land my improvement consists in certain supporting means for the cans or Jars containing the materials undergoing preservative treatment; the eineracteristics of my said supporting means including a Wiremesh carrying surface with suspension means comprising pivot-a1 wirefarrns, bent, and with engaging hooks, and adapted to fold together for convenience in packing.
In the drawing: Figure l is a vertical, sectional elevation of a canning boiler, with en internal, foraminous vessel and my improved supporting device. Fig. 2 is s horizontal section on the line 2--2 of Fig. l, 'and Fig'. 3 is e perspective detail of the supporting device.
ln sai, views@ indicates a looiier, supplied with e, clamping cover b, safety vs ve e and thermometer d. Upon the base oi' boiler a are Iugsa which support an internal vessel e which is supplied with' eririces5 es e. There is e clearance between the wels of vessel e' and boiler a: and aise between the bese of vessel e and boiler a.
The'supportingdevice upon which cans or jars, as j, containing vegetebies or other foodmatter to be preserved, may be supported, consist-s' of e disk g of wire mesh, having a reinforced rim g, seid disk being carried by tivo crossed Wires it, which are pivotally connected at their point oi' interM section, as et e'.
