Improvements in Hods for Carrying Mortar, Bricks, and other
materials.
I, CONRAD CARLSON of No. 183 Sixteenth Street in the City of Brooklyn in
the County of Kings and State of New York, United States of America, Engineer,
do hereby declare the nature of this invention to be as follows:-
.
My invention consists in the construction of hods for carrying mortar and
bricks, the objects of which are to protect the side boards at the open end from
battering up and splitting by the concussions to which they are subject in dumping
the contents, also to prevent the sides from warping through the effects of the
inside exposed to wet and the outside being dry, also to prevent leaking through
the bottom joint, also to secure the parts more effectually at the closed end, also to
provide better means of suspending them on the elevator chains, also to provide
for more effectually securing the handle socket to the sides, and the handle in the
socket, and also to provide strengthening stays of the side bars of the handle
socket in an arrangement affording simple and ineffaceable distinguishing marks of
ownership for protection against piracy which is very common amongst the users
of hods.

For the protection of the sides of the box at the open end both from battering
and warping I provide. a V shaped skeleton frame of malleable iron consisting of
two parallel side bars located about the thickness of the said sides apart, or a little
less and joined together at the ends and at suitable intervals along by cross webs,
both the bars and the cross webs, or it may be the cross webs only, being tapered to a
"knife edge
on one edge to drive on to said ends of the sides and force the cross
webs into the wood, and the side bars on to the sides of the ends, and thus provide
iron clad ends of great durability in resisting the shocks to which the hods are
exposed when said ends are let fall on the mortar board, or the edge of a plank in
discharging the contents. This frame is very rigid transversely, and effectually
prevents the sides of the hod from warping by the effects of the wet mortar on the
insides whilst remaining dry on the outside.
To the other end of the hod I apply an endless iron band extending all around
the rear end including the head of the end board extending above the sides, and
also around a piece attached to the bottom for the saddle which is wider than the
bottom of the box so that for a considerable distance up the sides said band ranges
at considerable distance from the sides, and in this locality I put a tightening bolt
through the band and the sides and end board, which by drawing the band into
the angles secure the band without other fastening and binds all parts firmly
together.
To prevent leaking through the joint at the angle of the two sides, I make the
joint at said angle, which is the bottom of the hod, by bevelling the sides so as to
meet in a vertical plane and saw a kerf in each bevelled edge, the kerfs of the two
edges being coincident, and insert a thin metal strip extending from end to end
which makes a water tight joint and prevents leaking on the shoulder of the carrier.
Besides packing the joint the metal strip affords a material protection against a
common practice among hod carriers of appropriating to themselves the hods of
elevating companies, which are generally made longer than those which are to be
carried up, and disguising them by sawing them short.
For better means of suspending the hods on the elevator chains used to elevate
the hods I construct the beforementioned side protecting frame, with laterally
projecting angle or hook ears on each side, adapted to hook on to the rungs or into
the links of the chains preferably providing each side of the frame with two or

page_text: more forms of these hook ears for different forms of chains. For one form of chain
I arrange the said projecting hook ears flush with the lower end of the frame and
make a notch in the lower edge of the wood behind the ears to permit the hook ears
to drop and engage the rung.
For another form of chain I construct said frame with other laterally projecting
ears farther up the sides of the frame where pins have commonly been fastened
separately to the sides of the hod for lodging in hook links of the chain, the
advantages of thus providing these hook ears is the simpler method of constructing
and applying them by producing them integral with the frame casting so that they
are applied by the application of the said frame.
In the common arrangement of the metallic handle socket attached to the bottom
of the box so as to project downward to receive the handle or staff, the branching
arms extending upward along each side and attached thereto interfere greatly
with the side of the head of the carrier when resting on the shoulder. I therefore
construct these branches in much wider divergence from the top of the socket to
provide ample space thereat and avoid such hindrance, above which I curve the
branches inward to prevent separating them too much at the top, and then to
prevent them from working slack by straightening I cast the branches with spurs
or studs on the side bearing against the sides of the box to be driven into the
wood and thus seoure the branches against straightening, and in addition I will also
provide a cross bar between said branches sufficiently low in the crotch to avoid
interference with the side of the head of the carrier, and I will also construct this
cross bar in the form of the initial letters of the name of the owner or manufacturer
for a distinguishing mark of ownership.
For better security of the staff or handle in the handle socket I make a notch in
the bottom of the box above and coincident with the socket and fit the upper end
of the staff to enter the hole, and I construct the socket with projections inside
inclined on one side to allow the handle to be driven in but on the other side having
"biting" edges entering the wood to prevent the handle from being pulled out.

Improvements in Hods for Carrying Mortar, Bricks, and other
materials.
I, CONRAD CARLSON of No. 183 Sixteenth Street in the City of Brooklyn, in
the County of Kings and State of New York, United States of America, Engineer,
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 consists in the construction of hods for carrying mortar and bricks,
the objects of which are to protect the open end from battering up and splitting by
the concussions to which it is subject in dumping the contents; also, to prevent the

edges being coincident, and insert a thin metal strip extending from end to end.
which makes a water tight joint and prevents leaking on the shoulder of the

