@LARENCE W; CARTER, OF MINNEAPOLIS, MINNESOTA PROCESS 0]? LOADING MOLDS WITH MOLDIITG MATERIAL.
Specification of Letters Patent.
Patented May .11, 1909.
Application filed August 9, 1904. Serial No. 220,080.
To all whom it may concern:
Be it known that I, CLARENCE W. (ian'rnn, citizen of the United States, residing at Minneapolis, in the county of Hcnnepin and State of Minnesota, have invented certain new and useful Improvements in Processes of,
Loading Molds with Molding' 'Material; and
I do hereby declare the following to be a full,
.l lever 15, as shown,
clear, and exact descri tion of the invention, i
such as will enable ot ers skilled in the art to which it appertains to-rnake and use the same. an improved process of loading mo ds with molding material properly compacted for molding, and to the above ends it consists of the novel actions, and nani ulations, here,- inafter described and de'fine in the claims. Figure 1 is a view principally in side elevation, but with some parts sectioned and with some parts broken away, illustrating one form of apparatus by means of which my improved process may be carried into effect; Fig, 2 is-a transverse vertical section takcn approximately on the line of w of Fig. 1.
The numeral 1 indicates the floor of the second story of a building, in which the apparatus is shown as installed. I a
The numeral 2 indicates a mold which, as shown, is supported by a table 3.
The numeral 4 indicates a supply hopper, which contains the molding material.
The numeral 5 indicatcs a fan, which, as shown, is supported by brackets 6 in an clcvated position. This fan is provided with an air trunk 7 which extends horizontally for some distance, and'thcn is turncd vertically downward, and is passcd through lhc floor 1. To the dcpcnding cnd of this trunk 7 1s pivotally, or othcrwisc l(-) i.s( l attachcd 'a tubular discharge nozzle 8, that mmmdiatcly overlies the mold 2, and tcrminatcs some considerable distance above thc same.
l/Vorking within the supply hoppcr 4-, is a feed screw 9, the shaft of which projects at one end, and is providcd with a friction wheel 10. The bearing for thc inner cn,d of the scrcwf) is cut away at l l, to afford a. passage through which the matcrial to be molded may be forced from tho hoppcr, into the air trunk 7, under thc action of the screw 9.
Pivoted in bearings ill on tho floor I, is a bell crank lever 13, the upper arm of which shown as bifurcated, and the lower arm of which is conncctedxby a link 14 to a. long l secured beneath the 001' 1. The free end of this lever 15 is connected by a depending link 17 to a foot lever 18 which, as shown, is
ivoted to the lower portion of the table 3, in position where it may be readily engaged by the foot of the operator, standing close to the mold 2. In the bifurcated arm of the bell crank 13 is loosely journaled a shunt shaft 19 which carries a small friction wheel 20 and a pulley 21. A friction wheel 20 is I adapted to be pressed into frictional contact My-mvention has for its object to )rovide with the friction wheel 10 of the feed worm 9, through the lever connections described,
by a downward pressure a plied to the foot lever18. A power driven liclt 22, shown by dotted lines, runs over the whey 21 to im-- part continuous motion to t e shaft 19. By varying the pressure on the foot lever 18, frictional contact between the friction wheels pivoted to abearing 16 10 and 20 may be varied so as to vary the speed and feeding action of the feed screw 9'.
When the fan 5 is set in motion, feed screw 9 is driven, the material to be molded will be blown, or shot, as it were, out from the lower end of the nozzle 8 and into the mold 2, under high velocity, and hence will be compacted within the mold by momentum, and without requiring tampmg or pressure from any other source. By proper adjustments of the nozzle 8, the material to be molded may be )roperly distributed within the mold. It will be understood that the material to be molded is relieved from the air pressure before it reaches the mold, and
' is injected into the mold under the velocity which is acquired while subject to the pressurc of the elastic fluid within the air trunk.
llcncc the air. or other elastic fluid used to impel the material to be molded, does not disturb the material which is once delivered and the into the mold, and has no tendency to blow the same out of the mold.
This proccss is cspecially adaptcdfor use in forming; concrete buildinc blocks within molds. the concrete or ccmcnt, in plastic condition, is placed within the hopper 4, and is blown, under momentum, or shot. into, the mold 2 in the manner previously described. With the dclivcry cut of the air trunk turned vcrtically dowmvard, gravity is caused to assist thc mcnmatic forcc in imparting: momentum to tho molding matcrial which is injected or shot, into the mold. It will, of course, be understood that any In thc construction of these blocks,

molding material within. the mold and replish the ideal result.
the molding material within the mol under suitable elastic fluid, under pressure; or ,in other words, that any pneumatic force, in l be utilized to impart the rec uired momentui 1 to the molding'material. t also, of course, follows that a neumatic blast, or elastic fluid blast, may e supplied by any suitable device. 1 i t The above described process makes it possible to construct concrete building blocks, and other molded objects, with great rapidity and economy.
It is Well known that in forming concrete blocks or in compacting other molding material within molds, it is very desirable that such material should be of the same or of some definite density throughout. In thel usual attempt to approximate this result, it 1 has been customar to repeatedly place peatedly tamp the same, but this is a slow and consequently an expensive operation, and even when carried out does not accom- The ideal result is the simultaneous delivery and tam ing of which manipulation the molding material is or may, as is obvious, be evenly com- This ideal iesult I accomplish by my improved process above described. The moldin material, by the blast, is delivered with suc force that it ters Patent of the United States is as fol- 1' lows:
l. The process of load ng molds with *molding material, which consists in produc ing a confined pneumatic blast, in introducing the moldin" material into tliesaid conlincd blast, in shooting the said molding material into the mold, under the impclling force of said blast, and in varying, the direction of the blast to distribute the said moldinp material within the mold, whereby the said molding material is tamped simultmiwus with its delivery.
2. The process of forming, (mm-rote blocks in molds, which consists in producing a conlined pneumatic blast, in introducinp plastic concrete into the said confined 'blast, in shooting said plastic concrete into the mold, under the impellin n force of said blast, and in varying the direction of the blast to distribute concrete within the mold.
