Serial No. 481.855.
which will tend to makea firm and rigid engagement between the vacuum cup and the surface to which the same is attached.
In carrying out the invention as generally stated above. itis conten'iplatcd employing a vacuum cup which carries spring arms the ends of which engage with the surface to which the cup is attached and exert a pressure which distends the vacuum chamber of the cup so as to increase the vacumn space of said chamber and thereby cau a more firm and lasting adherence bet ..cen the cup and the surface to which it is attached.
It will be understood, of course that the invention in its practical application is susceptible of structural changes and variations of details, one preferred and practical example of which is shown in the accompanying drawings, wherein Figure 1 is a front view of the improved vacuum supporting device, showing the same in engagement with a window. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a perspective view of the vacuum cup detached from its supporting and distending spring arms. Fig. 4 is a bottom plan View of the distending spring arms.
Referring to the said drawings by numerals. 1 designates the vacuum cup, Which may be of the chambered shape shown with the material of its body tapering to its outer edge, or of any other suitable or preferred shape, the object being to provide a vacuum chamber 2 from which the air is expelled by compressing the cup, after which it is permitted to expand to its normal position or shape while held in contact with the smooth surface to which it is to be attached, in a manner well understood. The tapering formation of the body 1 is preferred, as it greatly facilitates the compressing, or bringing together of the edges 3 of the chamber 2.
The body 1 is provided with a centrally located outstanding, preferably integral, head 4 which may be in the shape of a cylinder, and which is adapted to be forced through an opening centrally located in the body 6 which is provided with a pair of oppositely projecting integral arms 7 and 8. Said arms and the bod are preferably stamped from a single piece of sheet metal and the central. opening 5 of the body is punched and its edges are preferably left in an un tinishcd state so that they will readily bite into the material of the head of the cup 1. The spring arms bulge outwardly at their intermediate portions as indicated at 9 to impart resiliency thereto. The ends of the arms project beyond the edge of the vacuum cup, so that when said arms are in contact with the surface to which the cup is attached, a lifting pressure will be exerted upon the cup, which increases the vacuum space of the vacuum chamber in such a manner as to assure of a more firm engagement between the cup and the window or other surface to which the cup is attached. The arm 8 has its end portion which contacts with the window or other surface rounded and outturned to form a suspending hook it), by means of which articles may be held in a suspended condition. The other arm 7 is provided with a downturned sharpened point 11 which may penetrate an article so as to hold the same between the end of the arm and the surface to which said arm is in contact. It will also be understood that the rounded portion of the arm 8 serves as a clamp to hold an article in engagement with the surface to which the cup is attached. Preferably the sides of the arms have their edges upturned as indicated at 12 which imparts strength thereto.
It will be seen from the foregoing that the cup may be readily formed of rubber or equivalent material molded into the desired shape, and that the arms may be readily stamped from a single piece of material, thus greatly cheapening the production of the device.
Vhat I claim as my invention is 1. A device of the character described, comprising a vacuum cup provided with a centrally-located, outstanding head, a body attached to said head and provided with' oppositely-disposed spring arms, adapted to contact with the surface to which the cup is attached to distend said cu and -a sus-i pending hook carried by one said arms,
2. A- device of the character described comprising a vacuum 'cupv adapted for en gagement with a smooth surface, and spring arms having rigid connection-with the cup, the free ends of-said' arms being adapted to contact with the surface'to which the cup is attached and lift the center-"0f said cup to increase its holdin force, said arms being provided, respective y with a suspending hook and a penetrating hook.
, 3.'A dev1ce of the character described comprising a vacuum cup having a body which tapers to its outer edge and a cen trally located outstanding. head, and a body 4. A vacuum suspending device compris f mg a vacuum cup having a centrally lo engagement with the head o the on ,and' ,spring arms integral with the meta body and each provided wit-ha hook s hap ed end adapted to contact with the surface to which the cupis attached-and exert a lif ting;p' ressure on thecentral portion of the cup to increase the vacuum space of the same.
.5. A device of therharactehdesribed, comprising a vacuum cup, "a i netal 'b qdy mounted on said cup, and opposite1y -p ro'- jecting spring armsccarried by 'said'lio dy, and adapted to contact with the surface to which the cup is attached and thereby increase the vacuumspace of said cup, one of said arms beingprovided with a penetrating hook and the other with asuspending hooin In testimony whereof Ihereunto aflix my signature in presence of two'witnessesl'.
