TILE-MAKING MACHINE Application filed October 19, 1927. Serial No. 227,224.

This invention relates to machines employed in the use of the manufacture of dram tile T and Y connections and has for a prin-.

cipal object to provide a mandrel adapted to receive a section of hollow tile in its plastic condition, associated with which is a plunger frame carrying the shank section of the tile formed in a relatively hardened condition and adapted through the operation of the apparatus to force one end of the shank through one side of the tile, thus causing an opening to be cut in the tile'about which the shank is securely welded or attached upon the drying of the tile.

Another object of the invention is to provide a locking lever for the mandrel, which when secured in locked position operatesto throw a clutch mounted on the machine arranged for controlling the movement of the plunger frame whereby to cause the operation of the same. 7

A still further object is to provide means for automatically disengaging the clutch at the completion of the shank attaching 'action of the plunger frame so as to throw the same out of operative position.

An additional object is to provide an apparatus of this character of simple and practical construction, eflicient and reliable in performance, enabling the shank section of draintile of this characterto be formed in position on the tile in a uniform manner so that the finished article will be of .an

identical formation, which is inexpensive to manufacture and operate and otherwise well adapted for the purposes for which the same is intended.

Other, objects and advantages reside in the special construction and combination of the various elements comprising the invention,

reference being had to the accompanying drawings, wherein Figure 1 is a side elevational view.

Figure 2 is an end elevational view.

Figure 3 is a top plan view.

Figure 4 is a view in elevation, with parts shown in section of-the shank carrier for the plunger frame.

Figure 5 is a side elevational view of a complete T tile constructed through the use of our invention.

Figure 6 is a group view of the shank and tile section shown in detached relation.

Figure 7 is a longitudinal sectional view through the clutch mechanism taken substantially along a line 77 of Figure 3.

Figure 8 is a detail of the clutch collar operating yoke. I

Figure9 is a detail'of the clutch control rod, and,

Figure 10 is a sectional view taken substantially along a line 1010 of Figure 8 illustrating the automatic clutch release mechanism.

Referring to the drawings in detail, the invention comprises a frame 5 forming a support for the apparatus at one side of which is pivotally mounted a mandrel 6 for horizontalswinging movement, the free end of the mandrel being provided with a handle 7 and having notches 8 formed therein intermediate its end engageable with guide rods 41 attached to the frame whereby to guide the mandrel into the stationary section 10 of a longitudinally split tile mold.

.The opposite section of the mold indicated at 11 is carried on a pivotally mounted arm 12 swingable on the frame in a horizontal planein substantially parallel relation with the mandrel 6.. V Y

The free end of the mandrel and arm 12 are adapted to be secured in locked position by a pivotally mounted handle 13 having a' link 14 attached thereto and operating a bellcrank 15 fulcrumed on the frame and operatively connected with a slidably mounted clutch control rod 16. The rod 16 is inserted through a slotted opening formed in a supporting bracket 17 attached to the frame, the rod being yieldably retained against upward movementby the pin 18 extending downwardly in the slotted opening in the bracket 17 and urged into engagement with the upper edge of the rod by a coil spring 19. 'The under side of the free end of the rod 16 is formed'with a shoulder 20 adapted to engage the end 21 ofia clutch operating fork 22 pivotally mounted at 22' for horizontal swinging movement on the frame.

The opposite end of the fork 22 engages a clutch collar 23 slidably mounted on a drive 7 I.

shaft 24: and retained for rotation there with by a key 25, the movement of the collar in one direction operating to cause the engagement of a pair of clutch plates 26, one

of said plates being carried on a hub 27 and to which a gear 28 is attached The hub and gear are attached to its adjacent clutch plate for free rotation on the shaft, whereas the opposite clutch plate has its hub formed with a plurality of grooves 29 for receiving the fingers 30 formed on the collar whereby to cause the rotation thereof with the shaft.

A coil spring 31 interposed between the collar and the adjacent clutch plate normally retains the same out of engagement therewith. The clutch plates are adapted to be locked into engaged position for positive friction engagement with each other by means of latches 32 arrangedv for movement into locking position by means of rollers 33 slidabl-e upon the periphery of the collar during the movement of the collar into such engaging position. Adjusting screws 34 maintain the rollers 33 in proper engaging position with the collar 23.

A gear 35 mounted on a counter-shaft 36 is operated through the drive gear 28, said gear 35 carrying a crank-pin operatively connected with a pitman 39 and to which is attached a plunger frame 40 having vertically extending guide rods 41 disposed for vertical sliding movement in guides 42 attached to the frame 5.

The upper ends of the rods 41 are providec with a crossarm 43 from which is suspended a punch mounting 44 having an annular collar 45 arranged at its lower end. A punch 46 is carried by the collar with its lower end extending therethrough, and supported upon the upper edge of the collar by means of pins 47 arranged at diametrically opposite sides thereof. A coil spring 48 is interposed between the upper surface of the punch and the mounting 44 yieldably urging the punch in downwardly extended position.

The upper face of the mold sections 10 and 11 are provided with semi-circular notches indicated at 49 combining with each other to form a circular opening in the mold and about the edges of which upwardly extending mold sections 50 are formed. Thus, when the sections 10 and 11 are arranged in engaged position, the same constitutes a completed mold of a T-shaped formation within which the T drain tiles may be fitted.

A cam collar 51 is mounted on the countershaft 36 having a cam 52 formed at one sine Y thereof, adapted during the rotation of the shaft to engage a push rod 53 having its end attached to a bellcrank 54 disposed beneath releasing the end 21 of the forkfrom engagement by the shoulder 20 of the rod whereby to permit the spring 31 to move the collar 23 out of engaged position with respect to the clutch mechanism.

A section of drain tile of substantially cylindrical formation as illustrated in Figures 5 and 6 of the drawing and designated by the numeral 55 may be placed on the mandrel 6 while in its plastic state and asection of tile indicated at 56 adapted to form the shank thereof and having its lower edge movement of the handle 13 so as to lock the parts in engaged position Wlll, as heretofore explained, throw the clutch mechanism intoengagement so as to cause the lowering of the punch frame and move the die mounting carrying the die 46 downwardly through the upper ends of the vertical extensions '50 of the mold so as to engage the collar 45 upon theupper edge of the shank section 56 of the tile and thus press the same against the upper side of the tile section 55. At the same time the punch 46, which is of a slightly less diameter than the bore of the tile section 56 is inserted through said section to cut an opening within the upper edge of the tile section 55. The cam 52 is timed to throw the clutch'mechanism out of engagement upon the return of the punch frame to its uppermost position whereupon the pivoted arm 12 and mandrel may be released from the handle 13 and the tile removed therefrom'. The tile is then per mitted to drywhereupon the sections are permanently sealed together.

It is obvious that the invention is susceptible of various changes and modifications without departing from the spirit and scope of the invention or sacrificing any of its advantages, and we accordingly claim all such forms of the invention to which we are entitled.
