to means for supporting them and maintaining the alignment thereof.

Further novelty of my invention lies in means for resiliently clamping a guide rail to a structural member whereby relative movement between the rail and the structural member is resistingly permitted and the alignment of the rail thereby maintained.
It is an object of my invention, therefore, to provide an improved support for elevator guiderails.

Fig. 9 is an elevational view, showing in further detail the structure of the clamping member shown in Fig. 8.
Figs. 10, 11 and views, respectively,
in elevation, of the structure 12 are enlarged perspective of three of the elements indevice shown in Figs. 7 8 and 9.
In Figs. 1, 2 and 3 is shown a method for providing a common supporting means, in accordance with the principles of my invention, for an elevator guide rail 11, disposed in one hatchway, and an elevator guide rail 12, disposed in an adjacent hatchway. A structural member 13, being of an I-beam, channel or other suitable cross-section and constituting a part of a building structure, is horizontally disposed be- 30 tween the vertically extending guide rails 11 and 12. The member 13 is of substantial rigidity and possesses the necessary strength for structural purposes. It will not, therefore, bend under forces exerted by changes in the length of guide rails attached thereto, as by changes in length due to temperature changes.
A fiat resilient structural member 15 of such thickness that it is somewhat flexible, is suitably supported at both ends, in spaced relation to the upper surface or flange of member 13, by means of suitable washers or spacers 1'7, and is secured to the member 13 by bolts provided with nuts as indicated.
The height of the spacers 17 is such as to permit a flexure or bending of the central unsupported-portion of the member 15, toward or away from the member 13.
A short channel member 19 is welded, or otherwise suitably secured, to the upper surface of the structural member 15 at the central portion thereof. The flanges of the channel member 19 are vertically disposed in parallel relation to the web of the member 13, and the width of the member 19 is such as to substantially bridge the distance between the flanges of the guide Suitable shims 20 may be interposed between the vertical portions of the member 19 and the guide rails, as indicated.
Means for adjustably clamping or securing Y21 and, bolts and nuts gage and firmly press against the flanges of the rails 11 and 12 and the shims 20.
It will thus be clear that, in the event of an increase in length of a guide rail caused by eX- pansion thereof occurring during an increase. in temperature, the member 15 will flex or 'bend a suflicient amount to maintain the vertical alignment of the rails, although the member 13 remains rigid. It will be further apparent that the member 15 tends to resist relative movement between the guide rail and the member 13, and thus maintains a firm attachment of the permitting relative movement therebetween.
Referring to the modification shown in Figs. .5, 6 and.7, the resilient flexible structural member 15 is disposed horizontally'and supported at the ends thereof on angle brackets24; which are suitably secured to the structural member 13 at the. neutral axis of the bolts 25 provided with nuts.
web thereof, by Suitable bolts 27 .andnuts therefor may also be employed to secure the ends of the member 15 to the brackets 24.
A short angle-barv 29 is suitably secured to the central portion of the member 15 niidwaybetween fthebrackets 24, as by welding, one face thereof..extendingparallel to the web of the member 13for cooperating withthe flange of a guide rail 12. A suitable shim 20 is interposed between the flange of the guide rail 12 and the face of the angle-bar 29, and suitable lugs, boltsand nuts corresponding to the lugs 22' and 23, respectively, are provided for securingithe'rail to the member 29.
The foregoing'methods of supporting guide rails effect a resilient attachmentof the guide rails to structural members, such as the structural member 13, whereby therailsand structural members "are relatively movable and whereby the alignment'of the rails is-maintained in the eventof an increase in length of the guide rails caused by an increase in temperature.
However, in the event of a settling of one side of a building resulting in ther structural ma. bers 13 assuming a'position atia slight angle to the horizontal, the change in the perpendicular relation between the guide railsand the structural member 13 would tend to loosen them.
Iflhave provided, as one of'the novel'features of my invention, a clamping device, shown in Fig. "4, which is capable of'maintaining 'a-firm attachment of a guide rail tea-structural memberregardless of whether ornot the building settles.
The clamping device may be'employed as a substitute for the clamping lugs-'21, ormay I be employed to clamp a guide rail directly to 13, without the interposition a'rigid structural member, such as the member of a flexible structural member corresponding to themembr 15.
Referring to Fig. 4, a guide-rail 30 is-clamped to a structural member 31,'with a suitable shim 32 I rigid or flexible, that i interposed therebetween,*by means-of a ing 33 ,anda bolt 34 provided'with'a nut 35; As above explained, the structural member 31 may be either member 13 or the member 15.
The lug 33, having a concave central portion 36, is provided,
wist the lugs 21 and s, it may correspond to the 37 for engaging the flange of the guide rail 30, and, at the opposite end, with a flat face 38 for engaging a flat bearing member 39. The bearing member 39 is of suitable material, such as babbitt or lead, and is stationarily supported, as by being fitted-into a slot in aflat member 40, which is interposed between the concave portion of the lug and the shim 32. The member 40 has a concave portion for cooperation with the convex portion of the lug to effect a firm seat for the latter.
