c. DE v. GRANT APPLIANCE FOR SUPPLYING DRY STEAM T0 COOKING OVENS Filed Feb. 1927 Patented Jan. 24, 1928.
UNITED STATES PATENT OFFICE.
APPLIANCE FOR SUPPLYING DRY STEAM TO COOKING OVENS.
Application filed February 4, 1927, Serial No. 165,882, and in Great Britain February 4, 1926.
For supplying dry steam in a gas or other cooking ovenapparatus such as described in specification of prior Letters Patent granted to me. No. 1,5 l l,976 is especially designed. Such apparatus comprises a steam generator arranged in the oven and provided with a longitudinally extending superheating chamher through the length of which the steam passes prior to issuing into the oven.
In practice it is found with such apparatus that the steam passes so quickly through the superheating chamber or through the pipe within the oven that it is not superheated to the extent desired and the object of the present invention is to provide in the said superheating chamber or the said pipe a device of any known or suitable type adapted to retard the flow of steam through said chamber or pipe. Conveniently the retarding device may be of the helical type that will cause the steam to take a helical path through the superheating chamber or pipe and deflect it towards the wall of the said chamber or pipe during such path. In this way the degree oi" superheat is increased and the appliance is rendered more eflicient.
The superheating chamber in .the device described in the said specification No. 1,544,- 976 may and usually does consist of a tube of circular cross-section to which saturated steam is admitted at or near one end and from which the dried or superheated steam passes into the oven through a hole or nozzle at or near the other end of the tube.
The accompanying drawing illustrates a device as described in the said prior specilication No. 1,544,976 embodying the present invention.
Fig. shows the device in sectional ele- VfltlUll, and i F 1g. 2 15 an end view partly 1n section Saturated steam passes from the generator 1. i
helically twisted metal 7 adapted to fit wit-hinthe superheating tube 3, the end of said retarding device nearest the steam inlet 5 .beingshaped as shown so as to divide the flow of steain'into two helical paths one on each side of the twisted metal body. The other end of the retarding device 7 terminates in a short axial stem 8 or is otherwise so shaped as not to restrict the flow of superheated steam through the outlet or nozzle 6. The length of the helical retarder 7 may, or course, be varied as found desirable and in some cases the retarder may be formed in more than one section. Preferably it is formed in one piece as shown and extends the full length of the superheating tube 3.
The helical retarding device is shown as being mounted stationary in the superheat- .1ng chamber, and as being formed of an imperforate metal plate; it may however be mounted in any other approved way, and may be provided with any approved perfora tions.
. lVhat I claim is:
1. Means for supplying dry steam to anoven, comprising a steam generator, a steam superheating tube arranged horizontally and secured outside the steam generator to the top thereof, said tube having an inlet at one end communicating with the steam generator and having an outlet for dry steam at. its other end, and a. retarding device for the steam arranged in the said tube.
2. Means for supplying dry steam to an oven as set forth in claim 1, the said tube being connected with the steam generator by a pipe which delivers the steam longitudinally of and at the axis ot the tube, audthe said retarding device being Oilii a helical type and constraining the steam to flew in a helical path.
In testimony whereof I aliix my signature.
CHARLES on VERE GRANT.
