SLIDING GATE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed March 27, 1916. Serial No.'87,065.

To all whom-it may concern:

Be it known that I, THOMAS J. BROWNE, a subject of the King of England, residing at Oldham, in the county of Halifax, in the Province of Nova Scotia andDominion of Canada, have invented certain new and useful Improvements in Sliding Gates, of which the following is a specification.

This invention has relation to certain new and useful improvements in gates and it contemplates, primarily, the provision of a novel form of gate and supporting means therefor, whereby the gate may be easily and quickly operated with but little exertion on the part of the operator and which consists of but a few simple parts whereby it not likely to get out of order.

A further object of my invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint of the user and the standpoint of the manufacturer; and which, it is believed, may be manufactured at a comparatively low cost.

Various other objects and advantages will become apparent during the continuance of the following description.

These objects are accomplished by such means as are shownin their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claim.

In the accompanying drawings wherein like characters designate like parts throughout the several views:

Figure 1 is a view in front elevation showing my invention, as in its preferred embodiment, the gate proper being in a partly extended position;

Fig. 2 is a view in section taken on line 22 of Fig. 1;

Fig, 3 is a view in section taken on line 3-3 of Fig. 1; and

Fig. 4 is a fragmentary view of the gate and gate frame, showing more clearly the relative position of the members. 7

In the drawings, A designates a suitable support in connection with which my invention has been shown, but it is to be fully understood that I am not limited to this specific application, since the gate may be advantageously used in connection with other types of supports, within the discretion of the user.

10 and 11 designate relativelyspaced upper and lower track members that carry suitably curved arms 12 and 13 that have connection with the support A as designated at 14. At their inner ends, tracks 10 and 11 are.connected by means of a member 15 that also carries a suitably curved arm 16 for connection with the support A, as'at 17. In the present embodiment, the track ways are formed integral with connecting member 15 and are preferably constructed of a length of piping or other material, substantially circular in cross section, whereby the tracks present opposed faces of substantially convex configuration. The purpose of this construction will subsequently appear.

At their forward ends, tracks 10 and '11 are'slightly reduced as at 18 and they are connected by spaced vertically disposed sto members 19 and 20 whose extensions 21 t the side of the reduced portions 18, as clearly illustrated in Fig. 4. After the arrangement of the parts in this position, a suitable fastening member, such as shown at 22 may be passed throughthe extensions 21 and the reduced portion 18, thereby insuring a completely rigid structure.

The gate structure of the present embodiment, consists of a suitably disposed frame 23 covered by a sectionof reticulated material 24, such as wire mesh, the same operatingbetween stop members 19 and 20, as illustrated in Fig. 4. At its rear end, frame 23 carries relativelyspaced hanger bearings 25 and 26 that in turn support guide wheels 27 and 28 which have circumferential grooves fitting the opposed faces of tracks 10 and 11. .At its forward end, frame 23 carries a vertically disposed stop 29 that projects laterally thereof, as in Fig. 4, and

which is designed'to abut against stops 19 and 20 to limit the inward movement of the gate structure, as is obvious.

I also provide the lower track 11 with a supporting bearing 30 adjacent its forward endthat carries a supporting roller 31 which has its circumferential grooved face fitting the lower frame member of the gate in order to support the latter in its true plane, at all times. The rollers 27 and 28 serve to properly support the gate, at all times but by 7 providing the additional supporting roller 31, it is apparent that the strain upon the other rollers, as well as the hanger bearings 25 and 26 is materially relieved. This construction not only insures the longevity of the hanger bearings 25 and 26 but also serves to retain the gate in its true plane, as above stated and prevents the usual sagging thereof. v

From the foregoing, it is believed that the advantages and novel features of my inven tion will, be readily understood and, therefore, further detail description is deemed unnecessary.

In reducing my invention to practice, I find that the form referred to herein as the most practical and preferred embodiment of my invention, is the most efficient,- but realizing that certain conditions will necessarily ,vary in concurrence with the adoption of my device, I desire to emphasize the fact that various minor changes in the de tails of construction and in the proportion of parts may be resorted to when required, without sacrificing any of the advantages of my invention, as defined in the appended claim. 1 v c Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is In oon'ibmation, a support, a member bent to provide upper and lower parallel track elements and a vertical element connecting the rear ends of the track element, said track elements having their outer ends reduced, transversely spaced stop members having lateral extensions overlapping the reduced ends of the track elements and secured thereto, laterally extendingarms connecting the track elements and said vertical element to the support, a gate disposed to operate between the transversely spaced stop members, wheels at the rear end of the gate to travel upon the track elements said gate having a laterally projecting member at its forward end to close the space formed between'the transversely spaced, stop 1nembers and engage the latter and limit the inward sliding movement of the gate, and a roller disposed upon the forward end of the lower track element to act jointly with the wheels at the rear end of the gate to hold the latter in proper position.

In testimony whereof I aflix my signature in presence of two witnesses.
