VINCENT I-I. SOISSON, OF CONNELLSVILLE, PENNSYLVANIA.

Application 1ed40ctober 11, 1917.

To all whom t may concern.'

Be it known that I, VINCENT H. SoIssoN, a citizen of the United Sltates, residing at Connellsville, in the county yof Fayette and State of Pennsylvania, have invented a new and useful Machine for Making Silica Brick, of whichlthe following is a specification. i

This invention relates to machines for making silica brick.

Bricks of this character have heretofore been produced by Vfirst hammering the material into a mold so as to pack all corners oi the mold in order to produce a brick of the proper finish. This has been a laborious and expensive undertaking and `it is an object of the present invention to provide mechanism which will handle the material automatically, thus increasing` the output and lessening the cost of production.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement 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, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has" been shown.

In said drawings Figure 1 is a central longitudinal section through the machine.

Fig. 2 is a side elevation thereof.

Fig. 3 is an elevation of the mold mechanism.

Fig. 4 is a section on line A-B Fig. 3.

Fig. 5 is an elevation of a modified form of mold tapping mechanism.

Fig 6 is a section on line C-D Fig. 5.

Referring to the figures by characters of reference 1 designates a structure support ing a hopper 2 the inclined bottom 3 of which leads downwardly to a ledge 4 extending into the hopper and constituting acontinuation of a guide 5. An opening 6 is provided in the bottom of the hopperl and above the ledge 4 and mounted for movement in this opening is a plunger 7 connected to an actuating rod 8. This rod carries an anti-friction roller 9 and a weighted cord 10 or the like connected to the rod 8 serves to hold the plunger 7 normally retapping Specification of Letters Patent.

tracted into the opening 6. This weighted cord is mounted on a. pivotal guide sheave 11 as shown.

The hopper is divided by a vertical partition l2 into two compartments 13 and 14 respectively. The inclined bottom 3 is arranged under the compartment 13 and the partition l2 terminates above the inner end of the ledge 4 and practically in horizontal alinement with the upper wall of the opening 6. A plate 15 forms the bottom of the compartment 14 and has an outlet opening 16 therein the walls of which converge downwardly. A tamping rod 17 is mounted for reciprocation within the compartment 14 and has a foot 18 at its lower end while its upper end is slidably mounted within a bracket 19 connected to a beam 20 pivotally mounted as at 21 above the hopper 2. A spring 22 is mounted on the rod and constitutes a cushioning means for transmitting motion from the beam 20 to the rod 17 during the downward movement of the beam. This spring is interposed between bracket 19 and a collar 22 secured to or formed `on the rod 17.

A table 23 is arranged under the hopper and is spaced from the plate l5 a distance substantially equal to the height of a mold 24. This table has an opening 25 therein directly under the opening 16 and mounted within the opening 25 is a slide 26 having ber 29 having spaced openings 30 in each of which is mounted a slidable block 31. Each block is connected by a pitman 32 to a crank 33 carried by a shaft 34. This shaft has a series of cranks which are out of alinement with each other and each crank is connected to one of the blocks 3l. Vithin each block is slidably mounted a head 35 having a stem 36 the lower end of which has any suitable means, such as a nut 37, for limiting the upward movement of the head relative to the block. A spring 38 is mounted on the stem and within each yieldable support for the head 35.

A propelling rod 39 extends above the loosely clutch table 23 and has that end thereof above the table preferably mounted on anti-friction rollers 40 or the like, while the other end of the rod is preferably provided with an anti-friction roller 41. A weighted cord 42 is attached to the rod 39 and is mounted on a guide sheave 43 or the like, this cord serving to hold the rod 39 normally retracted away from the mold on the table 23.

A longitudinal shaft 44 is journaled within the structure 1 and is provided, at one end, with a crank arm 45 the Wrist pin 46 of which is journaled in a block 47 mounted in a slot 48 extending longitudinally within a pitman 49. One end of this pitman is pivotally connected to the beam 20. Notches 50 are provided in the sides of the slot 48 and any of these notches are `designed to receive a receiving plate 51 which,

when in position, serves to limit the movement of the block 47 within the slot 48. When the parts are arranged as in Fig. 2,

block 47 is held against sliding movement in the slot. Obviously, however, by shifting the plate 51 into some of the other notches in the walls of the slot, block 47 is capable of a limited sliding movement, thus reducing the movement of beam 20 duringthe rotation of the crank arm 45.

