DISK DAMPER CONTROL Filed Feb. 5, 1952 /S/ f7 .Z4 20 mmm E* myzzmv@ AYTORNEY Patented Aug. 29, 1933 f UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to damper or draft controls for furnaces and more particularly to a device for attaching the operating means or chain to the damper in the smoke pipe of the furnace and has for the primary object, the provision of a device of the above stated character Which may be easily and quickly applied to a conventional type of damper without alterations thereto and regardless of the angle occupied by the damper and which is so constructed as to prevent the operating means or chain from feeding thereoff during the use of the device.

With this and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a side elevation partly in section illustrating a damper control for a furnace with an attaching medium between one of the operating chains and the damper in the smoke pipe and constructed in accordance with my invention.

Figure 2 is a side elevation illustrating the.

pulley or disk.

Figure 3 is a detail sectional view illustrating the same and showing the means of connecting the operating chain thereto.

Figure 4 is a fragmentary sectional view illustrating the operating chain mounted for oscillatory movementand connected to the pulley or disk with the latter mounted on the damper of the smoke pipe.

Referring in detail to the drawing, the numeral 1 indicates a conventional type of furnace located within the basement of a building 2 and provided with a smoke pipe 3 controlled by a damper 4. The furnace 1 is also equipped with a draft door 5 and the smoke pipe 3 is provided with a draft door 6. The

draft doors

5 and 6 are connected to operating chains '7 trained over av series of pulleys. The chains are actuated by a conventional type of electrical appliance 8 thermostatically controlled as shown at 9.

The damper 4 consists of a disk removably secured to a shaft 10 journalled in opposite walls of the smoke pipe and provided at one end with a handle 11. A pin 12V extends through the opposite end of the rod l0 and is removable therefrom so that the rod may be detached from both the damper 4 and the smoke pipe. A coiled spring 13 is mounted on the rod between the smoke pipe and the hand piece 11 for the purpose of placing desired tension on the rod to prevent accidental movement thereof. The foregoing description relates to a well known controlling device for dampers and draft doors of a furnace to which my invention is applied.

A disk 14 of circular formation is provided with a centrally located opening 15 to permit the rod 1Q to extend therethrough. One wall of the opening 15 is notched as shown at 16 for the purpose allowing the usual damper plate holding lug to pass through the opening 15 during the mountingof the disk 14 on the rod 10. The disk is provided with pairs of apertures 17 circularly arranged about the opening 15 through which may be threaded wire or similar fastening means 18 which also pass through the handle 11 for attaching the disk to the handle. The disk has formed upon its periphery

marginal anges

19 and 20 forming therebetween a groove for receiving an operating chain 21 actuated by the electrical appliance 8 and trained over a series of pulleys. The flange 19 is provided With openings 22 through which an anchoring medium in the form of a wire orv the like may be passed and also which is passed through the links of the chain forv the purpose of securing the chain within the channel of the disk. The disk when applied to the damper rod 10 has the flange 20 disposed lowermost for the purpose of preventing the chain from feeding'off the disk.y Adisk of this character is applicable to dampers now in use and regardless of the angle the damper is located within the smoke pipe, and due to theV flange 20 projecting beyond the flange 19 any possibility of the operating chain feeding off the disk is entirely obviated.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of my invention, as claimed. v Having thus described my invention, what I claim is:

In combination with a damper supporting rod provided with an apertured handle, a circular disk having a centrally arranged opening to receive the rod prior to the passage of the latter through a smoke stack and its application to a damper plate in said stack, said disk having apertures arranged around the opening, a flexible element threaded through the apertures and the apertured handle, flanges formed on said disk and receiving therebetween an operating means, one of said flanges projecting beyond the other flange to prevent the operating means from feed-v ing off the disk, and a securing means between one of the flanges and the operating means.
