SZING DEVICE Filed oct. 9,V 195e ATTORNEY Patented Dec. 19, 1939 UNITE STAES PATET OFFIQE SIZING DEVICE poration Application October 9, 1936, Serial No. 104,878
3 Claims.
My invention relates to a sizing device of the type which utilizes a stream of fluid directed against a work piece or against an element in contact with the work piece, particularly that portion of the device that engages the piece to be measured and which is known as the caliper.
It is an object oi my invention to provide a caliper which may be used on work pieces having splines, keyways, or other types of interrupted surfaces.
It is a further object of my invention to provide a caliper which is light in weight and easy to manipulate.
A further object of my invention is to provide resilient supporting members for the relatively movable parts of said calipers, such supporting members being exible in one direction and rigid in all other directions.
It is a further object of my invention to urge the work engaging members toward the work piece independently of one another.
It is a further object of my invention to utilize the relative movement of the work engaging members to control a machining operation.
Figure l is an end elevation showing the mechanism for moving the caliper into and out of operative position.
Figure 2 is an end elevation of the caliper.
Figure 3 is a rear view of the caliper.
Figure 4 is a plan view of the caliper.
My invention is designed for use with a sizing device of the type disclosed in my Patent 2,023,777 granted December l0, 1935. Reference to this patent will disclose the application of my device to a machine tool. The present invention is an improvement over the work engaging element of the above mentioned patent.
Numeral i9 indicates a base portion, I i a housing or frame secured to said base portion. An
4o L shaped handle l2 is pivotally mounted in said housing thru a pair of parallel links i3 and lli.
Handle l2 and all associated parts are yieldably held in extreme forward or rearward positions by a spring one end of which is secured to said handle and the other end of which is secured in the housing il. Said extreme positions may be determined by suitably located stops not shown. On one end of said handle is rigidly secured a vertical member i5, to which are at- 50 tached, at spaced intervals, four resilient strips i5, il, i8, and i9. Strips i6 and i8 support an upper work engaging member 20. Strips Il and i9 support a lower work engaging member 2|. Each work engaging member is supported and 55 urged toward the Work independently of the other. Each of said work engaging members is a hardened insert having a straight surface long enough to bridge the open portion of the work piece. Strip I l, forming the upper support for the lower work engaging member is attached to 5 member l5 at a point above that at which the strip IB is attached. Strip I8 is the lower support for the upper work engaging member. When all the strips are in normal position; that is, parallel to each other, the work engaging ele- 10 ments are at the limit of their movement toward the surface of the work. When the caliper is applied to a rough Work piece, the normal relation between the supports and strips is disturbed, but there is a tendency to return to normal posi- 15 tion which keeps the work engaging elements in contact with the work.
Said upper work engaging member has an offset portion in which is inserted a nozzle 22. Said nozzle is connected to a supply of fluid under 20 constant pressure thru line 23. Said lower work engaging member also has an offset portion in the same direction upon which is mounted a U shaped bracket 25, the open end toward the work. The purpose of the U shaped bracketis to 25 transfer the movement of the lower work engaging member around the work piece to the member 24 adjacent the nozzle 22. A member 24 having a convex surface is mounted in the top of said bracket and serves to vary the flow of fluid from 30 nozzle 22 in response to the relative movement of the work engaging member. The position of member 24 relative to the nozzle 22 may be adjusted by expanding or contracting member 25. An adjusting screw 32 determines the limit of approach 35 between member 24 and the nozzle 22. The edges of a resilient disc 26 are inserted in notches 2l in the back of member 25. In the normal position of said disc, which is that shown in Figure 2, there is exerted against the sides of member 0 25 only sufficient force to maintain contact therewith. An adjusting screw 28 mounted in the closed end of member 25, and having a graduated head 2li, serves to flex the disc 26 for expanding the sides of member 25. Said member is sufciently resilient to return to normal position when withdrawal of screw 28 permits disc 26 to return to its original state.
The operation of my device will be apparent from the foregoing description.
Various changes may be made in my device without departing from the spirit of the invention. Therefore, I do not wish to limit myself to what is shown and described in the specification, but only as indicated in the following claims.
I claim: 1. In a device of the kind described a pair of Work engaging elements, means for supporting said elements in Work engaging relation comprising a series of flexible resilient strips normally in parallel relation, the outside strips each being attached to one of the Work engaging elements, the inside strips being mounted so that adjacent inside and outside strips support different Work engaging elements.
2. In a sizing device caliper, a pair of Work engaging elements having opposed parallel Work contacting surfaces, means for maintaining the Work contacting surfaces of each of said Work engaging members in parallel relation during a grinding operation and for urging them inde pendently into contact with a Work piece, the point of contact between the Work surface and the work engaging element lying in a vertical plane passing thru the axis of the Work, including two or more spaced resilient strips connecting each Work engaging member and said support member, said point of contact remaining in said plane regardless of slight movements of said Work engaging members in a horizontal direction as said Work piece approaches finished size.
3. In a sizing device caliper, a pair of Work engaging elements, resilient supporting elements mounted at spaced intervals for supporting each of said work engaging elements independently of the other and by their resilience urging said Work engaging elements into Work engaging relation, a part of an indicator carried by one of said elements, a C shaped member carried by the other of said elements for transmitting the movement or" said element around the Work to a point adjacent said indicator part and precision means for adjusting the opening of said member to accommodate Work or different sizes.
