- This invention relates to improvements in post anchorage, with particular reference to improved means for connecting posts and similar frame members to anchors which have been previously embedded in concrete with their upper ends exposed for connection of a post or other frame member thereto.
- the primary object of the invention is to provide an improved post anchor with associated means to facilitate the connection of a post therewith.
- Ancillary objects are to provide an anchor which is adapted to receive, interchangeably, any one of a set of metallic caps suited to the requirements of the particular installation, whereby one or more than one post may be connected to a single anchorage, or whereby one post and an associated relatively movable frame member may be so connected. Also to provide means whereby the post and cap plate may be securely clamped to the embedded anchor, and whereby the operation of assembling the cap plate and the post with the anchor may be expedited and a subsei quent separation of the parts facilitated.
- Figure 1 is an elevation, partly in vertical section, of an improved post anchorage embodying my invention, the upper portion of the post being broken away.
- Figure 2 is a View of the same, seen at right angles to Figure 1.
- Figures 3 and 4 are plan views of cap plates.
- the embedded portion of the improved post anchorage comprises a base member 10, from one portion of which arms 11, preferably upwardly divergent, extend and connect the base with a generally rectangular top block 13 having therein a rectangular cavity 14 partially overhung by a top wall or flange 15 and spaced side flanges 16, un-
- This provides an anchor member having a base portion 10 which extends laterally from the arms 11 to securely hold it in position and prevent it from being withdrawn from the concrete in which it is embedded. Also, it will be observed that the concrete, while still plastic, will flow or be pressed into the space between the arms 11, thereby forming a continuous bond through this space and providing an anchorage of maximum strength and permanence in proportion to the weight of metal employed.
- a cap plate 22 may be applied to the top of the anchor, this cap plate having a hole 23 through which the bolt 18 may pass and also having de pending tapered lugs 24, 2i and 25.
- Lug 24 enters the cavity 1-1 for engagement with the inner face of the side wall 19.
- Lug 24 engages the outer face of the opposite wall and lugs 25 engage the outer face of the side walls, thereby preventing the cap plate from shifting on the anchor when clamped thereto and to the post, as hereinafter explained.
- the top of the cap plate is provided with a cylindrical socket 26, concentric with the bolt hole 23, and after this cap plate has been applied it may be clamped securely to the anchor by a nut 28, threaded upon the bolt 18 to clamping position.
- This nut 31 is formed integrally with a plunger shaped member 32, the upper end of which fits snugly within the post and is secured thereto by a cross rivet 33.
- the lower end of this member comprises the nut 31 and is connected with the upper or riveted portion 32 by side bars 34 which also snugly fit within the post 30, the lower end of the post being clamped to the cap plate 22 and the nut 31 being fitted within and riveted to the post at its upper end, a cantilever action is obtained which very efiectively resists lateral strains resulting from pressures upon the upper portions of the post, since any such pressure applied to one side of the post must tend to cause it to fulcrum at the other side upon the plate 22. A tilting movement upon this fulcrum will be resisted by the riveted portion 32 of the nut, the latter being held against tilting movement by the bolt 18.
- the post may therefore be secured to the anchor by adjusting it vertically over the bolt 18 and rotating the post about its own axis to thread the bolt into the nut 31 until the lower end of the post is securely clamped to the cap plate 22.
- the lug 2a is within the socket 14 of the base and the plate 22 may therefore be shifted in a direction to carry this lug slight- 1y away from the wall 19, if necessary, to ob tain registry of the bolt 18 with the nut 31.
- the base being rectangular, it is obvious that a rotary movement of the plate upon the base is not possible. Therefore, the plate 22 may be clamped to the anchor independently of the nut 28 although the latter will be found serviceable to hold the anchor plate 22 and bolt 18 in assembled relation when shipped or stored independently of the post.
- cap plates will be selected which have sockets 26 of a diameter stantially equal to that of the post to be received in such socket.
- the cap plate 22 is provided with a laterally projecting arm 36 having at its outer end an upwardly projecting trunnion 37 to which another post may be secured or upon which ahorizontally swinging arm such as the arm 38 shown in Figure 1 may be journaled.
