Patented May 24 1932 I CLIVER C. RITZ-WOLLEB, OF CHICAGO, ILLINOIS SUCTION CUP Application filed November 14, 1931. Serial No. 575,052.
My invention relates to suction cups and has for its object the provision of a new and improved form and arrangement of parts by the use of which a supply of non-volatile 6 sealing agent maybe insured between the cup and the surface upon which the cup is used for preventing the leakage of air into the cup. It is one of the objects of my invention to provide a construction of this type in which a collapsible pocket or chamber is provided for the sealing agent so arranged and positioned that upon the application of the cup into holding position by pressure thereon the pocket shall be collapsed for forcing out the sealing agent into effective sealing position.
To this end, it is one of the objects of my invention to provide an arrangement in which the means providing the pocket projects more or less into the concavity of the dished disc comprising a part of the cup so as to insure at least a partial collapsing of such chamber when the cup is applied. It is another object of my invention to provide an arrangement by reason of which a way of escape for the sealing agent from the pocket into the space thereabout may be maintained when the cup as a whole is distorted and flattened against the surface to which the cup is being applied by reason of the pressure necessary for applying the cup into holding position.
It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the accompanying drawings and are hereinafter specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims. I
In the drawings,-
Fig. 1 is'a side view of my improved cup shown in applied position upon a plate glass such as the windshield of an automobile;
Fig. 2 is a side view of a similar cup in applied position upon a part such as the fenderof an automobile;
Fig. 3 is a side view of my improved cup in normal condition before application into holding position Fig. 4 is a bottom face view of the device as shown in Fig. 3;
Fig. 5 is a vertical sectional view taken at the line 5-5 of Fig. 3;
Fig. 6 is a vertical sectional view similar to Fig. 5 but showing the of the parts when the cup is ing position upon a smooth changed position applied into holdsurface Fig. 7 is an enlarged detail being substantially a section at line 7-7 of Fig. 5
Fig. 8 is a view similar to Fig. 5 but showing an additional cooperating part; and
Fig. 9 is a view similar to Fig. 5 but showing a modified form of construction.
Referring now to Figs. 1
cated by indicates to 7 of the drawings, in which corresponding parts are indithe same reference characters, the dished disc portion of one of my improved devices secured in holding. position upon a piece of plate portion 15 being provided tion 17 on its outer face,
with a bail 18 glass 16, the disc I with a body porsupported from the body portion 17.
In Fig. 2 I have shown an alternative use of one of my improved devices in which a standard 19 is mounted by means of a socket member 20 upon the body 17 of the device for holding the standard in upstanding position.
My device is preferably formed of comparatively soft rubber, tion 15 being formed int the dished disc por-- egrally with the body portion 17, as is clearly shown in Fig. 5. At the center of the disc portion 15 at the concave side thereof, I have provided a chamber or pocket 21 the outer portion of which is formed with comparatively thin pliable rubber wall lapsible. when the plate 23, the walls 22 are portions 22 so as to be readily col- As is clearly indicated in Fig. 6, device is compressed by its a cation to a surface such as the surface of ppli the pressed inwardly so as to very materially diminish the size of the chamber 21.
The device as a whole is fur ther distorted so as to cut down very materially the effective size of the annular groove 24 between the walls of the chamber and the adjacent surface portions Under such circumstances, 22 are pressed very firmly a of the plate 23, with the res of the disc 15. the Wall portions gainst the surface ult that the openvolatile. seah the Chamber 21 is indicated by reference numeral 28. When the cup as shown in Fig. 8 is to be applied in holding position upon a surface, the plug 27 is'to be removed,.whereupon the required ressure is to be applied to the outer face 0 the cup for pressin the air out of the dished disc member. s is above explained, the application of this pressure to the device serves to collapse the chamber 21, serving to force at least a portion of the sealing agent out of the chamber through the openin 25. Even when the device is pressed to t e limit of its motion toward the plate upon which it is being applied a way of escape for the sealing agent is still maintained by reason of the fact that the grooves 26 and 24 are still in communication with the outer end of the'opening 25. The result is that the sealing agent is distributed by pressure along the grooves and is spread by such pressure quite'completely over the face of the disc 15.
In the construction shown in Fig. 9, the outer wall portion 22 of the pocket or chamber is formed imperforate, the opening 25 being omitted while the construction remains otherwise the same. In this construction the non-volatile sealing agent 28 is inserted hypodermically, the resiliency of the material of the wall of the chamber being sufficient for. closing the opening into the chamber after the withdrawal of the hypodermic needle. In this arrangement the sealing agent is preserved very effectively for an indefinitely prolonged period in condition to be efficient for use. When the device of Fig. 9 is to be applied, the outer wall 22 is to be perforated at any desired point along one of the grooves 26 so as to prepare the device for application to a surface with the assurance that the sealing agent will be forced out into position on the inner face of the disc 15 by the pressure incident to the application of the device to a surface.
The sealing agent employed may be silicate of soda, shellac, Vaseline, glycerine, or any other suitable material.
Suction cups embodying my improvements may be supplied with the sealing agent at the factory, and since the agent is effectively sealed in, the devices may be stocked by distributors or dealers for long riods of time without the agent deteriorating or leaking out. Thus it is possible for any person to purchase a suction cu containing the proper amount of a suitab e sealing agent and in a moments time put it into use.
While I prefer to employ the form and arrangement as illustrated in my drawings and as above described, it is to be understood that by invention is not limited to such form except so far as the claims may be so limited by the prior art, it being understood that changes might Well be made from the form as shown without departing from the spirit of my invention.
