EXPANSION-BOLT.

SPECIFICATION forming part of Letters Patent No. 737,555., dated August 25, 1903.

l Application filed November 19, 1902. Serial No. 132,023. (No model.)

To all wwm/ t may concern:

Be it known that I, CHRISTIAN DoRN, a citizen of the United States, residing in Philadelphia, Pennsylvania, haveinvented certain Improvements in Expansion-Bolts, of which the following is a specification.

An expansion-bolt as that term is used in this specification means a bolt whereby any desired object can be secured to a wall or other surface by means of gripping devices contained in a recess formed in the wall and expanded against the sides of said recess by means of a wedge. Quite a number of devices of this character all having the same principle of operation have been devised and: patented and are now in use; and the object of my invention has been to simplify and cheapen the construction of such an expansion-bolt and to reduce the number of parts necessary toits proper operation.

In the accompanying drawings, Figure lis a vertical section of an expansion-bolt con structed in accordance with my invention. Fig. 2 is an external view of the parts of the same detached from each other. Fig. 3 is a transverse section on the line c a, Fig. 1. Fig. 4 is a transverse section on the line b b, Fig. l; and Fig. 5 is alongitudinal section of a special form of wedge-nut which I sometimes employ.

l represents part of a wall or other surface to which any desired object is to be attached by means of an expansion-bolt or a number of suchbolts,this objectin the present instance being aconvexed plate or washer 2. In the Wallis formed a recess 3 of the proper diameter and depth for the reception ofthe member of the expansionbolt,these members comprising inthe present instance the wedge-nut 4, the counter-Wedge 5, and the screw-bolt 6. In the present instance the opening 3 is of circular form, and the wedge-nut4 and counter- Wedge 5 are externally rounded to correspond with the shape of the opening; but in the event of the opening being of other crosssectional form the external shape of the Wedges can be correspondingly changed. The inclined faces of the wedge-nut 4 and'connter-Wedge 5 bear upon each other, and the said nut 4 and Wedge 5 bear externally upon opposite Walls of the opening. Thus,as shown in the drawings, the nut4 bears upon the bottom of the opening and the wedge 5 upon the top of the same. Both nut and wedge are ribbed externally, so as to bite into the Walls of the opening. The nut 4 has a threaded opening for the reception of the threaded portion of the bolt 6 and is preferably counterbored, as shown at 7, beyond said threaded opening, so as to be free from contact with said threaded portion of the bolt. The counter-wedge 5 has a projecting sleeve 8, and both wedge and sleeve are centrally bored for the reception of the bolt 6, this bore being slightly elongated, as shown in Fig. 4, in order to permit the Wedge 5 to slide up and down upon the nut 4, as it is compelled to do in the operation of the device. The outer end of the sleeve 8 bears against the inner face of the plate 2 or other object which is to be secured in position, and the head of the bolt 6 bears upon the outer face of said plate 2. When, therefore, the boltis turned in the proper direction, the wedge nut 4 will be drawn forward, and the eect of this action Will be to press the outer face of said Wedgenut firmly against one side of the opening 3 and the outer face of the counter-Wedge 5 firmly against the other side of said opening. Hence the bolt 6 and the object to be retained thereby will be rigidly held in place, there being a direct outward thrust upon both nut and wedge throughout the entire length of each of them, thus insuring their firm hold upon the Walls of the opening. The purpose of the outwardly extending sleeve S is to locate the wedge-nut4andcounter-wedge 5 so far inwardly from the face of the Wall that the latter will offer the proper .resistance to expansion and will not be cracked or otherwise injured by the force exllled.

In applying the device the nut 4 and counter-wedge 5 are iirst placed in the opening. The plate or other object 2 is then properly disposed upon the face of the wall, and the bolt 6 is passed through the opening in said plate and through the central bore of the wedge 5 and its sleeve 8 and is screwed into the threaded opening of the nut 4 until the same has been drawn up against the Wedge 5 and the desired expansion has been efeoted. The

Ico

opening in the plate 2 need only be large enough for the reception of the stem of the bolt. Hence the plate is not weakened, as it would be if the opening therein were large enough to permit the nut or Wedge to pass through the same.

By using the nut 4 as one -of the gripping elelnents of the device I reduce the number of parts employed and correspondingly cheapen and simplify the construction of the device.

When the Wedge-nut has to be made of lead or other soft metal, as is required in some cases, Iprefer to cast the same around a nut 4J* of iron or other hard metal, as shown in Fig. 5, so as to avoid the necessity of cutting a thread in the softmetal and at the same time obtain a stronger thread.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination in an expansion-bolt, of a Wedge-nut, and aV counter-Wedge, each constituting a gripping member of the device, and a bolt passing through said expansionwedge and adapted to a threaded opening in the wedge-nut, substantially as specified.

2. The combination in an eizpansion-bolt, of a Wedge-nut constituting one of the gripping members of the device and having a threaded opening and a counterbore adjacent thereto, a counter-wedge constituting the other gripping member of the device, and a bolt passing through said counter-Wedge and engaging with the threaded opening of the nut, substantially as specified.

3. The combination in an expansion-bolt, of a Wedge-nut and a counter-Wedge constituting the two gripping members of the device, said counter Wedge having an. out- Wardly-extending sleeve thereon, and a bolt passing through said counter-Wedge and its sleeve and. engaging with the threaded opening of the Wedge-nut, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two lsubscribing witnesses.

CHRISTIAN DORN.
