These and other objects of invention will in part be set forth hereinafter and in part will be obvious herefrom.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown andv described.

The accompanying drawings, referred to herein and forming a part hereof, illus` trate one embodiment ofthe invention and together with the description serve to eX- lain the principlesthereof.

Fig. 18 is a fragmentary section on line P-f-Q, of Fig. 13. Y

Fig. 19 is a diagram of the distancerecord sheet and controlled circuits.

Referring to the embodiment illlustrated by way of example in the accompanying drawing, suitable means are shown for traveling and stopping a structural shape, such as an I- beam ai, relatively to the punching devices to be punched thereby. The particular form of such means is immaterial so far as concerns many features of our invention, and as embodied we have illustrated in a general way the form of such means shown in co-pending application for Patent Serial No. 814,380, filed January 26, 1914,

for traveling the beam longitudinally. In the illustrated form the shape rests upon i a series of driveny rolls 1, arranged in a horizontal pathway past one or more punching mechanisms.

The travel and stopping of the beam w relatively to. the punching means is controlled by distance determining devices, and connections therefrom tothe beam, As embodied, a head 2 is in delinite position with respect to the shape a", traveling therewith in such definite position, and preferably the leading end of the shape abuts against the head 2. Fixed tothe head 2 isa long rail or bar 3 extending backwardly along the shape m and traveling preferably guiding rollers 4. The bar 3 is provided on its top face with gear teeth 5, with,` which meshes the pinion .on the shaft of the distance determining device as shown in application SerialfNo. 814,380 before referred to. Thus the shape is traveled and stopped in accurate conformity with the setting ofthe distance determining devices to have the holes punched therein 'at the points or positionsin the beam corresponding to the settings ofthe distance determining devices. i

Referring now more particularly to the embodied punching devices, hydraulic means are provided for bringing the punch and die to the work and for punching the holes in the beam. Said punching mechanism is mounted in a vsuitable housing or frame, comprising plates 10'and 11, arranged vertically and parallel to each other and supported further by suitable means such as base angles 12, and having connecting .ties orstays 13. Means for effecting relative movement between the punching mechanism and the beam in a Adirection transversely to the length bf the beam and-in accordance with the settings of the distance determining devices are provided, and in the embodied form the punching mechanism travels trans, versely relatively to the beam under the control of the distance determining means.

In such embodied form upon the

plates

10 and 11 horizontally arranged guides 15 and 16. Reciprocably mounted in said guides 15 and 'of cross frames or cross heads arranged at either side of the punching mechanism y proper, the upper cross head 17 and the corresponding lower cross head 18 being shown in section in Fig. 1, and being shown in their entirety in Figs. 13 and 14. The corresponding pair of cross frames 19 and 20 are arranged upon the opposite side ofthe punching mechanism and likewise reciprocate in the respective

horizontal guides

15 and 16 carried by the

plates

10 and 11. The cross heads or cross

frames

17, 18, 19 and 20 are each apertured medially of their length.- In the apertures of cross frames 17 and 18 is in suitable, guides,

there are carried' -41 is supported by vcollars or lugs 53 and 54 fast to the cylinder 16 are pairs and 22 end of the frame piece 23, lthe frame piece 'being secured in position upon the rods between collars 24 and nuts 25. Supported upon the frame piece 23 is a die-block 26,

4which coperates with the punch as hereafter described. At the upper end of the' vertically reciprocable rods 21 and 22 is carried the frame piece 30, said frame pi'ece 30 being secured to the rods betweencollars 31 and nuts 32.

Means are provided by the invention for ioating the punch and die, that is, automatically centering them with respect to the work irrespective of the size of beam being run through, as in the case of punching the web of an I-beam. If different sized beams are'run in on the rollers 1, the height or position of the web will vary dependent upon the depth of the flange of the beam, andit is desirable and also necessary for rapid work that the punching mechanism automatically center itself with respect to beams of di'erent sizes. In the embodied form, whicltis adapted to av hydraulic punch, a plunger 40 is fixed to the frame. piece 30, the plunger 40 being hollow. Surroundin the plunger 40 is a cylinder 41, provided with a suitable packing ring or like device 42. The' `cylinder 41 is provided from a distance record sheet such as is shown and described -in application Serial No.

814,380, tiled January 26, 1914. The

cylinder rods

51 and 52 secured to 41, and also fastened to a cross frame 55. A plunger 57 is fixed to the cross frame 55 the cylinder head and the in a suitable manner, as by a screw thread 56 in an aperture in the frame 55. The plunger 57 works in a cylinder 58 in the frame piece 30, the cylinder 58 communicating by a passage 59 with a suitable source of fluid pressure supply, such as a pipe 60.

