1934- w. SHAKESPEARE, JR 3 REMOTE CONTROL DEVICE I Filed Feb. 9, 1933 Patented Feb. 20, 1934 UNITED STATES PATENT OFFICE REMOTE CONTROL DEVICE William Shakespeare,

Jr., Kalamazoo, Mich.,

assignor to Shakespeare Products Company,

Kalamazoo, Mich.

Application February 9,

12 Claims.

The main object of this invention is to provide a remote control which is well adapted for furnaces, is very easily installed, effective and noiseless in operation and not likely to get out of repair or become inoperative.

A further object is to provide a structure having these advantages, which is very economical in its parts.

Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary view of a furnace installation equipped with my improved remote control, the parts associated with the control being shown mainly in conventional form.

Fig. 2 is a front elevation of the control, the transmission elements being partially broken away.

Fig. 3 is a rear elevation, the attached ends only of the transmission elements being shown.

Fig. 4 is an enlarged sectional view on line 4-4 of Figs. 2, 3 and 5.

Fig. 5 is an enlarged sectional view on line 55 of Figs. 2, 3 and 4.

Fig. 6 is an enlarged detail section on a line 66 of Fig. 3.

Fig. '7 is a front elevation of the clamping member.

In the accompanying drawing, 1 represents a portion of a building, 2 a hot air furnace having inlet or draft damper 3 and check damper 4 in the smoke flue 5.

This improved control device comprises a cylindrical casing or housing member 6 having a front wall 7 with a central opening 8 therein. This casing is preferably a sheet metal stamping although it may be molded of bakelite or like material if desired. The casing is provided with attaching ears 9.

The front wall '7 has an inwardly struck or extending annular bead 10. The edge of the opening 8 is preferably flared slightly outward to provide a seat for the handpiece 11 which constitutes a cover for the opening. This handpiece is preferably provided with ear-like grip portions 12 at each end and with a pointer 13. Within the casing is a drum consisting of a grooved rim 14 and web 15 having a central flanged opening 16, the flange extending outwardly centrally of the opening 8 in the casing.

The handpiece is provided with a central face 1933. Serial No. 655,887

plate 117 having lugs 17 which extend through The with its web in engagement with the annular bead 10. The face plate is adapted for use as a name plate and conceals the slots 118 in the handle.

The transmission elements 19 are formed of resilient wire and are connected to the drum by providing inturned ends 20 which are arranged through holes 21 in the periphery of the drum. These ends are also passed through the instruck loop or strap 22 on the web disposed in alinement with the holes. The periphery of the drum is grooved for receiving the wires. The wires tend to straighten out and thereby hold themselves in frictional engagement with the casing and do not hug the drum. The wires also constitute spring members acting to hold the drum centered and in adjusted position. These transmission elements are oppositely disposed around the drum and passed through holes in the casing, the holes not being illustrated.

The drum is provided with a pair of stops 23 coacting with a stop 24 on the clamping member 124 to limit the rotative movement of the drum. The wires 19 are the transmission elements of Bowden tube devices indicated generally by the numeral 25, that is, the wires reciprocate in bendable sheaths which constitute supports for the wires, as is well understood in the Bowden type of transmission.

The inner ends of the sheaths 25 are clamped to the Wall by the clamping member 124 which has a screw opening 126 registering with the opening of the lower attaching ear 9 or the passage of the attaching screw 127. The stop 24 passes through an opening 128 in the wall of the casing 6 so that by removing the clamping member 124, the drum may be rotated as desired within the casing during installation.

One of the transmission elements in a furnace installation leads to the draft damper 3 and the other to the check damper 4 so that when the drum is rotated in one direction, counter-clockwise in the installation illustrated, the draft damper is opened and the check closed. Rotation in the opposite direction or clockwise direction reverses the opening and closing of these dampers. I

This type of device is very desirable where it is desired to transmit power a considerable distance and indirectly, or to non-alined parts. My improved control device is very simple and economical in its parts and the parts'are easily assembled. The device is easily operated and at the same time there is sufiicient friction imparted by the transmission elements coacting with the drum and casing to hold the drum in its adjusted position, even when against considerable load. This avoids the use of springs or detents and locking means.

I have illustrated and described my improvements in an embodiment which I have found very practical. I have not attempted the illustration of certain embodiments and adaptations which I contemplate, as it is believed that this disclosure will enable those skilled in the art to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: V
