JAMES L. HAMILTON, F GR'AND JUNCTION, COLORADO, ASSIGNOR OF ONE-FOURTH TO W. R. HAINES AND ONE-FOURTH T0 CHARLES VAN HOOSEBEKE, BOTH OF GRAND JUNCTION, COLORADO.

Application filed January 2, 1909.

' b all whom it may concern:

Be it known that I, JaMEs HAMILTON, a citizen of the United States, residing at Grand Junction, county of Mesa, and State of Colorado, have invented certain new and useful Improvements in Orchard-Heating Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 0 in the art to which it appertains' to make and use the same, reference being had tothe accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

5 My invention .relatesto improvements in orchard devices, my object be ng to rovide an article of this characterjwhichs all be well adapted for use in raising the'temperature sufficiently in the vicinityl'o'f orchards, to gardens and in all localities containin vegetation, to prevent injury thereto by rost.

My improved'device comprises a receptacle for liquid fuel, as'oil, in which is located j ;requ1red,- itf s often impossible to obtain an adjustable partition or'bulk head, whe re by the receptacle maybe divided into two compartments having any desired relation to each other as regards volume or capacity.

t On one side of the partition the liquid fuel is lighted and this com artment forms a combustion chamber; while on the opposite side the liquid fuel constitutes a source of supply for the combustion com artment. While the partition fits quite close y within (the receptacle, the oil will pass between its adjacent edges and the walls of the receptacle and maintain the liquid fuel at the same level in both compartments.

My improved device is exceedingly advanta eons for the purpose stated, from the fact that by simply ad usting the partition separating the two compartments, an increase in heat from each individual device may be obtained, since by the movement of the partition the size of the combustion chamber or compartment is enlar ed, exosing an increased surface area of t e burnmg liquid. It is evident that the fuel receptacle may be made of any desired size whereby a suflicient quantityof oil may be placed therein to last an entire season.

adjustment of the partition a small quantity of liquid fuel may be ex osed, or a considerable'quantity, as desire while with other devices i tended for use in heating orchards, so far as -m aware,"'in order to increase the Specification of Letters Patent.

same, showin By the ORCHARD-HEATING DEVICE.

Patented Nov. 23, 1909. Serial No. 470,546.

heating capacity it is necessary to add additional heating devices, since each device is a unit, and its heating capacity cannot be increased. This is believed to be true so far as all devices of this character for the bunk--61) ing of liquid fuel are concerned.

he facility with which my device may be regulated for the purpose or increasing the heat, is exceedingly important, since it often .happens that there is a sudden fall oftem- 5 perature, and under ordinary circumstdn ces, or where other heaters are used, there would not be sufficient time to place additional heaters in the orchards until the damage had resulted; while with my device a single individual can quickly adjust the partition of a great manyof; these devices, and thus immediately increase the fire or heating ca- ;pacity of each device. 'This'is' also very important for the reason that during the period when devices of this character are needed, it is usually difiicult to obtain workmen, and where :a considerable number are them. With my device no difliculty of this so kind can arise, for the reason heretofore stated.

'Having briefly outlined my im roved device, I will proceed to describe t e same in detail, reference being made to the accomas,

panying drawing in whichis illustrated an embodiment thereof.

In this drawing, Figure 1 is a perspective view of my improved orchard heater. Fig. 2 is a. vertical longitudinal section of the 9 the cover and partition or bulk head ad]usted for use, the receptacle being provided withliquid fuel. Fig. 3 is a cross section of the device taken on the line 3-3 Fig. 2. Fig. 4 is a perspective view in detail of one form of the partition or bulk head. Fig. 5 is a similar view of another form of said partition.

