BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 507,648, dated October 31, 1893. Application filed October 6, 1892- Serial No- 447,990- (No model-7 To 00% whom it may concern.-

Be it known that I, GEORGE OARNELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Brick-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in brick machines, and more particularly to the striker or pusher which operates to remove the mold from beneath the plunger after the latter has performed its function and started on its return stroke.

The main object in view is to prevent injury to or breakage of the pusher or striker and its operating mechanism in case a stone or other obstacle in the mold should interfere with its being readily moved by the pusher or striker. When this occurs means is provided for permitting the full movement of the pitman without movement of the pusher or striker. A novel and efficient construction and arrangement of parts is provided for accomplishing this result.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in Which--- Figure 1 is a face view of myim proved machine. Fig. 2 is a view at right angles to Fig. 1, with parts broken away and portions in section.

Like letters of reference indicate like parts in both of the views.

Referring now to the details of the drawings by letter, A designates the framing of the machine and in which the operating parts are mounted and supported. It may be of any suitable form of construction, and in suitable boxes or bearings a near the upper portion thereof is journaled shaft B carrying the fast and loose pulleys B and B respectively of any approved construction.

as seen in Fig. 1, the said pulleys being omitted from Fig. 2. On this shaft is a small pinion O which meshes with a large pinion O on the shaft C journaled in suitable bearings or boxes 0 on the framing as shown in Fig. 1, and on this shaft near one end is abevel pinion D which meshes with the crown wheel D on the stirrer shaft D which is journaled in suitable bearings and is designed to-operate the stirrer (not shown) in the clay box or chamber'D which is provided with an outlet d for the passage of the clay to the mold as will be understood from reference to Fig. 2 where the end of the clay box is broken away. On the other end of this-shaft O is a pinion E which meshes with a larger pinion E on a shaft E journaled in suitable boxes or bearings b on the frame as seen in Fig. l and provided with the cranks b as also shown in said figure.

F is the plunger which may be of any well known construction moving in the box E" and carried by the rod F which is uided at its upperend in a suitable guide f on the front of the clay box and upon this rod is screw threaded a nutor collar f between which and a pin or projection f the yoke G is sleeved upon the plunger rod, the said yoke being connected at its ends with the cranks b of the shaft E by the rods or links G as shown whereby the required reciprocatory motion is imparted to the plunger by the revolution of the said shaft by the gears E and E actuated from the main power shaft by the gears O and O as will be readily understood from the drawings. The bed H upon which the mold box is designed to be supported is rendered vertically adjustable to meet the requirements in any suitable manner, as by the jacks H Rails H are also provided for the support and guidance or the pusher or striker as well as for the molds, as seen in both of the views. The molds H maybe of any suitable construction having a bottom as seen in Fig. 2 and supported upon the rails beneath the box F as shown.

I is a scraper bar arranged over the front rising from this scraper are the pins 1' which are arranged tohave their upper ends pressed upon by the arms J which are pivoted as at 7' and provided with adjustable weights j as seen in Fig. 1 and resting upon the upper ends of said pins. The end J of the portion over the scraper is hinged at one end in any suitable manner so as to be thrown open in case any necessity presents itself for access to the pins and upon this hinged part are suitable flanges or cleats 7' which serve to limit the outward movement of the scraper as seen in both of the views.

K is a lever pivoted at 7- to the part J"as at the center as shown in Fi 1 and to this lever between its ends is pivoted one end of a link K the other end of which is pivot-ally connected with the scraper so that the latter may be thrown upward when desired by a simple movement of the said lever as will be readily understood from Fig. 1.

The gear wheel E has aninwardly-extending flange e as seen in Fig. 2, which is provided with a curved slot e as is also shown in said figure.

L is a rod or link having one end adjustably held in this slot and its other end pivotally connected with an arm L which in turn is pivoted at its other end to the arm M held to one end of a rock shaft M journaled in suitable bearings near the base of the machine as shown. The rod L is made in two or more parts adjustably connected in any suitable manner as for instance by a turn buckle Z as shown so as to lengthen or shorten it when occasion may require. The arm M which extends in an inclined direction as seen in Fig. 2, has pivotally connected with its upper end as at Z a horizontal rod N which is provided with an adjustable weight n rendered adjustable on the arm in any suitable manner as for instance by a set screw n as seen in Fig. 2. The arm N has near its pivot a lug or extension I in which is affixed a pin 11*, and upon this extension or lug is pivoted as at m a latch m having a hook m as seen in Fig. 2, the lower end of the latch being designed to normally impinge against the upper end of the arm L' as seen in Fig. 2, and the hook engaging the pin a as seen in Fig. 2.

On the rock shaft 31' are two or more arms which have connected thereto at their upper ends the curved arms 0 which are attached to the carriageP provided with wheels 0 and running upon suitable guides or tracks as seen in Fig. 2. This carriage carries the pusher or striker or mold-ejector Q, which is designed to travel in a horizontal plane and to eject the molds after the clay has been compressed therein by the filler-plunger.

. In operation, the parts are so timed that the molds haviugbeen placed in position the filler-plunger descends and presses the clay therein, and as the gear wheel E continues its revolution the arm M is moved in the direction of the curved dotted line in Fig.2 and the pusher or striker moved forward to eject the mold; if no obstruction is met the parts continue on their course without interference, the arm M, arm L, arm N, rod L and latch being held in theposition in which they are shown in Fig. 2, but should there be a stone or hard lump in the mold or filler box and so situated as to prevent the mold being ejected, the latch will be disengaged from its pin 01 which will leave the armN free to drop by reason of its weight and thus the free end of the latch will be withdrawn from its ongagement from the arm L when the latter with the rodL can continue their movements without actuating the pusher or striker as will be readily understood. The stone or obstacle can be removed by swinging the part J on its hinge and then the machine can resume its movements.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

hat I claim as new is 1. In a brick machine, mold-ejecting mechanism combined with a weighted arm with a pivoted latch, and a supplemental arm and a pin for engaging said latch constructed to render the mold-ejecting mechanism automatically inoperative to prevent injury thereto it an obstruction be met in the mold, substantially as described.

2. In a brick machine, mold-ejecting mechanism combined with an arm with a pivoted latch and a supplemental arm having means for engaging the latch and constructed to be automatically disconnected it the ejecting mechanism meet with an obstruction in the mold, substantially as specified.

In a brick machine, the combination with the mold-ejector, and the rock shaft with connections thereto, of the arm on the rock shaft, the arm pivoted thereon, the horizontal weighted arm pivoted on the firstmentioned arm, the latch pivoted on the weighted arm with one end engaging the second arm, and a pin on the weighted arm for engaging the other end of said latch, as and for the purpose specified.

4. In a brick machine, the combination with the mold-ejector and its actuating mechanism, of a weighted arm carrying a pivoted latch for normally holding the ejector and its operating devices in position to move simultaneously but permitting disengagement by the presence ofan obstruction, as set forth.

5. In a brick machine, the combination with the filler-box, of a scraper having vertical pins working loosely in vertical openings, the weighted arms independent of and bear iug upon said pins, the hinged part having vertical guides for the scraper, and the lever pivoted on said hinged part and connected with the scraper, as set forth.

6. In a brick machine, the combination with the mold-ejector, and its actuating mech- In testimony whereof I affix my signature in presence of two witnesses.
