ALBERT BUJEWSKI, OF NASHVILLE, ILLINOIS.

GATE-CLOSER.

Application filed May 13, 1915.

To all whom it may concern Be it known that I, ALBERT BUJEWSKI, a citizen of the United States, residing at Nashville, in the county of WVashington and State of Illinois, have invented a new and useful Gate-Closer, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed in connection with a flexible element and weight, for moving a gate to a closed position.

The invention aims to improve the construction of the casing through which the intermediate portion of the flexible element is trained, the construction being such that the constituent parts of the casing may be detached readily for the insertion and removal of the sheaves which guide the flexible element.

Another object of the present invention is to provide a casing which may be assembled in different ways with supporting posts of different forms.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what isclaimed, without departing from the spirit of the invention.

In the accompanying drawings: Figure 1 shows in front elevation, a gate wherewith the device forming the subject matter of this application has been assembled; Fig. 2 is a top plan of the casing through which the flexible element is trained; Fig. 8' is a bottom plan of the casing; Fig. 4 is a rear elevation of the casing; Fig. 5 is a vertical section taken approximately on the line 55 of Fig. 3; Fig. 6 is a horizontal section taken approximately on the line 66 of Fig. 5; Fig. 7 is an end elevation of the casingg'Fig. 8 is a sectional elevation showing the casing mounted on a post differing from the post delineated in Fig. 1.

2 denoting the supporting post, and the numeral 3 designating a gate which is hingedly mounted on the supporting post 2 and cooperates with the striking post 1 in a manner requiring no further description.

The gate 3 is swung to a closed position by means of a flexible element 39, attached as shown at 40 to the gate, a weight 41 being secured to the free depending end of the flexible element 39. The flexible element 39 is trained through a casing mounted on the supporting post 2 and this casing will now be described in detail. The casing preferably is fashioned from metal throughout and embodies a main plate denoted bythe numeral 4 and shown in clearest outline in Fig. 4. When the easing is applied to the outer face of the supporting post 2, the plate 4 bears directly against the supporting post and the plate, therefore, may be referred to as a back plate.

In its upper edge, as shown in Fig. 4, the back plate 4 is provided with spaced notches 5 defining between them an upstanding lug 6. The back plate 4 is tapered to form a reduced, depending neck 7 in the end of which is formed a notch 8 defining spaced lugs 9. In its lower edge and upon both sides of the depending neck 7, the back plate 4 is equipped with attaching ears 10. The back plate 4 is provided with a bearing opening 11. Upstanding from the back plate 4 and located laterally beyond the notches 5 are attaching ears 12. Projecting forwardly from the back plate 4 at right angles thereto and in vertical alinement with the attaching ears 12 are upper wings 14. Disposed parallel to the upper wings 14 are lower wings 15.

The front of the casing'comprises an auxiliary plate 16 having a bearing 33. The plate 16 is connected with a top 17 embodying a rearward extension 18 having a notch 19, upon opposite sides of which are formed lugs 20 provided with upstanding attaching elements 21. The plate 16 extends clownwardly to form a neck 22 like the neck 7 and connected with the neck and extended rearwardly therefrom is a bottom 23 terminated in a depending attaching ear 24. Projecting rearwardly from the lower edges of the plate 16 are bottom wings 25.

When the front plate 16 and parts caragainst lateral movement, as shown in Fig.

ried thereby are assembled with the main or hearing plate 4, the cooperation between the constituent elements of the parts above mentioned is as follows :-The lugs 20 which form a part of the front of the casing are received in the notches 5 of the back plate 4, the lug 6 on the back plate being received in the notch 19 in the top 17 of the front portion of the'casing. The rear end of the bottom 23 of the front of the casing at its point of union with the attaching ear 24 is received in the notch 8 of the back plate 4, between the lugs 9. The bottom wings 15 on the back plate are lined up with the bottom wings 25 of the front portion of the casing, as shown at Fig. 3. The upper wings 14 of the back plate 4 coact with the top 17 as shown in Fig. 2, upon opposite sides of the extension 18. It is to be noted that in the parts 14 and 17 upon the one hand and 25 and 15 upon the other hand, cooperating notches are formed, the same cooperat ing to constitute bearing openings 26. Owing to the manner in which the front and rear portions of the casing are interlocked 4 the openings 26 remain of a circular contour. Journaled for rotation in the hearing 33, and in the opening 11 of the back plate 4, is a shaft 27 having a shoulder 28 receiving one end of a hub 30 constituting a part of a main sheave 29. Surrounding a portion of the shaft 27 is a bushing 31' having a reduced end 32 received immediately in the opening 11 of the back plate and defining a shoulder 34 which coacts with the back plate. Secured to the bushing 31 is a sleeve 35 in which one end of the hub 30 of the main sheave 29 is rotatably received.

