JOSEPH WV. JOHNSON AND JOHN T. SHERIDAN, OF TORONTO. CANADA,
ASSIGNORS TO J. F. PEASE FURNACE COMPANY, LIMITED, OF TO- RONTO, CANADA.
HEATER AND VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 763,983, dated July 5, 1904.
Application filed June 8, 1903. Serial No. 160,610. (No model.)
To all whmn it may concern.-
.Be it known that we, JOSEPH W. JOHNSON and JOHN T. SHERIDAN, of the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Heaters and Ventilators, of which the following is a specification.
Our invention relates to a heater and ventilator patented in Canada on April 20, 1898, under No. 59,774. In thisapparatus means were provided whereby foul air could be taken out of the room and fresh warm air introduced to take its place, or, if desired, the air within the room could be circulated through the heater until the room was sufficiently warm. In practice it was found that so many dampers had to be manipulated to regulate the heater that they were seldom or never properly set, thus materially interfering with the proper working of the apparatus.
Our object is to devise means for overcoming this objection; and the invention consists, essentially, of the arrangement of the dampers and their operating mechanism whereby one movement of the latter will set the clampers to shut off the fresh-air supply and the vent-flue and open the bottom of the shell of the heater to the air of the room and whereby the reverse movement of the operating mechanism will open the fresh-air supply, open the vent-flue, and close the bottom of the shell of the heater to the air of the room, substantially as hereinafter more specifically described and then definitely claimed.
Figure l is a perspective view of the heater.
Fig. 2 is a sectional elevation of the lower pit door, dampers, smoke-flue, 620.; but as my present invention does not relate to these parts they are not specifically described. At the back of the shell is located a vent-flue C, which flue leads off to some suitable place of discharge and is open at the bottom, as shown, to draw off foul air from the room.
Within the base of the apparatus is located a fresh-air box or boxes I), communicating with the space under the heater, with which communicates the fresh-air fiue E.
The sides of the fresh-air box slope, as indicated particularly in Figs. 1 and 3, and have openings therein controlled by the dampers F, which are hinged at their lower edges at a.
Formed in the shell opposite the dampers F are vertical inlets G, communicating with the interior of the room. It will be noticed that the lower edges of the dampers F'are adjacent to these inlets, so that the dampers when vertical will close these inlets and When inclined, as shown in Figs. 1 and 3, will close the openings from the fresh-air box. Arms H are connected with these dampers and extend inwardly and preferably somewhat downwardly at the back of the heater.
Within the vent-fine is located a damper I, the spindle b of which is at right angles to the hinges of the dampers F. The spindle extends out through the vent-flue and has an arm J secured thereto, provided with a counterbalancing-weight to balance the large portion of the damper which is behind the spindle. Arms K are formed on or connected to this damper. These arms preferably bend somewhat downwardly and, extend through slots in the shell of the heater. The ends of these arms are connected with the ends of the arms H by means of the links L.
From the construction described it follows that when the vent-pipe damper is in the position shown in the drawings the fresh-air inlets to the heater are closed and the inlets from the room are opened, so that the air of the room enters the shell of the heater and passes out at the top, substantially in the manner shown and described in the prior patent referred to. When,- however, it is desired to draw ofi the foul air from the room and admit fresh warm air, the arm K will be moved to turn down the damper I in the vent-flue. The movement of this damper operates, through the arms K, links L, and arms H, to raise the dampers F to close the inlets from the room, thus opening the fresh-air inlets. The foul air in the room is now drawn into the bottom of the vent-pipe and passes away, while fresh air is admitted to the shell of the heater to pass through the same and emerge at the top as fresh warm air to supply the place of the foul air taken off.
It will be seen that by the construction described we insure that the dampers must be in either of two positions, so that the apparatus is bound to work properly either for heating or for heating and ventilating.
The arrows are used in Figs. 1 and 3 of the drawings to indicate the various paths the air may take, according to thepositions of the dampers.
It will be further observed that a single motion changes the dampers, so that the room may be heated or heated and ventilated, as required, thus avoiding the necessity of handling a number of dampers, which formed the drawback of the construction shown and described in the prior patent already referred to.
WVhat we claim as our invention is 1. Ina heater and ventilator the combination of an outer shell having a substantially vertical inlet from the room at its base; a fresh-air box within the base of the shell, having an inwardly-inclined opening therein with its lower edge adjacent to the lower edge of the inlet to the room; a damper hinged at its lower edge and adapted to control either opening; an arm extending inwardly from the said damper; a heater within the shell; a vent-flue;
a damper therein pivoted at right angles to the aforesaid damper; an arm thereon extending through a slot in the shell; and a link connecting the two arms so that the operation of one damper also moves the other, substantially as described.
2. In a heater and ventilator the combination of an outer shell having a substantially vertical inlet from the room at each side of its base; a fresh-air box within the base of the shell, having two inwardly-inclined openings therein, each with its lower edge adjacent to the lower edge of one of the inlets to the room; two dampers, each hinged at its lower edge and each adapted to control one of the freshair inlets and the adjacent inlet from the room; an arm extending inwardly from each of said dampers; aheaterwithinthesaid shell; avcntflue; a damper therein, pivoted at right angles to the aforesaid dampers; arms thereon extending through slots in the shell; and links connecting the said arms with the arms of the aforesaid dampers so that the operation of the Vent -flue damper also operates the others, substantially as described.
