To all whom 'it may concern.- l
Be it known' that I, JOHN' D. Simson, of the city of Peoria, in the count-y of .Peoria and in the Statel of Illinois, have invented alHinged Man-hole'Platc for Boilers, Steam-Generators, Heaters, or other Res@ ervoirs; and do hereby declare that the following is a fall, clean-and exact description thereof, reference be ing had to the annexed drawing making a part of this' specilicatiomin which l-ike letters of reference. refer to like parts, andin which -Figure 1 represents a'perspectire view;
Figure 2 a lateral view; andv Figure 3 a superficial view.
This device consists in hanging the manfhole plate for hoilels or receptacles in'which such plate is used on hinges, so as to open, horizontally, and to be con-A venient when Wanted to close the man-hole, instead of having to fish the piate out of the hot wa'ter within the boiler.l l y j It consists of a vertical iron, Bf, having a projecting lng, bfat either end, pierced.to.receiveanvertical bolt, d, which also passes tin-engl;'fclieyesorholesVAYA of .the horizontal hinges af ,attachedvto one end lof the plate A. The iron B is holted to the hoher-head between the hinges!" "f The bolt-holes, of the hinges a a may be made longer, at o, in a direction at right angles nfith the plate and hoi,ler-head,.'sn as. to Lpermit 'nt' tlic more ready adjustment of the plate to the interior surface of the boiler, the hinges only heilig necessary for the purpose of keepnggtlie plate suspended athe hole.
The crab D, witllits usual, holt,f,'anl1 the head which enters the nipple c in the ou'ter face of the plate,'perforn1s the otiice of making a closer adjustment of theplaiseand` a complete closing of the hole.
' Having thus fully described my invention,
W'hat I claim therein as new, and desire to secure by Letters Patent. is-f The hinged man-hole plate A forsteam-boilers, in combination with the crab D and bolt f, for securing it, substantially as and for the purpose set i'm'tli.
In testimony that, I claim the foregoing hinged man-head I have hereunto set my hand this 13th day of June, A. D. l1870. 4 v
