UNITED STATES PATENT @refont ROBERT H. IRELAND, AOF NEW. YGRK, N. Y.
BEAM-FLANGE PUNCH.
SPECIFICATION forming part of Letters Patent N o. 531,946, dated January 1, 1895.
Application tiled October 11, 1894. Serial No. 5259586. (No model.)
To all whom t 11i/wy concern,.-
Be it known that I, ROBERT H. IRELAND, of New Yori; city, in the county and State of New York, have invented anew and Improved Beam-Flange Punch, of which the following is a full, clear, and exact description.
My invention relates to an improvement in punches adapted especially for use upon the flanges of beams, and the object of the inven` tion is to provide such a punch which will be simple and durable as well as economic, and in which both the punch and die block may be simultaneously adjusted in a convenient and expeditious manner.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed ont in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.
Figure l is a vertical section through the improved punch, taken practically on the lines l-1 of Figs. 2 and 4. Fig. 2 is a horizontal section taken practically on the line 2-2 of Fig. 1. Fig. 3 is an end view, a portion of the machine being broken away; and Fig. 4 is a vertical section taken substantially on the line 4--t of Fig. 1, the said section being at right-angles to the section shown in Fig. 1.
In carrying out the invention the framework of the machine may be said to consist of two tables A, one placed opposite the other, the two being at predetermined distances apart, or a sufficient distance to readily receive between them a flange as well as the web, for example, of an I beam. The tables A are preferably made tapered, in order that they may be as light as possible consistent with strength. Each table, near its outer end, supports ablock B,said blocks being also tapered, and the blocks in their turn support two side beams C, of preferably 2li-formation,
the beams being tied together at their ends by end plates D, and at each side of the oenter by intermediate plates D', as shown inE Fig. 1, the connection between the plates and beams being effected by bolts vor other approved means.
The side beams C serve to support pillow blocks E. In these pillow blocks the drive shaft 10 of the machine is mounted to revolve, being provided preferably with a balance wheel 11 at each end, and fast and loose pulleys 12 and 13 near the center. The shaft l0 is likewise provided with a pinion 14., which meshes with a gear 15 secured upon a driven shaft 16, the said shafts being journaled in blocks 17, secured to about the central portions of the side beams C, the said blocks being provided with bosses which extend outward through the openings in the said beams, as shown in Fig. 1.
About centrally between the side beams C the shaft 16 is provided with two eccentrics 1S and 19, oppositely disposed; and between the guide plates D in the upper portion of the frame, two movable frames 20 and 2l have Vertical and sliding movement. These frames are placed face to face, and while the plates D serve as guides for the outer edges of the frames the outer side faces of the said frames are guided by the blocks 17 that are bearings for the eccentric shaft 16. The shaft 16 is made to pass through two large rectangular openings 22, one of which is made in each of the said sliding frames, as shown in Fig. 1, and it may here be remarked that the frames themselves are preferably of a rectangular shape.
In the opening 22 of each sliding frame a second frame 23 is held to slide. The said frame 23 extends from side to side of the opening in which it is fitted, but is of less length or height than the opening, whereby in the absence of a tumbler the inner frames 23 may move in the outer or main frames 2O and 2l without affecting the latter.
Within each of the second or inner frames 23 an eccentric strap 24 is held to slide in a lateral direction, each strap receiving one of the eccentrics 18 or 19. In the lower portion of the opening 22 of each main sliding frame a tumbler is placed, said tumblers being designated respectively as 20"u and 21'. These tumblers are pivoted at their lower ends in the bottom portion of the openings 22, and when carried to an upright position engage with the bottom portion of the inner sliding frame 23 of the main frame in which they are located, serving to hold the two frames in ICO such connection that they will be moved in unison up and down by the action of the eccentric straps 24 having lateral movement in the inner of the two frames.
Each tumbler is provided with a crank arm 25 formed upon one of its trunnions and operated by a handle bar 26 or the equivalent thereof extending outward for example at one side of the machine, as shown in Fig. 3.
Upon the bottom of each of the main or sliding frames 2O and 21 aplate 27 is secured, as shown in Fig. 4, being provided preferably with a longitudinally located dovetail groove 28 in its bottom face; and a chuck head 29 is located in each groove 28, the body 30 of the chuck proper being of any approved formation capable of receiving a punch 3l, or like tool.
A die block 32 is mounted upon the upper face of each table A at its inner edge, and the two die blocks are ordinarily and preferably located diagonally opposite each other, as shown in Fig. 2, each block being provided with one or more slots 33, through which adjusting screws 34 are passed; and each die block is provided with a die 35, conveniently located thereon, ordinarily at or near the inner edge, as shown in the said Fig. 2.
Each die block at its outer end is provided with an integral or attached upright 36, and each upright is forked at its upper end,being provided with a slot 37 receiving a pin 38, the pins having sliding movement in the slots, yet cannot be laterally removed therefrom unless it is so desired. This is accomplished by forming an enlargement or shoulder 385L on each pin 38 and screw threading the end of the pin as seen at 38b to receive a nut 38. When the parts are assembled, the shoulder 38a bears'on the inner face of the slotted upright 36, and the nut 38c forms a shoulder which bears on the outer or opposite face of said upright as clearly seen in Fig. l.
One of the pins 38 is secured to each of the chuck heads, whereby the chuck having been centered so that the punch will be over the die of the block in connection with which it is to operate, when the block is adj usted inward or outward to increase or decrease the distance between it and the opposing block, the punch will be moved together with the block, and consequently the centering of the punch will never be interfered with.
The adjustment of the die blocks isaccomplished preferably through the .medium of screw shafts 39, that have a'swivelconnection with the uprights 36 of the die blocks, and a threaded engagement with nut blocks on the blocks B. They are journaled in the spacing blocks of the machine frame and each operated by a hand wheel 40 or its equivalent, located on the end of the shaft outside of the frame.
In the operation of this machine the punches work alternately, and either one ot` them may be placed out of action by tripping the turnblers of its carrying frame, and the die blocks may be adj usted to or from one another to accommodate the thickness of the web of the beam to be punched and the width of the flange, together with the location at which the punching is to be effected.
Having thus described my invention, I- claim as new and desire to secure by Letters Patent` Ina machine for punching metal beams and the like, the combination of two tables spaced apart to receive the web of the beam, dieplates movably mounted on the respective tables, a shaft connected to each die-plate and provided with a screw thread engaging a threaded portion on one of the tables, and having a hand-wheel or the like at its end, whereby the die-plates .may be adjusted to different distances apart to accommodate different thicknesses of the web ofthe beams to be punched, an upright forked at its upper end and secured to the ou ter side of each die-plate and punching mechanisms arranged over said tables, each of said mechanisms including a die-carrier having apin provided with ashoulder adapted to bear on the inner face of the slotted upright of the die-plate on its respective table, and having beyond said shoulder a screw threaded portion adapted to project through and move longitudinally in the forks of the upright, anda nut adapted to be screwed on said screw-threaded portion of the pin and forming a shoulder adapted to bear on the opposite outer face of the upright, substantially as set forth. v
ROBERT H. IRELAND.
