MACHINE FOR TREATING HIDES, SKINS, AND LEATHER.
Application filed May 25,
This invention relates to machines for treating hides, skins and leather of that character in which a rotatable bladed cylinder is employed, and is herein illustrated as embodied in a machine for shaving hides, Skins and leather to which it is particularly applicable.
In shaving machines as now commonly constructed and known to us, the bladed cylinder is supported in side frames erected upon a suitable base, and has co-operating with it a rotatable grinding wheel, which is also supported by the side frames and is reciprocated lengthwise of the bladed cylinder while the machine is in operation. The bladed cylinder and the grinding wheel are driven from a main shaft also supported by the side frames, the main shaft in turn being driven from a counter shaft in the tannery or factory in which the shaving machine is located.
The bladed cylinder is connected with the main shaft by belts and the grind ng wheel is usually connected by a belt with a relatively long drum which is supported by the side frames and is connected by a belt with the main shaft.
A shaving machine of this character is shown and described in United States Patent No. 802,889 dated October 24, 1905 to which reference may be had.
Machines of this character are open to the objection that excessive vibration is produced when the machine is in operation, which causes the bladed cylinder to chatter in a highly objectionable manner, thereby marking the hide, skin or leather and producing imperfect work.
The present invention has for one of its objects to provide a machine of the character described so organized that marking of the work by the bladed cylinder will be avoided or at least reduced to minimum, and with which a superior work will accordingly be done.
The invention further has for an object to provide a machine of the character described, which will be a self-contained unit and can be installed and operated in any room in a tannery or factory.
To these ends and in accordance with important features of the invention, the bladed cylinder and the driving drum for the grinding wheel are connected with the rotor of an electric motor mounted on the base of the framework, so that a relatively large propor- 1922. Serial No. 563,616.
tion of the vibration caused by the rapidly revolving rotor shaft is absorbed by the said base and has substantially no influence upon the bladed cylinder to cause the latter to chatter.
The electric motor is preferably mounted upon a support which is secured to the base and is adjustable thereon toward and from the bladed cylinder to enable endless belts free from metal connectors or fasteners to be used for driving the bladed cylinder and thereby eliminate another objectionable source of chatter. By adjusting the motor support on the base, moreove-r, the tension of the driving belts for the bladed cvlinder may be adjusted. V
These and other features of this inven tion will be pointed out in the claims at the end of this specification.
Fig. 1 is a side elevation of a shaving machine embodying this invention.
Fig. 2 is an end elevation lookin toward the right in Fig. 1. c
Fig. 3 is a plan of the rear portion of the machine, and
Figs. 4 and 5 are details to illustrate the mounting of the motor on the base, Fig. 5 being a section on the line 55 of Fig. 3.
Referring to the drawings a represents the base and Z), c, the side frames of a shaving machine, such as now commonly employed 1n tannerics and like factories, and which is provided with a bed roll 10 to support the work, a bladed cylinder 1:2 to shave the work on said bed roll, a grinding wheel 13 to keep sharp the blades of the bladed cylinder 12 and a drum 14 connected by a belt 15 with a flanged pulley 16 fast on the shaft 17 of the grinding wheel 13.
The bed roll 10 is mounted in levers 18 pivoted to the side frames i), 0, between the same and operated by a foot treadle 20 in a manner well understood.
The shaft 17 of the grinding wheel 13 is mounted in a suitable carriage 21, which reeiprocated crosswise of the machine to effect reciprocation of the grinding wheel lengthwise of the bladed cylinder. As the parts thus far enumerated are embodied in shaving machines now commonly used in tanneries and form no part of the present invention, a more detailed description of the same is deemed unnecessary.
To eliminate or reduce to a minimum vibration and other causes of chatter, an electric motor is mounted preferably on a platform or support 26 on the base a of the framework between the upright side frames Z), c, the platform or support 26 being adjustable on said base. As shown base 26 is provided with slots 27 through which are extended bolts 28, which engage the base a, and by which the platform or support 26 is firmly secured in its adjusted position.
The platform or support 26 has extended from its opposite sides, arms 29 (see Figs. 3 to 5) provided with upright portions 30, which extend above the level of the platform 26 and carry bearing boxes 31 for the shaft 32 of the rotor 33 of the electric motor 25.
The bearing boxes 31 extend beyond the side frames 3), c, and the rotor shaft 32 extends through said boxes and has mounted on it at its opposite ends pulleys 35, 36, which are connected by belts 3T, 38, with pulleys 39, 40, on the opposite ends of the shaft of the bladed cylinder 12.
The platform or support 26, is suitably guided in its movement on the base a, and a fine adjustment may be obtained by means of an adjusting screw ll carried by the platform 26 and engaging a block attached to the base a as by a bolt or bolts a3, one of which is shown in Figs. at and 5.
It will thus be observed that the rotor shaft 82, which constitutes the main driving shaft for the machine is bodily movable toward and from the bladed cylinder, to take up any slack in the driving belts 37, 38, and also to adjust the tension of the said belts, and further it will be noticed that this driving shaft is supported upon the base a, and as a result vibration produced by the rotation of the rotor shaft is absorbed by the base and the effect upon the bladed cylinder is practically nil, so that the said cylinder can be driven without chatter from this source, and therefore without marking the work, with the result that a superior grade of work can be produced with the machine.
It will be observed also that the belts 37, 38, may be endless belts and therefore free from metallic connectors or fasteners, with the result that chattering of the bladed cylinder from this source is also avoided, while provision for adjustment of the tension of the belts is made through the adjustment of the motor on the base a.
The rotor shaft 32 also serves as a driving shaft for the drum i l, and to this end is provided with a pulley d5 located between the rotor 33 and one of its bearings 31, which pulley is connected by a belt to with a pulley 47 on the shaft 48 of the drum 1d.
The side frames 5, 0, are suitably shaped at their rear ends (Fig. 1) to permit the bearing boxes 31 to be extended beyond or outside of them.
From the above description,it will be seen that the machine is a self-contained unit capable of being installed in rooms in tanneries or factories which are not provided with shafting, as it is only necessary to connect the electric motor 25 in a manner well understood, with the source of electricity.
One embodiment of the invention is hereinshown but it is not desired to limit the invention to the particular construction shown.
