JOHN ELDER, OF CORONA, NEIV YORK.
PlPE-REAMING DEVICE.
SPECIFICATION forming part of Letters Patent No. 765,133, d e July 12, 1904. Original application filed October 21, 1902, Serial No. 128,103. Divided and this application filed February 9, 1904. Serial To all whom it may concern.-
Be it known that I, JOHN ELDER, a citizen of the United States, residing at Corona, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Pipe-Beaming Devices,
-of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
The object of this invention is to provide an improved device for reaming pipes or the ends thereof; and with this and other objects in view the invention consists in a device or tool of the class specified constructed as hereinafter described and claimed.
This is a divisional application based on an application for Letters Patent of the United States filed by me October 21, 1902, Serial No. 128,103, and the invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which- Figure l is a side view of my improved pipe-reaming device or tool; Fig. 2, a plan view thereof; Fig. 3, a central vertical longitudinal section on the line'3 3 of Fig. 2; Fig. 4:, an inverted plan view of a locking-plate forming part of my improved pipe-reaming device or tool; Fig. 5, a section on the line 5 5 of Fig. 1, and Fig. 6 a plan view of a clamping-jaw forming part of the tool.
In the practice of my invention I provide a stock or frame a, which is open centrally and provided at the top with parallel members or guides a and at the bottom with a depending tubular portion (0 in the bottom of which is secured a collar (6 The ends of the stock a are provided with tubular members a adapted to receive the screw ends a of handlepieces a and by means of which the tool may be turned in the operation thereof, as hereinafter described. The central portion of the stock or frame a is open between the parallel members or guides a to correspond with the tubular depending member a and formed at the opposite sides of said opening and between said parallel members a are rectangular spaces (N0 model.)
or chambers a adapted to receive jaws 7), a plan view of one of which is given in Fig. 6 and two of which are shown in section in Fig. 8. The jaws I) are provided with openings 6 through which are passed bolts 0, the lower ends of which are screw-threaded and screwed into the stock or frame, and said bolts are of less diameter than the openings 6 The stock or frame a is also provided at the opposite ends of the member a with keepers 0 through which are passed screws 0 by means of which the jaws I) may be adjusted. The jaws b are of the same shape and size, and said jaws are shown in position for use in Fig. 3, and said jaws are provided at their inner ends with downwardly-directed portions 5 so as to provide greater surfaces for holding a pipe to be threaded, one of which is indicated in dotted lines at f in Fig. 8. The parallel members or guides a which hold the jaws b in position, are preferably provided at the opposite ends thereof with raised bearing portions f the tops of which are flush with the jaws b, which aid in holding the jaws b in position.
The bolts 0 in the form of construction shown, the lower ends of which in practice are screw-threaded into the stock or frame a, are provided at their upper ends with two col lars or flanges g and g and the remaining device which I employ, a bottom plan view of which is given in Fig. 4, a transverse section in Fig. 5, and a vertical section in Fig. 3, comprises ahollow cylindrical portion having opposite side bottom plates 9, provided with oblong openings 9 which open outwardly at the opposite sides, as shown at and at the bottom of the plates g the walls of the openings 9 are cut out to form grooves adapted to receive the collars or flanges g of the bolts 0, and when the reamer device proper is placed in position, as shown in Figs. 1, 2, and 3, the flanges g and g of the bolts 0 hold said reamer in place, and at one end of said reamer is an adjustable wedge-shaped plate /L, which is placed between the corresponding top flanges or collars g of the bolts 0 and the body portion g of the reamer, and by moving this plate longitudinally the reamer may be securely locked in position for use.
The hollow cylindrical body portion of the rearner is provided in the opposite sides thereof with vertical slots 72 and passed through the top portion thereof is a screw 78, having a handle-piece It", by means of which said screw may be turned, and mounted on said screw and adapted to be moved vertically thereon by turning said handle-piece is a tubular casing h provided at its upper ends with radially-arranged keepers 72/, and said tubular casing is also provided with verticallyarranged keepers 707, as clearly shown in Fig. 5, and in these keepers it and /1. are placed triangular and radially-arran ged cutter-blades 7L8, which are held in place by a band It, screwed onto the lower end of the tubular casing h, and the cutters it are provided with radial lingers or members 91, which move into the slots 7& in the body portion of the reamer. It will be apparent that by turning the screw ]L3 the cutters b may either be raised or lowered, thereby adapting the device to pipes of difi'erent diameters, as will be readily understood.
When the parts are in proper position and properly adjusted and the pipe inserted, as indicated in dotted lines at f in Fig. 3, the tool may be turned so that the blades it will ream out the end of the pipe, as will be readily understood, and in practice the pipe is held stationary in the usual manner and by any preferred device or devices, and by adjusting the jaws b and the cutter or reamer proper larger or smaller pipes or the ends thereof may be reamed, as will be readily understood.
The entire device is simple in construction and operation and perfectly adapted to accomplish the results for which it is intended,
and various changes in and modifications of the construction herein shown and described may be made without departing from the spirit of my invention or sacrificing its advantages.
Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is
1. The herein-described pipe-reaming device, comprising a stock orframe having radially-adjustable jaws, a detachable reamer mounted over said jaws and comprising a casing having a vertically-arranged screw passed therethrough, and radially-arranged triangular cutters connected with said screw and adapted to be moved vertically by the turning thereof, substantially as shown and described.
2. A pipe-reaming device, comprising a stock or frame having handles at its opposite ends and a central vertical opening, radiallyadjustable jaws mounted in said stock or frame around said opening, a casing detachably connected with said stock or frameover said opening and jaws, and radially-arranged cutters mounted in said casing, substantially as shown and described.
In testimony that I claim the foregoing as my invention 1 have signed my name, in presence of the subscribing witnesses, this 1st day of Feburary, 1904.
JOHN ELDER.
