PROVISIONAL SPECIFICATION.
An Improved Drain for Stable Stalls.
I, MARTIN LOGAN of 203, East 77 Street, in the City County and State of New
York, United States of America, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
==
My invention relates to an improved drain for stalls which is neat simple and
convenient capable of being easily applied, which will not readily become clogged
and foul, and which can be expeditiously cleaned.
The drain is constructed of a base plate preferably of metal of rectangular cross-
section provided at two sides and at one end only with a marginal flange and
having a series of ribs upon its upper face. Each rib has in its upper face a
longitudinal, preferably U-shaped or semicircular groove forming gutters and the
outer faces of the ribs are preferably perpendicular so as to furnish a series of
channels rectangular in cross-section and as the flanges of the body plate are at the
sides and one end only of the latter, both the channels and the gutters are closed at
one end and open at the other. The side flanges are virtually ribs and have gutters
produced therein. A tread bar is inserted in each channel, the said tread bars
being somewhat T-shaped in cross-section, comprising a head which is above and
rests upon the ribs and a narrow portion which enters a channel between the ribs.
The drain is preferably placed at or near the centre of the stall and the flooring of
the stall is cut away or so laid as to form an opening for the reception of the drain.
The flooring at the inner end of the opening is provided in its under face with a
rebate, and a corresponding rebate is formed in the upper face of each tread bar at
its inner end. The outer end of each tread bar that is, the head section of the bar,
is preferably bevelled. When the drain is placed in the opening in the floor of
the stall, the upper edge of the flanged portion of the drain body is preferably
made to engage with the under face of the boards forming the side walls of the
opening and the height of the tread bars is such that their upper faces will be
practically flush with the upper surface of the floor when the drain is in position.
The rear flange of the drain body extends beneath the rebate in the floor so that
the rebate portion of the thread bars will engage with the rebate in the floor and
form a perfect lock joint.
In placing the drain in the stall the body of the drain is ordinarily carried over
the inner edge of the main drain of the stable and the tread bars are held in position
by the cover of the main drain, which is bevelled at one side to rest upon the bevelled
surface of the tread bars. Thus the upper face of the cover of the main drain may
be flush with the upper faces of the tread bars but the gutters are led directly into
the main drain below its cover.
I do not confine myself to the exact formation of the walls of the channels, as
the walls of said channels may be made to flare or may be bevelled either in the
direction of the upper or the lower portion of the base; but whatever the cross-
sectional contour of the channels may be, the narrow portions of the tread bars
are given a like cross-sectional shape. An elastic material may be packed beneath.
the tread bars, or the elastic material may be otherwise disposed to give more or
less spring or yielding movement to the bars. The bars, which would preferably be
of wood, may be locked in the channels in such manner as to be moved laterally only
therefrom. As a modification, a mat may be made for the stalls or for use in other
places, in which event a suitable lock for the tread bars is provided located either

page_text: at the side or at the end of the base, and the thread bars may be made to extend
transversely, instead of longitudinally, of the base.

An Improved Drain for Stable Stalls.
I, MARTIN LOGAN of 203, East 77 Street in the City County and State of New
York, United States of America, Manufacturer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to an improvement in drains for stalls, and the object of
the invention is to provide a neat simple economic and convenient device capable
of being easily applied to any stall and which will thoroughly drain the same. A
further object of the invention is to provide a drain which will not readily become
clogged and foul and one that can be expeditiously cleaned if clogged. Another
object of the invention is to construct a drain which will not be injurious to the
animals feet and which will be entirely free from nails, screws, sharp bars, or any
surface liable to do damage and wherein also the tread bars of the drain may be
quickly and easily removed from the body of the drain and both cleaned and the
bars replaced without in the least injuring the floor of the stall or removing any
portion of the floor or fixtures of the stall.
The invention consists of the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a perspective view of a stall illustrating the invention applied
thereto.
Figure 2 is a transverse section through a drain and a portion of the floor of a
stall, and
Figure 3 is a longitudinal section taken practically on line 3-3 Figure 2.
Similar figures and letters of reference indicate corresponding parts in all the
views.
.
The base A. of the drain is preferably constructed of metal, is essentially
rectangular in cross-section, and consists of a plate provided at two sides and at
one end only with a marginal flange 10 and a series of ribs 11 produced upon the
upper face of the plate, preferably longitudinally thereof. Each rib is provided in
its upper face with a longitudinal preferably U-shaped or semicircular groove
forming thereby gutters 12, and the outer faces of the ribs are preferably made
perpendicular creating thereby a series of channels 13 essentially rectangular in
cross-section, and as the flanges of the body plate are at the sides and at one end
only of the latter both the channels and the gutters are closed at one end and open
at the other. The side flanges are also virtually ribs and have gutters produced
therein. In each channel 13 a tread bar 14 is inserted, the said tread bars being
somewhat T-shaped in cross-section, comprising a head which is above and rests
upon the ribs and a shank which enters a channel 13 between the ribs, as is best
shewn in Figure 2.
The drain is preferably placed at or near the centre of the stall and the
flooring B of the stall is cut away or so laid as to form an opening 15 for the
reception of the drain. The flooring at the inner end of the opening is provided
in its under face with a rebate 16, and a corresponding rebate 17 is formed in the
upper face of each tread bar at its inner end. The outer end of each tread bar,