- the anchor is associated with a stall frame, of which the post seems a part, the trunnion 37 may be employed as a pivot for supporting the arm 88 of an auxiliary post 40 to beswung into and out of proximity to the post or to an associated stanchion as shown in Letters Patent of the United States, 1,002,275 granted to V. D. James for improvements in Stanchion supporting frames.
- cap plate 22a may be employed in substitution for the cap plate 22 shown in Figures 1. and 3.
- the cap plate 2264 may be identical with the cap plate 22 with the exception that the arm 26 and trunnion 3'? are omitted.
- a great variety of cap plates may thus be employed to suit the requirements of any installation.
- the anchor will be embedded in the concrete of a floor or beam, leaving only its upper end exposed for the reception of the cap plate.
- the cap plate may be applied while the concrete is being poured and the anchor may be so disposed that the upper surface of the concrete will be substantially at the level of the upper surface of the cap plate as indicated by dotted lines in Figure 1. In that event, all but the upper surface of the cap plate being embedded, it will its-elf be anchored in the concrete, the lug 15 extending downwardly therein to any desired depth, dependent upon the vertical dimensions of this lug.
- the primary function of the cap plate is to cover the recess in the anchor after the bolt has been engaged therein. Secondary functions are to relieve the bolt from lateral strain and to facilitate the connection of frame members other than the post with which the bolt is directly engaged.

.4 a! OLSON POST ANCHORAGE Feb. 23, 1932.
Filed April 19, 1930 INVENTOR.
- ATTORNEYS Patented Feb. 23, 1932 UNITED STATES JOHN B. OLSON, OF FORT ATKINSON, WISCONSIN, ASSIGNOR TO JAMES MANUFACTUR- ING COMPANY, OF FORT ATKINSON, WISCONSIN, A CORPORATION OF WISCONSIN POST ANCHORAGE Application filed April 19,
This invention relates to improvements in post anchorage, with particular reference to improved means for connecting posts and similar frame members to anchors which have been previously embedded in concrete with their upper ends exposed for connection of a post or other frame member thereto.
The primary object of the invention is to provide an improved post anchor with associated means to facilitate the connection of a post therewith.
Ancillary objects are to provide an anchor which is adapted to receive, interchangeably, any one of a set of metallic caps suited to the requirements of the particular installation, whereby one or more than one post may be connected to a single anchorage, or whereby one post and an associated relatively movable frame member may be so connected. Also to provide means whereby the post and cap plate may be securely clamped to the embedded anchor, and whereby the operation of assembling the cap plate and the post with the anchor may be expedited and a subsei quent separation of the parts facilitated.
In the drawings:
Figure 1 is an elevation, partly in vertical section, of an improved post anchorage embodying my invention, the upper portion of the post being broken away.
Figure 2 is a View of the same, seen at right angles to Figure 1.
Figures 3 and 4 are plan views of cap plates.
Like parts are identified by the same reference characters throughout the several views.
The embedded portion of the improved post anchorage comprises a base member 10, from one portion of which arms 11, preferably upwardly divergent, extend and connect the base with a generally rectangular top block 13 having therein a rectangular cavity 14 partially overhung by a top wall or flange 15 and spaced side flanges 16, un-
* derneath which the head 17 of a bolt 18 may be engaged with the bolt passing between the flanges 16. The head of the bolt'may be manipulated into position underneath the flanges 15 and 16 by holding the bolt in an oblique position while the head thereof is 1930. Serial No. 445,634.
passing between the ends of the flanges 16 and the vertical wall19 of the cavity 14.
This provides an anchor member having a base portion 10 which extends laterally from the arms 11 to securely hold it in position and prevent it from being withdrawn from the concrete in which it is embedded. Also, it will be observed that the concrete, while still plastic, will flow or be pressed into the space between the arms 11, thereby forming a continuous bond through this space and providing an anchorage of maximum strength and permanence in proportion to the weight of metal employed.
After the bolt is in position, a cap plate 22 may be applied to the top of the anchor, this cap plate having a hole 23 through which the bolt 18 may pass and also having de pending tapered lugs 24, 2i and 25. Lug 24: enters the cavity 1-1 for engagement with the inner face of the side wall 19. Lug 24 engages the outer face of the opposite wall and lugs 25 engage the outer face of the side walls, thereby preventing the cap plate from shifting on the anchor when clamped thereto and to the post, as hereinafter explained.
