GROOVlNG-MACHINE.
SPECIFICATION forming-part of Letters Patent No. 718,968, dated January 27, 1903. Application filed May 9,1902. Renewed December 29, 1902. Serial No. 187,065. (No model.)
To rut whom it may concern! Be it known that I, AUGUSTUS VALORUS ALLEN, a citizen of: the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Grooving-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to groovingmachines, and particularly to such. machines used in connection with a mandrel for seam ing and making tubes of metal, such as stovepipes.
The machine is of that class in which a grooved wheel is carried back and forth on the blank'upon the mandreh' Theobject of the invention is to construct a machine having several grooving-wheels, any one of which may be used, according to the width of the groove desired.
A further object of the invention is to form sure on the-blank maybe regulated and the machine adjusted toallow for various thick nesses of material. a
A further object is to generally simplify and improve the construction of such maj the line 3 3 of Fig. 2.
chines. a A
In the accompanying drawings, Figure 1 is a perspective view of the machine. Fig. 2 is a cross-section thereof. Fig. 3 is a section on The machine.- includes three groovingwheels set in the same frame and adapted to be carried back and forth upon the mandrel by direct hand-power applied .to the frame,
one of the wheels bearing onthe work and the other two against'a parallel guide-arm above the mandrel.
In the drawings the mandrel is indicated at,
6, above which is the parallel guide-arm 7, whichhas on its under side a longitudinal groove '11, forming a track for the wheels.
The mandrel and arm may becast in one piece or cast separately and bolted together,
as desired.
The grooving-wheels are indicated at 8, having grooves .8 in the periphery thereof, such grooves being preferably of difierent widths. The carriage carrying the wheels consists of side plates 9, which are preferably circular, 'joined by bolts 10 and spaced apart by sleeves 11 on the bolts. bored radially to receive, at a snug fit, stems 12 which, project beyond the plates, where, bearings are formed for the axles 8"of the wheels. The axes of the wheels are at the points of a triangle equidistant from the center ofthe plates. The inner ends of the stems 12 areconical, as at 12", andimpinge against conical shoulders 13, formed in a shaft 13, which extends through the center of These plates are the plates and through one of the handles 14,
where its outer end is provided with a binding-nut 13". The inner end of the shaft is reduced and threaded to enter a threaded bore 14, formed in the opposite handle.
The conical shoulders on the shaft 13 act as wedges to force out the stems 12, and con sequently the grooving wheels, when the shaft is moved in the appropriate direction longitudinally. direction allows the wheels to be drawn in. When set as desired, the adjustment is fixed by the binding-nut 13".
In operation the device is placed with one wheel bearing on the mandrel and two wheels on the guide-arm and is thus rolled back and.
forth upon thework. Any one of the wheels may be used upon the work by turning the device around. I
' What I claim 'is- 1. The combination with amandrel and a parallel guide-arm, of a carriage having several grooving-wheels one-of which'bears upon the mandrel and others of which form bearing-rollers against the arm. v L 2. The combination with a mandrel and a parallel guide-arm, of a groover comprising a carriage, a plurality of grooving-wheels car ried thereby part of which bear on the mandrel and part on the arm, and means to ad- Movement .in the opposite justably spread the grooving-wheels with respect to each other.
3. The combination with a mandrel "and a parallel guide-arm, of a groover working between the mandrel and arm comprising a -frame, and grooving-wheels carried thereby radially adjustable 'from a common center.
4:. In a groover, in combination, a carriage having radially adjustable stems .therein, and grooving-wheels journaled at the outer endsof the stems.
5. In a groover, in combination, a-carriage, a laterallyadjustable shaft therethrough having-inclines, and radial bearing-supporting stems resting upon the inclines whereby lateral movement of the shaft will meve the stems radially, and grooving wheels journaled in the bearings;
- 6'. The combination with a mandrel and a 'parallel guide-arm, of a carriage, having several grooving-wheels, revoluble to present each of said wheels to the mandrel and the other wheels tothe guide-arm toform bearing-rollers. I I 7.- The combination with'the mandrel and arm, of the -reciprocating carriage having an adjustable grooving-wheel and'bearing-rollers, handles on each side'of the carriage to move'the same, a screw connection between the handles, and means actuaw by the screw to adjust the wheel.
8. The combination in a groov erof the carriage, the grooving' wh-eels carried thereby, the handles on each side of the carriage; the screw shaft connecting the handles, and
wedge means actuated by the shaft to spread the grooving-wheels.
In testimony whereof I affix mysignature in presence of two witnesses. I v AUGUSTUS VALORUS ALLEN.
