the reciprocation of the carriage, the apron will be moved slowly in one direction.
