UNITED STATES PATENT OFFICE.
CLINTON S. FRITZ, OF NEW HOLLAND, PENNSYLVANIA, ASSIGNOR TO NEXV HOLLAND MACHINE COMPANY, OF PENNSYLVANIA.
NEW HOLLAND, PENNSYLVANIA, A CORPORATION OF BASE RING.
Application filed October This invention relates to the construction of hot-air furnaces and has special reference to the means for securing the base ring to the base of the furnace the object being to provide a secure fastening which will be secure against accidental blows upon the outside of the furnace. The invention is illustrated in the accompanying drawing and will be hereinafter fully described and specifi- W cally defined.
In the drawing, Figure 1 is a plane view of a base ring connected to an ash pit bottom in accordance with the invention;
Figure 2 is an enlarged detail section on i5 the line 2-2 of F igure 1.
In the drawing, the numeral 1 designates an ash pit bottom with parallel extensions 2. On the outer sides of the extensions, at the ends thereof, are lateral brackets 3 of triangular form, as viewed from above, and each having a stop lug or vertical shoulder at at the outer extremity of the respectively adjacent extension 2. The body web 5 of the bracket terminates approximately at the inner surface of the stop lug f and on the upper side of said web is a lug 6 having a notch 7 in its upper side and having its rear face slightly inclined, as shown in Fig. 2. The lug 6 extends from the ash pit extension :a) 2 to a flange 8 along the lateral margin of the bracket, and a groove 9 extent-s longitudinally of the bracket in the upper surface of the web 5', said groove being inclined downwardly and forwardly so that its bottom alines with the bottom of notch 7 which is at right angles to the rear inclined face of the lug 6. The base ring 10 is of metal and has a horizontal web 11 and a vertical web 12, but is not a complete circle, an openinebeing provided to accommodate the front ends of the extensions 2. The ends of the base ring abut the stop lugs 4-, and through the webs 12 of the ring adjacent the ends thereof, are openings 13 having flared or countersunk walls to receive the heads 14 of bolts or rivets 15 which extend through the grooves 9 and the notches 7 to be secured by nuts 16 or other anchoring elements bearing against the rear. faces of the lugs 6.
It will be seen that the base ring is secured firmly to the ash pit bottom by means which may be easily applied and which will be proof against detachment by chance blows on the outside after the entire furnace is assembled. It will also he noted that the fastening devices do not interfere in the slightest degree with the removal of ashes,
and do not require the drilling of holes in the ash door frame nor any peculiar construction of said frame.
Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is i 1. The combination of an ash pit bottom having a forward extension, brackets on the outer sides of the extension at the end thereo't',-a divided base ring having its ends bear ing against said brackets, and fastening d vices engaged with the ends of the ring and secured in the brackets.
2. The combination of an ash pit bottom having an extension, brackets on the outer sides of the extension at the end thereof, each bracket having a vertical stop lug a the extremity of the extension, a lug on top of the bracket having a notch in its upper side, and a downwardly and forwardly inclined groove in the bracket in front of said lug, a divided base ring having its ends bearing against the front ends of the brackets and abutting the stop lugs thereon and fastening devices engaged in the ends of the base ring and passing through said grooves and notches and anchored at the rear of the notched lugs.
In testimony whereof, I have signed this specification.
CLINTON S. FRITZ.
