'CONDUCTORS PUNCH.

SPECIFICATION forming part of Letters Patent No. 736,116, dated August 11, 1903. Application filed February 11, 1903. Serial No. 142,840. (No model.)

T on whom it may concern! Be it known that I, RICHARD J. KRAUT- HEIM, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented and produced a new and original Improvement in Conductors Punches; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had tothe accompanying drawings, and to letters r the durability of a punch and to render the of reference marked thereon, which-form a part of this specification.

The objects of the invention are to increase same more positiveinits action, to facilitate the construction and to reduce the cost there of, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of.

the working parts. I

The invention consists in the improved conductors punch and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim. Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a plan of the improved punch. Fig. 2 is a section of the same, taken at line 00 of Fig. 1. Fig. 3 is a side elevation of a forward part of said punch; and Fig. 4 is a sectional detail taken at line y, Fig. 3. Fig. 5 is a plan and section of a female die-section.

In said drawings, a and b indicate, respec-' tively, the male and female members of the punch, of which the female member 1) consists of a casting which is horizontally cut by a saw or otherwise split, as at c, to provide a narrow receptacle for the ticket or card to be vertically perforated, as at g, and is countersunk on the upper side, and thus provides a punchedwith relation to the dies.

' seat h for the female die 2', the seat being formed, as shown in Fig. 4, by boring into the upper side of the prong to form a round aperture, into which is fitted the said die member. The said female die 1' is disk-shaped and recessed at one side, as atj, and is fastened into the boring or aperture by forcing the metal 70, forming the side walls of the aperture, into the recess j, as indicated in Fig. 4. The inner wall of the recess is inclined, as shown in Fig. 5. By this construction the said female die is seated with great exactness and security and at a comparatively small expense of time and labor.

The prong d is slotted vertically to receive the section or member a, the slot Z being enlarged near the forward extremity of the prong, as at m, to provide a round sightopening, by means of which the conductor-can see the position of the card or ticket to be Heretoforethis sight-opening m has been extended at the sides of the male member a to a point distant a half-inch from the male die n. In the present case the side walls 0 o of the slot Z extend parallel and in contact with the member a up to a point vertically in line with the inner part of the male die n, of the punch, and thus there is no chance of the handled member a at its forward extremity springing laterally when punching, and thus preventing a proper entrance of the male die into the female die to efiect an exact and perfect punching operation, and, furthermore, because of the long bearings for the forward extremity of the member a there is less op- 'portunity to wear the said side walls of the member 12 away, and thus permit a lateral looseness of the members inimical to a proper punching operation.

The members a and b are pivoted or ful-.

male member, the walls of the slot extending at the sides of, and in contact with the male member to the line of the die thereof, and, at

, said line, the said slot being laterally enlarged to form a sight-opening around the extremity of the male member to permit the entrance of light to the ticket as the same is about to be punched, substantially as set forth.

2. The improved punch herein described, comprising the pivoted and handled members, each provided with a punching-die, the male member having a slot with a round enlargement at its forward end, the said enlargement forming a sight-opening, and the parallel-sided side walls of the slot extending along the sides of and in contact with the male member up to the sight-opening immediately
