H. A. HATCH CONDENSER Filed Oct. 16, 1920 'l/V VEN TOR mw ffl/322@ A TTOH/VEY mittd to cool off at atmospheric temperature.
Thel elements as thus constructed are measured as to capacity and stocked in appropriate bins.
When' condensers of a definite capacity are desired, the properelements are selected and an identifying plate 4 of ibre or other suitable material is placed on the element. This plate is provided with apertures 5 for a purpose to be hereinafter described. Underneath the elements are placed a suitable number of mica plates 6, 7, so that the overall thickness of the condenser will be thatsuitable to the Width of the terminal clamps soon to be described. It is of course 'understood that the plate 4 may also be varied in thickness and that if desired the width of the clam may be varied at will. 4These sheets 6, are made slightly wider than the elements 2 so that when the clamps are applied, they will be parallel to one another and perpendicular to the Ifilms. The clamps vare each made up of sheet metal into an open sided boxlike structure protecting the lateral edges and corners of the element.
denser is effected.
The sheet from which the clamp is formed comprises a main body portion '9 having lateral ears 10, 10 on one side and ears 11,. 11 on the other side, an additional terminal member 12 being also struck out on the same rside as the ears 11, 11. Another pair of end ears 13, 13 are also provided,
. The clamp" is wrapped laround the condenser element as is clearly indicated in Figures 2, 3 and 4, the ears 10 being bent into the apertures 5 of the fibre sheet so as to retain the clamps in place. v
The tinfoil ends 14 of the element are folded back upon the fibre retaining plate of the element and suilicient pressure is applied to the clamps as they are positioned on the element to mechanically securely hold them in place and t'o -make good electrical Contact with the tinfoil sheets without the use of solder.
The element being already a compacted mass, the pressure of the clamps on the element does not alter the distances between the dielectrics and sowhile the terminal clamps of the element are rigidly held in place no change in the capacity of the con- In Figure A6, I have shown but one ear 10* instead of two and the form of terminal member -12 is slightly dilerent.
-It is of course apparent that condensers of suitable capacity may be made by combining several elements or by splittingFone urthermore by using a vsheet 401 different thickness a single clamp 8 may serve for condenser elements ofvconsiderable yrange in thickness. The built' up condenser, according tomy invention, has the capacity aycredited to it by the identifying slip of paper inserted between 'the la t two layers of mica. The connecting of the terminal vclamps to the tinfoil without the use of solder, renders the condenser longer lived due to the absence of the soldering flux which because of the acid which is always present therein destroysfthe tinfoil in time. The
'element is. protected from,destruction by body ortio n.
