' H. c. BLODGETT ADJUSTABLE BEARING FOR DOOR LOCKING BOLTS Filed July 12, 1941 V {Xi/"Jeff day y 49/04Zzff Patented Jan. 26, 1943 A o sir-so STATE-S? A J STA LE BEARING FOR noon LQCKING BOLTS Ares-"r OFFICE Herbert Cady Hartford City, 1nd,, as-. signor to OverheadDoor Corporation, Hartford City, Ind, a corporation of Indiana Application July 12, 1941, Serial No. 402,095

'5 Claims. (01. 292%1).

which is exceedingly simple and permits adjustments to be eifective as desired quicklyand commonly without the aid of tools.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined in the claims. A preferred embodiment of the invention is illustrated, in the accompanying drawing, in

which: a Fig. 1 is an inside elevational view of a vertically sliding door equipped with the adjustable bolt guide of my invention.

Fig. 2 is an enlarged fragmentary view partially in horizontal section illustrating the relation of the door, its track, the. bolt, and the adjustable guide member for the bolt.

Fig. 3 is a fragmentary front elevation of the guide structure and bolt associated therewith, the guide structure being shown partially broken away and partially in section. I

Fig. 4 is an enlarged fragmentary view partially in vertical section on line 44 of Fig. 1.

In the accompanying drawing, I represents a door casing or frame and 2 a vertically slidable door made up of sections 3-3 articulated or hinged together at 4. Tracks 5 are provided for the door guiding and supporting rollers 6. These tracks are supported by suitable brackets i. This association of parts is old in the art.

I provide a door locking means comprising a pair of rod-like bolts 8 pivotally connected at their inner ends to the actuating member 9 which is provided with a handle [0. It will be noted that the bolts are eccentrically pivoted to the actuating member. A key controlled locking means designated generally by the numeral II is commonly provided for securing the actuating member 9 in its actuated position.

The tracks are provided with slots I2 adapted to receive the bolts when they are in actuated position.

It is quite common experience for the floor or sill portion against which the door closes to change positions or of some part to settle which shifts the bolts relative to their keepers and the prevents engagement thereof. Commonly, a guide member" is provided such as is shown in the Johnson Patentv 1,983,856, issued December 11, 1934, this guide member being bolted to the door. To shift the same requires a mechanic or person of skill. I provide means whereby the outer end of the bolt may be quickly and easily adjusted to guide it to its keeper.

This means comprises a casing-like bracket or support l3 which is. fixedly securedtothe door by the bolts orlag screws. M. This support member is provided with. vertical slots IS. in its vertical side walls, these. slots being very substantially longer than the width of the bolt.

Within the support member I31 mount a vertically adjustable bolt guide or bearing member it, this member being supported by the bolt l1; arranged through the. slot, l8,in. the. front wall of the support member, the bolt. being provided with a thumb nut l9, so. that by loosening this thumb nut the guide member maybe. quickly adjusted to guide theouter end. of thebolt to. its keeper and the nut quickly tightened to clamp. the guidemember inits adjusted'position. This may be quickly accomplished; without the aid or. tools and by persons having little or no mechanical skill which is a very great factor as it is found to avoid many servicing trips otherwise required. It will be appreciated that such servicing trips are quite expensive, and the need of such servicing is of annoyance to all parties concerned inasmuch as the old structure frequently required the removal of the bolts and screw, and in replacing the same it was likely to leave the door more or less marred. My invention eliminates all of these objections. Further, it is of value not merely from the readjustment standpoint but from the initial installation as it pro-. vides for adjusting to meet varying conditions and may be adjusted by an unskilled Workman or person. 7

I have illustrated and described my improvements in a very practical commercial embodiment thereof. I have not attempted to illustrate or describe various adaptations that are possible as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described the invention what is claimed as new and desired to secure by Letters Patent is:

1. In a vertically sliding door structure including a door and a track therefor, the combination of a rod-like bolt, said track having a slot therein constituting a keeper for said bolt, a

rotatable bolt actuating member to which the inner end of said bolt is eccentrically pivoted, a guide for the outer end of said bolt comprising a. support housing mounted on said door adjacent said track and having a vertical slot in the side wall thereof through which said bolt is disposed and a vertical slot in its front wall, and a bearing member arranged within said support housing and adapted to slidably receive and support said bolt internally of said housing, said bearing member being provided with an element disposed through said slot in the front wall of said support housing and provided with a clamping nut engaging said element externally of the housing whereby the bearing member may be and supporting the outer end of said bolt and mounted on said bracket for vertical adjustment thereon to vertically adjust the path of movement of the bolt supported by said bearing member relative to said bracket, and means for effecting said vertical adjustment comprising a clamping element on said bearing member engaging in a slot in the bracket and a further clamping element engaging said first named element whereby the bearing member may be clamped in its vertically adjusted position on Y the bracket.

vertically adjusted to position the bolt relative to the keeper.

2. In a vertically sliding door structure including a door and a track therefor, the combination of a rod-like bolt, said track having a keeper for said bolt, a bolt actuating member by which the inner end of said bolt is swingably supported, a combined support and guide for the outer end of said bolt comprising a support housing mounted on said door adjacent said track and having a vertical slot substantially longer than thewidth of .the bolt and through which said bolt, is disposed and asecond vertical slot, and a bearingmemberadapted to slidably receive and support said bolt internally of said housing, said bearing member being provided with an element disposed through said second slot in said support housing and provided with a clamping nut engaging said element externally of the housing whereby the bearing member may be vertically adjusted to position the bolt relative to said keeper. V

3. In a vertically sliding door structure including a door and a track therefor, the combination of a lockingbolt, said track being provided with a keeper for said bolt, bolt actuating means operatively associated with the inner end of said bolt, and guide means for the outer end of said bolt comprising a bracket carried by the door, a bearing member slidably receiving,

4. In a vertically sliding door structure including a door and a track therefor, the com- I bination of a locking bolt, said track being provided with a keeper for said bolt, bolt actuating means operatively associated with the inner end of said bolt, and guide means for the outer end of said bolt comprising a bracket carried by the door and a bearing member slidably receiving and supportingthe outer end of said bolt and mounted on said bracket for vertical adjustment thereonto vertically adjust the path of movement of the bolt supported by said bearing member relative to said bracket, and means for securing said bearing member in its vertically adjusted position on said bracket without the aid of tools.

5. In a vertically sliding door structure including a door and a track therefor, the combination of a locking bolt, said track being provided with a keeper for said bolt, bolt actuating means operatively associated with the inner end of said bolt, a bracket carried by the door, and

a bearing member slidably receiving and sup-,

porting the outer end of said bolt and mounted on said bracket for vertical adjustment thereon to vertically adjust the path of movement of the bolt supported by said bearing member relative to said bracket, and means for securing, said bearing member in its vertically adjusted position on said bracket comprising a clamping bolt and a coacting nut.
