To all whom it mag concern:

Be it known that I, ANG s MCKENZIE, a subject of the King ofGreat Britain, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Column-Forming Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, and to the numerals and figures of reference marked thereon, in which Figure 1 is a perspective view of the machine, showing all of the different parts properly assembled; and a perspective view of a finished column.

The present invention has relation to machines especially designed for the forming of columns or fluting sheet metal tubes either tapered or straight and it consists in the novel construction and arrangement of the differ-.

ent parts hereinafter described and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanyin drawin s, 1 and2 represent the end stancfards, which are held in vertical osition in any well known manner and their top or upper ends tied together by means of the tie-bar 3. Inthe end standard 2 is journaled the power: shaft 4, which power shaft has loosely mounted thereonthe power wheels 5, which power wheelsin this instancebeing driven'by the cross and open belts 6 and 7, and between the power wheels 5 is located the clutch 8 which clutch may be of any desired construction, in as much as the clutch within itselfforms no particular part of thepresent invention so far as its detail of construction is concerned, as its only purpose is to shift the power from one of the wheels 5 to the other. Upon the power shaft 4 is securely mounted the pinion 9, which pinion meshes with the gear wheel 10, which gear wheel is securely mountedupon the shaft 11,

and upon the shaft ll is securely mounted the sprocket wheel 12, fromwhich sprocket Wheel leads the chain 13, which chain extends around the sprocket wheel 14, said s rocket 'wheel being mounted upon the sliaft 15 and theshaft carried by the standard 1.

To the standard 2 is securely attached the bar 16 by means of the flange 17. The' top or upper face of the bar 16 is provided with a groove 18, in which grooves seated thediebar 19, the top of which die-bar is formed of a shape to correspond with the shape designed to be given to the metal coinposlng the column or pi e. g

It will e understood different configurations or different shaped flutes or corrugations may be desired, and hence anumber of die-bars may be employed, each having a different shaped workingface and the die-bars changed from time to time, owing to the design designed to be given to any particular class of columns or pi es. p g g For the purpose 0 supporting the opposite end of the bar 16 during the time a col umn or pipe is being operated upon the pivoted su port 20 is rovided, which support is pivotal y attache to the standard 1 1n any convenient and well known manner.

For the purpose of operating the support 20 that is to say to bring it out of the way when it is desired to place the pipe in position, and to bringthe support into position to properly support the bar the handle 21 is provided. Upon the bar 3 is slidably mounted the'head 22, which head isconnected at its opposite ends to the drive chain 13, said head a by t e'action of the" drive chain as hereinafter described. To the head 22 is pivotally of forcing the bars 41 away from the seats of attached the bar 23, which bar carries the the grooves formed in the heads 40. For the forming roll 24.

It will be understood that the forming roll '24 should be set so as to properly form the metal as it passes over or upon the pipe and in order to provide for the proper adjustment of pressure the screw threaded shaft 25 is provided, upon which screw threaded shaft is mounted the hand wheel 26, the screw threaded shaft being carried by the head 22, and when said head abuts against the bottom or lower end of the screw threaded shaft 25, it will limit its upward or hinge move ment, thereby holding the forming roll in contact with the metal. After a pipe or column has been properly located upon the diebar 19 as illustrated in Fig. 1 and the support 20 brought into the position illustrated in said Fig. 1, power is applied and by means of the chain 13 the head 22, together with the different parts carried thereby is moved over the pipe and the forming roll brought into action upon the metal or in other words, the metal is crimped or formed by the die-bar 19 and the forming roll 24. Onefull movement of the head 22 will form by-means of the forming roll 22 carried by said'head, one flute or configuration of the column or pipe. Af-

ter the head 22 is brought into such a position that the forming roll 24 is carried beyond the end of the column or pipe, the bar 26 carried by the head 22 will come in contact with one of the reciprocating bars 27, said reciprocating bars being held in the path of the bar 26 by means of the brackets 28, which brackets are secured to the bar 3 or its equivalent. The opposite ends of the reciprocating bars 27 are pivotally connected to the bell cranks 29, which bell cranks are pivotally attached to the brackets 30, which brackets are carried by the end standards 1 and 2. To the bell crank 29 are pivotally attached the links 31 ,which links extend downward and are pivoted to the arms 32 by means of the compound joints 33 and 34.

