BOLT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,102, dated December 28, 1886.

Application filed December 15, 1885. Serial No. 185,711. (No model.)

To all whom it may concern:

Be it known that I, ALBERT W. RosE, a citizen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Heading and Cutting Bolts, of which the following is a specification, to wit:

This invention relates to an improvement in bolt cutting and heading machines; and it consists in certain peculiarities of the construction of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and use, referring to the accompanying drawings, in which-- Figure l is a plan view of a boltheading machine fitted with my improvement, and Figs. 2 and 3 are detail views of the improvement.

A represents the main frame of a machine for heading bolts. This machine is of awellknown form, having a stationary die, a, and a movable die, a, which is carried upon'a rock-shaft, A, journaled in the main frame.

' This movable die is provided with an arm, B,

connected to a lever, B, fulcrumed on one end of the machine, and given an oscillating motion by a cam or eccentric, B on the main driving-shaft B This portion of the machine is well known, and does not need further description or illustration in this connection. It has been -usual in these machines to place upon the oppositeend of the machine a second lever, the heel of which has a blade or similar device for cutting the bolt off the blank or rod at a given length; but this involves a greater expense in manufacture, and it is difficult for the operator to hold the rod firmly during the operation. To obviate this I provide the stationary die-plate a, below the headingdie, with a cutting-blade, O, having its end notched at c to conform to and receive the blank. The movable die is pro- .vided with a similar blade, 0, also notched at c.

beneath the blades, and is slotted, as at d, that it may be set in or out to regulate the length of the bolt cut off. The notches in the ends of the blades, as will be seen in Fig. 3, are slightly beveled, and this serves to partly point the bolt as it is severed from the rod. The operation is quickly performed, while the blank'is held in the notched ends of the blades, and has notendency to twist in the hands of the operator.

It will be understood that the cutting-dies are immediately below and in line with the heading-dies, and after the bolt is headed and the moving die swings back to release it, it is at once simply drawn out and dropped down upon the gage D, where it is in proper position to be cut by the cutting-dies as they swing together again. is such that the headed bolt does not require any guiding to position, but is naturally dropped into the exact position required to meet the cutters.

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

Y .The stationary die-plate a and oscillating plate a, in combination with the cutting blades 0 O,having beveled notches c c in their ALBERT w. ROSE.
