To aZZ 20710112, it army concern:
Be it known that I, JOHN H. VINTON, of Bos ton, county of Suffolk, and State of Massachusetts, have invented an Improvement in Ma- 1 5 chines for Slotti'ng' Tubes, of which the follow panying drawings, is aspecification, like letters cutter through the tube.
d the buttons following in the slot.
- ing description, in connection with the accomon the drawings representing like parts.
-;This invention has for its object the production of an apparatus for slotting longitudinal] y metallic tubes. Q
The invention consists of a suitable clamp to hold the tube to be slotted, said clamp being constructed with a slot at one side substantially of the width desired for the slot in the tube, combined with a cutteradapted to be drawn through the tube coincident with the slot in the clamp,'and means for drawing the The clamp is herci'nshown as composed of a block having a longitudinal recess of sufficient depth to receive a wedge-shaped bar and also the tube tobe slotted resting upon it. Two parallel gage-bars are secured to the block,
' partially covering the recess, the width between the bars being substantially the width desired for the slot in the tube.
The cutting-tool for cutting the slot consists of a cuttingblade secured to or made integral with a bar, which bar is placed within the tube. The tube containing the cutter-carrying-bar and resting in the recess of the block upon the wedge-shaped bar is lifted by said wedge-shaped barfirmly up against the par-' allel gage-bars secured to the block, so that the cutting-blade enters the space between said gage-bars.
An engaging device adapted to engage the cutter-carrying bar is provided, which is attached to a movable blocker carrier, movementof said block or carrier acting to draw the cutter-carrying bar and 'its attached cuttin g-blade through the tube, said cu tting-blade ;d, as shown in Fig. l, is placed in the recess Q 7 suitable engaging device, herein shown as an arm, e,.pivoted at 3 to a standard, e,.saidarm cooperating with thetwo parallel gage-bars tocuttheslot. The slot is cut from the inside outward, so that should there be a projecting fin or up Wardly-turned edge such edge will be formed 5 5 upon the outside of the tube. .Figurelshows in side elevation a tube-slotting apparatus embodying t'hisinvention; Fig.- 2, a cross-section of the same, takenon the dottedline a: at}, Fig. 3, a perspective View of the cutter; Fig.4., a cross-section of the tube previousto being slotted, and Fig. 5 a similar cross-section of a tube after it has been slotted. Theinain frame a, has secured to ita block, r a, recessed at its upper side to receive, a 6 wedge-shaped bar, I), and above it the tube 0 to be 'slitted. The wedge shaped, bar b is loosely connected with an operating-lever, 'bf, pivoted to the frame aorfba'se of the apparatus,moven1ents of the said lever b effecting a substantially horizontal movement of the Wedge-shaped bar in the recess'of the block} Two'parallel gage-bars, cc, are secured by screws2 to the upper side of the block'a, partially covering the recess formed therein, asbest shown in Fig. 2, the distance between the 7 two gage-bars being of substantially the'width desired for the slot to be cut in the tube 0. j The tube a is. herein shown as rectangular in'cross-.;
section, although it is obvious thatja tube of any desired shape in cross-section may be operated upon. The tube'c of sheet metalreceives a cutter-carrying, bar, d, to which-is secured a cutting tool or blade, d,- orsaid cute ting tool'or blade may be formed integral'with 8 5 the bar, the cutting-blade andbar together forming the cutter. V
The tube inclosing the cutter-carrying bar in the block a upon" the wedge-shaped bar '12, 9o
"and the said bar is thereafter moved inv the direction of the arrow, Fig. 1, thereby firmly" holding'the tube against theunder'side oft-he gage-bars 0 c f v The cutter-carryingbar d is engaged by a having'upon its .under side a projectingpin or stud,4, (see dotted lines,) which enters ahole cut inthe bar d near its end. .A cam-bloch', too.
e pivoted to the arm 6, bears upon the upper side of a rack-bar, f, arranged to slide in an extended portion of the frame a. The standard of the arm e is attached to the rack-bar f, so that as said rack-bar is moved the engaging device for the cutter will be moved with it.
A toothed wheel, f, is mounted upon a shaft having its bearings in a standard, f, attached to the main frame, said shaft revolved by a crank, f so that after the tube has been wedged into the position shown in Fig. 1, and
above described, by turning the crank f the cutter will be drawn through'the tube, removing the material thereof between the two par allel gage-bars c 0 leaving the tube as shown in Fig. 5.
It is obvious that tubes of any desired shape in cross-section may be operated upon in this manner, that the slots cut may be of any desired width, and that the projecting fins or edges left by cutting itwill be turned outward.
I claim- 1. In an apparatus for slotting tubes,a clamp to hold the tube and a cutter adapted to be drawn through the tube, combined with means tially covering the recess of the block, and
means for holding the tube to be slottedfirmly sisting of a recessed block, two parallel gagebars partially covering the recess in the block, and a wedge-shaped bar to firmly raise the tube against the parallel bars, combined with a cutter adapted to out the tube coincident with the space between the parallel gage-bars,
substantially as described.
5. In an apparatus for slotting tubes, the clamp to hold the tube and a cutter adapted to operate within the clamp to cut the slot in the tube, combined with an engaging device for the cutter, and means, substantially as described, for moving the engaging device, as and for the purposes set forth. v
6. In an apparatus for slotting tubes, a clamp composed of a recessed block to receive the tube to be slotted, two parallel gage-bars partially covering the recess of the block and formed at their lower edges to present cuttingedges, and means for holding the tube to be slotted firmly against the two parallel gagebars, combined with a cutter adapted to bedrawn through the tube coincident with the opening between said parallel bars, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN H. VINTON.
