6 Claims; (Cl. 7848) This invention relates broadly to portable tools for performing work such as riveting stamping punching, shearing or pressing, but .morepartic-.
ularly to'improvement in portable fluid actuated riveters with which pressure rather than impacts is applied on the rivet.
Such portable tools, often referred to as' rivet squeezers, are well-known in the art.- They include'a motor housing having a yoke secured to its front end and carrying a riveting die adapted to cooperate with a riveting plunger operated by the motor. In such cases-the dieand plunger are ject laterally furtherfrom the' center axis of the tool, resulting in a cumbersome andunbalanced' front end incapable of reaching. rivets located in' confined places.
In anefiort to overcome this difiicultypthe standard type was-modified toinclude a pair of pivotally mounted jaws each carrying a rivet .dier' movable within an are generally having its cen.-,
ter on the center axis of the tool. Thissecond type of tool, generally referred to as.-allegator type, while enabling the reaching ofv rivets'located further away from the edge of-the.work,--offers serious disadvantagesresulting fromxthe pivotal movement of thecooperating jawsand dies; The rivet squeezed between these dies will often have its head ofiset relative to thecenter axis ofthe- Y rivet... In other words, the pressureapplied on therivet instead of being an axial pressure as that obtained with a standard tool, actually is exerted in oblique direction relative to the-center axis of the rivet, causingthe head of the rivet to be lopsided.
It is therefore an object of this invention. to
produce an improved rivet squeezer offering the advantages of the allegator type of riveters but equipped with parallelly movable jaws enabling.
axial pressure to. be applied on'the rivets.
Another object of this invention is to produce a rivet squeezer equipped with parallelly movable jaws located obliquely withrespect to the handle of the tool, thereby resulting in a compact well balanced front. end enabling the squeezing of rivets in places heretofore inaccessible .by the allegator type of squeezer.
Another object of this invention is to produce a fluid actuated portable rivet squeezer or the like forming a simple and compact assembly which is strong, durable and eificient.
In the drawing:
Fig. 1 is a side elevational view mostly in section with some of the parts cut away to show details of construction of a rivet squeezer embody-- ing the invention.
Fig. 2 is a view similar to Fig. l but showing some of the parts in a different position.
Fig. 3 is a longitudinal sectional view taken in a plane indicated by line 33 in Fig. 2.
Figs. 4, 5, 6 and 7 are cross sectional views taken in planes indicated by lines 44, 5-5, 6-6 and 'Il respectively in Fig. 2.
Referring to the drawing, l0 and I6 represent the two parts of a housing, the part 10 being a cylinder formed at one end with an integral boss l I having slidably therein a throttle valve I! for controlling admission of the pressure fluid in the cylinder. The throttle valve is preferably operated by a latch I3 fastened at one end of a rod M which extends longitudinally through the wall of the cylinder and is terminated by an operating trigger l5. To the inner end of the cylinder I0 is secured a front housing part l6 which toward its front end is substantially of diamond cross sec-"- tional shape as shown in Fig. 5, while the otherend'resembles more closely the cross sectional shape of the cylinder l0.
Slidable within the cylinder part Hi there is a piston 11 actuated toward the front housing part IE by means of pressure fluid such as compressed air controlled by the throttle valve l2 and preferably returned by means of compression springs-- I8.
Rigidly secured to the part l6 and projecting lengthwise fromone end thereof, there are twoparallel plates 29. These platescare especially shape-cl to accommodatecomponent parts of the mechanism about. to bedescribed and have their outer ends united. together by. a solid block form ing a Jaw-2!, which as shown is made an integral part of the platesbut could be detachably secured hereto in any suitableway. Thestationary jaw 21 carries a detachableriveting die 22. Within thew. front housing 16 there are mounted between the. plates.?.&, two rollers 23 each carried by cross pin- 2t supportedby the plates 20 aswellas the side walls of thefronthousing l6 as clearly shown in Fig. 6. These rollers are adapted to be engaged by the straight upper side-.25 of a driving member or wedge 26. attached to.the piston I! for slidable i movement therewith. This wedge extends-be tween the plates 20 and has its lower side 21 enmember 3| is also provided with a guide portion 34 disposed at right angles from the jaw 32 and slidable between the plates where it has oneof its sides engaged by a roller mounted between the plates 20 on a cross pin 36 and its other side engaged by a roller 31 also mounted between the plates 20 on a cross pin 38. In order to hold the member 3| between the plates 20, the guide When the piston I! has reached the end of its working stroke, pressure fiuid previously admitted into the rear end of the cylinder part in is exhausted and the piston and wedge are returned in their original position by means of compression springs i8. Concurrentl the jaw 32 is driven in its original positionby the spring pressed plunger 4| and acts on the lever 22 for also causing the latter to assume the original :position shown in Fig. 1.
Normally the opening of the jaw 32 relative to the jaw 2| is controlled by the latch 44 engaging the-stop 46. When desired, this latch may be rotated in clockwise direction in Fig. 1 by compressing the spring 41, causing the inner end of the jaw to be lifted relative to the stop 46 and enabling further opening Of the jaw 32 until the cross pin 4|] reaches the end of the slot 39, as
Operati0n.With the parts positioned as shown in Fig. 1, when the throttle valve i2 is opened, motive fluid is admitted into the rear end of the cylinder HI and creates pressure on the piston for driving it together with the wedge 26 toward the left in Fig. 1, in which instance the longitudinal movement of the wedge due to the engagement of its'specially shaped side wall 2! with-the roller 28 will cause the pivotal movement of the lever 29 in clockwise direction in Fig. 1, resulting in the rounded end 43 0f the lever to push'the jaw 32 toward the stationary jaw 2|. In this instance, it will be seen that during the initial 'movement of the wedge 26, its relatively sharply inclined portion 52 will cause a rapid pivotal movement of the lever 29 and the consequential rapid movement of the jaw 32 toward the jaw 2|. This initial movement is calculated to bring the riveting die 33 in contact with the work or rivet 53 already engaged by the riveting die 22. Thereafter the roller 28 will be engaged wedge 26 for imparting a slower movement of the jaw 32 toward the jaw 2| resulting in greater pressure of the riveting die 33 against the rivet 53 for upsetting the rivet. During this working stroke of the jaw 32, the guide portion 34 engaged by the rollers 35 and 31 is slidably guided therebetween to maintain the jaw parallel to the jaw 2| and consequently the riveting die 33 coaxial With the die 22.
' by the relatively slow inclined portion 54 of the 1 "shown in Fig. 1.
It will be noted that the distance between the roller 28 and the cross pin 30 of the lever 29 is materially greater than that between the rounded end 43 and the cross pin 30, thereby alfor'ding mechanical advantages or multiplication of power which is transmitted from thewedge 26 to the jaw 32.
From the foregoing description it is apparent that by disposing the jaws so as to form an obtuse angle with the housing, that is, disposing.
them in a manner similar to that of an S wrench, it is possible to increase the depth of the throat or opening between the jaws without necessitating excessive lateral projection of the stationary jaw on one side of the center axis of the tool. Through this novel disposition of the jaws, they extend about equally from opposite sides of the center axis of the'tool, resulting in a compact" and well balanced tool front end.
Although the foregoing description is necessarily of a detailed character, in order to completely set forth the invention, it is to be understood that the specific terminology is not intended to be restrictive or confining and it is to be further-understood that various rearrangements of parts and modifications of structural detail may be resorted to without departing from the scope or spirit of the invention as herein claimed.
