CORE REMOVER.
Application led September 9,1922'. Serial No. 587,131.
To all 'whom t may con/cem:
Be it known that I, HARRY E. EASTERD'AY, a citizen of the United States. residing at Martinsburg, in the county of Berkeley and State of West Virginia, have invented a new and useful Core Remover, of which the following is a specification.-
This inventionv relates to a machine for removing cores from lengths of pipe, after the pipe has been molded.
The primary object of the invention is to provide a machine of this character which will facilitate the removal of the usual sand core, and at the same time polish the inner wall of the pipe to the end that the pipe will be in condition for immediate use.
Another object of the invention is to provide suction controlled means 'for removing particles of sand from the pipe which may be dislodged 'from the wall of the pipe by lthe brush, forming a part of the machine.
With the foregoing'and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that 'changes in the precise embodiment of the invention herein disclosed, may be'made within the scope of what is claimed, Without de arting from the spirit of the invention.
eferring to the drawings:
Figure lis a plan view of a core removing machine constructed in accordance with the invention. Y j Figure 2 is a sectional view taken on line 2-2 of Figurer l. Figure 3 is a sectional view taken on linev 3-3 of Figure 1 and Figure 4 is a sectional view taken on line. 4 4 of Figure 1. V v
Referring to the drawings in detail the device embodies a frame indicated generally by the reference character 5, which frame includes side rails 6 which are connected as by means of the cross bars 7 disposed adj acent to the ends of the flange, and the 'cross bars 8, disposed intermediate the ends of the frame. K
Supported at one end of the frame is the cylinder 9 which has communication with a suitable source of Huid supply, as through the pipes 10, the exhaust from ,the
cylinder being carried off through the pipes lllwhich' also are in communication with the cylinder.
The valve controlling the operation of the piston 12, which operates in the cylinder 9 includes a relatively long rod indicated at 13 which rod is mounted in bearings 14 and 15 to reciprocate with the piston rod 16 to be hereinafter more fully described. The
exhaust valve casing isindicated at 17 andv is formed with suitable'passage-ways communicating with pipes 11. This valve rod 13 isv formed with grooves 18 that are alternately brought into registry with the pipes 11 to establish communication between pipes 11 and the atmosphere to exhaust the spent tiuid from the cylinder.
The bearing A15 is constructed to provide a valve chamber through which the incoming fluid passes on its entrance to the cylinder 9, the same being directed to one end of the cylinder while the valve casing 19 which is in communication with one of the pipes 10, admits fluid. to the opposite end of the cylinder 9 at predetermined intervals.
Grooves 2O and 21 are formed in the valve rodv 13 which vgrooves are brought into registry with the intake pipe to admit fluid to the cylinder 9, the grooves being arranged so that vwhen one groove is in a position to admit fluid to the cylinder 9, the opposite groove is out of registry with its intake pipe to the end that fluid is admitted tov the operation of the valve elements, in a y manner described. Thus it will be seen that as the piston rod moves within its cylinder, the operation of the valve rod is automatically controlled to regulate the passage of fluid to and from the cylinder 9.
The frame is formed with guideways indicated aty 25 in which the carriage 26 operates, the carriage 26 including cross arms l27 formed with bearings 28 that accommodate the hollow shaft 20, coupling 3() and rod 16. The coupling 30 has an eX- tension 31 to which the hose 32 may be connected, the hose `being in communication with the interior of the hollow shaft 29.
In order that the rod 16 will reciprocate with the couplin 30,A a set screw 35 1s pro-4 vided and exten s through the cross arm 27 associated with the rod 16 to bite into the rod 16 and secure the rod to the carriage.
A swivel joint is indicatedv at 33 and cpnnects the hollow shaft 29 with the'- coupling 30, which in turn has connection with the -piston rod 16 so that the shaft 29 may be reciprocated and at the same time rotated to accomplish the purpose of the invention.
This coupling includes a sleeve 30 positioned over the coupling 30, anda sleeve 31 positioned over the shaft 29 the sleeve 31' being secured against rotation with respect to the shaft 29 by meansof the set screw 32.' An extension 33 forms a part of the sleeve 31 and is disposed within the sleeve 30, packing being positioned between the sleeves `30 and 31 to insure a fluid-tight connection therebetween.
The sleeves 30 and 31 are secured tol gether by means of the bolts 34 that extend through suitable openings formed therein. Supported on the hollow shaft 29 i's a pulley 34: which is keyed to the shaft and which transmits rotary motion to .thef shaft, througha belt and power device, not shown.
Disposed at one end' of the shaftV 29 is a bit 35 formed with teeth 36 that are d esigned to^dig into the sand core filling the pipe section under operation, openings 37 -beingformed inthe bit to allow sand dislodged'by the teeth 36 to be drawn into the hollow shaft 29. Operating in proximity to the bit 35 is a wire brush 38 designed to contact with the inner surface of the pipe under operation to-` remove any particles of sand which may adhere to the inner wall of the pipe under operation.
Inthe use 'of the device, a supporting frame which i's indicated at 40 isv disposed adjacent to the bit 35, which frame supports the pipe under operation, the pipe being indicated at41, suitable means not shown beingprovided on the support for clamping the pipe under operation thereto.-
The pipe under operation is placed with one end thereof adjacent to the bit 35, where upon-fluid is admitted to the cylinder, to
the endthat thepiston 12 is driven into theA pipe. Simultaneously with the movement of the bit through the pipe, the shaft 29 and its bit, are given rotary movements to the endthat the rotating bit is driven throughthe pipe of its outward movement, the arn`r22- contacts with thecollar 24 with the result that lthel rod- 1'3 is moved to' bring the opposite intake port of' the valve housing into communication with the cylinder 9 tothe end that the piston 12 is moved in the opposite direction, withdrawing the bit from the plpef Having thus described the invention, what is claimed as new is 4 In a machine of the class'- described, a frame, a'cylinder at one end of the frame, aI rod carrying a piston movable in the cylinder, a coupling supported at one end of the rotating the shafts.
tifollows that as Dthe bit reaches the limit j In testimony that I claim the foregoing as 'I my own, I have hereto aiiixed my signature in the presence of two witnesses."`
