DOOR-MAT.

SPECIFICATION forming part of Letters Patent No. 684,826, dated October 22, 1901.

Application filed October 20, 1900. Serial No. 38,755. (No model) a new and useful Door-Mat, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in door-mats; and. the

object of the same is to provide a simple and effective device of this character having structural features that render it exceptionally useful in removing mud, snow, or ice thatmay become accumulatively caked on the shoe or boot, and which feequently resist removal by an ordinary brush-mat, and also to produce a strong and durable mat of a flexible nature and reversible, of a comparatively inexpensive character.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view of a portion of one form of the improved mat embodying the features of the invention. Figs. 1, 1 and 1 are similar views-of portions of the mat, showing different connecting devices for the links. Fig- 2 is a detail perspective view of a portion of the one end finishing-strip of the mat shownin Fig. 1. Fig. 3 is a detail perspective View of a portion of the marginal strip for the device shown by Fig. 1. Fig. 4 is a detail perspective view of one of the links. Fig. 5 is a top plan view of a modified form of the improved mat. Fig. 5 is a view similar to Fig. 5, showing the members of the modified form of the mat connected by different pivotal devices. Fig. 5 is a view similar to Figs. 5 and 5 showing the members of the modified form of the mat connected by pivotal rivets. Fig. 6 is a detail perspective view of a portion of the marginal strip for the device shown by Fig. 5. Fig. 7 is a plan view of a complete mat having similarly-arranged links.

Similar nu merals of reference areemployed to indicate corresponding parts in the several views. I

Referring to Figs. 1, 1*, 1 1, 2, 3, and 4, the numeral 1 designates a plurality of members or complete 1inks,of oval form,as shown,

or any other desired shape, and constructed from ribbon-steel of suitable strength and crimped to form longitudinally-extending central projections 2. These members have the central portions of the bodies thereof to form transversely-extending barsconnected by rivets 3 or anologous fastenings, and the length of the said bars will depend on the number of the members fastened together andwhich will be. regulable at will. The

projections 2 are apertured, and those formingthe terminals of one link respectively embrace or fit between the devices of a similar character of adjaccntlinks and pivotallyconnected by short rivets 4, Fig. 1,engaging each set of projections individually, or. by longer pins 5,connecting two sets of said projections, Fig. l or by rods 6, oonnectingall the sets of a transverse series, Fig 1, or by rings 7, Fig. 1, the several different forms of connections in some instances being used in one mat or individually throughout the entire mat structure, it being understood that any pivotal means will be employed to arrive atthe result sought. The edges of the members are exposed on opposite sides of the mat, thus making the latter reversible to increase its wearing qualities, and in the use of thefsame the accumulations of mud or other material from a boot or shoe and removed thereby falls within the confines or between the members, and thereby avoids clogging the same and facilitates removing the material thus collected by simply raising the mat from over the same, and the open construction of the members renders it easy to keep the mat itself in clean condition. The members or links 1 are formed of a single piece of the ribbon steel or stock or other suitable stock by doubling the same, as shown, and latercrimped or doubled upon itself at regular intervals to form attaching projections 9, which are connected to the projections at one side of the said outer or edge bar, the extremities 10 of the'said strip being bent in planes at right angles to the main portions of the same and terminally riveted to the central portions of the end members of the said latter bar. This marginal strip strengthens the mat construction and prevents the portions of the members connected thereto from being crushed down or from catching on articles passing thereover, such as dress-skirts and the like.

In Figs. 5, 5 5 and (i a modified form of the improved mat is shown and comprises a series of bars 11, formed also from ribbon-steel and bent at intervals to provide trapezoidal loops 12, having the smaller portions of one set fitted in and pivotally connected to the wider portions of an adjacent set, pivotal connection being obtained through the use of rods, pins, or rivets, and to completely close the one end or side of this form of the improved device, as shown by Fig. 5, individual trapezoidal loops 13 are reversed and closely fitted in and secured rigidly to the normally open loops of the bar at the side or end. The modified form of the device'just described also has two sets of working edges and is thus made reversible, and in both forms of the device the bars are free to move in relation to each other with obvious material advantage.

In both forms of the device in addition to the closing means along one margin a movable finishing-strip is applied, as shown by Figs. 1, 2, 5, and (i, the said strip 14 in the first form consisting of a doubled piece of suitable sheet metal gradually reduced toby a pivot-rod 16. These finishing-strips both permit the mat to be arranged close to a sill or threshold or permit said portion of the mat to run down gradually to a floor-surface to avoid material projection and also prevent persons from stumbling thereover.

Many changes in the form,size, proportions, and minor details may be resorted to other than those noted without departing from the principle of the invention. 7

Having thus described the invention, what is claimed as new is- I 1. A mat of the class set forth composed of a plurality of links formed from single pieces of stock and each intermediately bent to produce opposite sides continuous with each other and forming a closed end, the opposite end of the link being open, whereby the closed ends of one series of links may be inserted in the open ends of an adjacent series of the same, and means for pivotally connecting the engaged ends of the links.

2. A mat of the class set forth composed of a plurality of links made up of single intermediately-bent lengths of flat stock, the one terminal of each link being closed and the other open and both terminals transversely reduced, the closed terminals of the links be ing fitted in the open terminals of adjacent links, means for pivotally connecting the engaged link-terminals,,and means for securing the contiguous side portions of the links to each other.

3. A mat composed of aseries of movablyconnected devices, and a finishing-strip pivotally connected to one series of said devices and consisting of a single piece of doubled sheet metal with the edges of the inner side provided with structural means for connecting portions of the said series of devices thereto, and means for pivotally connecting the said devices and strip.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