Besides packing the joint the metal strip affords a material protection against a.
common practice among hod carriers of appropriating to themselves the hods of
elevating companies which are generally made longer than those which are to be

page_text: hereinafter fully described reference being made to the accompanying drawings in
which :-
Fig. 1 is a side elevation of my improved hod.
Fig. 2 is an elevation of the open end of a hod hung on a chain.
Fig. 3 is an elevation of the closed end.
Fig. 4 is a side elevation of the hod hanging on the so called "ladder-chain
elevator" by the contrivance which I provide for the purpose.
"
Fig. 5 is a side elevation of said hod hung on the so called "hod elevator chain
of. a different construction by another contrivance which I also provide for such
.elevators.
Fig. 6 is an elevation of part of the closed end, on an enlarged scale, to
illustrate more fully the contrivance for preventing the joint of the two sides from
leaking.
Fig. 7 is a sectional elevation of part of the skeleton frame for protecting the
sides from battering up and from warping taken on line xx, of Fig. 2 and drawn
to a larger scale.
Fig. 8 is a transverse section of part of said frame on line y y Fig. 7.
Fig. 9 is an elevation of one of the parts of the handle socket and its side bars,
showing the inside thereof.
Fig. 10 is a side elevation of portions of the hod with the front portion of the
handle socket and its side bars removed.
For the protection of the sides a, of the hod at its open end both from battering
and warping, I provide the V shaped skeleton frame of malleable iron consisting
of two parallel side bars c, located about the thickness of the sides a, apart, or a
little less and joined together at the ends and at suitable intervals along them by
the cross webs d, both the bars and the cross webs being wedge shaped in cross
section, as shown in Figs. 7 and 8, and drive it on to said ends of the sides, forcing
the webs d, into the wood and thus provide substantial iron clad ends of great
durability in resisting the shocks to which the hods are exposed when said ends are
let fall on the mortar-board or the edge of a plank in discharging the contents.
This frame is very rigid transversely and effectually prevents the sides from
warping by the effects of the wet mortar on the inside, while remaining dry
⚫ outside.
I construct it with the laterally projecting angle ears h, one on each side, flush
with the lower end, and make the notch i, in the wood behind them, and thus
provide for hooking the hod on to the rungs j, of the ladder chain k at two points
sufficiently distant from each other to prevent the hod from swinging sidewise and
sometimes wrenching off, to which it is subject as commonly made, with only one
hook at the centre for so hooking on the rungs. I also construct it with other
laterally projecting ears 1, farther up the sides of the frame (where pins have
commonly been fastened to the sides a, of the hod) for lodging in the hook links m,
of another form of elevator chain, as n, frequently used. The advantages of this
arrangement are the simpler method of providing these ears, which are cast
together with the frame, and they are more substantial and I also construct, said
frame with an integral arm a, extending from each outside bar e backward and
obliquely downward along and so as to have bearing contact with the sides c to a
suitable distance back of the end and near the lower edge to receive a fastening
bolt y to prevent the frame from being thrust off by the shocks.
I make the joint o between the two sides a by bevelling them so as to meet in a
vertical line and saw a kerf at right angles thereto in each edge and insert a thin
metal strip p, extending from end to end which makes a water tight joint and
prevents leaking on to the shoulder of the carrier. At the rear end I apply an
endless band of iron s extending all around including head z, and insert the bolt
to bind all parts together. The V frame secures said joint at the open end. It
will be seen that with the ends of the two sides bound together by the frame and
"band, and the packing strip fitted in the kerfs of the meeting edge the nailing of
the edges is not required, for although the joint inay open slightly by the effect of

page_text: wetting and drying it will not leak in consequence of the packing strip. By
dispensing with the nails much splitting caused by them is avoided.
Besides packing the joint tight the metal strip p, affords a material protection
against a common practice among hod carriers of appropriating to themselves the
hods of hod elevating companies, which are longer than the hods that are to be
carried up, and disguising them by sawing them short.
At the present time hods having the metallic socket u for the handle c¹ have the
plain side bars or branches v extending up the sides a, without a cross stay between
them, which, though not a very essential requirement, is useful for greater strength;
but besides the application of such a stay for greater strength I propose to utilize
it also for a distinguishing owner's mark by constructing it in the form of initial
letters, as w, or any other distinctive mark, made integral with the branches, so
that it cannot be effaced without showing the mutilation incident to its reinoval.
And I make said side bars to extend up and hook over the edges of the sides a and
provide said side bars or branches u with spurs or studs a' to be driven into the
wood when the side bars are applied as a further means of preventing the side bars
from displacement by straightening and elongating. represents the spurs in the
socket u for securing the handle. represents the hole or notch in the bottom
of the hod coincident with the socket for reception of the end of the handle.
The common practice of marking is by branding the sides; but the brands can
be readily scraped out so as to leave no sign.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
claim is :-
1. The combination, with the sides of a mortar-hod, of the V shaped metallic
re-enforcing and stiffening frame consisting of side bars and integral cross-webs
driven on the ends of the sides substantially as described.
2. The combination with the sides of a mortar-hod, of the V shaped metallic
re-enforcing and stiffening frame consisting of side bars and integral cross-webs
driven on the ends of the sides, and the laterally projecting integral arms of said
frame for hooking on the elevating-chains substantially as described.
3. The combination with the sides of a mortar-hod, of the V shaped metallic
re-enforcing and stiffening frame consisting of side bars and integral cross-webs
driven on the ends of the sides, and the laterally projecting integral ears of the
side frame, flush with the lower end of said frame, for hooking on the elevator
chain, said hod having the notch in the bottom behind said frame substantially as
described.
4. The combination with the sides of a mortar-hod, of the V shaped metallic
re-enforcing and stiffening frame consisting of side bars and integral cross-webs
driven on the ends of the sides, and the rearwardly extended arms along the sides a,
and bolted thereto, substantiaily as described.
5. The combination with the sides a, having the bevelled and kerfed meeting
lower edges, of the flat metal packing strip inserted in said kerf, the V frame
fastening the sides together at the front end, and the metal band and bolt
binding said sides and the head together at the rear end, all substantially as
described.
6. The combination with the sides of a mortar-hod, of the handle socket made
in two parts, each having side bars or branches extending up said side C and the
spurs or studs to enter the wood, also the cross-stays, and the bottom of the hod
having the hole or notch for reception of the end of the handle substantially as
described.
