Abstract
Abstract A cartridge assembly for the securement of anchor bolts in bore holes. The assembly comprises a cartridge having one component of a self-setting mix in a thin plastic casing, a chamber secured to the cartridge and having a sidewall with plural openings, and mechanical perforating means interposed between the cartridge and chamber. The second component of the mix is located within the chamber. The perforating means is arranged to mechanically rupture the cartridge and cause its contents to be carried to the chamber so that the two components intermix thoroughly and extrude through the chamber sidewall openings into the bore hole.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
113 words
A device for securing a bolt in a bore hole, said device being adapted to be positioned in said hole and comprising first and second axially aligned chambers, said first chamber containing a first flowable component of a multicomponent self-setting mix, said device further comprising a second chamber having radially oriented discharge openings, said second chamber being provided with a second component of said mix, and rupturing means to induce flow of said first component into said second chamber whereby upon application of further inwardly directed axial force, said first and second components are urged radially of said second chamber through said discharge openings and outwardly of said second chamber toward said hole.
Claim 2
Independent Claim
113 words
A device for securing a bolt in a bore hole, said device being adapted to be positioned in said hole and comprising first and second axially aligned chambers, said first chamber containing a first flowable component of a multicomponent self-setting mix, said device further comprising a second chamber having radially oriented discharge openings, said second chamber being provided with a second component of said mix, and rupturing means to induce flow of said first component into said second chamber whereby upon application of further inwardly directed axial force, said first and second components are urged radially of said second chamber through said discharge openings and outwardly of said second chamber toward said hole.
Claim 3
Dependent Claim
27 words
The cartridge assembly of claim 1 wherein said means comprises a cap having at least one hole therein and plural pointed projections extending upward about said hole.
Claim 4
Dependent Claim
20 words
The device of claim 2 wherein said second chamber comprises a pair of concentrically spaced mesh sleeves forming said sidewall.
Claim 5
Dependent Claim
26 words
The device of claim 3 wherein said one component is disposed as a layer of paste on the interior of the innermost of the concentric sleeves.
Claim 6
Dependent Claim
12 words
The device of claim 4 wherein said connection means comprises a collar.
Claim 7
Dependent Claim
14 words
The device of claim 5 wherein said collar is formed of a plastic sleeve.
Claim 8
Dependent Claim
31 words
The device of claim 1 wherein said second chamber comprises a tube having a circular sidewall and a bottom wall, said sidewall including said plural opening immediately adjacent said bottom wall.
Claim 9
Dependent Claim
28 words
The device of claim 7 wherein said mechanical perforating means comprises a cap having at least one hole therein and plural pointed projections extending upward about said hole.
Claim 10
Dependent Claim
24 words
The device of claim 5 wherein said tube includes a mass of woven mesh material having openings, to create turbulent flow within said chamber.
Claim 11
Dependent Claim
24 words
The device of claim 9 wherein said one component comprises a mass of paste located under said cap and above said mass of strands.
Claim 12
Independent Claim
164 words
A method of anchoring a bolt into a surface, comprising drilling a bore hole of adequate diameter and depth into said surface, inserting into said bore hole a device comprising first and second axially aligned chambers, said first chamber containing a first flowable component of a multicomponent self-setting mix, said device further comprising a second chamber having radially oriented discharge openings, said second chamber containing a second component of said self-setting mix, and rupturing means to induce flow of said first component into said second chamber, introducing the bolt to be anchored to contact said device and by a ramming action to take the device to the back of the hole and cause the device to be ruptured and subsequent collapse of the device whereby as said ramming action proceeds, said first flowable component is caused to flow into second chamber and then to be discharged radially of said second chamber through said discharge openings and outwardly of said second chamber toward said hole.
