SPRING SEAT.

This invention relates to spring seats for farm machinery, such as tractors, wheeled cultivators and the like, and has for its principal object to provide a means whereby the operator of the machinery may obtain a maximum comfort occupying the'seat.

Another important object of the invention is to provide a spring seat of the above mentioned character wherein means is provicled for limiting the upward movement of the seat, as well as limiting the downward movement thereof.

Another important object of the invention is to provide a spring seat of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing, forming a partof this specification, and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of the spring seat embodying my invention.

Figure 2 is a top plan View thereof with the seat removed, and

Figure 3 is a sectional View, taken approximately on the line 33 of Figure 1.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, thenum-erals 1 and 2 designate a pair of vertically spaced horizontally arranged plates, each of which is of substantially rectangular design, the lower plate 2 being adapted to be secured on the upper end of the seat supporting beam 3 by any suitable fastening means, such as is shown at l. The upper plate 1 is adapted to be secured on the bottom of the usual seat 5, in any suitable manner.

Disposed between the spaced upper and lower plates are the helical coil springs (3. The springs are arranged on each of the sides of the plate, one spring being provided for each of the sides and the same being arranged centrally, or intermediate the ends, in a manner as more clearly illustrated in Figures 1 and 3 of the drawing.

It is off 'course to be understood that the diagonally arranged coil springs are arranged at each of the corners of the plate, in the manner as shown in the drawing.

The provision of a spring seat of the above mentioned character, for use in connection with tarm' machinery, will enable the operator of the machinery to be seated comfortably thereon. all times be positive and efiicient in their operation.
