I H. KNIGHT. means FOR MOLDING CEMENT PIPE.
"JPA NfgO-EF C rst memory-11m CITY, NEW. JERSEY Specification; forming part of Letters Patent No. 35,692, dated 'June 94,5921
-; Befit known that HENRY KN GHT, Jer-F sey City, in the icounty' of Hudsonand State of New. Jersey, "have: invented a new and use ful "Improvement (in Machines for Molding Cement Pipes; and'I do hereby declare that the followingis'a full, clear, andrexaet description I of the. same, reference being had to the accompanying drawings, forming part of this specification, in" which- Figure lis ayerticaltransveme sectionofja cement 'molding ma'chine' with my improve.
ments applied to it, p The parts are in opera-j tive position; anda cenient pipe is shown-as molded by the machine. Fig.2 is a'section of the same in a longitudinal direction, the parts being out; o operative position; A cement pipe'is within the mold, and the mold lowered' upon a'truck, readyto be mov'edto. the positionindieated in red lines, in which position it is ready to be lifted out of the machine,
Fig. 31s a'horizontal section ofthe machine in the li'ndwwof Fig; 1. Figs gland-fi are de- 'tailsof the machine. I r o I 3 Similar letters of reference 'in the several figures indicate. corresponding, parts. a e The nature'of' my invention consists, first,in
'the combination of centrally-perforatcd table,
intermediate centrally-perforated and movable platform, adjustable mold-or. flask, adjustable base supporting and centering plate, adj usta-' ble'core,"'and 'ajack-screw or its equivalent, all in such manner thata cement pipfdwitha square socket in one-end is produced with out the neeessityfof lifting the niold and pipe above the core; second, in the combination of the foregoing with a railwa'yand' a truck, "so that when the pipe has been: molded it, *whilein the mold, may be lowered upon Y the? truck, clear of the top centering-table, and'run out fromunder the same to a position for being lifted ofl' of the machine; third, 'in the combimold andthenclamping itinzposition; fifth, in the manner'of arranging the guides of the rack of the jack-screw and the grooves of the a frame of the machine so that they control the core, and yetdo not interferewith its up movement; sixth, in connecting the shoulder or base of the core to the 'core'by means of a pinor other adj ustable connection, so that the shoul der may be withdrawn or applied,asnecessity may require; seventh, it consists inia manner of lifting the ba e-plateand the or'inold above the truck-platform. i v I Toenable'others skilled inthe art to make and use niy invention, I will proceed to de ,scr'ibe its construction and operation.
- {A is the frame of the machine. It consists of four upright posts placed on asq'uare block and united by cross-tics and a top-piece or table,'B,whicht-able has a circular aperture through its center. v
4 C is a hollow column extending up'froni the center, of the base-block and uniting with'a strong crosstree, D; of the frame.
"E E are two short. posts mounted upon the cross-tree and extending up and uniting with cross-ties'oftwo railway-bars, F F, which are. firmly bolted to the inner sides of the main posts of the frame A. The posts E E are grooved from top to bottom ,on' their inner sides, so as to "admin steadying' and "guiding tongue's'of thejaek-screw;
1G isja 'T- shaped rack-bar, arrangedsb as" to rise and descend in the hollow column and fitted and steadied, so as to move truly, by means .of tongues or guides a athereof, between, the
grooved posts BE. 7 a v His a piniomand Ha friction-roller; The
' l'ormer is arranged in frontand the latte'r behind the rack-bar. One givesniotion'to the rack-bar by gearing with it and the other eases it's' up'and down movements. The pinion-is on a crank-shaft, H", which is boxed on topof the cross-tree. v 1 ,l I I is a core of cylindricforni mounted upon 'thenpper end of the rack-bar, -Tlie base of =this core is enlargedin diameter byuneans of acylindric collar, J, placed-around it'and fastened by a through-pin, b,\vhi'clij can be readily withdrawn as its ends protrude. 'The upper surface of this collar is made pliable by being faced with a soft -leatl1cr, rubber, or metal same diameter as the collar J of the corel is cut.- -'-1o the upper side of this base board or plate two flaps, d d, are hinged, said flaps having undenbeveling semicircular recesses e '8 formed in their meeting edges. These recesses. when united form a circle equal in circumference to the outer circumference of the flask or mold at its base or largest diameter.
M is a mold or desk of ordinary construction, being divided vertically into two parts and made with two difl'erent diameters, s t, soas, inconnection with the collared core, to. mold pipe with extending collars and inner square sockets or shoulders. This mold rests vertically upon the base board or plate, andis centeredconcentric with the aperture therein by means of the flaps d d and confined in that condition bythe same. Afurther centering is efi'ected by means of the circular aperture in the top or table B,whcn the; parts are adjusted for receiving the cement into the mold in -the following manner: The mold being placed and confined upon the base'plate or board, the truck is run in under the table until the circumference of the smaller portion of the mold is concentric with. the aperture in the table. The jack-screw G H is now caused to elevate the core until its collar J enters the mold or flask the distance, of the desired depth of the socket to be formed in the cemopposite points, and by reason of the further operation of the jack-screw they elevate the base-plate and mold 0d of thetruck and cause theupper end of the mold to enter the central aperture of the ,table B till its edge j comes even with the top surface of said table,
as illustrated in black in Fig.1. In this conditionof the parts the cement is introduced from thetable B into the mold and compactly forced down around the core. When the mold been filled-and a --striker" applied to the upper part of the molded cement pipe, 2. narrow ring-collar is forced down into. the ceme as shown at f, so as to form a narrowshoulder at the small end of the pipe. The pipe is now finished, and after being allowed to set"-sufficiently the jack-screw is operated so as to withdraw the core gently. As the core descends the pliable washer peels off from the cement at the place where the sguare shoulder is formed, and thus saves the shoulder from strain and injury. With the descent of the core the mold and pipe and base board or plate also descend and rest upon the platform-truck. The core having cleared the-mold and the mold having cleared the table B, the truck is run out on the raiL way-bars, the flaps raised, and the cement pipe within the mold is removed from the machine. Another mold is-brought into use and, adjusted to the machine in the same manner as previously described.
With my invention pipe with square sockets at one end and also extending collars are molded, and by modifying the form of the .moldand the core pipe with square sockets simply at amend and square shoulders at the other end may be produced; or, if desirable,
ject very slightly may be produced by reducing the larger diameter of the coreand the larger. diameter of the mold and using the ring-collarf to form a shoulder on the outer per end of the cement pipe. I, however, prefer pipe with collar and socket, such as represented.
What I claim as my invention, and desire to secure by Letters Patent, is- I 1. The combination of the table B, movable platform L, mold or flask M, plate K, core I, and jack-screw G H, or its equivalent, the whole constructed and arranged and operating substantially as and" for the purposes described.
2. The combination of the wheeled truck L and railway-bars F F, with'a cement-pipemolding machine, substantially in the manner and for the purpose described.
3. The combination of the pliable washer with the hard shoulder of'the core, substantially as described, and for the purpose set forth.
4.. The construction of the plate K with flaps d d and with apertures of different diameters, substantially as and for the purpose described.
5. The manner of arranging the guides a and the short posts E E with the rack-bar G and core I, for the purpose set forth.
'6. The connection of the shoulder or collar J to the core I by means of an adjustable through-pinyb, in'the manner and for the purpose described.
7. The lifting ofthe base-plate K and the flask or mold above the truck-platform by means of the ends of the'pin b, or an equivalent means, substantially as described.
HENRY KNIGHT.
