LATCH MECHANISM FOR SPI'I'TOON-COVERS.

Application filed January 6, 1917.

To all whom it may concern:

Be it known that I, NIooLA Lovnon, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Latch Mechanism for Spittoon-Covers, of which the following is a specification.

It is the object of this invention to provide a novel latch mechanism for use primarily on a sliding cover which houses a spittoon.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

l/Vith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

Serial No. 140,979.

fied by serial number, and consequently, the description may be shortened accordingly, proper notice being given when new elements are described.

In the accompanying drawings, the numeral 1 designates the floor of a building, railway vehicle, steam boat or other structure. In the floor 1 there is an opening 2 enlarged at its upper end to form a recess 3 defining a shoulder 4. Seated in the recess 3 and supported on the shoulder 4 is a base plate 5 including a depending extension 6 located in the opening 2 and provided with a substantially horizontal flange 7. The numeral 8 designates a cuspido-r located within the extension 6 and provided with an outwardly extended flange 9 which, cooperating with the flange 7, serves to support the cuspidor removably. If desired, the cuspidor may be provided with a pivoted bail 16. Upon its upper surface, the base plate 5 is equipped with an upstanding boss 11. By means of securing elements 12, the base plate 5 is attached to the floor 1. Superposed on the base plate 5 is a frame 14 which is U-shaped when viewed in top plan. The frame 14 is secured to the base plate 5 by means of attaching elements 15.

The parts above mentioned duplicate corresponding elements in my copending application above identified by serial number, and need not be described in greater detail.

Mounted to reciprocate beneath the side portions of the frame 14 is a cover 17 which may be reinforced as shown at 18, in any desired manner, so that it will not bend when stood upon. At its rear end, the cover 17 is supplied with a scraper 19, whereby mud may be removed from a boot or shoe. The rear edge of the cover 17 is equipped with a pusher 20 which may be sharpened to form an edge 21. The dirt which is removed by the scraper 19 is carried rearwardly by the edge 21 of the pusher 20, when the cover 17 is retracted, it being ob served that the pusher 20 moves in close contact with the upper surface of the floor 1, as shown in Fig. 2.

In the cover 17 there is formed an opening 23. Superposed on the cover 17 a casing 24 including a base 25, longitudinal upstanding ribs 26 and an end wall 27 hav- 1n thfi base 25 of the casing 24, and this opening is aimed vertically with the opening 28 a notch 28. There is an openin 29 in base plate 34 has a depending stud 35, re ceived in the opening 29 of the part of the casing 24, and in the opening 23 of the cover 17. A cleat 36 is applied to the under face of the cover 17, and extends across and beyond the opening 23. A securing element 37 passes upwardly through the cleat 36 and enters the stud and inthis way, the base plate 34 is held upon the part 25 of the casing 2' 4. Adjacent its forward end, the base plate 34 has a recess 38. Upstanding from the base plate 34 to the rear of the recess 38, and preferably formed integrally with the base plate, is a post 39 provided in its forward edge with an opening 40. Above the opening 40, a slot 41 is formed in the forward edge of the post 39. The post 39 terminates in a rearwardly extended projection 42.

The numeral 43 denotes a lever having wings 44 which lie on opposite sides of the post 39, the wings 44 being connected by a lip 45 which may be formed integrally with the lever 43. The lip 45 is received in the slot 41 of the post 39 when the lever 43 swings toward the post. The lower end of the lever 43 is received in the recess 38'0f the base'plate 34. The lever 43 is equipped at its lower end with an angularly disposed arm 46 carrying a depending latch '47 which on the end portion of the frame 14. When the cover 17 is slid to a closed position, the beveled portion 48 of the latch 47 efiects a raising of the arm 46, and subsequently, thelatch 47 engages with'the keeper 22 to hold the cover 17 in a closed position. The lever 43 is provided with an opening 49 complemental to the opening 40 in the post 39. The

openings

49 and 40 receive the ends of a helical compression spring 50. The spring 50 serves to swing the lever 43 to the left (Fig. 3) until the arm 46, which is received in the notch 28 of the end wall 27, rests upon the end wall, as shown in Fig. 3. The latch 47 thus is positioned in such a way that it will engage automatically with the keeper 22, when the cover 17 is pushed to a closed position. Because the lever 43' is supplied with the wings 44 and the lip 45, the spring 50 is housed in and protected. The latch lever 43 is provided wish lateral'trunni'ons 51 adjacent its lower The invention comprisesa pair of side blocks 52 having recesses 53 on their inner sides, the recesses 53 receiving the ribs 26, and defining flanges 54 which engage the outer faces of the ribs. The recesses 53 also define ribs 55 in the side blocks 52, the ribs 55 overhanging the ribs 26. The post 39 is received between the ribs 55. The ribs 55 are provided with lugs 56 which meet along a line 57 (see Fig. 1,) at the rear of the post 39. Securing elements 64 pass through the end wall 30 and engage'the ends of the side blocks 52. The ribs 55 of the side blocks 52 are provided with openings 58 in which the trunnions 51 of the latch lever 43 are mounted. In this way,the latch lever 43 is so supported that it canyswing' in a vertical plane. Screws 59 or other securing elements pass upwardly through the base plate 34 and enter the lugs 56. The side blocks 52 are supplied with openings 60 In practical operation, the operator ex 7 erts pedal pressure agalnst the upper end of the latch lever 43 in the direction of the arrow A of Fig. 3. The latch lever 43 is tilted on its trunnions 51, and the latch 47 is disengaged from the keeper 22. Continued pressure in the direction of the arrow A will cause the cover 1 7 to be slidr'earwardly, thereby to expose the spittoon 8. When pressure in the direction of the arrow A is relieved from the lever 43,- the lever 43 under the action of the spring 50swings until the arm 46 rests on the end wall 27 within the contour of the notch 28. When the occasion for the use of thespittoon 8 has passed, pressure in a direction opposite to that indicated by the arrow A'niay be applied to the projection 42 which forms part of the post 39. In this manner, the cover 17 may be slid toa closed position above the spittoon 8, the latch 47 interlocking automatically witlrthe keeper 22, and remaining interlockedwith the keeper, due to the action of the spring 50.

The spittoon'8 may be lifted out of the extension 6 at any time, readily, for cleanmg.

Referring particularly to Fig. 2 of the drawing, it will be obvious that when the cover 17 is advanced to a closed position, the.

cleat 36 on'the under side of the cover, cooperating with the boss 11 on the plate 5, serves as a stop for'the cover. I V
