To all whom t may concern.'

Be it known that we, JAMES M. PHILLIPS and HENRY D. PHILLIPS, citizens of the United States, and residents of Stanford, in the county of vLincoln and State of Kentucky, havey invented certain new and useful Improvements in Concrete-Block-Making Machines, of which the following is a specification. y

This invention relates to concrete block. making machines and has for lits yobject the provision of a device which will thoroughly tainp the concrete block forming mixture into moving` moulds so that the finished product will be in such a state that the same V may be removed from the mouldsat a predetermined point in the travel of the mould carrier and be handled without injury to the green blocks. Y

Another object of the invention is the provision of a tainpiiig device which will tamp the green materials .into moving moulds without injury to said moulds, the tamping face of the device being corrugatediii a` manner to direct the `lines of force at an angle .and rearwardly of the vertical rather than in a direct vertical manner.

iiother object of the invention is the provision Vot a mould block having ai pivotally Vmounted base whereby the iinished product nfiayA be readily removed from the mould by tilting the base. l'

Astill fur her object of the invention is the provision of an adjustment for elevating the bases of the moulds for forming blocks of Vvarying heights.

y Another object ot the "invention, is the provision of a shearing` plate for the tops of the green blocks and which is pivotally connected to the tamping head and oscillated thereby. Y

i A still further object ,of the invention is o the provision ofga driving mechanism for the moulds which 'is simple, eiiicient and which will periodically feed the moulds beneath the taniping head.

This invention will be best understood from aconsideration of theA following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless itis to be understood that the invention is not confined to the disclosure, being susceptible of such vchanges and modifications which shall define no inaterial departure from the salient'` features of the invention as expressed inthel appended claims.

Referring more particularly to the drawings itkwill be seen that the frame'or'bed upon which the track and the moulds are supported is entirely of angle iron const-ruction and a sufficient ,number of irons( are employed for the purpose of providing a vibration incident machine.

to the operation of the -which are in turn connected by means of reinforcing bars 6. 4A plurality of trans- The frame consists of a plurality of kverti- `cal standards 1 and 1a whichare connectedl longitudinally by means of rside barsv 2 .and base bars3. At the extreme opposite ends of the frame are located pairsf of vertical standards 4 which are connected by pairs of angle irons y5 transversely of the frame and Vverse bars 7a connect a pair ofthe longif tudinal bars 2 together which' carry the track above the tamping mechanism for reinforcing the standards at this point. Bars 7 carrythe track` not only Vunder the tamping head'but those portionsof the track which Y are opposite the tamping head.

` The transverse bars 7 and 7 a are provided with spaced vertical slots 8, as shown 'more particularly in Figure; 14 i in which are .adapted tobe seated-a pair of spaced tracks 9 andy 10. The upper edges iofthe tracks 9 and 10 extend sufficiently above the flanges 11 between ythe slots 8 ofthe angle bars 7 and 7a to `support thev bases 12 ofthe moulds to permit a roller 13 whichdepends 1 from the bases 12 of the moulds to freely pass the upper edge of the flanges 11, while l the tracks 9 and 10. are` supported by thel notches 8 in the vertical flanges of the angle irons. The outerrtrack members 10 are carried to the` opposite ends o'f the machine and curved, as shown at 14, beyond the opvposite end of vthe block making machine and supported by brackets 1-5 at these points which are secured to thehorizontal angle irons 5. The inner track members 9 ter-l fminate short of theV ends sov that the bases of thexmoulds are carried entirely by the curved portions 14 of the ,outer tracks 10.

The portion of the tracks below the tamper 16 rests upon adjustable bolts 17 which are screwed-into the horizontal angle Virons 7a and locked in place by means of nuts 18.

The bolts-provide a means vfor elevating the portions of the tracks just below the tamper 16 when the tracks are suiiiciently worn from continued use of the device.V

'The mould boxes are connected fin 4an endless chain and driven around the tracks by a suitable mechanism which willv be presently describedv with the base pla-tesy 12 resting on the upperr edgesof the tracks 9 and 10 and engaged by the rollers 19 projecting laterally from the outer faces of said tracks.

The roller 13 depending yvertically ,froml the base plate l12 engages the inner faces `of the tracks 9 and 10 and cooperates with rma/refr 22 is received within the perforations of the linger 2O and the lug 21 and is'pro-` vided with a head 23 'engaged by Va sleeve 24 which, at its lower end, rests upon the upper face of the Vfinger 20. A sleeve 25 on the pin 22 below the lug y21 engages said lug and ismaintained in position ony the pin22 by means ofy a perforated "disc 26.

28 (Figure 11) and adapted to be received between the finger 2O and the lug 21 andv receives the' pin 22 whereby the opposite ends of the base plates 12 are pivotally connected together and Vform an endless chain. f

A pair of cleats 29 are rigidly secured to and a cotter pin '27. y TheV opposite end of each base plate perforated as shown atv the upper faces of each base plate and provided with a perforated projecting end 30 adapted to receive a bolt 31. Saidfbolt is adapted to pivotally connect the VU-shaped member 32 to the outer free` end 30 ofV each cleat.

