Description

Dec. 17, 1935. F. VAN cAMP VULCANIZER Filed Nov. 9, 1934 Patented Dec. 17, 1935 UNITED STATES PATENT OFFICE VULCANIZER Application November 9, 1934, Serial No. '752,294 In Belgium June 6, 1934 1 Claim.
The present invention relates to a po'rtable vulcanizer by means of which it will be possible to vulcanize articles of different kinds, but which is specially intended for treating belting.
The apparatus according to the invention is characterized by its high Simplicity, the reduced number of elements constituting same, and a ready adjustment of the pressure required upon the articles to be vulcanized.
The apparatus is substantially fo'rmed by means of two plates, between which is inserted the article to be treated. Upright members are arranged through passages provided along the long sides of the plates, said members forming supports for eccentric or cam rollers, by means of which pressure will be imparted to the plates. said upright members have longitudinal slits underneath the bottom plate for the reception of a transverse bar, the height of which will determine previously the degree of pressure which will be imparted to the article to be vulcanized. A set of such transverse bars will give to the apparatus the quality of a press for multiple purposes, so that it may be adapted for treating any practical cases.
One form of embodiment of such vulcanizer is illustrated in the acco'mpanying drawing, in which:
Fig. 1 is an end elevation and Fig. 2- is a front or side View.
With reference to the drawing, the apparatus is formed with two metal plates l and 2, to be heated in any known manner but preferably by means of electric resistances arranged within the plates. The articles to be vulcanized are placed between the plates and the pressure required is given by means of the following elements: through the plates pass upright members 3 made of steel or any other material of high resistanee. Towards the bottom end, these members are provided with longitudinal slits l through which are passed the transverse bars 5 of convenient height.
At the upper end, the upright members 3 are steadied by means of pressure screws 'E which at the same time will wedge the transverse bars 5. The cam rollers 5 or like pressure means are rotated by means of a lever 3 engaging holes pro'- Vided at the periphery of the rollers and this partial rotary motion secures the required pressure between both plates l and 2.
Obviously, the dimensions and constructional details of the apparatus may be Vared according to the vulcanizing work to be performed, and 5 each apparatus may comprse a set of trans- Verse bars 5 of difierent dimensions, so as to secure a series of maxima pressures making the apparatus suitable for any rational treating of articles of different types. lo
The upper plate of the vulcanizer will be advantageously provided with one or more handles 9, made of insulating material, in order to allow the manipulation of the apparatus even when hot. li
As to the heating means, this will 'be advantageously constituted by electric resistances lodged in compartments provided for the purpose in each of the plates, said resistances being easily removable. 0
Obviously, the apparatus constructed according to the invention will be of easy manipulation, have a reduced weight and allow the treatment and vulcanization even upon articles presenting some diiculties to be reached at the 25 place where vulcanization is required.
In a general manner, the upright members 3 provided for cooperating to the pressure imparted to the articles may be replaced by equivalent means, and in the same direction, the trans- 30 verse bars used for the previous adjustment with respect to the pressure required may be replaced by like means, such as for instance elements fixed to the upright members and adjustable in height thereon, so as to adapt the device to the maximum pressure required.
I claim:
A vulcanizer specially for treating belts, comprising two elongated pressure plates, pairs of upright members passing through ports provided 40 along the long sides of the plates, transverse bars engaging slits at the lower ends of the upright members and passing underneath the bottom plate, pressure screws screwing in the sides of the bottom plate for steadying the upright mem 45 bers and the transverse bars, and cam rollers journalled in notches provided at the upper ends of the upright members.
