W. E. LAWRENCE. Scraper for Door-Mat.
Patented Dec. 30, 1879.
UNITED STATES PATENT OFFICE.
WILLIAM E. LAWRENCE, OF NEW YORK, N. Y.
IMPROVEMENT IN SCRAPERS FOR DOOR-MATS.
Specification forming part of Letters Patent No. 223, [54. dated December 30, 1879; application filed October 18, 1879.
To all whom it may concern:
Be it known that 1, WILLIAM E. LAWRENCE, of the city, county, and State of New York, have invented an Improvement in Scrapers for Door-Mats, of which the following is a specification.
My invention relates to that class of mats illustrated in the patent granted to C. J. Ferguson on the 26th day of August, 1879; and
my invention consists in constructing the scraper so that it may readily be applied and secured to the mat, whether the latter be of the ordinary form or specially adapted to receive it.
In the drawings forming part of this invention, Figure 1 shows, in perspective, a doormat and scraper applied thereto; Fig 2, a transverse section of Fig. 1; Fig. 3, a perspective view of the scraper; and Figs. 4 and 5, sections showing modifications.
The aforesaid patent granted to Ferguson shows and claims a combined mat and scraper, the latter being shown as of peculiar construction. To facilitate and cheapen the manufacture of mats of this character, I make the scraper A of cast metal, in one or more pieces, with a series of upright blades, 5, connected by cross-bars 0, the whole constituting a ribbed frame. To facilitate the attachment of the scraper to the mat, it may be provided with pointed lugs to, projecting upward or downward.
Where the scraper is to be applied to the top of the mat the lugs project downward from the frame, so as to penetrate the pile or face, as shown in Fig. 4.
In some instances the pile of the mat may be cut away, forming a recess for the admission of the scraper, which rests upon the up per face, 01, of the body of the mat, oris supported above the same by the lugs a, which penetrate the back, as shown in Fig. 5.
When it is desired that the scraper shall be inserted from the bottom, the frame is extended to form a lower flange, d, from which the lugs a project upward, and the mat is cut away to form a recess adapted to receive the portion of the scraper that extends above the flange d. When thus applied the body of the mat rests upon the flange d, so that the scraper cannot be lifted through the mat while the lugs Ct, as in the other forms, serve to retain the scraper in its position without interfering with its ready removal.
In the form represented in Figs. 1 to 3 the blades b are supported at some distance above the bottom of the mat, leaving a receptacle beneath, in which the scrapings may collect, and a pan may be placed in this receptacle, so as to facilitate the removal of the scrapings; or the bottom and sides of the scraper may be closed, so as to constitute the receptacle.
It will be apparentthat by casting the scrn per in one piece it may be produced very cheaply, and that the construction above described permits it to be readily applied, securely retained, and easily detached when necessary for cleaning.
When it is not required to detach the scraper it may be permanently secured, as, for instance, by bolts 1', as shown in Fig. 5.
I claim-- I 1. The scraper A, consisting of a series of blades, 1), cast together in one piece, and adapted for application to a door-mat, substantially as set forth.
2. The scraper provided with the blades 1), connected together and having lugs a, substantially as set forth.
3. The combination,in the scraperA, of the blades 1), connected together, and the lower horizontal plate or flange, d, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WM. E. LAWRENCE.
