This invention relates to presses for cutting out sheet material, such as leather for boots and shoes, felt, etc. in which the woodblock supporting the stock is liable to become 5 uneven under repetition of the dieing out operation, and comprises improved means,
for resurfacing the stock supporting block;
The principal objects of the invention are to provide a simple resurfacing device adapt- 1 ed to be conveniently mounted on the press and performing the resurfacing operation more quickly and better than heretofore.
The invention is especially applicable to cutting or clicking presses of the beam type,
, It is a principal feature of the invention that the feeding movement of the surfacing 30 tool is effected by a power drive. In the case of a milling tool not only its rotation but also its feed is effected by power.
Specifically the invention comprlses the provision in carriage clicking presses of 25 means for feeding the resurfacing tool by the power drive moving the carriage.
Further novel features of construction and arrangement of parts will be readily understood from the description of the drawings 30 and the claims hereinafter given.
in the accompanying drawings,
Figure l is an elevation of the machine,
Figure 2 shows an elevation of the carriage on an enlarged scale.
Figure 3 is a vertical section of the carriage along its middle plane.
Figure 4: shows a vertical cross section along the line A- -B of Figure 2,
Figure 5 is be plan of the resurfacing device.
U11 the table 1 rests the clicking block 2. Above the clicking block 2 extends the beam 3, along which the carriage 4 travels on rollers 5 in suitable guides. The motion can be efiected by hand or also by means of the belt 8. The belt 6 passes over the rollers 7, 8. On the rear endof the s indle 9 of tne roller 8 is arranged a secon roller 8, over which passes the belt 10 leading from the counter 5U shaft 11 mounted below. On this shaft is the throw of right or the left, the upper or lower run of fastened a stepped pulley 12 which is driven by means of the belt 13 and the stepped pulley 14. The latter is connected with the con tinuously rotating fly-wheel 16, which can be coupled each time for one rotation with the shaft 15 by the pedal 17. The shaft 15 is of square cross-section and drives the eccentric 18. The eccentric 18 imparts to thepressure member 19 the clicking movement and can be shifted laterally with the carriage 4. On the carriage is fastened an upright shield 20, in which the shaft 23 with the double cam 24 and the control lever 25 are journaled. By
the control lever towards the the belt can be clamped to an upper or lower surface of the shield, so that the latter will be carried along with the whole carriage to one side or the other.
To the carriage 4 a slideguide 27 is removably clamped by means of a stirrup 26, see Figure 3. The carrier 28 of a small electromotor 29 is movable in this slide guide. The lower end of the shaft of the electrometor carries a milling tool 30. The'move'ment of the carrier 28 in the said guide is effected by means of the screw-spindle 39, which can be rotated either by means of a hand wheel 32 or an automatic control device.
With automatic control, see Figures 2 and 4, a ratchet wheel 33 is mounted on the screwspindle 39 in lieu of the hand-wheel 32, said ratchet wheel cooperating with two pawls 34, 35. These pawls are pivoted to a rod 36 and are. pulled towards each other by a spring 37 causing the pawls to havea tendency always to engage with the ratchet-wheel 33. The rod 36 embraces for its guiding with its lower forked end the foremost end of the screw-spindle 39, and it is pivoted with its upper end to the lateral right arm 40 of the control lever 25 by means of the pin 38. In the end-positions of the carriage the right arm 40 or the left arm 41 comes into contact with the fixed oblique stops 42, displacing thereby the control lever 25 and coupling the upper or lower run of the belt with the carriage 4:. Reversing of the lever 25 is accelerated and secured bythe spring-pressed snap-bolt 43 terminating in a knife-edge, said bolt cooperating with a knife-edge on the lever 25. If the snap-bolt 43 is turned by 90,
, a notch provided in its knife-edge engages the knife-edge 44, thus securing the control lever 25 in its inoperative central position.
If the clicking block is to be planed, the belt 13 is placed upon the stepped pulleys 12, 14 in such a manner that the crossed belt 10 for moving the carriage will run with a considerably reduced speed than during the clicking operation. The guide 1-47 is attached to the carriage 4 in such a manner, that the electromotor'29 together with the milling tool can be moved across the clicking block. If the motor 29 is started and the snap bolt 43 passed from. the locking position into the position, in which the cam 24: of the control lever 25 is coupled with the belt 6, the carriage will move along the clicking block. In the end positions of the carriage the arms 40,- 41 ofthe control lever 25 slide upon the inclined stops 42 and reverse the direction of movement of the carriage. At the same time the ratchet-wheel 33 and the screw-spindle 39 are rotated by the swinging movement ofthe control lever 25 and the pawls 34, 35, so that the electromotor together with the milling tool is shifted transversally to the clicking block by the width of the chip. These proceedings will repeat automatically, until the millingtool has passed over the whole width of the clicking block and the control lever has been put by hand into its inoperative central position. Then the stirrup 26 of the slide guide 27 of the motor is slackened, turned by 180 and screwed tight again, in order to plane the other end of the clicking block in the same way.
As will be noted, the shifting and feeding movements can be carried out automatically, as well as by hand. But it is an essential characteristic feature of the invention, that the milling tool can be fed by means of a motor, that this tool is in case of a carriage clicking machine of the beam type mounted on the clicking carriage, and that the motor drive of the carriage is utilized for the planing of the clicking block.
Having described my invention, what I claim is:
1'. In a cutting-press, a stock supporting wood-block, a beam above the wood block, a carriage movable 0n the beam parallel to the said block, a pressure applying member movable within the carriage perpendicularly to the block, and means for resurfacing the wood-block arranged on the said carriage.
2. In a cutting press, a stock supporting wood-block, a beam above the wood block, a carriage movable on the beam parallel to the said block, a pressure applying member movable within the carriage perpendicularly to the block, means for resurfacing the woodblock arranged on the carriage, and power surfacing means on the wood-block.
3. In a cutting press, a stock supporting wood-block, a beam above the wood block, a carriage movable on the beam parallel to the said block. a pressure applying member movable within the carriage perpendicularly to the block, means for resurfacing the woodblock arranged on the carriage, power means for feeding the carriage and the resurfacing means on the wood-block, and means for changing the speed of the feed.
4. In a cutting press, a stock supporting wood-block, a beam above the wood block, a carriage movable on the beam parallel to the said block, a. pressure applying member movable within the carriage perpendicularly to the block, a slide guide on the carriage and perpendicular to the direction of movement of the carriage, and means for resurfacing the wood-block movable in the said guide.
In testimony whereof I aflix my signature.