, An arm 33 has return bent portion 34 Y.

adapted to engage thev under face ofthe base plates 12 when the mould is located iny 'f a tilted position. A bolt 35 passing through perforations in the bridging portion of the U-shaped member 32 and the perforation 36 of the arm 33fis adapted toklock said arm to the U-shaped member. A partition plate 37 'is secured in a vert-icalv position' at the forward end of each base plate 12. Each of the arms v33 are perforatedv asshown at 38 to receive a bolt 39 which is screwed into a cleat 40 secured to the pallet`41of the mould per se.

A sleeve 42 on the bolt 39Vis adapted to determine the space between the bottoms 41 Y,

of the moulds and the arms 33. The length of the sleeve 42 also determines the height of the blocks 43 formed in the moulds.

table 44 is located adjacent the point where the blocks 43 are removed from the moulds when the moulds are tiltedlaterally'from the bases 12.

4At each end `of the frame is placed a driving spider 45 and an idling spider 46. The spider 46 is mounted onv the upperend vof a vertical shaft 47 'j upon which the spider idly revolves while spider 45 is rigidly cong nected with the upper end of the driven Vshaft 48f The lower end of shaft 43 is connected with a worm gear 49 which .in turn meshes with 'a worm 50 on the end of. a drive shaft 51.` This shaft is extended towards the center of the machine and kis provided with a ,bevelled gear 52 meshing with a pinion 53. Pinion 53 is rigidly connected with a shaft 54 and a 'clutch mechanism 55 connects shaft 54 with the shaft 56 when a leverv 57 is operated to throw the clutch in position. The lever 57 shown more particularlyv in Figure 2, is vpivotally connected at 58 on a transverse bar 7b and yextendsforwardly or rearwardly A.and abovev the spider 46 where-it may beconveniently grasped by the operator for operatingthe clutch. i y

T heupper endofshaft56is provided with v a gear 58 meshing with a :pinion 59011 a driving Vshaft 60. The shaft 60 is mountedV 'Located betweenthe'spaeed'vertical standards`1a at one portion ofthe track and below the tamper 16 are a pair ofspaced-side walls 66 which are maintainediinposition by means of blocks 67. VBy placing narrower blocks between the side walls 66 and the vertical standards 1a wider building blocks may be produced inthemoulds when desired. f course, "the pallets of the moulds must be correspondingly enlarged-to i to be received by a passage inthe elevated j the other end of the bar 82 is provided with` meetthe changed condition. These side lwalls 66 extend very =nearly thelength of the machine and adjacent the moulds where the ftamping of the 'material within the moulds yis accomplished. A hopper 68 is located above'the moulds and at the rear of the tamper 16 is adapted to feed materials 69 into the moulds which is compressedlby the tamper head 16. Y

An eccentric 70 is mounted on the shaft above the side Walls 66 and is adapted end 71 ofthe tamper 16. The tamping of the flatportion 7 2 ofthe head of the tamper 16 has corrugated under face which is so constructed that the corrugations 73 form a short concave face while the portion 74 of the corrugation forms a longconcave face' and the two together combinato provide a transverse convex rib 75. Avribv76 isfformed integrally with the upper wall of the tamper head and extends from'the cylindrical portion 71 of the tamping head to the lower reduced end which has a straight Yportion 47. YThe lowerv end of the rib is provided with atransverse passage' through which is inserted a bolt 78to which areY connected the links y7 9. These links are supported-attheir upper'ends by means of a rod 8O secured inl bearings 81 on, the anglel iron bars A82. 'The angle iron bar 82 is pivotally connected at 83 on one ofthe vertical-standards 1ay `while an arcuate'shaped lslot 84 adapted to .receive a bolt 85 'mounted on the other angle iron bar la. A rod 86' is-secured to the angle bar 82 and-has itslower endl inserted through a angle Abar 87 connected to the standard 1a A Anut 88 on thefthreadedend of the rod 86 is .adapted to adjust the-movable lendof the angle=iron v82- for adjusting the vvertical .16.' vItmustfbe borne in mind Athat there 4height-ofthe lower freef'end ofthetamper y are two angle irons v82`located in `spaced relation with `a duplication ofthe-adjusting 'means for the'bars. v i Y.

` .Y The operation of my device 1s as follows:

YThe materials Which form the blocks are .placed in the hopper 68 andare fed by gravity intOthe mould boxes travelling beneath 'saidhoppen As shown more particularly in Figure 1 the materials are permitted to-be heaped abovethe Amouldboxes and are only restricted by a partition 120. The shaft 60 is :driven through either of the pulleys 63 or 64er by both if desired and shaft 56 is driv-y en injits turn from shaft 60`by meansof the gears 58 and 59. Operation ofthe clutch by the lever 57 causes rot-ation of the 1 gear 49,shaft 48 and driving spider 45;. i Said spider drives the endless train of mould Vboxes and fitsthem' slowly beneath the hop per and tamping head. Rotation of shaft causesv the tampinghead 16 to be Vrecip-V rocatedthrough the eccentric and the materials are packed into the'mould boxes in Va direction `Whichxis at an acute angle to the ypredetermined stroke;