The top of the cap plate is provided with a cylindrical socket 26, concentric with the bolt hole 23, and after this cap plate has been applied it may be clamped securely to the anchor by a nut 28, threaded upon the bolt 18 to clamping position.
A post 30, preferably cylindrical, is provided with an internal nut 31 into which the bolt 18 may be screwed. This nut 31 is formed integrally with a plunger shaped member 32, the upper end of which fits snugly within the post and is secured thereto by a cross rivet 33. The lower end of this member comprises the nut 31 and is connected with the upper or riveted portion 32 by side bars 34 which also snugly fit within the post 30, the lower end of the post being clamped to the cap plate 22 and the nut 31 being fitted within and riveted to the post at its upper end, a cantilever action is obtained which very efiectively resists lateral strains resulting from pressures upon the upper portions of the post, since any such pressure applied to one side of the post must tend to cause it to fulcrum at the other side upon the plate 22. A tilting movement upon this fulcrum will be resisted by the riveted portion 32 of the nut, the latter being held against tilting movement by the bolt 18. The post may therefore be secured to the anchor by adjusting it vertically over the bolt 18 and rotating the post about its own axis to thread the bolt into the nut 31 until the lower end of the post is securely clamped to the cap plate 22. The lug 2a is within the socket 14 of the base and the plate 22 may therefore be shifted in a direction to carry this lug slight- 1y away from the wall 19, if necessary, to ob tain registry of the bolt 18 with the nut 31. The base being rectangular, it is obvious that a rotary movement of the plate upon the base is not possible. Therefore, the plate 22 may be clamped to the anchor independently of the nut 28 although the latter will be found serviceable to hold the anchor plate 22 and bolt 18 in assembled relation when shipped or stored independently of the post.
By having the socket 26 equal in diameter to that of the post, blows or pressures against the post, tending to shift it laterally, will be resisted by the wall of the socket, thereby relieving the bolt from material strain. It will be understood that cap plates will be selected which have sockets 26 of a diameter stantially equal to that of the post to be received in such socket.
It is frequently desirable to attach auxiliary equipment to the same anchor which supports a post to be clamped thereto as above described. To facilitate this the cap plate 22 is provided with a laterally projecting arm 36 having at its outer end an upwardly projecting trunnion 37 to which another post may be secured or upon which ahorizontally swinging arm such as the arm 38 shown in Figure 1 may be journaled. here the anchor is associated with a stall frame, of which the post seems a part, the trunnion 37 may be employed as a pivot for supporting the arm 88 of an auxiliary post 40 to beswung into and out of proximity to the post or to an associated stanchion as shown in Letters Patent of the United States, 1,002,275 granted to V. D. James for improvements in Stanchion supporting frames.
If no equipment other than the post 30 is to. be secured to the embedded anchor, the cap plate 22a may be employed in substitution for the cap plate 22 shown in Figures 1. and 3. The cap plate 2264 may be identical with the cap plate 22 with the exception that the arm 26 and trunnion 3'? are omitted. A great variety of cap plates may thus be employed to suit the requirements of any installation.
Ordinarily, the anchor will be embedded in the concrete of a floor or beam, leaving only its upper end exposed for the reception of the cap plate. If desired, the cap plate may be applied while the concrete is being poured and the anchor may be so disposed that the upper surface of the concrete will be substantially at the level of the upper surface of the cap plate as indicated by dotted lines in Figure 1. In that event, all but the upper surface of the cap plate being embedded, it will its-elf be anchored in the concrete, the lug 15 extending downwardly therein to any desired depth, dependent upon the vertical dimensions of this lug.
The primary function of the cap plate is to cover the recess in the anchor after the bolt has been engaged therein. Secondary functions are to relieve the bolt from lateral strain and to facilitate the connection of frame members other than the post with which the bolt is directly engaged. If desired, the cap plate may form a part of the base of the post, although it is preferably separable in order to permit the interchange of cap plates of differing characteristics and also to permit shipment with minimum danger of damage, the cap plates being preferably assembled with the anchors, whereby the posts may be separately packed and shipped.