The invention comprises an auxiliary sheave 36 loose on an axle 37 for movement longitudinally thereof and to rotate thereon.

This axle 37 may be received in the openings 26 at the right hand end of the casing, referring to Fig. 3, or in the openings 26 at the left hand end of the casing, the axle and the sheave being mounted in the last specified openings, in Figs. 1, 2 and 3 of the drawing. The auxiliary sheave 36 is horizontally disposed, the main sheave 29 being vertically disposed. The back plate 4 and the front plate 16 of the casing may be provided with any desired number of additional openings 38 permitting the use of main sheaves 29 of different sizes or permitting a shifting of the position of the main sheave. V

The flexible element 39, it will now be understood, is trained across the horizontally disposed auxiliary sheave, is extended across the upper edge of the main sheave 29, and

is prolonged downwardly to receive the weight 41, it being obvious that the flexible element, traversing the sheaves under the action of the weight will tend to draw the gate 3 to a closed position, when the same has been opened.

hen thecasing above described is assembled with the outer face of a supporting post, such as the supporting post 2, secur ing elements are passed through the attaching members 24 and 21 of the front portion of the casing, and the back portion of the casing as well as the front portion thereof, will be secured to the post. The foregoing explanation presupposes that a solid post is. to be used. Under some circumstances, a tubular post may be employed, the flexible element 39 being extended downwardly through the interior. ofthe tubular post.

a tubular post denoted by the numeral 42 and including a face plate 43. When 1t 1s desired to assemble the casing shown in Figs. 2, 3 and '4 with such a post,.so that of the post 42 and into this opening, the

casing is thrust, the attaching elements 12, 21 and 24 overlapping the outer face of the element 43, as will be understoodfclearly from Fig. 8. It will now be understood that the back plate 4 cannot be held' to the element 43 by inserting securingelements into the ears 21 and 24 as before, but in order to secure the casing in position when the same is arrangedas above described, securing elements 44 are inserted through the attaching elements or ears 10 and 12 of the back plate 4. The casing isnow so assembled with the tubular post 43 that the flexible.element 39 may be led downwardly inside of the post. Since the front portion of the casing is detachable readily from the rear or back portion thereof, it will be understood that the various sheaves may be mounted in place inthe casing and be removed or be shifted therein.

Having thus described the invention, what is claimed is f 1.'In a device of the class described, a casing including a back having upper and lower forwardly extended wings; a front In Fig. 8 of the drawings, there is shown front and the back on the other hand con- I stituting bearings for the auxiliary sheave whereby the same may be mounted at either end of the casing.

2. In a device of the class described, a casing including a back having upper and lower outstanding wings; a front comprising a top including an extension lying between the upper wings and provided with support engaging means, lower wings cooperating with the lower wings of the back, and a bottom coacting with the back, the bottom being provided with support engaging means; a main sheave disposed parallel to the front and the back and journaled therein; and an auxiliary sheave disposed at right angles to the front and back, the top and the upper wings upon the one hand, and the lower wings of the front and the back on the other hand constituting bearings for the auxiliary sheave whereby the same may be mounted at either end of the casing.

3. In a device of the class described, a casing comprising a front, and a back abutting against the front, the front having attaching means whereby the back may be held against a support by the front, the back having attaching means whereby the front may be held against a support by the back when the casing is reversed; and a pair of angularly disposed sheaves journaled in the front and in the back.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