A large driven gear 52 is secured to one end portion of the shaft 44 and carries, upon one face, two cams 53 and 54 respectively. Cam 53 is designed to move against the roller 9, while cam 54 is adapted to move against the roller 41. Gear 52 meshes with and receives motion from a smaller gear 55 which is secured to a drive shaft 56 which may be operated in any suitable manner, as by means of a belt, not Ashown, mounted on a pulley 57. A gear 58` is member 59. Another clutch member 60 is feathered on the shaft 56 and the two clutch members 59 and 60 are yieldingly pressed apart by a spring 61. An arm 62 extends from the clutch member 60 and into the path 'of a cam 63 on the gear52. Gear 58 constantly meshes with a gear 64 secured to a shaft 65. This shaft transmits motion through gears 66 and 67 to the shaft 34 hereinbefore referred to. y, In using the apparatus the compartment 13 of the hopper is partlyor entirely filled with the material of which the bricks are to beformed. A mold 24 is placed between the-plate 15 and slide 26 and an additional mold is placed between said mold 24 and the rod 39.

The parts are so timed that immediately following the placing of a mold 24 under the opening 16 by the shifting of rod 39 by cam 54, the tamping rod 17 will be elevated and as this tamping rod begins its upward movement, plunger 7 will be` projected inwardly, thus forcing under the tamping mounted on shaft 56 and hasV ai rod 17 that portion of the material lying in the path of the plunger 7. Immediately following or simultaneously with this action the cam 63 comes against arm 62 and thrusts the clutch member 60 into engagement with clutch member 59 so that gear 58 will thus be coupled with the rotating shaft 56. Consequently `motion will be transmitted to the crank shaft 34 and slides 31 will be rapidlyV reciprocated, causing the Ayieldingly supported heads 35 to` tap Vthe bottom of the slide 26, which tapping will be transmitted through the slide to the mold thereabove. Consequently the material discharged under the tamping rod by the plunger 7 will gravitate into the mold and the tapping of the mold will cause portions of the material to pack in all of the corners of the mold. The plunger 7 then retracts into the opening 6 and tamping rod 17 descends, pressing the material tightly into the mold. The tapping due to the rotation of the shaft 34 ceases as the tamping rod becomes edective and as soon as the material has been properly packed within the opening 16 and the mold 24 thereunder and said rod 17 begins its ascent, rod 39 will be thrust longitudinally by its cam 54, pushing a new mold into position under the plate 15 while the filled mold will be forced out of position. During the removal of the filled mold, the lower edges of the walls 'of the opening 6 will act as cutters and will scrape off the material from the top of the mold, leaving -the molded bricks smooth.

From the foregoing it will be apparent -that it becomes unnecessary to pack any of the material by hand and all of the large particles aswell as the smaller particles will be received in the mold andproperly packed without hammering the material by hand as heretofore.

Obviously instead of tapping the mold in the manner pointed out, the structure illustrated in Figs. 5 and 6 may be utilized. By referring to these figures itwill be noted that aslide 68 is arranged under the mold 69 and this slide, which may, be Vprovided with rollers 70, has springs 71 under it. Each spring is adapted to be engaged by spaced projections 72 formed on a wheel 73, all of the wheels being attached to a'shaft 74 corresponding with the shaft 34 heretofore referred to. Thus it will be seen that `when said shaft 74 is rotated theY projec- 71 and will cause the slide 68 to be rapidly vibrated, thevibrations being transmitted to the mold 69 with the result that the material dischargedinto the mold will be properly packed. l

, As shown in Fig. 1 the arm 62 can be eX- tended downwardly so that its lower end Will slide Within a guide slot 75 so as thus to be held against rotation with the shaft 56.

Guide brackets 76 can be mounted on the frame of the machine for supporting the rods 8 and 39.

lVhat is claimed is:

l. The combination with a mold support, means for feeding a charge of material into position above a supported mold, of means` for jolting the mold support during the feeding of the mold, and means for tamping the mold.

2. The combination with a mold support, and an apertured feed plate thereabove, of means for automatically feeding a charge of material onto said plate, means for automatically jolting the mold support to pack material by gravity Within the mold, and means for automatically tamping material through the feed plate and into the mold.

3. The combination with a mold support, of mechanism thereunder for intermittently tapping said support, means for successively directing a mold onto the supportI and 0E of said support, a feed plate above the path of the mold and having an aperture therein, means for directing charges of material onto the feed plate when a mold is in position thereunder, means for automatically operating the tapping mechanism during and subsequent to the feeding of the charge of material to the mold, and means for automatically tamping the material through the feed plate and into the mold.

4, rlhe combination with a mold support and tapping mechanism thereunder and cooperating therewith, of a drive shaft, a Wheel driven thereby, a bulk holder, separate means operated in timed relation by the Wheel for successively directing a charge of material from the bulk holder and into a mold, tamping the material in the mold, and ejeeting the mold, and means controlled by said Wheel for automatically coupling the tapping mechanism to and uncoupliing` it from the drive shaft to tap the supported mold While a charge is being fed into the mold.
