ANDR OLIER, 0F CLERMONT-FERRAND, PUY-DEeDME, FRANCE.
GALEND'ER.
To all 'whom it may concern:
Be it known that I, ANDR OLIER, citizen of France, residing at Clermont-Ferrand, Puy-de-Dme, in the Republic of France, have invented new and useful Improvements in Calenders, of which the following is a specification.
My invention relates to calenders or roll'- ing presses such as those used in the treatment of plastic materials and heated metal for obtaining sheets or bands of a uniform thickness and also bands or bars of any desired shape in cross section, this result being obtained by the use of rollers of the proper outline.
The invention is intended primarily to operate upon sheets of rubber and analogous plastic material.
It is well known that instead of using solid cylinders of the proper cross section, profiled rings or sleeves may be mounted on the roller shafts, so that bands or bars of very different cross sections may be readily obtained on the same machine by merely changing the rolling sleeves on the shafts. Up to the present, said rolling sleeves are secured on the shafts outside the side frames of the machine for the purpose of facilitating and accelerating the mounting and dismounting of the sleeves. This construction has however the great disadvantage of submitting the shafts and sleeves to vibrations due to the fact that the same are held at one end only, said vibrations increasing as the work of the machine is harder. lt results therefrom that the strain on all parts of the machine is absolutely dissymmetric and irregular. The work is not performed regularly, and diiferences exist in the thickness of the rolled bands or bars, which prevent of using such machines for precise work.
This invention has for its object to entirely remove this objection while assuring the removability of the rolling sleeves, by mounting the sleeves between the side frames of the machine, through the medium of an auxiliary frame removably mounted in one side frame. The invention is applicable to calenders having any number of rollers and rolling sleeves of any desired shape.
One embodiment of my invention is shown by way of example in the accompanying drawing in which- Figure 1 is a side elevation of a proiiling calender with four rollers, two of which Specification of Letters Patent.
Application led February 2, 1910.
Patented Sept. 19, 1911.
Serial No. 541,449.
being removable and all of the rollers being mounted between the side frames. Fig. 2 is a vertical section of the machine taken through the axis of the rollers.
Referring to the drawings, 1 and 2 indicate the side frames of the machine. Four rollers 3, 4, 5, 6, are mounted between the same so as to obviate to any vibration in the working, the rollers being firmly sup ported at both ends. The upper and lower rollers 3, 6, do not bear any profiling sleeves while two profiling or rolling sleeves 4a, 5a, are mounted on the rollers 4, 5, respectively. The upper and lower rollers are mounted in a known manner in sliding blocks 7, 8, which may be adjusted vertically by means of worm gears 9, 10.
The intermediate rollers 4, 5, are supported at one end in the frame 1 as usual.
The roller 5 rests directly in the frame, while the end of the roller 4 is carried in a bearing 4b which may be adjusted vertically by means of wedges 11 movable in a direction at right angles with the axis of the rollers, as well known in the art. Said wedges are operated as hereinafter described. The four rollers are geared at this end by pinions 12, 13, 14, 15, and the roller 5 has secured thereon the driving wheel 16. According to theinvention, the rolling sleeves 4a, 5a, fitted on these rollers may be easily removable when necessary. For this purpose, the other ends of the rollers 4, 5, are not mounted directly in the side frame 2 of the machine but in an auxiliary frame 17 which is inserted in an opening 18 provided in the side frame 2 and is secured to the side frame by four nuts 19 screwed on bolts on the side frame passing through lugs 20 of the removable frame. The opening 18 is rectangular at the top and semi-circular at the bottom and has such dimensions as to permit the removal of the sleeves of the largest diameter used in the machine.
The right end of the cylinder or roller 4 (Fig. 2) is mounted in a movable bearing 21 which may be adjusted by means of wedges 22 movable in the frame 17 in a direction parallel to its axis. The wedges 22 are each provided with a threaded stem 23 working in a nut 24 which is held against axial displacement by brackets 30 secured to the auxiliary frame by bolts 81. The nuts 24 are set in rotation by skew wheels 25 operated by a worm 26 secured to a shaft 27. The shaft 27 extends horizontally Y frame 2.
through bearings 28 and may be operated by means of a hand wheel-29. On the shaft 27 is keyed a miter gear 32 which operates the wedges located on the other side of the machine through the medium of shafts 33, 34, 35, connected by miter gears as shown in Fig. 2. The wedges on both sides of the machine are thus operated at the same time through one hand wheel 29, so that the position of the roller 4 may be accurately adjusted. For changing the rolling sleeves 4a, 5a, in view of rolling bars of another shape, it is only necessary to unscrew the nuts 19 and disengage the miter gear 32. The whole removable frame 17 together with the wedge operating means may be then withdrawn laterally from the side For supporting the removable frame during the removal, guide rods 36 are fixed in the side frame 2 and lugs 37 provided on the frame 17 slide on the rods for supporting said frame. The rods 36 may be temporarily supported at their outer ends by suitable brackets if necessary. They may also be removably secured to the side frame 2. When the auxiliary frame 17 has been removed, both rollers 4, 5, are supportl ed in the side frame 1 only, the driving wheel 16, acting as a counterweight. Access may then be had to the rolling sleeves 4a, 5a, so that the same may be easily removed and replaced by others of the desired shape.
' sleeve Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a calender of the class specified the combination of two side frames, rollers located between said frames, rolling sleeves mounted on some of the rollers, and an auX- iliary frame supporting one end of the carrying rollers and removably mounted in one of the side frames, substantially as described and for the purpose set forth.
2. In a calender of the class specified, the combination of two side frames, rollers located between said frames, rolling sleeves mounted on some of the rollers, an auxiliary frame supporting one end of the sleeve carrying rollers and removably mounted in one of the side frames, and means for supporting said auxiliary frame upon its side frame during its removal therefrom, substantially as described and for the purpose set forth.
3. In a calender of the class specified, the combination of two side frames, rollers located between said frames, rolling sleeves mounted on some of the rollers, an auxiliary frame supporting one end of the sleeve carrying rollers and removably mounted in one of the side frames and means carried by the auxiliary frame for adjusting the rollers vertically, substantially as described and for the purpose set forth.
In testimony lwhereof I have signed my name to this specification in the presence of two subscribing witnesses.
ANDR OLIER.
