SPECIFICATION forming part of Letters Patent No. 658,122, dated September 1s,'19oo.

Application filed Octtiber 9, 1399.

To all whom it may concern:

Be it known that I, GEORGE H. ROGERS, a citizen of the United States, and a resident of Birmingham, J eflerson county, State of Ala bama, have invented certain new and useful Improvements in Door-Stops; and I do doclare that the following is a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form also a part of this specification.

This invention relates to improvements in door-stops which are in shape of a bolt and may be used in two ways, of which the first is as a look, like any ordinary bolt, and the other is as a check to merely hold the door at any point between extreme positions when'it is desired, for instance, to hold the door partly open.

My invention consists of certain features and details of construction whereby a device is caused to operate in the manner indicated.

In the following specification, and particularly pointed outin the claims at theend thereof, is found a full description of my invention, together with its operation, parts and construction, which latteris also illustrated in the accompanying drawings, in -Which Figure 1 is a central vertical section of the device with its parts in their normal position.

Fig. 2 is a front view of the device, showing it used as a locking-bolt. of the detached device. Fig. 4 is a horizontal cross-section on line 5 5 of Fig. 1. Fig. 5 is a similar section taken on a line above the previous section. v

In general my device consists of a housing containing a bolt and means whereby this latter is operated. The housing consists of a channel-shaped front part 7, provided with lugs 8 for attachment, and the openpart of which is closed by a plate 9,.forming its back. This plate rests within a recess 11 and is held in place by screws 12, seated in internal projections 13 of the front part of the housing 7. If the device is used in connection with a door, it is secured to the lower part 14 thereof, as shown in Fig. 1. 15 is the bolt contained in this housing, which it fits in general in a manner to be capable of a Fig. 3 is a rear view open.

sliding movement, therein. It is held nor mally elevated by acoil-spring 16, occupying .a recess 17, contained in the bolt and obtained by removing part thereof between its ends. This spring bears-against the upper end of this-recess, while its lower end rests upon a seat 18,projectinginwardly from back 9. This projection is very readily obtained by cutting out a part of the back and bending the same inwardly, as shown, causingit to reach into recess 17. A socket 19 is provided when the device is to be used as a bolt to look a door and sunk into the floor in proper position so as to be capable of receiving the depressed bolt whenthe door is closed. depressing the bolt it is provided with an arm 21, projecting outwardly from it and reaching through a slot 22 in the front part of the housing. The outer end of this arm is provided with a rubber tip 23, so as to serve of ratchet-teeth 24, provided in an upward extension 25 of bolt 15 and which after this latter has been sufliciently depressed are adapted to be engaged bya pawl 27, properly located for such purposeand pivot-ally attached to the housing.This pawl is held in engagement with the rachet-teeth by means of a spring 28, bearingagaiust the heel thereof. When it is desired to raise the bolt for the purpose of disengaging it, the temporary connection between pawl 27 and teeth 24 is broken, whereupon spring 16, by expanding to its normal position, lifts bolt 15 from the point of its engagement. For so releasing the bolt from the engagement by the pawl this latter is provided with an outwardly-projecting arm 29, which is depressed for such purpose, being rendered accessible by projecting through a slot 26 in the housing. The manipulation of this device is thus rendered very convenient by reason of these two stooping down.

A essuz projecting arms 21 and 29, which may be operated by the foot, arm 29 requiring only a light touch, thus obviating the necessity of Internal projections 13 are fitted to receive extension 25 of the bolt between them and serve as a guide for it.

Instead of entering a socket 19 the engagement of the bolt may be by frictional contact and pressure merely, if it is desired, for in stance, to merely hold the door at any point between extreme positionsas, for instance,

when it is desired to hold the door partly open. For such purpose the lowerpart of bolt 15 is hollow and contains a short supplementary bolt 31,'with a spring 32 behind it and pressing it normally outwardly. It is held in place by the enlarged end of a stem 33. The operation and manipulation of the device when to be used in this manner is the same as heretofore described, bolt 15 being simply depressed by using arm 21. This movement carries or tends to carry supplementary bolt 31 against the floor, causing, as soon as this latter is touched, a compression of spring 32, the outward pressure of which causes bolt 31 to impinge against the floor with a pressure which is sutficient for the purpose. Release of the bolt is bad, the same as before, by operating arm 29. Excepting, however, the presence of any unevenness in the floor at the particular point where the bolt-end is to engage the same, bolt 31 will not move down at all, or at least very little, and the only movement which occurs is by bolt 15. It is its downward movement which efiects the requisite compression of spring 32 for the purpose of obtaining the outward pressure of the same. To obtain a better contact and to prevent injury at the point where such takes place, the outer end of bolt 31 carries a rubber foot.

Having described my invention, I claim as new- 1. In a door-stop adapted to operate as described, the combination of a housing consisting of the hollow front part 7, and a back plate 9 for closing the same, a bolt having an independent spring-pressed end fitted between the two in a manner to be capable of a sliding movement, a spring to hold it normally elevated and occupying a recess in this bolt, an internal seat for the lower end of this spring projecting from the housing into the recess which it occupies, means to detachably hold the bolt in its depressed position and means to release it therefrom.

2. In a door-stop adapted to operate as described, the combination of a housing consisting'of a hollow front part 7 having a recess 11, around its open part, a back plate 9 fitted into this recess, internal projections 13, to receive screws which pass through. the back plate to hold it in position, a bolt fitted to this housing and capable of a sliding movement therein, an extension having ratchet-teeth reaching upwardly therefrom and fitted between projections 13 which guide it, a spring-actuated pawl pivotally secured to the housing and adapted to engage these teeth when the bolt is depressed and to hold it in this position and means to operate the pawl for the purpose of releasing the bolt.

In testimony whereof I hereunto set my hand in presence of two witnesses.
