which the following is a specification.

This invention relates to building-block A' machines of the type employed for'moldino' ,ifo

concrete oryotlier artificial-stone blocks, an

has for its objects to produce a comparay. tively simple inexpensive device of this character in-which the walls of the molds will be `moved toopen osition andthe cores automatically with rawn from the molds, one

wherein the operating mechanism will be locked against movement at the completion of the mold opening and closing operations,

' and one wherein the parts may be readily adjusted to provide for the formation of blocks of varyingl sizes. l i

VVitht ese and other objects in view the invention comprises the novel features of construction and combination of `parts more f jfully hereinafter described.

bers 2 and which in the formation of the horizontal portions 3 are spaced relatively to present slots or guideways 6, runningthrough` the entire length of the horizontal portions of the members. The main frame also includes a lurality, preferably four, of longitudina ly-eXtending channel -iron members or bars 7, arranged in parallel relation and adjustably secured to the frame members 2 by means offastening members or bolts 8, ar-

ranged in the guideways 6 and entered through the longitudinal slots 9,v formed adjacent the ends of the bars 7, a pair of which are disposed in cooperative relation at the transverse center of the frame.

Resting on the frame mem-bers 2 and' 7 as albase is a'niold or box 10, divided into a pair of coni artments 11- by means of a central vertica partition .12, clamped at its lower edge between the central pair of bars 7 and comprising side walls 13, end walls 14, and bottom boards or paletteV 15, the latter being provided with perforations 16 for the accommodation of main cores 17 and with perforations 18 to receive auxiliary cores 19, while the end walls 14 are provided on their inner faces with end cores 20. v

The sides 13 are adjustably and pivotally sustained on the frame by means of strap-y hinges '21, pivoted at their normally lower ends in bearing members 22 in the form of clip-bolts engaged with the horizontal portions 3 and entered through the guideways 6 thereof, while the end walls 14 are correspondingly secured on the frame by hinges 21,A the bearing members 22 of'which are entered through the longitudinal slots 9 in the frame-bars 7 and for movement longitudinally ofthe latter for obtaining a relative adjustment of the end Walls toward and from each other, a similar adjustment'of the side walls 13 being obtainable owin to arrangement of the clips 22 .in the gui es 6.

Disposed for vertical movement beneath ytthe mold is a core-supporting frame comprising a pair of transversely-disposed pieces or bars 23, disposed, respectively, adjacent the frame members 2, anda 'plurality of longitudinally-extending pieces or bars 24, disposed in parallel relation and arranged in cooperative pairs, as shown, the bars 2.4 being 'connected in pairs by means of transverse IOS bolts 25 and fixed to the bars 23 by means of clip-bolts 26,y engaged with the latter bars and with the bolts 25, as seen morel cleai'lyiinu Fig. 9, it being apparent that tlie pairs iii"- bars 24? may be adjusted relatively toward and fromreacli other in a direction loiigitudbl nally of the bars 23 through the medium oif the clip-bolts '26.

Extended transversely ol' the frame at points vertically beneath the bars 23 and journaled in bearings 35 on tl'ie vertical portions Ltof the lframe members isa pair of relatively spaced operation-shafts 36, one ci which is provided at one endwitli an'operat-V ing-lever 37, these shattsbeing connected for uniform movement-by 'a` sprocket-chain I belt 3S, arranged on sprodlret-Wlieels 39, fixed on the ends ci the shafts, there being alsoliredonfeaoli of said shafts a Grandi-arm4 318", plvoted at its outer end in a it-shaped bearing member or clip 4Q, hiredv on and adjacent the normally lower end ora connecting rod or link il ,wliichin turn is pivoted at its upjier end to an arm or link 42, 'fixed on tlie a( jacent bar .23, it being ynoted that the rod 4i" normally 'projects slightly belovify the clip 4() for contact with one edge of tlie'erank-arm' 3 8', thus to lock the latter against movement in one direction, which will limit the upward movement of the core-traine, while the down- Ward movement. of the latter is limited owing 'to contact of tlie connecting-rod il With tlie other side oi the arm 3 8', as'seenin Fig.

[ln practice when the pai ts are adjusted as in Fig. 1 the side and end Walls of the mold will be maintained securely in active position and with the cores 1projected into the mold, thus adapting the device for the for# esi,

which is rammed 'Witli tamping--inaulg tl'i'e upper side of the block is troweled olsnio'otb and immediately after this the lcver'l lis swung toftliegpsition illustrated in Fig. v2,

thus rotating the shafts 3 6, which serve ti'irou h' the-medium'of their connections' with t e eore-frame-to draw the latter vertif' cally'dotvnward for withdrawn-ig the cores' fromtlie mold and at the same time sw'm ing tbe side and end VWalls 'by means of thelinks 29 to open position, whereupon, the palette 15 with the blocksin position t ereon may be readily removed to thedr.ying-"house. It

is to be observed that' owingy to theiclips 22 being movablein the-guides 6 and 9 and the varms' 27 and 31 attached for adjustment longit'udinally of the' bars 23and 24 these parts may be adjusted for 'aecommodating'side and' susceptible of 'adjustment transversely for' 91e.'L l

properly centering the cores to acQfnd'Witli molds of varying sizes, 1t being understood,

of course, that when the size' ofthe mold is ychanged a f alette or palettes of. corresponding size Wil be employed therein.

From the foregoing it is apparent that I produce a coinparativel simple inexpensive device which is admirably adapted for theattainment'ofthe ends in view and one wherein tbe parts are susceptible of all necessary adjustments for varying the size of the mold, it l icing understood that in attainingtliese ends.

minor ebangesin tlie details herein. setfortli may be resorted to `Without departing from the spirit of the invention.
