DOOR-STOP.

SPECIFICATION forming part of Letters Patent No. 760,528, dated May 24, 1904.

Application filed September 15, 1903- Serial No. 173,240- (No model.) I

To all whom it may concern:

Be it known that I, CHARLES C. DAVIES, a citizen of the United States, residing in N ewport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in the Construction of Door- Stops; and I do declare the following to be a clear, full, and exact descri pti on thereof, attention being called to the accompanying draw,- ings, with the reference characters marked thereon, which form also a part of this specification. V

This invention relates to improvements in the construction of door-stops, which are devices provided for thepurpose of holding a door in a certain position. This position may be one in which the door is completely closed, occupying a position between the jambs of its opening, and in which case the device, in conjunction with a socket-hole or keeper, serves to lock the door. Another position may be one at any point to'which it may be swung when open, in which case the device serves to merely hold the door against such causes which tend to close the same unintentionally'as,for instance, drafts, unequal hanging, &c. In such case the device operates by spring-pressure,

a bolt being caused to impinge against the floor, it being held in contact therewith by the spring-pressure. Some of these devices serve for either purpose only, while others maybe used in this .double capacity. My device belongs to this latter class and may be used to either positively lock the door in its closed position or hold it by yielding spring-pressure in an open position.

The objects of my invention are to construct such a device in the most inexpensive manner possible without sacrificing durability and usefulness. These objects are attained by the selection of the material, by the manner of working the same, and by the particular arrangement of the parts which facilitates their quick and convenient assembling.

In the following specification, and particularly pointed out in the claims following, is found a full description of the invention, together with its manner of construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 shows one of my devices attached to the lower outer corner of adoor and in a position where, in conjunction with a socket or keeper, it looks such door in a positive manner. Fig. 2 shows the device inactive. Fig. 3 shows the device in a sectional side view, it being then used to'hold the door in an open position by springpressed contact of the device with the floor. Fig. 4 is a horizontal section of the device. Fig. 5 shows the blank out of which the front part of the bolt-housing is formed. Fig. 6 shows the back wall of the housing. Fig. 7 shows the front part of the bolt-housing in perspective view and r as the same is shaped out of the blank shown in Fig. 5.

The operatively-active part of the device is a bolt 10, provided on its lower end with a rubber tip or shoe 11 to increase the frictional contact with the floor when used in a manner as shown in Fig. '3 and to prevent scratching of such floor in case an attempt is made to move the door before raising the bolt. To provide these shoes, I use rubber tubing, which I cut in pieces of proper length and which are held in place by being shoved onto the reduced end 12 of the bolt and against a shoulder1-3, resulting from suchreduction. The outer diameter of this shoe is such as to prevent it from projecting beyond the diameter of the bolt, so that in case the device is used. in combination with a keeper 14:, as shown in Fig. 1, any lateral strain or bearing is not against the rubber, but'taken up by the metallic part of the bolt.- This latter is fitted into a housing 15,. the lower end of which is open, and it has a. tendency tomove out of this opening, imparted-"by a spring 16 acting against its" upperend This spring isalso confined in the same housing and held in place by the'closed .upper end 17 of such housing.

-Thebolt is provided for its manipulation with a'knob 18, carried at the outer end of shank 19, which projects through a slot 21 in the front part of the housing. This slot -is of such a length vertically, that the bolt from its highest inoperative position, as shown in Fig. 2, may move down sufficiently into a locking position within keeper 14;, as shown in Fig. 1, in which the door is positively locked. This 2 leaves the bolt of course free to occupy any intermediate position for purposes of having contact with the floor and, as shown in Fig. 3, allowing also sufiicient play to accommodate any irregularities in the surface of such floor. To hold the bolt in an inactive position against the positive action of the spring, it is necessary to lock it positively in its highest posi tion, as shown in Fig. 2. This is done by turning shank 19 of knob 18 into either one of two notches 22. By providing two of these,

notchesno mistake can be made in turning the bolt, nor is it required to ascertain first to which side the bolt should be turned. The boltmay be dead-locked by a similar manipulation when in its loIwestor positive locking position, as shown in Fig. 1, where again notches 23 are provided, they being also duplicated for the same reasons stated'above.

The housing is held in place on thedoor' by attaching-lugs, one, 2 1, at'thelupper end and two lateral ones, 25 25, near its'lower end. The:

housing is made out of sheet metal and formed to the shape shown in Fig, 7 out of the blank shown in'Fig 5. This blankis cut out in one piece, containing all the attaching-lugs and also the upper end necessary to close the llOLlSf ing to confine spring 16. Slot '21 witlrthe notches at both its ends is simultaneously produced. After the housing is formed to shape, as shown in Fig. 7 out of the blank, as shown in Fig. 5', bolt 10 and spring 16 may be readily dropped into position througlr'the at the timeopen rear part'of the housing. (See Fig. 7.) After this this open part is" closed by the rearwall 26, fitted so as to rest against the'edges of the housing. It is held in place by clenching-lugs, two of which, 27 27, are

' provided at theupper. end, which are bent over and turned down against the upper attaching-lug 24;, while below similar lugs 28 28 are used, two on each side, which in like manner engage the lower attaching-lugs'25.

In order to provide the necessary metal for these clenching-lugs this rear wall is made correspondingly longer and wider.

"It will be noted that this device satisfies all requirements, serving as a locking device to andno difficulty .lis encountered in having shank 19 to assume its proper position within slot 21. The bolt with its knob 18 and shank 19 may therefore be all cast in one piece.

The rubber shoe is provided in the cheapest possible manner, its material in proper shape being purchasable in the markets, and its attachment is equally simple.

The arrangement of the lugs might be reversed-that is to say, the attaching-lugs might be formed on the back part 26 and the clenching-lugs on the front part 15.

' The locking engagement of the shank within the lateral notches in slot 21 maybe intensified by undercutting these'notches, as shown Having described my invention, I claim s new- In a door-stop for the purpose described, the combination of a bolt-housing of sheet metal closed at its upperend and consisting of two' parts, a front part substantially semicircular and a flat back part, attaching-lugs on one of'these parts and clenching-lugs on the'other one, the two parts being held to each other by the clenching lugs engaging the attaching-lugs, all of said lugs, as well as the end of the housing being formed integrally with the parts mentioned, abolt fitted between tlieseconne'cted parts, an actuating-spring behind it and a knob to manipulate the bolt.

2. The blanks for a two-part, sheet-metal bolt-housing which latter'is to be closed at one end', there being a blank for the front part which contains integrally the part forming the end of the housing and a blank for the rear part of the housing, one of these blanks containing integrally the attaching-lugs for the housing while the other contains integrally clenching-lugs which serve finally to connect the two parts of the housing by engaging the attaching-lugs of the other part.

In testimony whereof I hereunto set my sig nature in the presence of two witnesses.

CHARLES C. DAVIES. Witnesses:

C. SPENGEL, HERMAN H. DUEHL.
