ings, or the like. Hitherto it has been the practice to employ sleeves of metal that is softer than the metal of the rods or bolts received in the bores of the sleeves. In some of the devices of the prior art sleeves, together withthe portions of the rods threading the same are placed within holes or recesses in the Walls or other elements from which the rods are to be projected, whereafter the sleeves are upset or crowded into the spaces between the rods and the surrounding parts of the walls rigidly to secure the rods in position. In other devices the sleeves have been expanded into holding relation with the wall-portions by means of tools distinct from the rods, the rods being screwed or inserted in position upon the withdrawal of the tools. Lead has been found to be the vmost suitable material out of which to form the anchoring sleeves but inasmuch as the lead is soft the sleeves are liable to become loose, owing to the inability to maintain the sleeves Iunder sufficient compression.

In accordance with my invention I incorporate harder substance with the soft metal of the sleeves, this harder substance being capable of being retained under suilicient compression to enable the sleeves permanently to perform their function. The harder material is desirably in the form of small bodies of iron 'which are distributed throughout the lead sleeves and which coact wlth each other and also with the lead to receive and retain that degree of compression Which is requisite to the maintenance of the firm anchorage of the rods.

The lead is a material which is not only initially plastic when it is compressed in adj usting its relation to the supportmg bolt or element, but which also 1s permanently plastic to enable it and the coarse partlcles within it jointly to continue to perform their holding function. I also claim these particles with or without the lead.

I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof and in which Figure 1 is a longitudinal sectional view of an anchoring sleeve made in accordance with the invention; Fig. 2 shows one style of bolt or rod which is anchored in place by means of the sleeve of -my invention; Fig. 3 shows another type of rod which may be anchored by the new sleeve; and Fig. 4 is a sectional view on line 4-4 of Fig. 3.

Like parts are indicated by similar char acters of reference throughout the different figures. Y

The anchoring sleeve 1 of my invention is desirably formedl of molded lead which is indicated at 2. Small pieces 3 of iron or other relatively hard material are molded in the lead to be included in one consistent mass therewith. These pieces 3 may be formed out of Waste material such as iron turnings, chips and stamping's. In accordance with the preferred method of making the sleeves the iron pieces are loosely and promiscuously located in a mold whereafter the lead is poured into the mold, though I do not wish to be limited to this method of forming the iron and lead in one consistent mass. The lead thus acts as a binder to hold the pieces of iron together, the lead furnishing to the massed pieces of iron the element of compressibility in' order that the mass of iron may be reshaped when the sleeve is to be upset or compressed to enable it to anchor the rod that it is to hold in place. In Fig. 2 the rod or supporting element 4 is in the form of a threaded bolt having a head 5 of conical shape. The bore of the anchoringsleeve is threaded by the bolt. The head end of the bolt and the anchoring sleeve 1 are together placed within a cylindrical, recess or opening 6 formed in a supporting wall portion 7 whereafter an upsetting sleeve 8 of hard metal such as iron is driven inwardly to crowd or upset the sleeve and effect such a redistribution' of the iron particles 4 as to crowd or roll these particles between the rod or bolt and the surrounding portion of the wall, these particles being collectively placed under such compression as to maintain the bolt and Wall in firm assembly and rolling to those positions where they may perform their function, although I do not limit myself to this rolling action. After the upset element 8 has been made to perform its function it may be withdrawn or allowed to remain in place, as desired. It will be observed that the iron particles are more crowded at the ends of the sleeve than at the middle of the sleeve whereby exudence of the lead to the rear of the bolt head is prevented, this exudence being a dii'liculty be sufficiently large to engage Iboth the sup-` port and supporting element at points in a line oblique to the supporting element and extending obliquely across the gap between 'some of the threads and the surrounding portion of the wall, thus serving as compression members in a truss formation, these larger portions of iron then operatingindependently of the lead and independently of their companions -in firmly gripping the wall and rod and holding them in fixed relation. This direct cooperation of the iron portions with the rod and the surrounding wall is not indispensable' to the iirm anchorage ofthe rod, since it is apparent that the iron portionsmay coperate with each other and also with the lead in effectively holding the rod and wall in fixed relation.

While I have herein shown and particularly described the preferred embodiment of my 4invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention but having thus described my invention I claim as new and desire to vsecure by Letters Patent the following 1. The combination with a supporting element; of an anchoring element for holding the supporting element and formed of soft permanently plastic material and small bodies of hard material molded in the Soft material; and a support having an opening receiving said supporting element and anchoring element and engaged Iby the anchoring element which is crowded between the support and the supporting element to bring the small anchoring elements into rin holding relation with said supporting element and the support.

2. The combination with a supporting element; of an anchoring element for holding the supporting element and formed of soft permanently plastic material and small bodies of hard material molded in the soft material and having the soft material interposed between the same; and a support having an opening receiving said supporting element and anchoring element and engaged by the anchoring element which is crowded between the support and the supporting element to bring the anchoring element into firm holding relation with said supporting element and the support.

3. The combination with a supporting element; of a support with a recess therein in which said supporting element is received; and an anchoring element within the recess and engaging said support and supporting element this anchoring element being in the form of a hollow `sleeve composed of soft metal with particles of hard metal embedded therein, said hard particles being collectively under compression, to maintain the support and supporting element in iirm assembly.

4. The combination with a supporting element; of a support with a recess therein in which said supporting` element is received; and an anchoring element within the recess and engaging said support and supporting element, this anchoring element being in the form of a mass of soft metal with particles of hard metal embedded therein, said hard particles being collectively under compression, to maintain the supporting element and support in irm assembly.

In witness whereof I hereunto subscribe my name this seventh day of October, A. D. 1915.