The manner of operation of the punching mechanism described and shown is substantially as follows:

When the mechanism is at rest, the threeway valve 48 cuts off the pressure from the interior of the hollow plunger 40 but the pipe 60 is under pressure. Thus the cylinder Lainate 41 is lifted to its upper position as shown in 66 and 67 reciprocably carried by the cylinder Figs. 1, 2 and 3. When the punch is to be 41, the

springs

68 and 69 being in compresactuated, the three-way valve 48 is operated, sion between the cylinder and the bar 65. either by the solenoid 50 or otherwise, to In Fig. 5 of the drawings, a battery of 5 admit the pressure fluid into the hollow punches. is shown, comprising a flange 70 plunger 40, the admitted fluid passing punch, such for instance as is shown in cothrough the port 45 into the space 46 bepending application, Serial No. 834,908, filed tween the plunger 40 and cylinder 41.

prises a cylinder 82, having a plunger 83 operated by the fluid pressure in said cylinder and moved thereby forward from a solid line position as shown in Fig. 5 to a dotted line position as shown in said figure. The travel or movement of the plunger 83 will vary according to the size of the shape, and the pressure may be of any desired amount irrespective of the distance of travel of the plunger 83. Suitable connections for the cylinder 82 to convey and control the fluid under pressure are provided and Will On the opposite side of the punching mechanism c similar pinching and alining rollers are shown, and need not be described in detail, and have the same reference numerals applied thereto.

4In Figs. 7, 8 and 9, a system of fluid `pressure actuating means and controls for the general arrangement or system of punches just described are illustrated, the parts being somewhat differently disposed and proportioned for the sake of clearness. As embodied, the system will be regarded as hydraulically operated and in certain aspects of the invention this is the preferred form. The pressure tank 90 is kept under VYsubstantially constant pressure in a suitable manner,- as by an air pump 91 driven by a suitable motor 92, although so far as concerns many featuresl of the invention the pressure could be maintained and regulated in the tank 90 otherwise, as by a system of weights for example. Suitable means for controlling the pump 91 and motor 92 to maintain a constant pressure in the cylinder 90 may be provided of any desired or approved form.

The water is kept in circulation and at pressure in the system by a pump 93 driven by a motor 94, suitable controls of any approved kind being provided therefor. Pressure pipe 95 connects to pressure pipe 96, which communicates by a pipe 97 with the accumulator tank 90. A general return or exhaust pipe 98 communicates by a pipe 99 with a return or reservoir tank 100. A

pipe 101 connects from the bottom of tank 100 to the pump 93. The cylinder 76 at the right (Figs. 5, 6 and 7 is provided with a three-way valve 102 controlled by a suitable pilot valve 103, which may be automatically operated by a solenoid 104, which solenoid may be controlled by a distance record strip. The pressure pipe to the valve 102 is indicated by reference numeral 105. The cylinder 82 is provided with ports 106 and 107,

which are controlled by a valve 108, suppliedl by a pressure pipe 109 and operated by a pilot valve 110 having an automatic solenoid control 111, said solenoid being controlled from the distance record strip. The return or exhaust pipe for the foregoing is indivalve 118, operated by a pilot valve 119.

automatically controlled through a solenoid 120. The valve 118 is supplied with the Huid under pressure by means of a swivel jointed pipe 121 having joints permitting of vertical .and horizontal cylinder 41h. A similarly swiveled exhaust pipe 122 connects from the valve 118 to the pipe 98. Cylinder 41c is provided with a main valve 123 and a pilot valve 124, which may likewise be automaticallyI controlled as already described. A swivel pipe 125 connects from the valve 123 to a pressure pipe 96, and a swivel pipe 126 connects from valve 123 to the exhaust or return pipe 98. The left hand cylinder 76 is provided with a main valve 127, and with a pilot valve 128 which may have an automatic solenoid control. The pipe 130 supplies the pressure fluid to valve 127 through pipe 131, and pipe 132 communicates from valve 127 to exhaust or return pipe 112. Left hand cylinder 82 is provided with a main valve 133 and with a pilot valve 134, which may have the automatic solenoid control. Valve 133 is supplied with pressure fluid through pipe 135 and-communicates by pipe 136 with return pipe 112.

