ILEDVVIN R. ANGELL, OF OREGON CITY, OREGON.

ANTIDRAFT.

Application filed February 27, 1922. Serial No. 539,531.

To all whom it may concern:

Be it known. that I, EDWIN R. ANGELL, a citizen of the United States, and a resident of Oregon City, county of Clackamas, and State of Oregon, have invented a certain new and useful Improvement in Antidrafts, of which the following is a specification.

The object of my invention is to provide cheaper and more effective means for closing the apertures in the floor boards of an automobile thru which the lever brakes opcrate.

It has long been a problem to prevent the heat of an engine in summer time and the cold air in winter, dust and dirt and obnoxious fumes at all times from passing thru the floor boards and into the body of the car.

By my invention I have provided a system of brushes which will close the aperture inn mediately after the lever has been passed thru and will maintain a complete seal for a comparatively long period of time. All of these points and others I have shown in the following drawings, in which:

Fig. 1 is a perspective view showing my invention applied to the foot pedals of an automobile with a part broken away to show the center set of brushes in the aperture. It can readily be seen that the brushes will close immediately after the pedal has passed and provide a seal immediately before it;

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1 and shows the construction of the brushes with a wooden spacer in between the separate rows of brushes;

Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1 and shows how the plate forms are locked with each other;

Fig. 4 is a perspective view of an individual brush unit;

Fig. 5 is a plan View of a single set of brushes with parts broken away to shou inside details and illustrates how the emer gency brake of an auto can. readily pass thru the brushes and they can still maintain a close seal to prevent a draft or any dust from entering into the car; and.

Fig. 6 is a cross section detail view taken on the line 6-6 of Fig. 5 and shows some other details of construction.

The brushes are made in single units. The bristles a are preferably made with a spacer 6 between the separate layers so that there is no bulging as there would be otherwise. They are compressed and held in place by means of a metal strip 0 which holds the bristles in place against the spacer strips. In the construction shown in Fig. 1 a stamped form d is made which has apertures e which are spaced so as to accommodate the movement of the pedals. A smaller piece oil-formed material f closes the end of the apertures in this particular design and holds the form plate d in place and prevents it from spreading apart. The whole plate (Z is fastened to the car boards by means of screws or nails 9. The single plate It shown in Fig. 5 containing an aperture 2' can be fastened to the floor boards with screws 3' or the like. The apertures e and '71 are so spaced that the pedals lc will pass down the center lines 8 which separate the ends of the two separate brushes of the set. The apertures c extend a trifle longer than the length of the motion of the pedals is so that there are always brushes beyond the end of travel of the same. It can readily be seen by looking in thesingle unit apertures i which is shown in Fig. 5, that the lever Z will pass directly on the center linebetween the faces of the brushes and thus a minimum amount of wear will be effected on both of the brushes. There will also be no sagging or distortion of the bristles and thus my improved aperture closing device will be effective for a considerable period of time. This has been the trouble with other devices which attempt to eliminate the draft as soon as they become distorted and worn and therefore do not effectually prevent the objections which they were designed to do.

i I claim:

1. In an automobile vehicle in which the floor boards have apertures in which levers work,- a plurality of brush units each unit separate, the brush units positioned so that the faces of two brushes abut on the center line of travel of said lever in said aperture, two brush units constituting a set to close a single aperture, sets of brushes held in position and enclosed by metal forms having suitable openings, and means for fastening said forms to the floor boards.

2. In an automobile vehicle in which the floor boards have apertures in which levers work, a plurality of brush units, each unit separate and bound with a metal strip and the rows of bristles separated by spacers, the brush units positioned so that the faces of two brushes abut on the center line of travel of said lever in said aperture, two brush units constituting a toclose a single aperture, sets of brushes held in position and enclosed by metal forms having suitable openings, and means for fastening said forms to'the floor boards;
