Description
Jan 6, 1931. 4 c. JACKSON v 1,787,529
MOLDING APPARATUS Filed Jan. 25,1950
INVENTOR fan/WW Jam/mm Patented Jan. 6, 1931 CORWILL JACKSON, OF CHICAGO, ILLINOIS MOLDING APPARATUS Application filed Jamiary 23, 1980. Serial No. 522,819.
My present invention is especially designed by me for use in practicing the method described and claimed in my application for Letters Patent filed Japuary 10, 1929, Serial No. 331,668, and more specifically to an apparatus in which the intensity of the vibrations may be varied throughout a wide range without varying the frequency and without stopping the vibrating unit.
The main objects of this invention are:
First, to provide a molding apparatus the intensity of the vibrations may be varied with the apparatus in'operation. v c Further objects, and objects relating to details and economies ofmy invention will definitely appear from the description to follow. The invention is defined in the claims. I so A structure which embodies the feature of my invention is clearl illustrated in the accompanying drawing, in which Fig. 1 is a transversevertical section on a line corresponding to line 1-1 of Fig. 2 of an apparatus embodying the features of my I invention.
Fig. 2 is a .side elevation, the hanger supporting shafts being shown in section.
Fig. 3 is an invertedview of the vibrating 4'0 motor and its support, the clamps being omitted and the 'motor housing being partially broken away.
Fig. 4 is aside elevation of another embodiment or adaptation of my improvements, the form being mounted on a table instead of suspended as shown in Figs. 1 and 2.
In the embodiment illustrated in Figs. 1
and 2 the form 1 is supported by flexible hangers 2 suspended from drums 3 substantially as shown in my application for Letters Patent Serial No. 413,981, filed December 14, 1929. The details of the suspending means, other than that they are flexible, form no part of my present invention.
I provide means for vibrating the form 5i or mold and for varying the intensity of the vibrations without varying the rate of vibrations. The vibrating unit in the embodiment illustrated consists of a motor designated generally b the numeral 4 having an unbalancing weig t 5 on its shaft 6.
The yoke-shaped support 7 is detachably secured to the form by means of the form engaging clamps 8 connected by the adjusting rod 9 having a crank 10 at one end. The motor is mounted on a flexible hanger 11 con nected at one end to the arm 12 of the support and at the other end to a link 13 pivoted at 14 adjacent the arm 15 of the yoke. The adjusting screw 16 is pivoted to the outer end of the link at 17 and projects through the arm 15 to receive the adjusting nut 18 provided with a hand wheel 1 Thus arranged the flexible motor hanger 11 may be tensioned, that is, -tightened 'or loosened, with the result that the intensity of the vibrations may be varied through a very wide range. The tightening of the mem ber 11 increases the intensity of the vibrations and loosening it decreases the intensity of the vibrations. This is of material advantage in molding building blocks and panels where there is a variation in the character of thejaggregate employed in facing, or where colored facingsare employed with uncolored body 8 portions. The vibrations may be accurately gauged so asto prevent displacement of the facing material into the body material as might result if the vibrations were too intense. It is, however, desirable tomaintaln a highand uniform rate of vibration throughout the variation of the intensity of =vibrations.
My improved molding apparatus is therefore very readily adapted to mcetthe particu- 5 larconditions or material operated upon. It is especially desirable for use with flexible hangers for the mold but may be very advantageously used where the mold is placed upon a solid table or bed 20 as shown in the i with an unbalancing weight, a yoke-like support provided with means for detachably mounting on a form, a link pivotally mounted on said support adjacent one arm thereof, a flexible hanger for said motor connected at go its ends to the other arm of said support and to said link, an adjusting screw pivotally connected to the outer end of said link and disposed through the adjacent arm of said support, and an adjusting nut on said screw eng5 gaging said arm.
2. In a molding apparatus, th'e'combination of a motor provided with an unbalancing weight, a yoke-like support provided with form engaging means, a link 'pivotally mounted on said support adjacent one arm thereof, a flexible hanger for said motorconnected at its ends 'to the other arm of said support and to said link, an adjusting screw pivotally connected to the outer-end of said as link and disposed through the adjacent arm of said support, and an adjusting nut on said screw engaging said arm.
' 3. In a molding apparatus, the combination of flexible form hangers, a motor pro 40 vided with an unbalancing weight,.a support provided with form e ngaging means, said support having a -member adjustably mounted thereon, a flexible support for said motor connected at one end to said support and at the other end to saidadjustable-member thereon, and an adjusting screw for said adjustable member of said support.
4. In a molding apparatus, the combination of a motor provided with'an unbalancing 5 weight, a support provided with form engaging means, said support having a member c .adjustably mounted thereon, a flexible support for said motor connected atone end. to

5. Inan apparatus of the class described,
the combination of a flexible form hanger, a
support rovided with a form engaging clamp, a exible motor hanger connected at its ends to said support, and a motor provided with an unbalancing weight mounted on said motor hanger intermediate its point of con- 05 nection to saidsupport.
the combination i 6. In an a paratusof the class described, the combinatlon of a support rovided with a form engaging clamp, a exible motor hanger-connected at its ends to said support, the connection for one end being adjustable, and a motor provided with an unbalancing weight mounted on said motor hanger intermediate its point of connection to said support.
7. In an apparatus of the class described, the combinationwith a flexible form hanger, a motor provided with an unbalancing weight, a support adapted for mounting on a form, a flexible hanger for said motor mounted at its ends on said support, and means for tensioning said flexible motor hanger.
- '8. In an apparatus of the class described,
the combination with a support provided with form engaging clamps, ofa flexible hanger mounted on said support, means for adjusting the tension of said hanger, and a vibrating means mounted on said hanger in termediate its ends.
, 9. In an apparatus of the class described, the combination of a support provided with form engaging members and having a flexible vibrating unit hanger connected at its ends thereto, a vibrating unit mounted on said flexible hanger intermediate its ends, and means for varying the tension on said hanger while the vibrating unit is running.