, A hole extends through the lug 33 in the center of the concave portion 36 for the reception of the bolt 34. A washer 35 is provided for the nut 35 and it is suifiicentlyconvex, on one face thereof, to conform substantially to the concave central .portion of the lug 33. guide rails to the structural member 13 while against the bearing member 39. Thus the guide rail 30 is securely clamped to the structural member 31.
If relative movement between the guide rail 30 and the structural member 31 occurs, the force tending to raise the end 37 of the lug 33, causes the smooth face 38 to press more firmly on the bearing member 39. The bearing member 39, being of lead, babbitt or other similar material, is compressedwithin the elastic limit thereof and thus exerts a force-of reaction which is transmitted through the lug 33, acting as a lever fulcrumed at the concave seat in the member 40, to the flange of the guide rail 30 whereby a resilient force-is exertedto resist relative movement between the guide rail and the structural member 31.
Although only one clamping device is shown in Fig. 4, it should be understood that a similar device is employed for the oppositely extending flange of the guide rail.
Another modification of a clamping device is illustrated in Figs. 8 to 12. This modification is of such construction that the clamping member cannot turn or twist when relative movement between a guide rail and the supporting structural member occurs.
Referring to Fig. 9, the clamping device comprises a resilient clamping member of U-shape and preferably of steel or other suitable material, having one leg thereof adapted to be rigidly secured to a supporting member, and a longer leg for resiliently engaging the flange of a guide rail to resistingly permit movement of the rail. I prefer, in the present embodiment, to secure the spring clamp 45 in operative position by means,
short leg thereof, the two holes being coaxially disposed A sleeve or bushing 47 (shown in Fig. 10), the outer diameter of which is smaller than the diameter of the hole 45a and the inner diameter of which is'the same as the diameter of the small hole 451), is adapted to be inserted through the largehole 45a and against the inner face of the short leg of the member 45.
The length of thebushing 47 is such that when one end thereof engages the inner face of the short leg, the other end projects a slight amount beyond the outer face of the long leg. at one end thereof, with a ball-face Asshown'in Fig. 9, a bolt 48, having a collar or washer 49 adapted to bear against the projecting end of the bushing 47, is inserted through the bushing and cooperating holes in the short leg oi member 45, in the shim 46 and in the supporting structural member 50 and is provided with a suitable lock washer and nut 52 for securing the short leg of the member 45 to structural member 50.
The extending end of the long leg of the member 45 projects over the edge of the flange of a rail 53 and, when the nut 52 is tightened, exerts a resilient pressure upon the upper face of the flange of the rail to resistingly permit relative movement between the rail 53 and the structural member 50. It will be clear that when the nut 52 is tightened, the collar 49 on bolt 48 bears against the projecting end of bushing 4'7, and has no effect upon the resiliency of the clamping member 45.
Abearing member 54 (Figs. 9 and 12) of substantially channel shape, may be positioned around the edge of the flange of the rail 53- and beneath the end of the long leg of the member 45 for the purpose of reducing friction when the rail moves relatively to the structural member 50.
A pair of spaced integrally-formed, or punched, lugs 55 are provided on one face of the bearing member 54 for engaging opposite edges of the extending end of the long leg of member 45 to prevent relative movement between the bearing member 54 and the member 45.
When the rail 53 moves relatively to the structural member 50, which may be either rigid or flexible in character, the flange of the rail 53 slides in the bearing member 54 against the resisting force caused by the resiliently exerted pressure of the long leg of the spring member 45.
The collar 49, being disposed adjacent to the outer surface of the long leg of the member 45, serves as a limit to prevent the long leg from being sprung out of its normal position to a degree in excess of its elastic limit, and thus insures continued resiliency of the member.
Although only one clamping device is illustrat ed in Fig. 9, it should be understood that a similar clamping device may also be provided for securing the oppositely extending flange of the rail 53.
It should be understood, further, that the clamping device employing the spring member 45 enables a guide rail to be directly clamped to a rigid structural member of a building structure and thus the interposition of a flexible member, such as the member 15 in Figs. 1, 2 and 3, is unnecessary, although such lexible member may also be employed if desired.
It will thus be seen that my present invention comprises means for maintaining the alignment of elevator guide rails regardless of changes in the length thereof due to temperature changes, and regardless of a settling of the building structure in which the rails are disposed.
Furthermore, it will be seen that I have provided means for resiliently securing a guide rail to a rigid structural member to resistingly permit relative movement between a rail and the rigid structure whereby the alignment of the rail is maintained.
It will also be seen that I have provided a novel. clamping device for resiliently securing an elevator guide rail directly to a rigid member of a building structure to resistingly permit relative movement between the rail and the rigid member without a loosening of the clamping device.
In addition, it will be seen that I have provided a clamping device for resiliently securing an elevator guide rail directly to a rigid member included in a building structure to resistingly permit relativemovement between the rail and the rigid member without a turning or pivoting of the clamping device. 1