page_text: in
that is the head section of the bar, is preferably bevelled as illustrated at
Figure 3. When the drain is placed in the opening 15 in the floor of the stall,
the upper edge of the flanged portion of the drain body is preferably made to
engage with the under face of the boards forming the side walls of the opening and
the height of the tread bars is such that their upper faces will be practically flush
with the upper surface of the floor when the drain is in position. The rear flange
of the drain body extends beneath the rebate 16 in the floor so that the rebate
portion of the tread bars will engage with the rebate in the floor and form a perfect
lock joint as is best shewn in Figure 3.
In placing the drain in the stall, the body of the drain is ordinarily carried over
the inner edge of the main drain D of the stable and the tread bars are held in
position by the cover D' of the main drain which is bevelled at one side to rest
upon the bevelled surface a of the tread bars. Thus the upper face of the cover of
the main drain may be flush with the upper faces of the tread bars but the gutters 12
are led directly into the main drain below its cover.
It is obvious that any matter collecting in the gutters will readily find its way
into the main drain or culvert and that when it is desirable to remove the tread
bars in order to clean the gutters should they become clogged it is simply necessary
to remove the cover from the main drain or culvert, whereupon the inner ends of
the tread bars may be drawn from beneath the flooring and lifted vertically
upward out of engagement with the base. The entire surface of the base
will then be exposed to view and may be readily washed out or otherwise
cleansed.
I desire it to be distinctly understood that I do not confine myself to the exact
formation of the walls of the channels 13 as the walls of the said channels may be
made to flare or may be bevelled either in the direction of the upper or the lower
portion of the base; but whatever the cross-sectional contour of the channels may
be the shank sections of the tread bars are given a like cross-sectional shape. I
further desire it to be understood that any elastic material may be packed around
the shank sections of the tread bars or placed beneath said bars, or the elastic
material may be otherwise disposed to give more or less spring or yielding move-
ment to the bars. It is also obvious that the bars may be locked in the channels
in such manner as to be moved laterally only therefrom. The tread bars may be
made of any suitable or approved material, but wood is preferred.
As a modification a mat may be made for the stalls or for use in other places, in
which event a suitable lock for the tread bars is provided located either at the
side or at the end of the base and the tread bars may be made to extend
transversely of the base instead of longitudinally thereof if in practice it is found
desirable.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A drain comprising a base plate provided with a series of gutters and tread
bars of softer material than the base plate removably located between the gutters,
as and for the purpose specified.
2. A drain consisting of a base plate provided with a series of gutters and tread
bars removably located between the gutters which bars extend above the upper edges
of the gutters, as and for the purpose set forth.
3. A drain for stalls, consisting essentially of U-shaped gutters placed between
longitudinal slats or tread bars in the stall floor and connecting with a cross or
main drain and means, substantially as described, for locking the slats or tread bars
and gutters in position, as and for the purpose specified.
4. In a drain, the combination, with a base flanged at its sides and at one end and
provided with a series of alternately arranged gutters and channels and slats or
tread bars located in the channels of the base having their ends engaging with the

page_text: end flange of the base and provided with a rebate section in their upper faces adapted
to engage with the rebate section of flooring, of a main drain or culvert crossing
the flange end of the base the cover of which main drain or culvert engages with
the tread bars over the gutters and serves as a lock for the bars, as and for the
purpose specified.
