PERAMBULATOR Filed Jan. 26, 1955 Patented May 14, 1935 UNITED STATES PATENT OFFICE 2,001,343 PERAMBULATOB Martha Fehre, New York, N. Y. Application January 26, 1933, Serial No. 653,573

1 Claim.

This invention relates to improvements in perambulators, or baby carriages, and particularly to a vehicle of this character having means for heating the handle portionsof the frame. Its principal object is to provide a form of equipment in combination with the vehicle structure which will, when the carriage is in motion, generate sufficient heat to the handle grips so that the hands of a person grasping the same will be comfortably warmed thereby.

Modern methods as applied to the care of infants require that the child shall be kept in the open air for long periods each day. This is generally accomplished by wheeling the child about in a vehicle of the class above designated. Now, several hours spent in pushing such a vehicle about on a day when the temperature is below freezing, is a very uncomfortable procedure under ordinary circumstances, and in many cases the person attending the infant would be tempted, or forced by reason of cold hands to shorten the period of airing, or to postpone it until another day; all of which is bad for the child whose health is endangered by this lack of proper care.

It is the purpose of this invention to provide a means for maintaining the handle grips at a comfortable temperature and to accomplish this by the use of a simple and inexpensive apparatus installed on the frame of the carriage. This apparatus is automatic in action and requires practically no care or attention other than occasional lubrication.

The foregoing objects and features and other advantages of the invention are fully set forth and explained in the following specification and claim, and illustrated in the accompanying drawing, in which:

Fig. 1 shows a side view of a baby carriage with the apparatus attached.

Fig. 2 shows an enlarged fragmentary section on the line 2-2 of Figure 1. 3

Fig. 3 shows a further enlarged cross section on the line 3-3 of Figure 2.

Referring now to Figure 1 of the drawing; an electric generator I is shown mounted on the axle ll of the carriage I2. This generator has a gear l3 which is in mesh with a drive gear II attached to the wheel l5 of the carriage. Current is produced when the carriage is moved along in the usual manner. The generator is then rotated by the gear M. The current passes upward along the wire l6 which is, preferably, within the handle bars l1.

Referring now to Figure 2, the grip elements l3 5 are made of any suitable material, such as thin metal or the like, oxidized to give a desirable color. These grips are sustained by the cross rod i9 having the nuts 20 at its extremities.

Within the grip elements and supported on the 10 rod I9 is an insulator 20 of porcelain or similar material-see Figure 3. A channel 2| has perforations 22 and within the channel a resistance coil 23 is positioned. This coil is in circuit with the positive wire l6see Figure 2and the negative wire 24 which leads back to the generator. A switch 25 is conveniently placed as shown so that the current may be shut off when desired. Air spaces 26 extend along the interior of the grip elements and distribute heat received through the perforations 22.

While the invention is shown and described in its preferred general form; it may be subjected to minor changes in detail without prejudice to the principle involved, and it is therefore broadly claimed within the spirit and scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent of the United States, is as follows:

In a device of the class described, the combination of a heating unit with a carriage handle, and comprising grip elements, a rod supporting the latter, an insulator mounted on said rod and being made with two upwardly projecting flanges at its top, said flanges forming a channel between themselves and being provided with perforations in their longitudinally extending surfaces, a resistance coil disposed in said channel and serving as a positive wire, and with a, negative wire co-acting with said resistance coil; the insulator being of a size relative to the gripping elements so as to form spaces therebetween adapted to co-operate with the perforations in the flanges leading to said channel for the conveyance of heat from the resistance coil, disposed in the latter, to the gripping elements, and a switch for controlling the heating element.
