JAMES JOHN FLETT, OF CORVALLIS, OREGON.
PERFORATING-MAC HINE SPECIFICATION forming part of Letters Patent N0. 620,436, dated February 28, 1899.
' Application filed March 8, 1898.
' To allwhom it may concern.-
Be it known that I, J AMES JOHN FLETT, of Corvallis, in the county of Benton andState of Oregon, have invented a new and Improved Perforating Machine, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved perforating-machine arranged to properly perforate a large number of sheets of paper, leather, wood, iron, or other material in such a manner that the perforations -extend very close to each other and in perfect alinement to permit of readily detaching the sections of each sheet, as in blankbooks, check, order, note, and other books, 850., the machine being simple and durable in construction, not liable to get out of or der, and Very effective in operation.
The invention consists of novel features and parts and combinations of the same, as will be described hereinafter and thenpointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding partsin all the figures.
Figure 1 is a side elevation of the improvement. Fig. 2 is an enlarged transverse section of part of the improvement on the line 2 2 of Fig. 1. vation of the same on the line 3 3 of Fig. 2. Fig. 4 is a sectional plan View of the improvement onthe line 4 4 of Fig. 1, and Fig. 5 is a transverse section of the same on the line 5 5 of Fig. 1. a
The improved perforating-machine is provided with a table A, on which the material to be perforated is placed. The table A carries an overhanging arm B, provided at its front with vertically-disposed guideways B, in which is fitted to slide a slide 0, formed with a removable frontportion O and provided with a series of bearings for verticallydisposed drills D, extending with their lower pointed ends a suitable distance below the bottom of the slide 0, as is plainly indicated in the drawings. The drills D are arranged in perfect alinement with each other and very close to one another, as plainly indicated in Fig. 3, and each drill is provided at or near its upper portion with a crank-arm D, ongaging a bearing in a connecting-rod E, so that Fig. 3 is a sectional front ele-- Serial No. 673,072. (No model.)
gaged by crank-arms F, arranged on the lower ends of shafts F, moving up and down with the slide 0 and having their upper ends mounted to turn with and slide in bevel-pinions G, mounted to rotate in suitable bearings on the overhanging arm B. The pinions G arein mesh with bevel gear-Wheels G, secured on a longitudinally-extending shaft G mounted to rotate in suitable bearings on the arm B and provided at one end with a crankarm G or other means for imparting a rotary motion to the said shaft. Now when the shaft is rotated the gear-wheels G rotate the pinions G and the said pinions r0-' tate the shafts F, so that the crank-arms F impart a swinging motion to the connecting rod E to simultaneously rotate the drills D.
The slide 0 is provided with an upwardly extending link 0, pivotally connected with a lever 0 fulcrumed on the arm B and under the control of the operator, so that the lever 0 when swung causes the link (J to move the slide 0 and with it the drills D and shafts F to move in a like direction to feed the drills through the material while the drills are rotated. A presser-foot H is fitted to slide in suitable bearings arranged on the cover 0 for the slide 0, and the said presser-foot H has its lower end formed with bearings H for guiding the lower ends of the drills D. The presser-foot H is adapted to rest on the top of the material during the drilling operation, and when the drills are-withdrawn after the perforation is completed by the operator moving the lever O upward then the presserfoot will remain in contact with the uppermost sheet of the perforated material to per-- mit a ready withdrawal of the drills without causing the material to move up through the drills. The presser-footH is pressed on bya spring H coiled on a rod H carried by the cover 0, and the upper end of the said spring rests on a nut H carried by the rod,-while the lower end of the spring abuts against a projection H on the .presser-foot H. (See Fig. 5.) Thus the presser-foot is yieldingly mounted on the slide O.
In order to securely hold the material in operation, I provide a clamping-bar I, exten ding in the rear of the drills to engage the top of the material and press the same firmly in place against the table. For this purpose the clamping-bar I is mounted to slide vertically in bearings B formed on the rear portion of the arm B, and the upper end of said bar is provided with a nut I, in which screws a screw-rod J, mounted to .turn in a suitable bearing B formed on the arm B, (see Fig. 5,) and on the upper end of the said screw-rod is a handle J for turning the screw-rod and moving the bar I downward in firm contact with the material, so as to clamp the same in place 'on the table.
The operation is as follows: The clampingbar I' and the slide 0 are held in an uppermost position to permit of placing the material in proper position on the table A, the line for the intended perforations being directly under the lower ends of the drills D. The operatornow screws the screw-rod J down and moves the bar I in firm contact with the material to clamp the same in place on the table, and then the operator turns the crankarm G and simultaneously presses down on the lever G to cause a revolving of the drills D and a downward feeding of the same to move the drills in contact with the material and bore holes therein, and thus form the perforations. IVhen the material has been bored through, the operator ceases turning the crank-arm G, then moves the lever C upward to withdraw the drills from the material, and then the'clamping-bar I is moved upward to release the material, which can now be removed.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the drills having crank-arms and aXially-alined portions at the opposite ends of each crank-arm, spaced bearin gs in which said axially-alined portions are journaled, and a driving mechanism engagin g the crank-arms between the said bearin gs, substantially as described.
2. A perforating-machine, provided with a slide, a plurality of drills journaled in the slide and movable therewith, and means, likewise carried by the slide to move therewith for rotating the drills, substantially as described.
3. Aperforating-machine,comprisingastationary frame, a slide mounted to move thereon, drills journaled in the slide to move therewith, and driving mechanism comprising a portion carried by the slide and operating the drills, and another portion carried by the frame and having a sliding yet operative connection with the first-named portion of the driving mechanism, substantially as described.
4. A perforatin g-machine,comprisin g a stationary frame, a slide mounted to move thereon, drills journaled in the slide, means for operating the drills, and a presser-foot slidable on said slide, substantially as described.
5. A perforating-machine, provided with a movable slide, a plurality of drills journaled in the slide and having crank-arms, a con- 5 necting-rod for the said crank-arms, and means carried by the slide and movable therewith for imparting motion to the crank-arms, to rotate the drills in unison, substantially as shown and described.
6. A perforating-machine, provided with a movable slide, a plurality of drills journaled in the slide, and having crank-arms, a connecting-rod for the said crank-arms, means carried by the slide and movable therewith for imparting motion to the crank-arms, to rotate the drills in unison, and a springpressed presser-foot fitted to slide on said slide and having bearings for the lower ends of the drills, substantially as shown and described.
7. A perforating-machine, comprising a table having an overhanging arm, a clampingbar fitted to slide on said arm, and adapted to clamp the material to be perforated in place on the said table, a slide vertically adjustable on said arm, a plurality of drills journaled on said slide and having crank-arms, a connecting-rod for the said crank-arms, and means for imparting motion to the said connectingrod, to rotate the drills in unison, substantially as shown and described.
