GEORGE GLAUDEL, OF CRYSTAL CITY, MISSOURI.
SILVEFHNG-TABLE SPECIFICATION forming part of Letters Patent No. 794,858, dated July 18, 1905.
Application filed April 15, 1905. Serial No- 256,721.
To all whom it may concern.-
Be it known that I, GEORGE GLAUDEL, a citizen of France, residing at Crystal City, in the county of Jefferson and State of Missouri, have invented certain new and useful Improvements in Silvering-Tables, of which the following is a specification.
My invention relates to silvering-tables.
Mirrors have heretofore been silvered in the following manner: Each glass is placed upon a washing-table and thoroughly cleansed, after which it is transferred to slabs of iron or cement forming the top of the silveringtable. The supports for these slabs form a box or tank, in the bottom of which steamcoils are arranged for the purpose of heating the glass to the proper temperature for silvering. Before applying the silvering solution the glass is leveled, so that it may be coated uniformly over the entire surface. This leveling process has heretofore been done by placing wedges or chips under the low sides of the glass. Many disadvantages are to be found with the methods now employed, among them being a loss of time in transferring from the washing-table to the silveringtable, the inaccurate leveling of the glass, and the loss of silvering solution due thereto.
The object of my invention is to provide a table upon which all of the operations necessary in the preparation and silvering of mirrors may be performed.
A further object is to provide a table having a leveling device attached thereto which will quickly and accurately level the glass and retain it in said position.
l/Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as. will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of theadvantages of the invention.
In the drawings, Figure 1 is a top plan view of my invention. Fig. 2 is a longitudinal crosssection, and Fig. 3 is a transverse cross-section.
Referring to the drawings, in which like numerals represent corresponding parts throughout the several views, 1 and 2 are sides and ends of the silvering table or tank provided with a slat bottom 3. Resting on these slats are steam-coils 4, to which steam is supplied. A row of horizontal cross-pieces 5 are secured to the sides about midway between the top and bottom of the table. Bars 6, carrying wedges 7 and supported by cross-pieces 5, are held from transverse movement by guides 8, secured thereto. On the outer ends of bars 6 are formed racks 9, engaging pinions 10, keyed on shaft 11. This shaft, suitably mounted in the extensions 12 of sides 1, is provided with an operating-crank 13, by which the bars 6 are longitudinally moved. Racks 14, which support the glass before it is leveled, are hinged at one side to bar 15. The opposite side is supported by strips 16.
Mounted upon the cross-pieces 5 are leveling-rods 17, which are connected at their lower ends to levers 18. These levers carry Weights 19, to which are pivoted catches 20, provided with teeth to. engage projecting edges of offsets in bar 6. WVedges 7, located on bars 6, are adapted to be moved forward under weights 19 to lift them, which will operate to lower the leveling-rods attached to the opposite end of lever 18.
Secured to the sides 1 of the table and extending the full length thereof are levelingplates 22, on which leveling-bars 23 rest when in position above the glass. These bars are provided with means for moving them over the tank when it is desired to level a glass and also to remove them to one end after they have served their purpose. This means consists of shafts '24 and 25, carrying drums 26 and 27 The bars 23 have their ends bent at right angles to engage guides 28, located at the sides of the table. These guides are secured to vertically-movable racks 29, which mesh with pinions 30 on'shafts 31. Ropes 32 are attached to the forward leveling-bar and to drums 26 and 27. It will be observed that by turning crank 25 the ropes will be wound around drums 27, and the forward leveling-bar 23 will travel toward that end of the table. As each leveling-bar is connected by a short flexible connection 33 to the next succeeding bar, the movement of the first will be carried onto the remaining bars. By turning crank 31 the leveling-bars 23 will be raised clear of leveling-plates 22, thereby preventing the uneven wear of the same and scratching of the plate-glass.
Located above steam-pipes 4 is an inclined canvas trough 34, which communicates at its lower end with a receptacle 35, provided with cocks 36 and 36, said cocks being provided with suitable conduits leading to a water-box and settling-box, respectively. The trough 34 is attached at one side to roller 37, onwhich it is adapted to be wound by turning crank 37. To the opposite side of the trough are attached ropes which are wound around roller 38 when crank 38 is turned. By this means the canvas trough may be placed in position over the steam-pipes or withdrawn, as desired.
In practice my silvering-table is used as follows: By turning crank 13 to the left bar 9 is moved forward. The first part of its movement releases catches 20. Upon further movementwedges8 are forced under weights 19, which arelifted thereby, and leveling-rods 17 are lowered. The canvas trough 34 is drawn into position over the steam-pipes by turning crank 38. The glass is then placed on racks 141 Crank 31 is turned to the left, which operates to raise guides 28 through racks 29 and pinions 30. The upward movement of these guides lifts leveling-bars 23 above the leveling-plates 22. The crank 25 is then operated to wind ropes 32 on drums 27, which draw leveling-bars 23 to their respective positions over racks 14 and glasslying thereon. The guides 28 are then lowered, allowing bars 23 to rest upon plates 22, said plates having been previously leveled and secured in position by thumb-nuts 22. In this way a perfectlylevel surface is secured above the glass. The next step is to release the weights 19 by turning crank 13 to the right, which withdraws the Wedges 7 and permits the Weights to descend. This downward movement raises supporting-rods 17, which in turn lift the glass against the under surface of the leveling-rods 23, said rods being of sufficient weight to prevent further upward movement. This adjustment of the glass occurs before the toothed edge of the offsets in bars 6 has come into engagement with the teeth on catches 20, which engagement takes place during the latter part of the movement of bar 6 and serves to hold the weights from further downward movement when the leveling-bars 23 are drawn from over the racks 14 through the operation of crank 24. The racks 14 are then lifted at one side to give the glass an inclined position, which allow water used to cleanse it to drain ofl into canvas trough and out through cook 36. When the glass is washed, racks 14 are lowered and the glass will rest on rods 17. The silvering solution is then poured on the glass. Canvas trough 34 is withdrawn from over steam-coils 4, allowing said coils to heat the glass to required temperature. When silver is all deposited, trough 34 is again placed in position over the coils 4, and the surplus solution is-allowed to drain into it and is carried off by cook 36 to a settling-box.
Having thus described my invention, what I claim as novel, and desire to secure by Letters Patent, is
1. A silvering-table, comprising heating means an abutting surface adapted to be leveled, and leveling mechanism adapted to raise the glass against the previously-leveled abutting surface.
2. A silveringtable, comprising heating means, an abutting surface adapted to be leveled, leveling mechanism adapted to raise the glass against the previously-leveled abutting surface, and means for removing said levelingsurface.
-3. A silvering-table, comprising heating means, an abutting surface adapted to be leveled, and leveling mechanism adapted to raise the glass against the previously-leveled surface and retain it in said leveled position.
4. A silvering-table, comprising heating means, leveling mechanism,and means, located between the heating means and the glass, for catching the surplus silver.
5. A silvering-table, comprising heating means, leveling mechanism,and means, located above and adapted to be Withdrawn from over,
the heating means to catch the surplus silver.
6. In a silvering-table, leveling mechanism comprising a leveling-surface located above the glass, and means for bringing the glass in contact with said surface.
7. In a silvering-table, leveling mechanism comprising a leveling-surface located above the glass, means for bringing the glass in contact with said leveling-surface, and means for retaining the glass in said leveled position.
8. In a silvering-table, leveling mechanism comprising a leveling-surface located above the glass, means for bringing the glass in contact with said leveling-surface, and means for removing said leveling-surface.
In testimony whereof I affiX my signature in presence of two witnesses.
GEORGE GLAUDEL.
