To all 'whom it may concern.'

Be it known that I, WILLIAM KESPOHL, a citizen of the United States, residing at Hannibal, in the county of Marion and State of Missouri, have invented certain new and useful Improvements in Brick- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends certain new and useful improvements in brick machines, and has for its primary object to provide a machine of' this character which will be provided with a feeding compartment with a plunger mounted therein for forcing material from said feeding compartment to the main compression chamber Within which the upper and lower coperating reci rocatng plungers are movably engaged an( through which is adapted to operate the plunger emed for forcing the bricks formed in the maln compression chambers to the auxiliary or secondary compression chambers to be further compressed before being delivered from the machine.

The invention has for another object to provide a brick machine of this character which will be constructed in such manner that the bricks may be formed in the main compression chambers and then forced into the auxiliary or secondary compression chambers while a second set of bricks are formed in the main compression chambers.

The invention has for a further object to provide a brick machine oi this character which will be of such construction and operation that a number of bricks may be foi-ined in the main compression chambers with one operation of the reciprocating piston withinthc 'feeding compartment.-

'lhe invention has for a still further object to provide brick machine of the above .stati-1l charmcter which will be ot extremely simple construi'ztion and operation and comparatively cheap to manufacture aswell as high] y' eilicient in use.

With the above und other objects in View as will bes-.omo more apparent as the description proceeds, the invention consists in certain novel features of construction, combination um! .-irr'nngelnent of parts, as will be hereinafter more fully described and.

claimed; n l

For a complete understanding of my mvention, reference is to be had to the following description and accompanying drawings, in wh' ich: Figure 1 is a fragmentary plan view of the brick machine constructed 1n accordance with my invention.

Fig. 2 is a longitudinal section throu h the com lete machine, taken substantialy on the p ane of line 2-2 of Fig.1.

Fig. 3 is a vertical tra verse sectionV on the plane of line 3-3 of ig. 2, lookin in the directionindicated-by the arrow, an

Fig. -l is a rear elevation of one section of the machine.

Referring more particularly to the drawings, in which similar reference characters designate corresponding parts throughout the several views, 1 designates the ho per ositioned, above and depending in the eed- Ing compartment or chamben2 which is s'upported in elevated posti'on'hy suitable legs 3, as will be readily understood by referring to the"drawings.` i

Reeiprocally mounted transversely in the feeding compartment or chamber 2 is the main plunger 4 formed on the inner end of a plunger rod 5 which reciprocates through the outer end of the feeding compartment or chamber 2, as shown at 6, and may be operated by any suitable mechanism, not shown.` 1

Projecting rearwardly from the `upper edge of the main plunger Il isa guard plate 7 which is adapted for movement beneath the hopper 1 during operation4 of the plunger 4 to prevent the material in the hopper 1 from working back of the plunger 4. r The plate 7 is clearly shown in Fig. 2 of the drawing. 4

At the opposite end of the feeding compartment or chamber 2 is a plum ity of main compression 4chambers 8 separated by the vertical Walls 9 and having low rear walls 10 opposite the heatino chamber or compartment 2-and against which the material from the feeding chamberor compartment 2 is forced *by ,theV plunger 4 to form the bricks l1 within said compression ctimbers Vi?, the bricks being formed between' the ends of the plunger 4, the walls 10 and the lower andy upper compression plungers 12 and ii3 in the compression chambers 8. It will lic understood that. the compression chambers 8 have no bottoni and tcp walls, but the bricks ll are formed upon the lower compression plungers12 and the upper compression plungers 1.3 are thrust downwardly upon the top of the blicke 11 by suitable mechanism, not shown.

Each lower plunger 12 has a transverse V aving its opposite ends slidably engaged in elongated guide slots 17 of the standard 18, positioned upon and depending from the opposite sides of the main compression chambers 8. It will 4be understood that when the material for forming the bricks 11 is forced into the main compresmon chambers 8, the lower compression plungers 12 are in their lowermost position at the bottom of the main compression chambers 8 and the clamp bars 16 rest upon the lower walls of the uide slots 17.

