Aug. 5, 1952 E HOLLOPETER ANCHOR DEVICE FOR CONSTRUCTION BLOCKS Filed July 28, 1950 2s 2| as NVENTOR EVERETT HOLLOPETER ATT RNEY Patented Aug. 5, 1952 dClair'hs.
This inventionpertains to an anchor forbu'ild ing blocks; and-'more fparticularlyfito ananchor having a pair-"oi? oppositelydisposedf pivotallymounted arms which are-mounted'in anelongated channel having novel means for-urging said arms toward-a fully extended position fcinseourihgfastud bolt in a hollow buildingconstructioniblock. Heretofore, expansion bolts-and anchorage-de vices have I been employed for -the=purpose of} an choring securing bolts desired positions; but
' various undesirable operational? features' wera frequently inherent" th'erein The present invention cont device for building blocks which will be simple-in construction, easily operated'i eificient in operation, and'low cost to ma'mrfactu-r'e.

Atfurther object .of the invention is -to"-provide an: anchoring device" for I1 construction block's wherein a channelized base having pivotal-1137* mounted gripping arms-as means for automatic centralization" 'of' thedevice a'sth'elateral grip ping arms are urged -into their final position.
A further object of the invention is to provide a novel channeliz'edi anchorsfon building blocks wherein spring actuated grippingv arms tend to centralize the device by permitting lateral movement of a channelized member onethesecuring Further; and other objeotsaofzthe inventionzmay be and'may :become apparent .fl'om a perusali of thepresent disclosure,.-and. it'is;tabe understood that various; changes and. modifications may'be The gripping arms 2-l 'have'shoulders-E2 8 formed on the inner-edges thereof and are-adapted to fit into the slots Z5 so 'th'atwhen thelocking fingers 26 are bentj upwardly to hold the gripping arms 21in proper positibn,- the gripping arms maybe freely 'movabletherein! Tension spring fl is 'used'}toretain-each of the gripping arms their" -nor'mally operative posttion as shown," urged-downwardly; iii-Fig! 2 There is a slot 30 formed in eaehof the gripping arms, which slot is=longer in dimension than the :headl3'l 'ofzthe ensieri spring il, to permittheisprin'g head be inserted therethrough. A
neck 32?. of the spring has aj smaller dimension thanlthexwi'dth of the slot iiw to permit free oper ationiof tlfe gripping arms without-binding of the neck'i 2 against ath'e sides of the slot- 3%. I

In the drawings: I Fig. 1 is a perspective View partially broken away showing the invention in its normal inoperative position.
Fig. 2 is a side view of the invention in its normal inoperative position, with the gripping arms shown dotted in its operative position.
Fig. 3 is a top view of the invention, partially broken away, in its normally inoperative position, showing the bolt in cross section.

It will be noted that the width of the foot is slightly less in dimension than the width between the sides of the inner surfaces thereof. This is desirable since the spring foot may have a length along the edge 3-1v sufiicient to permit a slight lateral movement only, of the spring during period of time before and while the anchoring device is being inserted and manipulated through its final gripping operation in conjunction with the construction block.
locking the shoulders 28 within slots 25 without appreciable likelihood of the locking fingers 26 binding on the base. 7 I
An elongated slot 36 is of sufficient width to permit free movement of the stud bolt 31 to move laterally within the slot without frictional en-1.. gagement between the stud 31 and the sides of the. slot 36. The length of the slot 36 is sufiicient to' permit a wide latitude of movement between the stud 31 and the slot of the channel'lflliso that there will be automatic centralization. of the channel on the stud as the device is placed in po sition and is in process of being tightenedi" f j i Fig. 2 shows the side wall 38, dotted, of a construction block, with the gripping arms 21,-shown dotted, as the serrated edges 39 or teeth bite into the sides of the constructionblock; g
In operation, members of Wood 40 will have holes drilled therein to receive the studs 31. After the studs are inserted through the holes in the wood 40, the threaded portion of the studs 31 are threadedly connected'tothe secured nut 4l which fits between the sides 23, and'may loosely engage the bottom 22, when in inoperative position, but which definitely engages the underneath surface of the flanges 2| when the-stud bolt3l is tightened.
of the construction block the anchor will slide downwardly within the hollow of the construc tion block while the teeth 33 ride onthe construction block side walls; w H
After tension is placed on thestlld 3Tto urge the anchor outwardly, the serrated edges of the:
matic centralization of the anchor device in relation to the stud. we It is pointed outthatl the lower end of the stud- 31 will always emergebelow. the bottom portion 22 of the anchor so thatthe length of the sl t 6. y a ement with the stud .31 will act as a limiting meansfor restrictinglth lateral movement of the nut 31 within the channel 20.:
