To all whom it nut 1 /066776: shaft as may be preferred, from which a belt Be it known that I, GEORGE Q. ADAMS, a F extends to a pulley G, located on a countercitiZen of the United States, and a resident shaft II. There also extends upwardly a belt of Quincy, in thecounty of Adams and State I, which passes over a flanged pulley .I on a of Illinois, have invented a certain new and counter-shaft- K at the upper part of the ma- 5; useful Roller Feed for Power Fence -Ma chine. On this shaft are located thefollowing chines, of which the following is a speciticawheels: first, a grooved pulley Ii; next, the

Thus the rotation of the feedrollers M and N is intermittent, depending upon whether the roller L on the shaft K is upon the larger diameter of the wheel R or not. It willthus be seen that the feed-rollers operate to feed the pickets into the machine at the proper time only, and that there is no possibility of the pickets being taken into the machine at an improper time. Thus accident or fracture to the machine from this cause is obviated.

, It will be at once perceived by those who are familiar with this art that various modifications of the details of construction mav be made and stillthe essential features of my invention be present.

l. The combination, in a fence-making machine, of an upper and lower feed-roller constructed and arranged to have intermittent separation from each other and driving mechanism forthe rollers, constructed and arranged so that when the rollers are separated they will be at rest, substantially as set'forth.

2. The combination, in a fence-making machine, of two sets of feed-rollers, one set constructed and arranged to have intermittent separation from the other, and driving mechanism for both sets of rollers, constructed and arranged so that they shall be at rest when the first set of rollers is separated from the other, substantially as set forth.

3. In a fence-making machine, a Wheel having two diameters, a shaft supporting a feedroller, the end of the shaft to which the feedroller is attached being capable of limited downward movement, a roller upon the shaft, which engages with the larger diameter of the wheel having two diameters, a flanged pulley on the shaft, and a belt going over some moving part'of the machinery placed below the said shaft, substantially as set forth.
