DRIVEWAY FOR, AUTOMOBILES.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed July 5, 1917. Serial No. 178,801.

To all whom it may concern:

Be it known that we, ANGEL VELo Y FILGUELRA and Pnosrnno LASAGA Y VILLA- VERDE both citizens of the Republic of Cuba, and residents of Habana, Cuba, have invented new and useful Improvements in Driveways for Automobiles, of Which the following is a specification.

This invention relates to improvements in driveways for automobiles or other vehicles.

In order to facilitate the entry of automobiles or other vehicles into garages or similar buildings, the sidewalk adjacent the entrance door of the building is constructed as an inclined plane rising from the level of the street to the level of the threshold of the building, which is usually at a level with the sidewalk. This partial interruptionof the sidewalk in front of the entrance doors to these buildings causes a good deal of inconvenience to pedestrians, and may lead to accidents, especially at night. The provision of short permanently located skids leading from the sidewalk to the street proves even more of an inconvenience, as they not only project into, and obstruct part of the driveway, but are likely to cause accidents to pedestrians as well as to draft animals or to drivers of self-propelled vehicles.

An object of the present invention is to eliminate these disadvantages by combining with a portion of sidewalk adjacent the entrance door of a garage or similar building, skids which ordinarily are inserted into the sidewalk, so as to form a level surface with the same, which may be moved in a position in which they facilitate the ascension of a vehicle upon the sidewalk, and which after use, or at night, may be returned again into non-operative position flush with the level of the walk.

Another object of the invention is to pro vide skids of this character on pivotal supports, about which they may be swung from a position level with the sidewalk to a sloping position facilitating the approach of a vehicle on the sidewalk.

With these and other objects in view, an embodiment of the invention is described in the following specification and is illus trated in the accompanying drawing, wherein Figure 1 is a top plan view of an embodiment of the invention showing the skid in non-operative position;

Fig. 2 is a front edge view of the same combination of sidewalk and removable skids;

Fig. 3 shows, on a larger scale a sectional view, taken on line AB of Fig. 1, through the frame for the skids and through a removable member for retaining a pivot pin in place;

Fig. 4: is a similar sectional view, taken on line C-D of Fig. 1, through the skid in non-operative position and showing, in dotted lines, the skid in a position in which the vehicle may approach the walk;

' Fig. 5 is also, on a larger scale, a sectional view, taken on line EF of Fig. 1 through the frame for the skid and through the skid,

in non-operative position, and

Fig. 6 is a top plan view of the combined sidewalk and skids showing the skids in extended or operative position.

As may be seen from Fig. 1, the sidewalk 19 is provided adjacent its curb edge with a pair of rectangular frames or plates 1, spaced from each other, in opposition to the entrance door, conventionally indicated at 18, a distance large enough to correspond with the average gage or distance between the wheels of a vehicle measured along the axis of the same.

These frames or plates consist of a base portion 2 forming a recess, partly surrounded by side flanges 5 and 6 and a rear flange 7 respectively, the side flanges terminating with the front margin of the recessed plate 1 in the curb edge of the sidewalk or approach 19 to the door 18. The rear flange 7 has a concave fillet, which leads to the plane of the recessed portion 2 in the frame 1. The skid member 9 has at its rear end a fillet 8 corresponding in its radius to the fillet which leads from the flange 7 to the plane of the recessed portion 2, to facilitate the swinging movement of the skid to closing position (shown in full lines in Fig. 1), to attain support of the entire lower surface of the skid when in this position, and to facilitate the ascent of the vehicle on the skid when the skid is extended (dotted lines in Fig. a). The upper surface of the skid, ordinarily at one level with the plane of the sidewalk, may be provided with suitable diagonal intersecting corrugations 10 to prevent pedestrians from slipping on these surfaces, an accident which may readily occur if these skids should be made of metal and should have been worn very smooth bylong continued use. The skids 9 are provided near their front edges with lateral pivot pins 11 and 12 adapted for insertion in suitable openings 13 and 14: in the front portlon of the lateral flanges 5 and 6 of the frame plate 1. I

To facilitate the attachment or removal of the skids whenever the exchange or repair of one of these elements should be necessary, one of these lateral flanges (in Figs. 1 and 6 the flange 5) is provided with a cut-out portion in which may be secured a holding member 15 by means of the screws 16 and 17. This member covers the opening 13 for the pivot pin 11; and as these pivots fit advisably loosely in the corresponding sockets 13 and 14:, it is obvious that upon withdrawal of the screws 16 and 17 and of the holding member 15, the respective skid may be slightly tilted about its longitudinal axis, and the pivot pin 12 can be withdrawn from the corresponding socket 1%; another skid can be inserted in the same way, or the same skid may be reinserted and locked against removal by reinsertion and attachment of the holding member 15. Y

The bottom of the recessed portion 2 is advisably provided with grooves 3 and 4., into which ribs 8 and 4- on the under surface of the pivot plate 9 enter when the plate is in inoperative position within the frame 1. These projections on the under surface of the driveway plate 9 will serve for stabilizing the plate against vibration, and they will also contribute in maintaining the plates 9 in proper alinement, as this alinement is not absolutely assured by the use of the pivots, which naturally are somewhat loose in their sockets.

The operation of the device obviously is very simple. After a recess has been cut into the sidewalk, suitable for permanently receiving the frame 1, which has at its front or curb end an enlarged portion in which the pivotal supports of the skids are mounted, the skids are placed within said frame and the holding member 15 is then fastened down to prevent accidental withdrawal of the skids. l/Vhen in inoperative position each skid rests snugly within the recess 2 of the frame 1, owing to the engagement of the fillet at the flange by the fillet 8, and owing to the engagement of the ribs 3, 4 with the longitudinal grooves 3, 4: in the bottom of the recessed portion 2. WVhen it is desired to drive a vehicle into the building the driver dismounts and swings the skids 9. into the position shown in dotted lines in Fig. 4.. The combined skids 9 and recess 2, continued by the upper surface of the side walk, will then form a slightly sloping approach which the vehicle can readily ascend,

the more so as all portions leading from one plane to the next higher plane have rounded edge portions. After the entry of the vehicl'ein the building, the driver again swings the skids 9 into inoperative position and thereby restores all portions of the sidewalk to their prior plane, avoiding the dangers which otherwise would be due to the provision of permanent skids, permanent inclined planes, or recesses in the walk.

tion, being flush with the curb edge of the sidewalk, the pivot of said plate being adj a-. cent to said front edge. 1

3.
