Letters Patent No. 112,220, dated February 28, 1871.

IMPROVEMENT IN APPARATUS FOR HEATING .PRQPAGATlNGrBEDS.

The Schedule referred in theee Letters Patent and making put of the name.

To all whom it may concern:

city and'connty of Philadelphia. and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Heating Propagating-Beds;

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specification, in which- Figure I is'a perspective view of myimpi-oved device, showing the furnace or fire-box in'which the fuel is burned, the water-pipes in-which the water is heated, and the 'water-reser'voir over or upon which the cuttings or seeds are placed.

Figure II shows a modification of my devices.

Oorlesponding letters refer-to corresponding parts in bothfigurcs.

In green-houses, propagating-gardens, and other places where plants are propagated, it is of great i'mportanccthat some cheap "and eflectlve devtces should be had bymeans of which the beds inwhich the plants or seeds are placed can be readily warmed; and

My object in the present invention has been to provide such an apparatus 5 and, to this end,

This invention consists in the arrangement of the parts of which it is constructed,'as will be more fully described hereinafter. I

A in the drawing refers to the furnace'or fire-box, which may he of brick or ofany other refractory material, but which, as a matter of economy in fuel, I prefer to make of metal, and, when so made, to provide a water-space, A, upon all of its sides, except the lower or bottom side, which is left open for the escape of ashes, and for the admission bf air for the support of combustion.

The front or some other side of this box is to be provided with doors for the admission of fuel and for the removal; of ashes, as shown MA. A, Fig. I. When made of bricks, or of other, material other than metal, an iron plate may be provided upon which to erect the structure, so as tomake it a portable one, and it may be left open at the top, as shown in Fig. I; I but when made of metal it will be closed at the top, as shown in Fig. II, and'a water-space provided, as there shown. 1 3

A refers to the grates, which may bcof the usual kiudwhen a brick furnace is used, but which, 'when a metal one is used, may consist of a series of pipes communicatingwith the water-space upon the sides of the same, as shown in Fig. I.

B B refer to a pipe or pipes, which maybe arranged, as shown in Figs. 1 and II, according to the kind of furnace to be employed.

. The arrangement, shown in Fig. I, is such that they connect and communicate with v the waterspace in D, from which point they extend to and pass through the furnace A, in the manner shown in Fig. I; or that portion which is within said furnace may consist of a coil.

The water which is contained in the reservoir D flows into these pipes and becomes heated, while in that position,-which is within the furnace, and, as the point at which, in its circulation, it enters the reservoir is above the point where it is taken out to sapply the pipe, it follows that a constant stream will be kept up through such pipe, and that, as a consequence, all the water in the reservoir will be heated to any desired extent.

When a metal furnace is used the circulating-pipes O G will be connected to the water-space, as' shown in Fig. II, and ,thus the entire surface of the box will become heating surface.

0 refers to the smokc-pipe or up-take, which,.when attached to a metal furnace, as shown in Fig. II, may be blanched, as there shown, so that'the heat escaping through it maybe carrledto diflerent parts of the building in which it is placed. By placing damp els in the branches of thispipe the heat. may all be turned in one or the other direction, or it may be divided and a portion thereof directed in both directions at the sometime.

1) refers to thewater-rcservoir, to which the circ'ulating-pipes are connected. It is mounted upon legs, as shown, and is open at its top, so that any box containing the earths of any kind, which constitutes the bed in which propagation is to take place,may be set thereon, and be heated. to any desired. extent by the water which. circulates through it, first on one side of the dividing partition, and then on the other. The depth ofthis reservoir may be suclras to suit the views of the constructor, its dimensions otherwise being such as to render it portable and easily removed from point to point by the men usually in attendance.

It will be apparent that such a device as I have herein described will furnish a cheap and portable means of heating beds for the propagation of plants or seeds, and that it may be placed in any convenient position fora given purpose, and afterwards removed to anyother position in'the same or any other buildaving thus described my invention,

What I claim as new, and desireto secure by Letters Patent, is- I y The arrangement of the furnace A, circulating-pipe or pipes B B, and the water-reservoir D, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
