SETH D. TRIPP, OF LYNN, MASSACHUSETTS.
Letters Patent No. 108,216, dated October 11, 1870 antedated October 1, 1870.
IMPROVEMENT INY'LEATHER-BUFFING MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
The discharge-nozzle is adjustably attached to the drum of the fan, so that the dust may be conveyed in any direction, as may be required for different situations, and the mandrel is provided with tapered journals and adjustable tapered boxes, held between set-screws, for. moving up from time to ti me as they wear loose, and the boxes are provided with adjustable holding-rods.
The sanding-rolls are made of wood, with a central hole for the reception of the mandrel, on which they are secured by set-screws, so as to be readily removed for the substitution of others when worn out.
Figure l is a transverse sectional elevation of my improved machine.
Figure 2 is a front elevation of the same.
Figure 3 is a longitudinal section through the butting-rolls.
A is the, hollow case mounted, in an upright position, on .a frame, B, and provided with a fan-blower drum, 0, and a fan, D, at the bottom; also, with a slot, E, along the vertical face F, near the upper end. 7
The said fan-drum C is provided with a dischargenozzle, G, fitted to the periphery, and designed to be attached so that it may be adjusted to any position thereon, as may be required in setting-thc machine in diii'erent positionsior discharging the dust, after which the hole may be cut through the periphery of the drum, coinciding with the .hole of the nozzle for the discharge through the case or drum.
H is the mandrel for the support of the buffingrolls, mounted near the top of the case, and parallel with the slot E in braces I. 1
These boxes are tapered internally, and the journals H of the mandrelcorrespondingly fitted thereto.
a a are grooves formed on opposite sides of the boxes I, and
1) l1, set-screws,- whose inner ends enter the same; this arrangement permitting the longitudinal adjustment of the boxes to compensate for wear of the parts. I
The said set-screws b are supported in the, upper ends of the'end frames B.
It is intended that the boxes I shall be held by the screws 1) loosely, so that they may be moved without disturbing the said screws after the shaft and boxes have been properly lined; and, for bolding them in place, I have provided the rods (1 with arms, 0, to slide in and out of holes in the top ofthe frame, and be secured at any required position by set-screws f, the said arms 0 rising up in front of the outer ends of the boxes.
In this way the boxes may be adjusted and secured in position more readily than can be done by means of the screws I), if screwed up against the boxes tight enough to hold them against end mo-.
.tion.
This mandrel projectsat one end far enough-to receive the driving-pulley K, on which a. belt from the fan-shaft works, to impart the rotary motion.
L is the disk or roll, for sand papering the partof the sole next the heel, for which purpose it is required to project considerablyfrom the other part, M, which is the roll for working on the otherparts; and
N is the brushing'roll,forremoving the dust.
The roll M is a long sleeve, of wood, having an axial hole, for the reception of the mandrel H, and it is secured thereto by set-screws.
The rolls L N are disks, of wood, attached to the ends of M, and the whole may be readily slipped off the mandrel, when required, for the substitution of others.
The said rolls L and M are covered with sandpaper, or other similar substance, and the buffing or sand-papering operation is performed byplaeing the soles against the papercd surfaces while revolvingat high velocity, as is well understood.
It will be seen that, by the employment, with the sand-papering rolls, of the fan-blower and hollow case leading thereto, the dust formed by the buffing operation, andwhich is injurious to the operator, is carried away from him, and the injury and annoyance thereof prevented.
The top of the case A isjointed and hinged at 0, so that the part 1? thereof may be raisedout of the way for the removal of the rollers, or for other purposes.
Having thus describedmy invention,
. I claim as new and desire to secure by Letters Pat ent- The combination of sliding rods d, arms e, set-, screws D f, and grooved boxes I, all relatively con structcd and arranged, as and for the purpose specified.
