CLASS 42 b: 13 INT. CLASS G 01 b PATENT TIME FROM 30 JUNE 1460 PROVIDED ON 9 MARCH 1961 PUBLISHED ON 9 MAY) 1961 11-11 Ans. 6361/1960, 30/6 1960Harlin a drawing J L KARLSSON, ORNASUDDEN Tumidove The present invention relates to a thumb claw of the type which consists of two mutually displaceable, graduated shell halves, the outer ends of which are provided with collapsible feeding arms.

Sadana tumklovar, vilka huvudsakligen anvandas vid aptering av timmer, aro tidigare kanda. Pet har emellertid vid dessa kanda anordningar visat sig svart att Ora armor= fallbara p sadant salt, att de dels varit lattmanovrerade och dels stadiga i utfallt Medelst ,foreliggande uppfinning liar astadkommits en tumklove, vars matarmar bade aro lattmanovrerade och besitta stor stadga i utfallt 'Age, vilket ernas genom att matarmarna enligt uppfinningen huvudsakligen aro anordnade att i Mfallt lage under inverkan av en fjader tryckas ned i urtagningar i skalhalvorna. Such thumb hooves, which are mainly used in the fitting of timber, are previously known. However, with these known devices, it has been found to be difficult to fall on such salt, that they have been easy to maneuver and stable in failure. By means of the present invention, a thumb claw has been provided, the feeding arms of which are both easily maneuvered and have a large stability in failure. Age, which is achieved in that the feed arms according to the invention are mainly arranged to be pressed down into recesses in the shell halves under the influence of a spring under the influence of a spring.

En fordelaktig utfOringsform av uppfinningen beskrives med hanvisning, till bifogade ritning, dar fig. 1 visar tunikloven uppifran med lutfallda matarmar. Fig. 2 visar en skalhalvas andparti med urtagningar och en mat-arm med motsvarande asar. An advantageous embodiment of the invention is described with male reference, to the accompanying drawing, in which Fig. 1 shows the tunic leaves from above with sloping feed arms. Fig. 2 shows a duck portion of a shell half with recesses and a food arm with corresponding aces.

Tumkloven bestar av tva graderade skalhalvor 1 och 2, vilka am forenade med varandra genom att den ena skalhalvan 1 ãr forsedd med ett i tvarsnitt laxstjartformigt spar och den andra 2 med i tvarsnitt motsvarande laxstjartformig upphojning. Mararmarna 3 och 4 aro vridbart forenade med skalhalvornas 1 och 2 ytterandar och anordnade att i utfallt rage under inverkan av en fjader 5 tryckas ned i tva mot skalhalvornas 1 och 2 langdriktning vinkelrata spar 6. Mater-mama 3 och 4 aro utformade med motsvarande, med matarmarnas langdriktning parallella, asar 7, vilka rued matarmarna 3 och 4 i utfallt lage nedtryekas i sparen 6 pa skalhalvorna 1 och 2. Dessa spar 6 aro fasade vid tva diagonala horn, sã att matarmarnas 3 och 4 .fallning i riktning mot varandra underlattas, medan de icke fasade hornen utgora stoppanslag 8, som hindra aft matarmarna kunna [alias i riktning fran varandra. The thumb claw consists of two graduated shell halves 1 and 2, which are joined to each other in that one shell half 1 is provided with a salmon tail-shaped groove in cross section and the other 2 with a salmon tail-shaped elevation corresponding in cross section. The marble arms 3 and 4 are rotatably joined to the outer ends of the shell halves 1 and 2 and arranged to be pushed down in two outwardly angled grooves 6 towards the longitudinal direction of the shell halves 1 and 2 under the action of a spring 5. The feeders 3 and 4 are formed with the corresponding, with the longitudinal direction of the feed arms parallel, axes 7, which rued the feed arms 3 and 4 in the extended position are depressed in the grooves 6 on the shell halves 1 and 2. These grooves 6 are bevelled at two diagonal horns, so that the inclination of the feed arms 3 and 4 towards each other is facilitated. , while the non-bevelled horns form stop stops 8, which prevent the feed arms from being able to alias in the direction of each other.

Tumkloven klargores for aptering genom att skalhalvorna dragas ut i riktning frau varandra, varefter matarmarna 3 och 4, vilka da ligga hopfallda mot varandra och langs efter skalhalvorna 1 och 2, vridas utat, tills asarna 7 pa matarmarna 3 och 4 under inverkan av fjadern 5 tryckas ned i sparen. 6. Matarmarna 3 och 4 ha da ett vinkelratt lage mot skalhalvorna 1 och 2 och kvarhallas i detta lage av fjadertrycket. Genom att sparens 6 langd stacker sig over hela skalhalvornas 1 och 2 bredd och genom utformningen av sparen 2 erhaller man stor stabilitet och stadga pa matarmarna 3 och 4 1 utfallt lage och de kunna utsattasstora pakanningar vid mattagningen utan att noggrannheten aventyras. The thumb claws are prepared for adaptation by pulling the shell halves out in the direction of each other, after which the feed arms 3 and 4, which then lie folded towards each other and along the shell halves 1 and 2, are rotated outwards, until the axes 7 on the feed arms 3 and 4 under the action of the spring 5 pressed into the save. The feed arms 3 and 4 then have an angularly directed bearing against the shell halves 1 and 2 and are retained in this bearing by the spring pressure. Because the length of the spade 6 extends over the entire width of the shell halves 1 and 2 and through the design of the spear 2, great stability and stability is obtained on the feed arms 3 and 4.

Claims

Attention:

A thumb claw of the type consisting of two mutually displaceable, graduated shell halves (1, 2), the outer ends of which are provided with collapsible feed arms (3, 4), can be drawn therefrom, the feed arms (3, 4) being arranged that in the resulting layer under the influence of a spring (5) it appears in recesses (6) in the shell halves (1, 2).

Thumb claw according to claim 1, characterized in that the recesses (6) consist of two or more grooves perpendicular to the longitudinal direction of the shell halves (1, 2) and that the feed arms (3, 4) are formed with corresponding axes (7) parallel to the longitudinal direction of the feed arms. .

Thumb claw according to claim 2, characterized in that the edges of the spare (6) are bevelled at two diagonal horns, sa. that the fall of the feed arms (3, 4) in the direction of each other is allowed, while the non-bevelled horns form stop stops (8), which prevent the feed arms (3, 4) from being able to alias in the direction of Iran to each other.
