PARK AND CEMETERY. 
was emptied, and now that ravine is 
filled full, and there a broad field of 
grassy lawn prevails. 
For interment purposes the ceme- 
tery has been divided into 39 sections. 
Besides these, however, there is a deal 
of unoccupied and unplatted land, ex- 
cellent for burial lots, and much 
woodland hill that is unfitted for in- 
terments. Of the 39 sections, all ex- 
cept No. 38 are in use. Section 38 
is the broad, level piece of land in 
the ravine east of the conservatories. 
It was platted and offered for sale in 
1903 and some lots sold in it, but in 
1904 the superintendent requested 
that this section be withdrawn from 
sale, which was done. 
Each section contains one or sev- 
eral acres and is completely sur- 
rounded by a main driveway, except 
when one side of it is formed by an 
outside boundary wall or fence. The 
sections are then subdivided into lots 
so that every lot borders on a grass 
or gravel pathway or main road, and 
many of the larger lots have a grass 
pathway all around them. The larger 
lots usually border the main drive- 
ways and because of the curving of 
the roads the outside lots are seldom 
of uniform dimensions. There is no 
such a thing as a “half lot.” The 
smallest lot is what is known as a 
6-grave lot, which contains 150 square 
feet. 
IMPORTANT LITIGATION OVER PATENT MAUSOLEUM 
The matter of the patentability of certain features of 
monument and mausoleum construction has in the past few 
years brought out some interesting court decisions as to what 
cannot be patented, and another no less interesting lawsuit 
involving a patent for mausoleum construction is now be- 
fore the courts in Baltimore.. 
In the celebrated Lockwood case which was in litiga- 
tion for a period of several years, the court decided that 
the mere arrangement of certain members of a monument 
finished in a certain way, was not patentable beicause it 
did not involve anything new or novel, inasmuch as it 
was merely a rearrangement of old forms and methods 
of finishing that had been used before. In the case of 
Tayntor vs. Goetschius, also recently decided by the courts. 
Air. Tayntor’s method of joining the roof stones on which 
he held a patent was similarly held to be unpatentable 
because it was a method of joining stones that had been 
used before, and was not essentially a new invention. 
In the present suit in Baltimore, AI. L. Knight, who holds 
a patent on certain features of mausoleum construction, has 
brought suit against Henry P. Rieger & Co. for building 
a mausoleum involving his patented construction. He claims 
that his invention embodies improved means for obtaining 
ventilation and drainage of crypts, improved methods of 
closing and sealing the crypts and other novel features set 
forth in the patent specifications printed below. The patent 
involves chiefly a system of setting the shelves of the crypts 
in the walls, with “rectangular” openings to form air pas- 
sages. 
Rieger & Co., claim that they did not follow any particular 
piece of work in preparing their plans, but used the methods 
of construction commonly employed throughout the country. 
They maintain that the general plan followed is to build the 
crypts of slate or marble independent of the walls with air 
spaces between the slate and the granite, cutting openings into 
the back of each crypt to admit a circulation of air through 
each compartment. They claim that there is nothing new 
or patentable in the alleged invention and that nearly all of 
the mausoleums constructed to-day would violate the inven- 
tion if it were held valid. 
The case is therefore of considerable importance to the 
trade at large, since if Mr. Knight’s patent is upheld by the 
court, he would doubtless be able to find many other in- 
fringements throughout the country. Mr. Rieger presented 
the matter briefly to the National Retail Monument Dealers’ 
Association at its Cincinnati convention and it was deemed 
of sufficient importance to be referred to a special com- 
mittee, which is to investigate the case and report its 
findings to the executive committee of the association. This 
special committee had not been appointed at the time of the 
closing of the convention but is to be named by President 
Stewart later. 
