Filed June 21. I928 specialized workshops or fa Patented Nov. 24, 1931 MAURICE CHARLIER,
0F BRUSSELS, BELeImvr PROCESS or SWAGINGDENTAL P'LATESV Application filed June 21, 1 928, Seria1 No. 28f7,2 19,.and in Belgium Julie 25, 1927.
The present invention relates to a new and improved method of swaging metal plates for dental apparatus, and more particularly the kind of plates made of metal of high. 5 mechanical resistance such as rustless steel. The object of this invention is to make it possible and practical to manufacture such high resistance metal plates in the dentists laboratory itself, without having to call upon ctories.
The metal plate to be swaged on a metal die is fixed in position by means of a lever with adjustable pressure; between the operating end of the lever and the plate is interposed a mass of soft metal, such as lead or tin, which is subjected to hammering from the centre of the die outwards this soft metal may be in the form of a strip which is wound into a spiral as the hammering proceeds from the centre outwards, said strip being held by said lever with the interposition of a small plate of suitable size.
Instead of a strip the soft metal may be shaped as a plate of the size to be swaged and of suitable thickness.
The device for supporting and clamping the die, the plate to be swaged and the accessory parts comprises a base on which is arranged a standard serving as a pivot for a lever which presses on the die towards the centre thereof; any suitable clamping means may be adapted to said swinging lever.
In order that my invention may be better understood I have illustrated by way of example in the accompanying drawings, an apparatus for carrying outthe process accord: ing to the invention. In the drawing:
Fig. 1 is a vertical section of a die for swaging, on which is laid the plate to be hammered. Figs. 2 and 3 are plan views corresponding to Fig. 1, diagrammatically showing the winding of the soft metal strip in two successive phases.
Fig. 4 is an elevation ,of the apparatus complete.
Fig. 5 is a plan View of the clamping lever. Referring to said drawing, 1 denotes the base of the apparatus; a standard 2 screwed in said base forms a horizontal pivot 5 for V the swinging lever milled at its flattened end 4.
,ATENT OFFICE v 3 which is serrated or This lever is provided with an oblong slot 6 through which extends a threaded rod 7 hooked at its lower end 9 to an eye 10 screwed into the base 1, while its end above the lever 3 carries a clamping nut 8.
11 is the metal die on which is to be swaged the high resistancemetal plate 14, which is for example of rustless steel; this die is secured in position on the base 1 by lugs integral with the latter, or by any other suitable means.
The swaging operation is effected in v the following manner: The dental plate 14 is first subjected to to shape it to the is placed on the die in the whole must be pressed;
a brief hammering in order as shape of the palate; it then r f position'wherethe At that moment there is introduced between the dental plate 14 and the end 4 of the lever 3 a strip 12 of soft metal, for example lead or tin, the first coil of which, of spiral shape, is clamped bythe nut 8 of the lever 3, which firmly secures the whole in position and presses on the centre of the plate. Successive coils of the soft metal strip are then pressed and hammered, as they are gradually wound, the effect of which is to press and spread the dental plate 14 without-folding or tearing the metal. g
A set of intermediate plates of various thicknesses permits of maintaining and pressing each portion of the soft metal strip or plate while hammering is gradually proceeded with, these plates being placed under the finger of the lever. The strips or plates of soft metal may be cast to various sizes by means of moulds so that the same'soft metal can be used indefinitely. i
From the foregoing it will be understood that the dental exactly follow the contour of'the die owing to the hammering with interposition of a 1 plate 14 thus obtained will V The cost of manufacturing such a dental due plate present plates of gold or other precious metal, on the one hand because its weight will be much less, and on the other because its cost, by equal weight, is lower.
I claim:
In a process of swaging th-inplates of high mechanical resistance, placing the plate on a die, placing a strip of soft metal on the plate, one end of said strip being approximately at the centre of said plate, plate by mechanical pressure, Winding said strip in a spiral around its fixed end and hammering said strip while'it is being wound from the centre outwards.
V In testimony whereof I afli-X mylsi-gnature.
Y MAURICE GHARLIER' will be much less than that of the v fixing said end on the r v gradually V