After the rick 11 has been formed in each compartment 8 by 'the main plunger 4 and the plungers 12 and 13, the bricks 11 are moved upwardly by suitable mechanism connected with the cross bars 16, it `bein understood that `during the operation o formin .the bricks 11, the plungers 13 are moved ownwardly, each plunger 13` being rovided on its upper face with a transverse Eracin bar 19 to which is secured the lower end o 'a plunger rod 20 having its up er.

6nd co Yected with acrossbar 21 which as its'j opp site ends slidably 'mounted inthe elongated vertical guide slots 22 formed in the upstandin e gu1debars'23 at the opposite sides of t e compression compartments 8. When the lower plungers 12 are moved upwardly with the bricks 11 upon the same, however, the '.plungers 13 are forced upwardly thereby moving the cross bari 21 upwardly in the "guide slots 22. When the lower plun rs 12 reach the upper-ends of the rear wels 10 of the compresson'chambers 8, the bricks 11 arein position to be moved by the auxiliary horizontally moving pistons 24: normally positioned at the forward end of the compression compartments 8 and secured to the plungei-.rods 25 which are reciprocally mounted in the supports 26 andare spaced above the compartment or chamber 2. The plungers 24 may then be moved against the bricks 11 to force the Same from upon the'plung'ers 12 to position vupon the lower plungers 27 in the auxiliary or secondary chambers 28, said plunger-s 27 forming the bottom of said auxiliary comression chambers 28. The bricks 11 are rther compressed in the auxiliary or secondary chambers 28 by means of the plungers 24, lower Vplunger-s 27 and the upper plungers 29 of the auxiliary or secondarycompressionehembers28, one end of the bricks 11- being forced against and pressed a inst the outer endV walls 30 of laid chamers 2,8. It will also be underfstood that the upper plunger-s 29 or tne secondary compression c ambers 28 are in their lowcrmost positions, as shown Vin Fig. 2, when the second compressing operation is I completed.

After the second compressing operation is completed, the lower compression plungers 27 of the .secondary or auxiliary compres# sion chambers 28 are moved upwardly by the operating mechanism, not shown com nected with the cross bars 31 slidably engaged in the elongated vertical guide slots 32 in the supports 33 depending from the secondary or auxiliary compression chambers 28, said cross bars 31 being secured to the lower end of the plunger rods 34 depending from the center of the transverse bracing and reinforcing bars 35 secured to the under face of the lower plungers 27. This also causes the bricks resting upon the lower plunger 27 to be forced upwardly with the upper plungers 29 engaged against the same:

and thereby move upwardl the upper cross bars 36 engaged in the e ongated vertical guide slots 37 in the upstanding guide bars 38, also secured to the sides of the secondary or auxiliary compression chambers 28, it being ,understood that the cross bars 36 are mounted upon the upper ends of the 1unger rods 39 which have their. lower en s secured to the transverse reinforcing and bracing bars 40 mounted upon the up er faces of the upper plungers 29. As t e upper plungers 29 are moved to their uppermost position, the apron 41 hinged to the upper edge of the rear ends 30 of the secondary or auxiliar outwar .ly to receive the finished 1 the lower compression plungers this time 'at the up er edges of the oompresf sion chambers 28. Vt will be understood that the shelf l1 may be hinged te the end walls 30 in any suitable manner, such-as shown at42;

I n order toassure the and smooth rear ends or the bricks 11, I have provided a cut-o` or trimming blade 43 which has its lower edge secured to a transverse bar 44 having vits opposite ends en aged in vertical elon ated slots 45 provi ed in the supporting? end of the feeding compartment or chamber 2 in order to gui e'the blade 43 in its vertical movement, any suitable means, not shown, being connected with the. transverse bar 44 for raising and lowering the blade 43, the upper edge of thc blade being engaged between the innerend of the bottom revision of straight of the feedingcompartinent or chamber 2 compression chambers 28 is swun 27 being at'4 egs 3 at the inner plungers to elevate the bricks 11.
