Abstract
Abstract The invention pertains to improvements to devices for fitting and removing tires, whereby the fitting and removing tool can be moved both horizontally and vertically and is adjustable relative to the dimensions of the wheel rim, characterized by the fact that means are provided which permit aforesaid tool to be clamped in any possible horizontal position; means which permit aforesaid tool to be clamped in any vertical position whatever and means which permit aforesaid tool to be moved over a short distance during the clamping operation, in order to assure that it will clear the rim, whereby aforesaid means are controlled by means of one single handle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
192 words
In a tire fitting and removing apparatus having a base, a wheel holder, an upstanding support on said base and a horizontal beam extending from said support over said wheel holder, the improvement comprising: a tire engaging tool mounted at the lower end of a vertical rod (7), a body (10, 11) with a vertical passage (9) in which said vertical rod (7) is slidably mounted and with a horizontal passage (12) through which said horizontal beam (13) extends and on which beam said body (10, 11) is slidably mounted, first (19, 20, 17) and second (19, 20, 21, 22) operating means (19, 20, 21, 22, 17), first clamping means (18) controlled by and coupled with said first operating means for clamping said horizontal beam (13) in said horizontal passage (12), second clamping means (24-33) controlled by and coupled with said second operating means for clamping said vertical rod (7), said first and second operating means having common control means (19, 20) and third means (35) forming part of said second clamping means for lifting said vertical rod a predetermined height relative to said beam when said second clamping means is operated.
Claim 2
Dependent Claim
192 words
In a tire fitting and removing apparatus having a base, a wheel holder, an upstanding support on said base and a horizontal beam extending from said support over said wheel holder, the improvement comprising: a tire engaging tool mounted at the lower end of a vertical rod (7), a body (10, 11) with a vertical passage (9) in which said vertical rod (7) is slidably mounted and with a horizontal passage (12) through which said horizontal beam (13) extends and on which beam said body (10, 11) is slidably mounted, first (19, 20, 17) and second (19, 20, 21, 22) operating means (19, 20, 21, 22, 17), first clamping means (18) controlled by and coupled with said first operating means for clamping said horizontal beam (13) in said horizontal passage (12), second clamping means (24-33) controlled by and coupled with said second operating means for clamping said vertical rod (7), said first and second operating means having common control means (19, 20) and third means (35) forming part of said second clamping means for lifting said vertical rod a predetermined height relative to said beam when said second clamping means is operated.
Claim 3
Dependent Claim
78 words
Apparatus as defined in claim 1, wherein said second clamping means include a plate (24) having a further passage (34) for said vertical rod (7), said plate (24) being at its one end hingedly coupled (28, 29) to said body and being at its other end provided with a stop member (33) the lower end of which is cooperable with said operating means to pivot said plate to thereby clamp said vertical rod in said further passage (34).
Claim 4
Dependent Claim
52 words
Apparatus as defined in claim 2, wherein said plate (24) is hingedly coupled to said body (10, 12) by means of at least one link (28, 29), this hinged connection being by means of an elongated hole (35) forming said third means, the larger axis of said elongated hole being directed vertically.
Claim 5
Dependent Claim
93 words
Apparatus as defined in claim 1, wherein said second operating means include a pinion (21) having an upper end cooperable with said stop member (32) and a threaded lower end (22) rotatably mounted in a threaded hole in said plate (24), and a gear wheel (19) meshing with said pinion (21) and arranged to rotate said pinion (21) which as a consequence thereof moves upwardly and thereby comes into contact with said stop member (33), whereby said plate (24) is pivoted, said gear wheel being common to said first and second operating means.
Claim 6
Dependent Claim
73 words
Apparatus as defined in claim 1, wherein said first operating means comprises a gear wheel (19) which is common to said first and second operating means and which has a threaded lower rod (17) rotatably mounted in a threaded hole (15) of said body, said threaded hole (15) communicating with said horizontal passage (12) and wherein said first clamping means is formed by the lower end portion (18) of said lower rod (17).
Claim 7
Dependent Claim
13 words
Apparatus as defined in claim 2, wherein said stop member (32) is adjustable.
Claim 8
Dependent Claim
16 words
Apparatus as defined in claim 5, wherein said threaded hole (15) in said body is oblique.
Claim 9
Dependent Claim
25 words
Apparatus as defined in claim 5, wherein said first and second operating means further include a common handle (20) coupled to said gear wheel (19).
Claim 10
Dependent Claim
25 words
Apparatus as defined in claim 5, wherein said first and second operating means further include a common power cylinder coupled to said gear wheel (19).
