Description

To al( whom it may concernaif Y i, j Bef it knownthatfl, .Gnocca Q. Bovey, of

Oincinnati,ia-the county ,of` Hamiltonzand y Y State of Ohio, have invented',Qrtainf lmprorvejments'` in Brick-Machines, ofA ng=is a'speciiication ywhich he follow- My improvements are fol-theA cl-asso brick-machines Which-contain a series of molds in the lperiphery, of acyliny,

The.` irst; ',partof my invention- `consists ing' for'mingfsuch-Jmolds vin;- a tire-or `bftfnd encir.. clin gfthe body; of; the fwh'eel, which tire, WhengI ever the molds becometoo-muchworn,by,usen

can 'bei removed -5 from thek :Wh'eel, i, and either repaired or replaced byafnew andwunwornq, tire. .i

The" se'cond part `-ofV my invention consists in the provision of drifts or passageswforgthe escape or removal of clay andimiprisonedair from the sides of the .plungers e The third part of my invention consists in theapplication to the sides of the plungers, Within said passages, of yielding sleeves or scrapers, for detaching and depositing in the said passages Whatever clay may be adhering to the sides of the plungers.

The fourth part of my invention consists in the provision of a pressure plate or gage, Whose ofiice is to remove the surplus clay from each successive mold, and to press the remaining portion compactly into the mold, so as to impart a smooth and hard nishto the brick.

Figure l is vertical section of' my machine in the plane of rotation of the mold-wheel. Fig. 2 is a side elevation of the-same. Fig. 3 is a transverse section of said machine With its attendant pnlverizer and conveyer. Fig. 4 is a horizontal section at the lineman', with the mold-Wheel in relief. Fig. 5 is an enlarged section of a mold-plunger and portion of the xed cam, taken in the plane ot' the mold- Wheels axis. Fig. 6 is a section (to the same scale Aas Fig. 5) of thesame parts in a plane of rotation; Fig. 7 is a section taken` at the line Y Y. Fig. 8 is a perspective view of the fixed cani which actuates the plungers. Fig. 9 is a transverse section of the crushing and pulverizing apparatus. Fig.10 is a horizontal section of said apparatus at the line Z Z. Fig. 11 shows by side elevation a portion of l the,

My mold-Wheel 'fclose a seri Vs of equidistantradial,apertui the `apertiirlefQB in: @l1 body 4portion' plunger face-plate F is'larger than th orbedrGnftwplaneet Way of escape for Whatever air or clay may Work past the face-plate, and which, if notremoved, would penetrate to theinterior of the Wheel and clog the parts.

The chamber H also affords room for the attachment to the portion A of a series of elastic metallic Scrapers, I, which, embracing the plunger-body, detach therefrom Whatever clay may have adhered thereto, so as to prevent it Working down farther into the Wheel, and, by diverting it into the chamber H, to enable its ready removal from time to time. 1n other respects, the above parts, and also the xed cam J, together with the rollers vg', are substantially the same as the corresponding parts in the brick-machine described in my aforesaid patent ot' October 20, 1868.

Instead, however, of an additional moldwheel, I impart' the proper pressure tothe clay in each mold by means of a plate, K, firmly secured to an adjustable block, L, by bolts M, and the whole secured to the frame by bolts N. The Working-face of the plate K is concavely cylindrical to tit and hug the perphery of the tire C. Strips O, introduced between the block L and the frame, enable, by their removal or insertion, the adjustment of the pressure-plate K toward or from the tire, and thus enable the perfect contact of .partcula-s tra `diesalted f'iniiily naar yof ',October20, A1,868, h'utQd-ifer's from saidWileel4 in?. @para consists gftwocpoptiousm'amly, anji mumportion, A,Who`se rim a is'piercedwith` e "B, andl"""` iesof raf these important parts to be maintained even after they have become reduced by wear.

The pressure-plate K serves to cut o' snperuous clay, and to press the remainderl compactly into the mold with a uniform density and tinish.

In order to thoroughly crush, temper, and eomminute not only the crude clay but any rocks or other refractory particles it may contain, I introduce the clay into a hopper having a pair of cast-iron cylinders, I' P', from which the clay escapes in the form of a sheet, which is caught and torn topieces by a pair of intermeshing spiked Wheels, Q Q', from which the now thoroughly comminuted clay is conducted by a conveyer, R or R', into the hopper S of the brick-machine, said hopper having a series of ribbed wallowers, T T', substantially similar to those described in my patent aforesaid.

The form of eonveyer shown at R consists of a rotating shaft, V, armed with spiral blades v, and revolving; axially Within a tube, W, which extends obliquelyupward from the crushing` and pulverizing apparatus P P' Q. Q to the hopper S. These spiral blades v serve, in conjunction with projections w, from the interior of the tube `W, to still further comminute the clay in the act of elevating the same to the hopper X is a scraper, and U is an oi-bearer similar to those described in my aforesaid patent.

While describing the preferred forms of my improvements, I reserve the right to vary the same in non-essential particulars. For example, the crushing and pulverizing apparatus may be placed directly over the hopper S, so as to dispense with a conveyer, or the clay may be discharged onto a platform and be thence shoveled into the hopper by an attendant.

The tire C may be secured to the body of the mold-wheel by bolts instead of by keys.

The chambers H may be formed in a moldwheel cast in one instead of two pieces, and such chambers may be used `in a horizontal mold-wheel.

I claim as my inventionl. The provision, in a brick-machine, of the removable tire C D to the mold-wheel, substantially as and for the purpose designated.

2. The provision, in a brick-machine, of the chambers H around the plungers, for the objects set forth.

3. The provision, within the chambers H, of the yielding Scrapers I, hugging the plungerbody, for the purpose set forth.

4. The adjustable concave pressure-plate or gage K, in combination With mold-Wheel A C, block L, bolts M and N, and strips O, as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