It will be understood that when the outer portions of the bell crank 29 are moved by the reciprocating bars 27 the arms 32 will be moved upward by means of the links 81, thereby rockingthe shaft 35, which shaft is journaled in the standards 1 and 2. To the rock shaft 35 are attached the arms 36 and 37, to which arms are attached the links 38 and 39 and to the top or upper ends of said links are pivotally attached the grooved heads 40, which grooved heads are each provided with the toothed bars 41, which toothed bars are located in the grooves formed in the heads 40 and are held by means of the pins 42, which pins are seated in the apertures 43 formed in the heads 40, and 51. Between the bars 41 and the seat of the grooves formed in the head and around the pins 42 are located the springs 44, which springs are for the purpose ward and by reason of the ends of the purpose of providing adjustment in addition to that allowed by the springs the pins 42 are provided with the elongated slot 45, through which elongated slots are )assed the connecting pins 46, thereby al owing a limited movement of the pins 42.

It will be understood that the heads 40 should be so spaced from each other that the distance between said heads will be about equal to the length of the column or pipe designed to be acted upon, and for the purpose of varying the distances between the heads 40 from time to time the arm 37 is adjustably attached to the rock shaft 35, by which arrangement said arm can be moved to any desired point upon the shaft 35 and held in fixed adjustment by means of the set screw 47 or its equivalent.

1t will be understood that when one of the reciprocating bars 27 is moved in the direction to elevate the outer end'of one of the bell cranks 29 the heads 40 will be moved up- 1 e being snugly seated against the toothed beiis 41 the column or pipe will be carried with the head thereby setting the pipe for another or the next flute or configuration to be given the pipe or column.

For the purpose of bringing the heads 40 into their lowered positions after they have been elevated the springs 49 are provided, the top or upper ends of which are connected to the arms 32 and their lower ends connected to the standards 1 and 2.

It will be understood that the teeth 50 formed upon the bars 41 should be located so that when the heads 40 are moved upward the points of the teeth will engage the ends of the column or pipe but when the heads are lowered by the action of the springs 49 the teeth will slide upon. the ends of the pipe or column.

For the purpose of preventing any back action of the pipe or column after the same has been moved by the heads 40 the grooved heads 51 are provided, which grooved heads are rigidly connected to the arms 52,'which arms are loosely mounted upon the rock shaft 35. The grooved heads 51 are provided with toothed bars 41 which are similar to the toothed bars 41 located in the heads 40.

It will be understood that the heads 40 and 51 are curved to correspond substantially with the curvature of the column, or pipe and the toothed bars 41 and 41 correspondingly curved.

it will be understood that the arms 52 should be loosely mounted upon the rock such a width that the ends ofthe columns or -pi-pes can be properlyinserted in the grooves wand the extreme ends of thepipeseated n'againsttoothedbars 41 and 41.

Another -object in. forming. the. grooves of a width greater than thethickness of the metal composing the column or pipe is to allow the fluted or finished pipe, or the ends thereof to vmove through the. grooves formed in the heads 40 and 51.

It will be understood that the head 22 must necessarily move in opposite directions and consequently the power shaft 4must be shifted as to its d rection of the rotation simultaneously or practically simultaneously with the shifting of the direction of the mo tion of the head 22 and consequentlymechvanism must-be employed to shift the clutch 8 so that it will alternately engage the open and cross belt power wheels 5, and in order to provide for this action the reciprocating bar 54 is provided, which bar is held in proper position by means of the brackets 55, whichbrackets are connected to the tie bar 3 or its equivalent. Upon the reci rocating bar 54 are located the knocker-b ocks 56, which knocker-blocks together with the reciprocating bar 54 are actuated by the bar '26 carried by thehead 22. The reciprocat- -=ing bar 54 is pivotally attached to the bellcrank 57, to which bell-crank is pivotally at tached the clutch operating bar 58. The bell crank 57 is properly connected to the bracket 59 orits equivalent, which bracket is connected to theproper standard.

The-mechanism just above described is of no importance so far as its detailed con- :struction is concernedas it will be understood that other mechanism may be employed to shift the clutch 8 without depart- 1n from the nature of my invention.

It will be understood that on one side of the standard 2 should be located the support or post 60, which post carries one end of the power shaft 4.

It will be understood that the forming roll 24 can be varied as to shape but I prefer to employ different rolls for different kinds of Work.

For the purpose of providing a means for varying the distance between the flutes or corrugations or to provide for different widths or flutes the links 38 and 39 are adjustably attached to the arms 36 and 37 so that the bottom or lower ends of said links I can be adjusted to or from the rock-shaft 35 by which arrangement the movement of the heads 40 is increased or decreased reference being had to the distance the links 38 and 39 are set from the rock shaft 35.

For the purpose of supporting the heads 52 in the desired adjustment the bar 61 is proing the forming ro lvided, Which-bar is attachedwto the end standard '2 andais held-inl place bywsuitable bolts 62.