In order that the definite points involved may be studied 
in detail we reproduce herewith the illustrations in the offi- 
cial specifications for the patent, and the description ac- 
companying them as given in patent No. 979,965, issued to 
Alaurice L. Knight, Decem'ber 27, 1910. The patent specifi- 
cations read as follows : 
Figure 1 represents a perspective view of a mausoleum embody- 
ing my improvements. Fig. 2 represents a longitudinal vertical 
section of the same. Fig. 3 represents a horizontal section of the 
mausoleum. Fig. 4 represents a transverse vertical section on 
the line x — x of Fig 3. Fig. 5 represents a sectional detail view 
of a shutter and its fastenings of one of the crypts or loculi. 
Fig. 6 represents a horizontal section of a window. 
. Similar numerals of reference indicate corresponding parts in 
the figures. 
Referring to the drawings: — The mausoleum has a suitable 
foundation, 1. upon which the side walls, 2 and the front wall, 3, 
and rear wall. 4, are supported. A porch or portico is formed at 
the front by columns, 5, and the frieze, 6, overhangs such porch at 
the front. Gable stones, 7, are supported upon the frieze at the 
front and rear, and have each tw’o tenons, 8, upon each of their 
inclined top-edges. Two roof-stones, 9, of stone, metal or com- 
position, are slantingly supported at their ends upon the slant- 
ing edges of the gable-stones, and have mortises, 10, engaging the 
tenons upon the same. At the eaves, the roof stones or slabs 
are supported upon slanting fillers, 11, which may be integral 
with the frieze-stones. A cap-stone or ridge stone, 12, rests 
upon the inner or upper edges of the roof-stones with its side- 
lips, 13, overlapping such edges. The interior of the mausoleum 
has a floor, 14, of tiles or any suitable or desired material and 
construction. 
A door. 15. is provided in the front wall of the mausoleum and 
opens into a transverse vestibule, 16. extending the full width 
of the structure. A longitudinal corridor, 17, extends rearward 
from the vestibule, between the crypts or loculi, 18, and window 
openings 19 — 19, and 20, are provided respectively at the ends 
of the vestibule and of the corridor. Said windows have each a 
rigid grille, 21, at the outside, an intermediate inwardly swing- 
ing storm-window, 22, and an inner, inwardly-swinging art win- 
dow, 23, of stained or colored glass or otherwise ornamented. 
The crypts or loculi for the reception of the coffins or caskets 
and on both sides of the corridor, are formed from horizontal 
shelves or slabs, 24, preferable of slate or composition, and 
faced at the edges which present to or face the corridor, with 
strips, 25, of marble or other ornamental matferial. The slabs 
or shelves are vertically spaced by end walls or slabs, 26. and 
back walls or slabs. 27, suitably secured to the shelves and to 
each other. The rear edges of the shelves are cut away to form 
rectangular openings, 28, and the back slabs are supported at a 
distance from the walls of the structure and at the edges of 
such openings, so that vertical air-chambers or flues, 29, are 
formed between such walls and slabs. These openings extend 
along the greater portion of the length of the slabs and register 
vertically, so that the air-chambers will be wide and unob- 
structed. Vent-openings, 30, are formed at the lower and upper 
ends of these air-chambers and through the walls, so as to pro- 
vide air-circulation up through said chambers. The back-slabs 
have openings. 31, at their upper and lower edges, communicat- 
ing with the air-chambers or flues, to provide ventilation at the 
top and bottom of each crypt or loculus, and drainage from the 
bottom of the same and said openings extend for more than one- 
half of the length of the back-slabs, so as to afford free ventila- 
tion and drainage to the wide air-chambers,^ and the openings 
register with those of the shelves so as to directly communicate 
with the same. A ceiling-slab or slabs, 32, is supported to cover 
the vestibule and corridor, and one or more rods, 33, are secured 
in the ridge-stone and passed through the ceiling-slab and have 
each an eye, 34. at its lower end. The rod or rods may serve as 
an auxiliary support for the ceiling-slab and serve to support a 
hoisting device for raising the caskets to the upper loculi. The