The invention, in accordance with certain features thereof, provides a form of the device whereby the entire centering is not eected by the cylinder, but the punch blocks and die blocks are preliminarily positioned or' centered for beams or shapes of different sizes, and the working stroke there- `by shortened and the time of operation decreased. In this case the floating action of the cylinder and plunger is employed only to bring the centered punch and die to the work and to make the perforations. In the embodied form (Figs. 12, 13 and 18), the rods 21 and 22, are screw threaded at their upper end, as indicated by reference nu-, meral 140. Screw thread 140 on said rods 21 and 22, respectively, engages the internal thread of a sleeve 141, which sleeve is rotatably supported in cross frames 17 and 19, and having a collar or flange 142 seated upon the bracket. Fixed to each sleeve 141 is a worm wheel 143, which meshes with a worm 144 on a shaft 145, which shaft extends across the machine from rod 21 to pipe communicating with,

movement of the f rody 22. Shaft 145 is driven by a gear 146 aperture in the' movable punch bevel gear 162.

and a pinion 147 from motor 148. Motor 148 may De controlled bv the distance record sheet such as is shown in application Serial No. 814,380 already referred'to. Thus as the shaft 145 is rotated, rods 21 and 22 are raised or lowered, and the center of the unches and dies moves therewith, to suit the size of the beam which is fed in on the rolls 1.

Means are provided by the invention, in accordance with one of its features, for positioning the punches and dies with respect to each other, and also for effecting and controlling such relative positioning lfrom the distance recordl sheet. As em'- bodied, one punch and-die, or one set of the punches and dies are fixed in position, as shown in Figs. 1 2' and 15, Rotatably mounted in the stationary punch'block 150 vis a shaft 151. Shaft 1,51Y -passes block 153 and is screw threaded at 152 to engage an internal'thread formedin the aperture in punch block 153. Shaft A151 connects by a universal joint 154with`a short shaft 155, said shaft 155 being journaled in a bracket 156 supported on cross frame 20.

A similar arrangement is provided for the die blocks, a shaft 157 being rotatably mounted in a fixed die block 158. Shaft 157 passes through a movable die block 159, the shaft having a screw thread 160 engagin an internal thread in the aperture of the die block 159. Means are provided for rotating

shafts

155 and 157 to and' fro to correspondingly move the punch and die

blocks

153 and 159, and as embodied shaft 157 has a beveled pinion 1.61, meshing with a Gear 162 is fixed on a sleeve 163 embracing rod 22. Fixed also to sleeve 163 is a bevel gear 164 meshing with a bevel pinion 165 fixed on shaft 155. Thus

shafts

155 and 157 rotate in unison, while provision has been made by joint 154 for the reciprocation of the punches. Joint 154 also has a telescoping action due to changes in the level of

shafts

151 and 155. Sleeve 163 is rotated to and fro by suitable means, such as a bevel pinion 169 meshing with gear 164 and fixed to a shaft 170. to which shaft is also fixed a slip or friction gear 166, driven by a pinion 167 driven by a motor 168.

The movement and positioning of the punches and dies are controlled by suitable devices. and in accordance with one feature of the invention. this is effected from the distance record `heet or by manually settable devices. As embodied, solenoid operated means are provided for this purpose. (')n bracket 156 are supported a series of solenoids 171.l which have suitable circuit connections to the distance record sheet or to the manually settable devices. The solenoid cores operate pins 17 2 working in aperthrough an V .dicated by b tures in the walls of the-supporting ring or bracket 156. Extending downwardly (Figs. 16 and 17 from the bevel gear is a lug 1 3 which is engaged by any set pin 1-72, thus stopping the gear 164, the sleeve 163 -and gear 162, and thus positioning-the punches and dies at the desired point. If desired, a like stop pin control could be applied to shaft 145.

D is the solenoid actuated switch controlled from stop circuit of the longitudinal distance determining device, and controlling the movement and stopping of rack bar 3 in the manner described and referred to, land also controlling the motor driving the rolls 1. Switches B, C and D time the action of the punch by holding the circuit open until the various motors all come to a stop.

C is a similar switch, y

The windings of the gag solenoids, shown in Fig. 15 of the drawings. are indicated in Fig. 19 by the word Gags, the distance record sheet thereby selecting the desired punches. Other solenoids may be controlled from the distance record sheet in like manner. and the circuits therefor would be shown practically as duplgites of some of the present circuits. WW

The mechanism just described for automatically regulating the relative positioning of the punches and dies has been made the subject-matter of a divisional application, Serial No. 179.887filed July 11. 1917.

From all the foregoing it will be understood that mechanism has been provided realizing and embodying the objects and advantages herein set forth, together with other objects and advantages. It will be further understood that changes may be made from the precise form of mechanism shown. within the scope of the accompanying claims. without departing from the prin- `ciples of the invention, and without sacrishape, and