The same reference characters indicate the same parts in all the views. 10

'Letthe numeral 5 designate a receptacle ada ted to contain liquid fuel, as oil, which is esignated in Fig.2 bythe numeral 6. This receptacle is provided nearits top with perforations 7, which preferably extend en- 10 tirely around the receptacle, that is to say, on all four sides thereof. As shown in the drawing, one extremity of the receptacle has its side and end walls formed somewhat higher than the corresponding walls of the 1 opposite portion. The part having the higher walls may be designated the forward end of the device, or that where the fuel is to be lighted, and which will constitute the combustion chamber. This portion of the device is provided with additional perforations 7 formed in the upper portion 8 of the side and end walls. Located within this receptacle is the partition or bulk head 9, which, if of the form shown in Figs. 2 and t, is preferably formed hollow, as shown at 10, and composed of tire clay, or other material adapted to resist the action of the heat in the combustion chamber. This partition may be of the construction shown in Fig. 5, in which the body part is composed of a metal plate 12 having side wings 13, an as bestos member 14 being applied thereto to prevent the heat from passing readily from the combustion compartment to the contents of the receptacle on the opposite side of the partition. This asbestos member occupies a position in contact with the metal plate 12 and between the side wings 13. It is evident that many different forms of construc tion for this partition may be employed. Any suitable form may be used that is adapted to prevent the too rapid travel of the heat from the combustion chamber to the chamber containing the source of fuel supply.

It is evident that it is not desirable that the li uid fuel in the reserve chamber should be an uly heated. It will, however, be kept warm or of sutlicient temperature to cause it to flow readily, thus puttin it in proper condition for passing around the partition into the combustion chamber with sutIicient freedom to maintain the level of the fuel the same in both compartments.

Whichever style of partition is employed it is made to fit the opposite side walls the receptacle 5, and is readily slidable therein. The side walls of this receptacle are preferably inclined, whereby the receptacle is widest at the top and diminishes in width toward the bottom. By virtue of this construction, a partition whose opposite edges fit between the two side walls will be sure to maintain an n right position at all times. When formed 0 fire clay, or other similar material, it is important that the partition or bulk head should be hollow or rovided with an air chamber which is Well a apted to prevent the passage of Heat through the partition. It is evident that in choosing material for this bulk head or partition, those substances possessing a high degree of heat conductivity should be avolded.

My improved device is further provided with a cover 15, which is slidably mounted between the side walls of the receptacle. The upper edges of these walls are turned inwardly, as shown at 16, to form guide ways for this cover, whose forward portion rests when the cover is properly adjusted. \ttI- isters with the chamber of the hollow bullc head. hen the cover is so adjusted, a tool (not shown), of any suitable character may be inserted in the openin; 18, whereby it is caused to protrude into the chamber 10,

whereby the cover and bull: head or parti,

tion may be moved back and forth simul taneously.

From the foregoing description, the use of my improved device will be readily under stood. Any desired number of these devices may be located in the orchard or other locality needing protection from frost. The devices may be located at such intervals as desired. Each receptacle 5 should be sup plied with a quantity of fuel oil. In the first instance the partition 9 should be adjusted to expose any desired surface area of the oil, according to the amount of tire required. If it is only desired to produce a small quantity of heat, the partition is moved to expose a corresponding surface of the oil, while if a greater fire should be required, the partition is readily adjusted to expose a greater area of the liquid fuel within the combustion chamber, or forward extremity of the receptacle. When this is done the oil within the exposed compartment of the receptacle is lighted, the cover 15 being adjusted so that its forward extremity shall rest upon the top of the bulk head or partition.

The function of the perforations 7 at the left of the partition is to allow the escape of any gas that may be formed, due to the heating of the oil, or liquid fuel, within the compartment at the left of the partition, refer ring to Figs. 1 and 2. These perforations are therefore considered an element of safety to prevent possible explosion, due to the formation of gas by heat conducted from the combustion chamber. They may be used or not, as desired.

Having thus described my invention, what I claim is:

1. A heating device, for the purpose stated, comprising a receptacle for liqu d fuel, a partition or bulk head located therein dividing the receptacle into two compartments, the said partition being adjustably mounted in the receptacle and arranged to permit; the'flow of fuel. from one side of the partition to the other, for the purpose set forth.
